16 Psyche is believed to be the core of a dead planet. NASA plans to explore asteroid 16 Psyche – long thought to be the core of a dead planet – in 2022 to determine if it actually contains the precious metal. worth 10 trillion USD, which means making everyone on Earth a billionaire or not. Before that time, however, a new study suggests that 16 Psyche is more than likely just a pile of debris. Research published in the journal Planetary Science shows that 16 Psyche is composed of 82.5% metal, 7% iron content pyroxene and 10.5% carbon chondrite. It can also have a bulk density – i.e. the degree of free space inside – of 35%. These numbers are much lower than previous estimates that said it could contain up to 95% metals, mainly iron, nickel and gold. NASA has planned to probe the asteroid 16 Psyche, which is said to be filled with iron, gold, nickel and platinum, in 2022. The study’s lead author, David Cantillo, a senior at UA Arizona University, said in a statement: “The drop in metal content and bulk density is interesting because it shows that 16 Psyche is very strong. different than previously thought”. “It would come as a surprise to see Psyche as a pile of debris, but our data continue to show low bulk density estimates despite its high metal content,” Cantillo said. If the “gold-filled” asteroid was more like a wreck and had less metal inside, as Cantillo and other researchers believe, it wouldn’t be that different from other asteroids in the Solar System, for example. like the asteroid Bennu. Now, NASA’s OSIRIS-REx mission recently embarked on a 2.2 billion-kilometer journey back to Earth after collecting nearly 1kg of rock and dust from Bennu, which could help shed light on how the Solar System formed. . To arrive at their new discovery, the researchers reconstructed the surface of 16 Psyche in the lab, mixing the different ingredients until the patterns of visible light matched those of the asteroid. “Having a lower metal content than previously thought means the asteroid may have collided with asteroids containing more common carbon chondrites, depositing a surface layer,” Cantillo said. that we are observing”. However, NASA notes 16 Psyche remains a major concern for scientists. It is the 16th asteroid discovered on March 17, 1852 by the Italian astronomer, Annibale de Gasparis. 16 Psyche takes about 5 years to orbit the Sun once, but only 4 hours to rotate on its axis, making the day on this asteroid only 1/6th of the day on Earth. According to EarthSky.org, 16 Psyche has a diameter of 182 km, containing 1% of all metals in the asteroid belt. Watch a simulation video of asteroid 16 Psyche (Source Daily Mail) Even if 16 Psyche is worth less than the $10 trillion figure, it’s still valuable to researchers hoping to learn more about what they believe to be the remains of a long-dead planet. . Study author Cantillo said: “The opportunity to study the exposed core of a planet is extremely rare, which is why they sent spacecraft missions there, but our work shows that 16 Psyche is much more interesting than anticipated.” The researchers also believe that there is water on 16 Psyche’s surface, so they will look to merge their data with other missions to asteroids to determine how much water is present. The $117 million spacecraft — which NASA began building in July 2020 — will go into space aboard a SpaceX Falcon Heavy rocket. It is expected to reach asteroid 16 Psyche in the asteroid belt in early 2026. The spacecraft will travel for 21 months in asteroid orbit, mapping and studying the properties of the giant meteorite, with the goal of determining if it is indeed the core of a planet. Asteroid 16 Psyche has long been thought to contain large amounts of iron, nickel, gold and platinum. The Metal World of 16 Psyche 16 Psyche is located in the large asteroid belt between Mars and Jupiter, and may have started as a planet, before it was partially destroyed during the formation of the Solar System. It is now a 200km-wide block of metal, made up of iron, nickel and several other rare metals, including gold, platinum and copper. Thus, it could provide a unique view of the violent collisions that created the Earth and the planets. NASA’s mission will seek to determine whether Psyche was the core of an early planet, how old it is, whether it formed in ways similar to Earth’s core and its surface. how. NASA will send an unmanned spacecraft mission to 16 Psyche, scheduled to launch in August 2022. 16 Psyche, which could be 370 million kilometers away from Earth, is one of the most mysterious objects in our Solar System, and scientists may soon get a close-up look thanks to a newly identified NASA mission take. If the asteroid could be transported back to Earth, the iron alone would be worth $10 trillion. Its value would be large enough to destroy commodity prices and cause the world economy – worth $73.7 trillion – to collapse. Assuming the market for material from asteroid 16 Psyche is returned to Earth, this could cause the value of precious metals to plummet, completely devaluing all holdings including those of governments and all companies engaged in the exploitation, distribution and sale of such commodities.

In the past, all three planets were rocky planets, the surface of which was composed of solid metals and silicates. Among them, our Earth is the largest planet, the mass and radius of Venus is only about 82% and 95% of the Earth, respectively, the mass and radius of Mars only account for about 11% and 53% when compared to our planet. Over the past few decades, humans have launched many unmanned probes to Venus and Mars, and it turns out that the environments on these two planets are very harsh. Venus is too hot, and Mars is too cold, and there is no oxygen on either planet, so life on Earth could not exist in such an environment, and astronomers could not find it. see any other traces of life there. So, how were Venus and Mars 4 billion years ago? Why are Venus and Mars now barren, and only our planet is habitable? Calculated based on the radiant power of the sun, Venus and Mars also operate in the same habitable zone as Earth, which means they can receive just the right amount of solar radiation to water. on their surface can still be in a liquid state. Astronomers speculate based on current signs on Venus and Mars and surmise that there may have been an ocean of liquid water on both Venus and Mars 4 billion years ago. For the first few hundred million years, Venus was a warm and humid planet. In the primordial oceans of Venus, life was fully qualified to evolve. They could be carbon-based life like life on Earth or could be other life forms. However, Venus’s habitable period did not last long. Because Venus is so close to the sun, and the temperature of the sun gradually increases over time, making Venus hotter and hotter, and a large amount of liquid water has also been evaporated. At the same time, the volcanic activity on Venus is also gradually becoming more active and continuously releasing carbon dioxide, causing a strong greenhouse effect. Without oceans, carbon dioxide would not be neutralized. They enter the atmosphere and cause a severe greenhouse effect, which will increase the temperature on Venus. Meanwhile, on Earth, the oceans, plants and minerals absorb large amounts of carbon dioxide, so the Earth will not become too hot due to the strong greenhouse effect during that period. Eventually, Venus’ greenhouse effect was completely out of control, liquid water completely evaporated, and life could have been destroyed. According to data returned by the Venus probe, the current concentration of carbon dioxide in Venus’s atmosphere is as high as 96.5%, and the surface atmospheric pressure is 91 times higher than the Earth’s surface. Under the influence of this extreme greenhouse effect, Venus has essentially reached thermal equilibrium, and the average surface temperature is as high as 464 degrees Celsius. Although it is essentially impossible to have life on the surface of Venus today, some astronomers speculate that there may be some strange life in the atmosphere of Venus. In the sky high enough above the surface of Venus, the atmospheric pressure will be moderate, and the temperature will not be high, possibly for the synthesis of organic matter and the evolution of life. On the other hand, ancient Mars was probably also a habitable planet. Currently, on Mars there is a large amount of water-washed terrain, and there are some iron ores that can only be generated in the aquatic environment, which is strong evidence for the existence of a large amount of water. liquid water on ancient Mars. So, how did Mars become such a uninhabitable planet as it is? At present-day Mars’ North Pole, there is a giant basin whose surface is equivalent to two-fifths of the surface of Mars. This huge Arctic basin was formed by a massive collision. Studies have shown that about 3.9 billion years ago, a dwarf planet (about the size of Pluto) with a diameter of about 2,000 km collided with the north pole of Mars. This massive collision completely changed the core of Mars, causing activities inside Mars to quickly stop, and the Martian magnetic field also gradually weakened and finally almost disappeared. lost. Without the protection of the magnetic field, the solar wind gradually strengthens and melts the atmosphere of Mars, liquid water continues to evaporate, causing Mars to quickly become a barren land. Currently, there is almost no atmosphere on Mars, but there is still some water ice in the polar regions. In addition, there may be a seasonal amount of liquid water in some areas of Mars, which has a high salt content and may be temporarily liquid in the low-temperature Martian environment. At the moment, the temperature on Mars is very low, the average temperature is only -63 degrees Celsius. If humans want to settle on Mars in the future, the first thing to do is to strengthen the star’s magnetic field. Mars and produces large amounts of greenhouse gases to “heat” Mars and melt the solid water that exists on Mars. Mars is much smaller than Earth, so it would have cooled from its molten state at its inception faster than Earth, so liquid water on Mars may have appeared earlier, which could This means that life on Mars may have formed and evolved earlier than our planet. Therefore, there are conspiracy theories that, when celestial bodies collided with Mars, the rocks that were thrown into space by the collisions could have carried the germ of life on Mars into space, and then some someday fall to Earth, becoming the source of life on Earth. And perhaps by coincidence, life on Earth also began to form around the same time that Mars’ North Pole collided. From the point of view of time, this is consistent. In addition, astronomers have discovered traces of suspected life in meteorites on Mars that have fallen to Earth. Life on Earth may have originated on Mars, but this has so far required more convincing evidence. In the past, the Curiosity rover has detected some carbon-containing organic substances in the rocks on Mars, which may be evidence that ancient Mars once had a few living things. Even now, it is still possible for life on Mars, they did not go extinct billions of years ago, but moved into the Martian underground and developed a unique survival mechanism to adapt to the harsh environment. harsh on this planet. Compared to Venus and Mars, our planet is very lucky. For billions of years, Earth has always been a habitable planet, so hundreds of millions of species have appeared here. Our Earth is like a “chosen planet”, a moderate distance from the sun, with a magnetic field that can resist solar radiation so that all kinds of life can continue to multiply and develop. Although it cannot be ruled out that some planets in the solar system (such as Europa) also harbor life, the environments of those planets are very different from those of Earth, and most life on Earth is not ruled out. Soil cannot exist there. In the near future, Earth will still be the only planet inhabited by humans in the universe.

For the past four billion years, life on Earth has been endless. But now on Earth there are only nearly 10 million species of creatures, this number is only 1% of the total number of species that have ever lived on Earth, the remaining 99% has disappeared in the long river of the Earth. Although our planet is a vibrant planet, it is very difficult for any living species to survive long on Earth. Over time, the Earth’s climate will continue to change and some ancient species have been unable to adapt to this change, leading to extinction. In addition, life on Earth could also be threatened by deadly threats from space. For example, a gamma-ray burst from a supernova could destroy Earth’s atmosphere and cause deadly cosmic radiation to reach our planet’s surface. Most life on Earth wouldn’t be able to withstand this. 450 million years ago a supernova caused the first mass extinction of the space threat on Earth. On the other hand, the impact of a giant asteroid falling to Earth will also cause drastic changes in climate, disrupt the food chain and cause mass death for life on Earth. The fifth mass extinction 65 million years ago was probably also caused by an asteroid collision. In addition to the threat from space, on Earth there may be superbugs that humans can’t fight off. Humanity also possesses nuclear weapons capable of destroying all life on Earth. Although humanity has enough intelligence to create such a powerful weapon, it is not known if humanity is intelligent enough to not use nuclear bombs on a large scale. And also for various reasons, Hawking believes that in order to continue to exist, humanity must expand its habitat into space in the future. Only by taking precautions and leaving Earth before disaster strikes and colonizing other planets can humans better cope with unknown disasters. So which planets should humans migrate to? Is there a “Second Earth” in the universe? Proxima b’s host star is Proxima Centauri – part of a trio of strange stars that scientists are still studying. The other two stars are binary – meaning they orbit the same center of gravity and are collectively known as Alpha Centauri. Although this “Second Earth” has similar properties to the Earth – where we live, Proxima b is still a mysterious and alien world. In the solar system, although life can exist on some satellites, but apart from Earth, there are no planets suitable for human existence. To achieve the goal of space colonization, we can only look beyond the extent of the familiar solar system. Current statistics show that almost every solar system has planets, and there are hundreds of billions of stars in the Milky Way, so there should be multiple targets to choose from. People need to choose rocky planets that are in the habitable zone, because only when the distance between the planet and the sun is neither too close nor too far can liquid water exist on its surface. Proxima b exists right in the middle of the habitable zone of stars, where water could theoretically exist in liquid form. Compared to our sun, Proxima Centauri’s habitable zone is very close to its host star. Scientists once believed that red dwarf stars like Proxima could not exist on habitable planets that were orbiting so close. But now, scientists think red dwarfs might be the best place to look for other habitable planets. And recently, astronomers discovered that Proxima Centauri, the closest star to our solar system, has a planet called Proxima Centauri b. This planet is a rocky planet the size of Earth and it is also in a habitable zone. Although Proxima b is the closest exoplanet to the solar system at a distance of only 4.2 light-years, humans are currently not capable of flying to this planet. Even with today’s fastest spacecraft, if we want to set foot there, it will take us tens of thousands of years to fly to Proxima b. However, humanity has never backed down from difficulties, we have been able to cross the ocean, as well as cross the distant interstellar space to reach the strange world, so it is very possible in the future , people will set foot here.

In 2021, Ian Whyte plays the Plague Doctor in the TV series The Irregulars released by Netflix. On June 15, the magazine GQ published an interview with Ian Whyte. In it, the actor shared about his life, career as well as his impressive roles. First audition In the early 2000s, Ian Whyte was a famous professional basketball player throughout Europe when his first acting opportunity came. “A director came up to me and said, ‘Listen, can you make time for the audition? Because he was exactly the person we were looking for for this role,'” Whyte recalls. The role mentioned is the monster Predator in the movie AVP: Alien vs Predator . Ian Whyte stands with fans dressed as Predator. Photo: RPF. At that time, Whyte had no acting experience. The only advantage he has is that he is similar in height and physique to actor Kevin Peter Hall – the first person to play Predator on screen. After spending an entire weekend scrutinizing the space beast Predator movies, Whyte went to auditions. “It was the hottest day of the year,” he recalls. The audition site was a small studio near King’s Cross Station. They gave me a diving suit with a prop head and a big rope. Then they asked me what I thought. I admit it looks difficult, but I will try.” After Predator, Ian Whyte continued to play many alien creatures, monsters and giants on the screen. He is present in many major Hollywood movie universes such as Alien , Harry Potter , Star Wars and Game of Thrones . “I don’t consider the characters I play to be monsters or beast maniacs. I have always approached them as creatures of character and destiny. They are heroes in their life story,” said Whyte. Roles for a lifetime Sharing about the first role in his career – space hunter Predator of AVP: Alien vs Predator and Alien vs Predator: Requiem – Ian Whyte asserts that Predator is one of the classic, timeless characters. “My wife used to say, ‘You can play as many monstrous roles as you like, I respect that decision. But don’t let it burn you.” Yet one of the first scenes we shot on film was Weyland (Lance Henriksen) burning an oxygen tank and burning Predator alive. In the first week, we had a stuntman to shoot the whole scene. But with the specified angles, they put alcohol on the outfit. So most of the time, I was burning like a torch,” Whyte recalls. Whyte as Last Engineer and director Ridley Scott on the set of Prometheus. Photo: Fox. Role in Harry Potter and the Goblet of Fire (2005) is a completely different challenge for Whyte. In the film, he and actress Frances de la Tour both play Madame Maxime, the two-and-a-half meter tall headmistress of one of the magical schools. On screen, Ian Whyte transformed into Maxime, but from the neck down, in full scenes to bring out the most realistic visual effect. In 2012, director Ridley Scott revived the universe Alien on screen by movie Prometheus . In the film, Ian Whyte plays the Last Engineer. Sharing memories on the set of sci-fi works, Whyte said: “I really enjoyed working with Ridley Scott. I think Prometheus achieved an incredible feat in categorizing brand fans Alien with fans of Scott’s movies. The film has more of Ridley Scott’s breath than a prequel to Alien . It is more contemplative.” To play the Last Engineer, Whyte worked with a female linguist from the university in London. “She spent months developing a new language for extraterrestrials based on a 10,000-year-old ancient language. It included a lot of pops and old voices, which made it quite difficult for me to adapt, ”Whyte shared. Whyte in his first on-screen Predator role. Photo: Fox. In series Star Wars , Ian Whyte stunts for Peter Mayhew – the actor who plays Chewbacca. He thinks Mayhew is a legend: “He brought Chewbacca from nothing to the screen, not only in form but also in humanity, empathy and relatability. His work has become an icon.” With Game of Thrones , Ian Whyte has the role of transforming into many characters of the massive epic franchise. In the first season, Whyte played White Walker. Season two, he becomes Mountain. From seasons three to six, Ian Whyte transforms into several giants. In seasons seven and eight, he put on the disguise of one of the immortals. Of these characters, Whyte said he liked Wun Wun, the giant that appeared in seasons 5 and 6, the most. “He was the first to have human behavior. One who talks less does more. Everything about him is not told or mentioned, but he has a goal to work towards and a purpose to act on,” the actor shared. “I am pleased with his death. A friend of mine pointed out that the detail is reminiscent of a rather old Japanese work titled Throne of Blood . The hero collapsed in a rain of arrows. When I watched the episode with my wife, she asked if I had checked my Twitter account. I don’t pay much attention to social media. And my wife explained ‘People are going crazy over Wun Wun’s death’. I didn’t know this at all because I didn’t think my character would be so popular,” Whyte concluded.

Mars hides the secret of life, always urging people to explore. Photo: NASA Today’s Earthlings are perhaps the most curious generation about the possibility of alien life on Mars, and are always wondering how humans might one day colonize there. From theories about Martian canals to alien radio messages, over the past three centuries, mankind has been constantly thinking about life on Mars. approach to his Martian “brothers”. Mars often appears in ancient texts as a “fire star,” or represents the god of War. In the 17th century, new early telescopes allowed scientists to get a glimpse of the Red Planet. Skilled “channel engineers”? Scientists need more powerful telescopes to be able to see up close, thereby trying to better clarify the hypothesis of life on Mars. In 1877, Italian astronomer Giovanni Schiaparelli noticed crisscrossing lines covering the “Red Planet”. He called these lines “canali”, which means “canal”. Schiaparelli himself does not believe that this is an alien product, but some others are sure of it. Giovanni Schiaparelli’s map of the “canal” system on Mars. Image: Wikimedia Commons As information spread, the word “canali” was translated into English as “canal”, meaning “canal”. And if there were canals, wouldn’t that suggest that aliens would have to dig them? With that argument, many people believe that the interlaced lines on the surface of Mars are a beautiful system of waterways spreading across the planet.. Such a system not only shows that Martians exist, but that they are also amazing engineers. On Earth, it took man 10 years to complete the Suez Canal in 1869. The achievements of the Martians therefore seem to be far superior to those achieved by man. Astronomer Percival Lowell certainly thought so. In 1894, this American scientist-businessman began to expand the concept of a “canal” on Mars. Lowell used his family’s large textile fortune to open the Lowell Observatory in Flagstaff, Arizona, USA. Professor Percival Lowell works with a telescope invested by his family. Image: Wikimedia Commons Percival Lowell mapped the “canals” on Mars with the help of the 24-inch Alvan Clark & ​​Sons refracting telescope he set up at the Lowell Observatory. He made meticulous maps of what was observed on the surface of Mars, wrote many books and regularly gave lectures on his shocking theory that Martians existed and that they were trying to irrigate the planet. their dying elf. Percival Lowell offers logical explanations to answer the question of how and why life exists on Mars. He used the example of life on Earth to illustrate his arguments: “As long as it was proved with certainty that no life could exist on the seabed, dredgers deep sea beds were invented, and before long, they ‘frustrated’ us. Behold, they see full of life. Fish, crustaceans, molluscs and echinoderms. In short, the life of all common floating fish, from protozoa to marine ‘monsters’ – have been found living in the depths of the seabed. What is impossible, turns out to be possible.” But mapping Mars is one thing, and soon scientists are looking for ways to make contact with any life that might exist on the planet. “Message” from the Red Planet In 1899, Lowell’s theory of life on Mars received a “kick” from a prominent scientist: Nikola Tesla. Tesla, then a successful electrical engineer, claimed that he had detected an “inexplicable, faint” signal originating from Mars. Portrait of Nikola Tesla circa 1890. Photo: Wikimedia Commons While conducting experiments with his magnifier at high latitudes atop Pike Peak, Colorado Springs, Tesla claimed that he received “a message from another world, unknown and far away. “. What does that message say? According to Nikola Tesla, it is simply: “ONE – TWO – THREE”. A few years later, on a February 1901 day, in an interview with Collier’s Weekly, inventor Tesla announced that he could communicate with Martians by sending wireless messages to any point. on the “Red Planet”. This is a strange statement, because the successful transmission of radio messages on Earth has only become a reality since December of that year. Tesla doesn’t know what the aliens might look like, but he believes they have adapted to living conditions on Mars. Like Lowell, he suggested that “it is possible that in a frozen planet, such as the presumed conditions on our Moon, intelligent beings could still reside, within it, if not within it. on the surface”. To many people, when humans can receive messages from Mars, we can also send messages, that seems reasonable. In 1909, there were attempts to find a contact with life on Mars. Harvard professor William Henry Pickering proposed sending planetary light signals through a series of reflections produced by a network of 50 giant mirrors. The flashes would continue to flash for several years, allowing the Martians time to develop the necessary means to respond. Professor Pickering’s giant mirror illustration for sending signals to Mars. Photo: Library of Congress “In the hope of receiving such signals again, we must of course assume that Martians, if they exist, have telescopes, eyes, etc., just like humans have on this Earth.” Mr. Pickering said. But the Harvard professor’s plan cost $10 million, and no one wanted to fund it.

Photo: NASA The word “telepathy” with Martians… Then, a John Hopkins University professor named Robert Wood suggested covering the white alkaline earth plains of Nevada (USA) with giant black spots made of square kilometers of black cloth. “It might be easier to ‘blink’ the signals with dark spots like a mirror of the same size,” explains Mr. Wood. But like Professor Pickering’s plan, Mr Wood’s solution soon fell through due to a lack of funding. Another professor, David Todd of Amherst University, thinks that by raising a balloon 15,000 meters, he can get any message from Mars. “If life really did exist on Mars, they would have tried for years to talk to us, and perhaps wonder how stupid our behavior was for not responding to them,” said Todd. spoke in May 1909, months before the proposed flight was in September. The Tacoma Times reported on Professor David Todd’s plan for a hot air balloon to capture Mars signals on June 14, 1909. Photo: Library of Congress But Professor Todd’s balloon test flight only reached an altitude of 1,500 meters. Soon after, the support that David Todd received from the US War Department abruptly ended, leaving the scientist with no means to continue with his plan. The use of sound waves, mirrors, hot air balloons, and even giant black spots to “make contact” with any possible life on Mars has at least the backing of science. But on October 27, 1926, a London lawyer named Hugh Mansfield Robinson claimed it was “absurd” that he had tried to send a telegram straight to Mars, which is 56 million miles away from us. km, where “Mars girlfriend” is waiting for him! Dr. Robinson is confident that his message will reach the recipient. Mars was then closest to Earth in its two-year orbit. In addition, Robinson said he had a “telepathic” conversation with a six-meter-tall Martian woman named Oomaruru. According to Dr. Robinson, Oomaruru and her Martians live like Earthlings, driving cars and smoking pipes! However, he asserts, they fly through the sky in electric balloons and eat fruit from electric trees. For months before transmitting the message, Robinson worked with the Central London Telegraph Office to send a physical message to his “Mars girlfriend”. Incredibly, the Telegraph Office agreed to send a telegram from Rugby Tower, the most powerful wireless station in the world at the time, at a standard long-distance rate: 18 British cents per word, or about zero. 35 USD. Although the telegraph staff heard no response, Robinson claimed to have heard telepathically from Oomaruru. She told him that the Martians had “sitted for hours to receive the signal”. “They laugh at our scientists because they themselves are completely out of the trouble in the atmosphere, but we are not,” Robinson said. A “selfie” taken by NASA’s Perseverance probe in April 2021. Photo: NASA … to land on the “Red Planet” The ideas of the scientists who came before them seemed far-fetched, but their curiosity and relentless pursuit inspired generations to come. By 1976, the US Space Agency (NASA) had brought the search for life on Mars to the actual surface of the planet via two Viking landers. One of the metabolic reactions conducted by the lander also revealed positive results, suggesting that there may be life on the “Red Planet”. However, those results remain controversial to this day. Subsequent explorations of the landers have provided evidence that Mars may have once been very friendly to life. For example, the Curiosity rover, which landed in 2012, discovered a mountain in the middle of Gale crater on the Red Planet called Mount Sharp. This 4,800-meter-high mountain is formed from layered sedimentary rock, composed of different minerals, and has been formed over time by wind and water, two elements that require an atmosphere to exist. . helicopter (The Ingenuity Helicopter, from the Perseverance probe, has made many flights to Mars). Scientists believe that if there ever was an atmosphere around Mars, then perhaps microorganisms existed billions of years ago while the layers of material were forming, and the “Red Planet” has could have harbored life for about 1 million years. NASA’s Perseverance rover was launched on July 30, 2020 and landed on Mars on February 18, 2021. Most recently, on May 15, 2021, the Tianwen-1 probe and China’s first self-propelled Mars rover, Zhu Rong, successfully landed on the surface of the “Red Planet”. The mission of Thien Van-1 is to land a lander carrying autonomous robots to the surface of Mars to collect data on groundwater sources, looking for signs of ancient life on this planet. Any discoveries by landers from Earth could be microbial, but they will be no less remarkable than the “canal engineers” we had hoped to find on Earth. Mars from the 19th century. Watch part 1 : CHANNEL OF THE ALTERNATIVES

It creates an infinitely curved region of space-time, from which nothing can escape, not even light. Do black holes rotate? This is an interesting but not so simple question that I received in one of my recent lectures. To answer it completely and accurately, we need a clear understanding of the very verifiable properties of black holes as well as about the nature of rotation. To date, the concept of rotating black holes is not new. In fact, every object in the universe, once having a mass large enough to be spherical, will also have a rotation. Since mass exerts gravity, every object tends to compress itself – because its parts attract each other. For small masses, this gravitational compressive force – commonly known as centripetal gravity – is so small that it cannot exert any effect on the object, because it is simply an intermolecular force of cohesion. substance – especially solids – is much larger than it is. But with very large masses, on the other hand, the force of gravity is so great that matter will rearrange until it becomes spherical. That is, the state in which the force of gravity directed at the center of the object from all directions is equal to each other. That’s how every object as large as a planet or a star gets its spherical shape. At the same time, when there is such a large mass, another problem arises, and also related to gravity. Since no single star or planet is perfectly uniform, in fact the gravitational forces in their different regions are unequal. This difference is the main reason they oscillate, and hence the rotation. Thus, all large objects in the universe rotate because of their own gravity. What about black holes? The most common types of black holes known to scientists today are stellar-mass black holes. It is formed from the late-life contraction of the cores of massive stars. These stars are usually at least 8 to 10 times the mass of the Sun. Towards the end of their lives, their cores shrink very rapidly because the fusion reaction no longer produces enough energy to resist the contraction of that enormous mass. This sudden contraction causes an explosion that is considered one of the most violent events in the universe” supernova explosion. This explosion tore apart the stellar shell that was previously in the state of a red supergiant. The remaining core of the star shrinks and collapses to become a black hole. All stars rotate on their own axis (our Sun, for example, has a rotation period of more than 25 days). It is not difficult to speculate that something formed from a rotating stellar core would also have to rotate, because that momentum is simply still there. The same is probably true of supermassive black holes – black holes with masses ranging from hundreds of thousands to billions of times the Sun, located at the center of most galaxies ever observed. In fact, when the first image of a black hole was released in 2019, scientists were able to see the spirals of the accretion disk surrounding the black hole. It shows that the giant accretion disk is rotating, not fixed. Just like the fact that all the stars in each galaxy are constantly moving around the center of the galaxy (for example, our Sun takes about 230 million years to complete one full circle around the center of the Milky Way). Two things need to be clarified before concluding that the black hole rotates on its own The entire initial mass of the black hole – in theory – is packed into an extremely small singularity. It is so small that it can mathematically be considered sizeless. That singularity has a certain radius (Schwarzchild radius) known as the black hole’s event horizon, but it is just a region of pure space-time, not an object like it has a surface. like a star or a planet. As such, it is difficult to consider something with no dimensions, or a boundary without a surface, to be rotating, since there is simply no alternate motion of points to a particular surface. No radiation comes out from within the event horizon, which also means that all information inside a black hole is unknown. If matter were indeed crushed and completely collapsed into a single point, the space within the event horizon could itself be a place of absolute uniformity, i.e. no rotation would occur due to the difference. interesting. With these two points in mind, don’t forget that what we see spinning is itself just the accretion disk surrounding the black hole. Of course, one can also calculate the rotational speed of an accretion disk based on its mass when taking into account as well as when not taking into account the presence of a black hole at the center, from which to compare and predict. It looks like the black holes in those places are spinning very fast. Even so, given that we don’t know anything about what lies within the event horizon, or even something specific happening at its very edge, concluding that black holes are indeed rotate or not and how fast they rotate is still too early. Likewise, the charge of a black hole is also a purely theoretical concept and is calculated from solving Einstein’s equations. There is no way for us to verify if an electric charge really exists after being swept inside the black hole’s event horizon. In the future, to know more about this information, we will need to look forward to new generations of telescopes and new methods to image and track more black holes with much greater detail. compared to what there are today.

When the Earth’s temperature rose and the amount of oxygen in the oceans decreased about 252 million years ago, most life on our planet suffered the same tragic fate. It is estimated that this extinction event, also known as the “Great Dying”, killed 70% of species on land and about 96% of species in the oceans. Illustration: Getty However, there are no sharks among them. “They’re the last surviving species,” said Elizabeth Sibert, a paleontologist and identifier of fossils and an oceanographer at Yale University. The next extinction event at the end of the Triassic period or even the meteorite event that wiped out the dinosaurs 66 million years ago could not have caused the shark to become extinct. The shark’s survival or longevity is extraordinary, but the animal was also close to the brink of extinction, a study in the journal Science revealed June 3. The study, led by scientist Sibert, shows that a previously unknown extinction event pushed sharks to the brink of extinction 19 million years ago, leaving just one in ten of the sharks. Sharks in the oceans survive. “Something happened and wiped out 90% of the shark population overnight,” said scientist Sibert. The so-called something is still uncertain but it has caused immense destruction. The meteorite that wiped out the dinosaurs on Earth only caused 30-35% of the shark species to be wiped out while the above event was 2-3 times worse. To find this discovery, oceanographer Sibert and his collaborator Leah Rubin went through a remarkable process. Discover the mystery When a marine species dies, its body will fall to the bottom of the sea and decompose into discrete parts. Small parts, such as their teeth, will gradually accumulate in the sediments under the sea. “The seabed is essentially a grave for all aquatic species,” Sibert said. The sediment samples used in this study were collected from two locations in the Pacific Ocean, one in the north and one in the south, covering a period of 40 million years. However, it was not easy to analyze the small teeth inside each of these specimens. These parts are so small, even smaller than the width of a human hair. Oceanographer Sibert filtered dried sediment samples under a microscope and isolated the tiny bits of shark teeth. After separating them, scientist Rubin will identify and describe the features, as well as classify them. These little bits of teeth can reveal a lot to us. There were about 1,300 small tooth pieces identified in the above study with 85 samples with different shapes. Most of them are from the period before 19 million years and only a few samples belong to the later period. So, the question arises, what happened to the sharks? The tip of the iceberg The small tooth fragments suggest a decline in shark numbers and diversity about 19 million years ago, but the cause behind this event is unknown. “This is really a mystery. Right now we don’t know what happened,” Ms. Sibert said. The key to solving this mystery is to learn about the time when the sharks almost disappeared. This period is called the “Miocene” and is described by the scientist Sibert as the “transition phase” of the Earth. 15 million years before the mysterious shark event occurred, the Earth gradually became an “ice house” as permafrost increased in Antarctica. The oceans at that time were no different from the oceans of today, although we cannot find such species as tuna, swordfish and seabirds. Dolphins and whales had not yet evolved. However, there is not much evidence to find out the cause of the shark eradication. Even the discovery, which took place during a rather unusual time in Earth’s history, is just the tip of the iceberg. “There are many questions that need to be answered,” said researcher Rubin. Did some change in the environment lead to the decline in shark populations? This is difficult to confirm because the oxygen and carbon levels show no anomalies, but scientists can use more data around this time stamp. Did the event happen across the oceans and affect other marine species as well? Ms. Sibert said this is a global event but we still need more data. Also, what about other bodies of water? Can sedimentation in lakes and coastal areas occur other phenomena? How were terrestrial species affected during this time? Are there any chemicals that can tell us about the environment then? Ms. Sibert even thought that an epidemic, such as a virus, could be responsible for the decline in shark populations. Still, for this oceanographer, the extinction event was a remarkable phenomenon. The fact that sharks have existed for more than 400 million years, surviving multiple extinction events leads her to believe that something truly intense happened and that the sharks may be the gateway to understanding major changes. collided with Earth during the early Miocene. “There is a lot of data waiting to be discovered,” said researcher Rubin. The discovery not only shows the unpredictable change of the marine environment, but also shows how difficult it is for species to recover when they are pushed to the brink of extinction. “Biology is trying to tell us something and I think we need to listen,” Sibert said.

Hops are an indispensable ingredient in beer production – a wonderful drink that is loved by every country. However, few people know that hops are also used to eat with the most expensive prices in the world. The hops, scientifically known as humulus lupulus, are shaped like the tops of asparagus and are only for the rich to enjoy. In the past, when the beer industry was new, young shoots that did not bloom into flowers were considered waste. Over time, what used to be discarded has become the most expensive vegetable in the world with a price of more than 1,000 USD/kg. The reason why the price of hops shoots is so high is because of the scarcity of this plant. Hops sprout only once in the spring, between March and April. Moreover, the life time of hops shoots is not long. Just a short time after the hops sprout, the hops will quickly perish if not harvested. The expensiveness of hops buds also comes from the sophisticated harvesting process. Hops do not grow in rows, so harvesting must be done entirely by hand. The harvester must carefully find the buds growing in the foliage. They are so small that it takes thousands of hops to fill a bag Garden owners also have to depend on the weather to have a reasonable harvest schedule within 14 days of hops sprouting. They are quite picky about habitat, so they are usually grown only in England and Belgium. Having a shape and taste similar to asparagus when eaten raw, some people think that the hops buds, if eaten raw, are quite bitter, tasting like green beans, but when cooked, it has a very distinct flavor. After being harvested, most of the hops are used by luxury restaurants to cater to privileged diners. Hops shoots can be used for salads, noodles or baked… according to the preferences of the buyer. Sautéing garlic is also an option that many people who have eaten hops appreciate. For many chefs around the world, hops are considered a great ingredient to prepare the unique dishes that make them famous. Please watch the video: The strangest shaped trees in the world.

Photos taken on Mars show many features similar to the glaciers in Antarctica. If these covered glaciers do, in fact, exist, they could be a reason to direct future Mars rovers towards this region. This location is inherently attractive to SpaceX and NASA because it is a wide, flat plain that is ideal for landing spacecraft. If there was ice not too deep below the surface, astronauts could also easily have a source of water within reach. Lead researcher Shannon Hibbard, a doctoral student at the University of Western Ontario, Canada, said the newly discovered flow-like features are very strange because they appear on flat terrain. “There’s a lot of evidence that this is an ice-rich area, but we don’t have any confidence that there could be a glacier in places with tortuous features,” said Hibbard. this. They’re existing in a pretty flat plane, so that’s odd.” Mysterious terrain Arcadia Planitia is located in the northern lowlands of Mars. Over the past 3 billion years, lava flows have been active over this area, so it is much less prone to crater cracking than other areas of the planet. Data collected from orbit over many years shows that the ground in the region is rich in hydrogen. Because water is made of hydrogen and oxygen molecules, this hydrogen indicates the presence of ice just below the surface. For decades, scientists have noticed features on Mars that are associated with ice. Along the low hills, there are debris that looks like the flow of a glacier covered in a thin layer of rock. There are also veins in seagulls that look similar to glaciers flowing through valleys on Earth. Similar features also occur in Arcadia Planitia, says Hibbard. Lobate features occur near a set of mountains known as the Montes Erebus that rise from the plain. Images taken from orbit, thermal data showing the surface’s temperature during both day and night, albedo data showing the surface reflectance, dust cover information and altitude data, and topographic. glacial flow The tortuous features are a big mystery because they look like they were created by the flow of ice, but the terrain isn’t steep enough to explain why the ice moves, says Hibbard. “We had to try to figure out what they are, why do they have thermal symbols, why are they so bright all day and night, why do they have flow characteristics, why are they threaded?” she said. Analysis shows that these features are in fact ice-derived. The undulating shapes look similar to other features associated with slow-moving matter found on Mars, Hibbard said, and the data suggests that these spots are indeed rich in ice. The most similar-looking sinusoidal feature, says Hibbard, is the ice flows inside the Earth’s ice sheets, which are mainly found in Antarctica. These faster-moving ice flows are not well understood on Earth, much less Mars, Hibbard says, but they represent an example of ice flowing in fairly flat terrain. This is a controversial claim, says Hibbard, because most of Earth’s ice streams need at least a thin layer of liquid water at their bottoms to lubricate their flow. It’s not clear if water under the ice exists or ever existed on Mars, she said, and it’s not clear whether a wet background is needed to create ice flows on the Red Planet. One possibility could be that in the past, when Mars’ orbit was tilted differently than it is today and its climate was different, sub-glacial melting may have occurred. The study is published in the May issue of the journal Icarus.

Climate change is one of the main causes of extinctions worldwide. 5 mass extinctions Dinosaurs became extinct in the Jurassic, more than 200 million years ago. * Ordovician-Silurian Extinction: About 440 million years ago The first mass extinction on Earth occurred at a time when organisms such as corals and shellfish filled the world’s shallow waters but had yet to venture to land. Life itself has begun to spread and diversify, first appearing around 3.7 billion years ago. But about 440 million years ago, a climate change caused sea temperatures to shift, and much of the life in the ocean died out. At the end of the Ordovician, mass glaciations covered the southern supercontinent, Gondwana. According to a study published in the journal Oceanology, glaciation on this scale has stripped away high proportions of the world’s water and dramatically lowered global sea levels, depriving the world of vital habitats. species, destroying the food chain and reducing fertility, according to a study published in the journal Oceanology. However, not all scientists agree with this. According to National Geographic, other theories suggest that the toxic metal may have dissolved into seawater during periods of oxygen depletion, wiping out marine life. Other scientists suggest that a gamma-ray burst from a supernova ripped through a giant hole in the ozone layer, allowing deadly ultraviolet radiation to kill life below. According to APS News, there is a Another theory is that volcanoes are the cause. * Late Devonian Extinction: Over 365 million years ago The Devonian period witnessed the rise and fall of many prehistoric marine species. Although by this time animals had already begun to evolve on land, most of life was swimming through the oceans. Until vascular plants, such as trees and flowers, have the potential to cause a second mass extinction. According to the BBC, as plants develop roots, they inadvertently transform the land they inhabit, turning rocks and rubble into soil. This nutrient-rich soil then runs into the world’s oceans, causing algae to bloom on a massive scale. These blooms essentially created giant “dead zones,” areas where algae take oxygen from the water, suffocating marine life and wreaking havoc on the marine food chain. Species that could not adapt to reduced oxygen levels and lack of food died. However, this theory is still being debated, and some scientists believe that volcanic eruptions are responsible for the drop in oxygen levels in the ocean, according to a study in the journal Geology. A species of sea monster that has been wiped out from the world’s oceans is the 10 m long armored fish called Dunkleosteus . * Permian-Triassic extinction: ~253 million years ago This extinction event is the largest event that has ever occurred on Earth. It wiped out about 90% of all species on the planet and wiped out the reptiles, insects and amphibians that roamed the land. What caused this catastrophic event was a period of rampant volcanism. According to the Sam Noble Museum in Oklahoma, in the ocean, rising levels of carbon dioxide dissolve into the water, poisoning marine organisms and depriving them of their oxygen-rich water. Rising sea temperatures also reduce oxygen levels in the water. Corals are one of the hardest hit groups of marine life – it takes 14 million years for oceanic reefs to rebuild as they once were. * Triassic-Jurassic Extinction: About 201 million years ago The Triassic period was the time when dinosaurs began to inhabit the world. Unfortunately, many volcanoes were also erupting at that time. While it’s still not clear exactly why this fourth mass extinction occurred, scientists suggest that massive volcanic activity occurred in an area of ​​the world now covered by the Atlantic Ocean. cover . Similar to the Permian extinction, volcanoes released huge amounts of carbon dioxide, causing climate change and devastating life on Earth. Global temperatures rise, ice melt, sea levels rise and acidification. As a result, many marine and terrestrial species became extinct; These include large prehistoric crocodiles and several species of flying pterosaurs. All dinosaurs were killed in the fifth mass extinction. Scientists estimate that many species that can fly, burrow or dive into the depths of the ocean survive. For instance, the only true descendants of dinosaurs living today are modern-day birds – more than 10,000 species are thought to have descended from survivors. Is the 6th going? According to The Conversation, scientists define a mass extinction when about three-quarters of species die out in a short geological time, i.e. less than 2.8 million years. Currently, humans are in the early stages of the latest mass extinction, which is happening much faster than any other species. According to the International Union for Conservation of Nature (IUCN), since 1970, populations of vertebrate species have decreased by an average of 68% and now more than 35,000 species are considered threatened with extinction. During the 20th century, as many as 543 species of terrestrial vertebrates became extinct, according to a research paper in the journal PNAS. Since the beginning of the industrial revolution in 1760, humans have been a major factor in Earth’s current environmental crisis. From greenhouse gas emissions and ozone depletion to deforestation, plastic piling and the illegal animal trade, humans have been proactively depriving the world of some species and threatening many others. Ecotourism is an industry that drives conservation efforts around the world, but it is on the verge of collapse since global travel restrictions were introduced. Without tourist income, conservationists are having a hard time protecting vulnerable species from poaching, while the COVID-19 pandemic is intensifying. The New York Times reported. Rhinos in Botswana, feral cats in South America and tigers in India have all been targeted in the past year. In the context of the current pandemic, the wildlife market has become the focus of attention for not only being environmentally irresponsible but also potentially endangering human health through infectious diseases. from animals to humans – such as the COVID-19 pandemic. These markets, which trade in live exotic animals or products derived from them, are found all over the world. For example, bear farms in Asia trap 20,000 Asian black bears for bile, leading to a decline in wild populations. Another potential solution to combat extinction could be the cloning of species. In February 2021, scientists revealed they had successfully cloned a black-footed ferret from an animal that died more than 30 years ago. Native to North America, these small mammals were thought to be extinct until a small colony was found in the early 1980s, where they were engaged in breeding and reintroduction programs. across America. The cloning process is similar to that of Dolly the sheep in the early 1990s.

Samples collected by Japan’s Hayabusa-2 probe. Pour mining money in space According to Florian Vidal (researcher at the French Institute of International Relations) and Professor of Physics José Halloy, the acceleration of ecological transition to combat climate change has led to a sharp increase in mineral demand. to service supposedly zero-carbon technologies as well as to maintain existing or newly built infrastructure. While projects to exploit mineral resources are being replicated on Earth, many “new fronts” are also being considered, such as mining in space. Typically, in 2016, the world’s media buzzed with the daring project of exploiting mineral resources on asteroids of the US companies Planetary Resources and Deep Space Industries. When Planetary Resources entered the space industry in the early 2010s, the company’s leaders were ambitious and promised to enter a new stage in the conquest of space with mining. on asteroids. Since 2012, the company’s project has attracted many private investors such as Larry Page and Éric Schmidt – the heads of Google Corporation, and filmmaker James Cameron. Excitement and enthusiasm for the field of space mining from the US has crossed the Atlantic Ocean and spread to the Grand Duchy of Luxembourg. In addition to adapting national legislation, Luxembourg’s diplomatic service has also been mobilized to facilitate the development of an area considered by the government to be strategic. By the summer of 2016, the State of Luxembourg, through the National Corporation for Credit and Investment (SNCI), spent 12 million euros to buy a 10% stake in the American company Planetary Resources. However, two years later, this partnership was broken. When the American company ran into financial difficulties, the Luxembourg government sold their shares at a symbolic price. However, Luxembourg’s participation in the space mineral exploration project has given them an international position to connect the fields of investment and invention and invention. Continuing the policy in this area, Luxembourg later continued to participate in NASA’s Artemis project to return humans to the moon. Japan, another member of the Artemis project, is also interested in the scientific study of the composition of asteroids, which is a step towards exploring potential mineral resources in space. In December 2020, Japan’s Hayabusa-2 space probe returned to Earth after a six-year mission past the asteroid Ryugu. The goal of this science mission was to prove Ryugu could have the primordial components of the solar system, and Hayabusa-2 accomplished the engineering feat of collecting 5.4 grams of matter from Ryugu at a cost 16.4 billion yen (126 million euros). Similarly, on October 20, 2020, Osiris-Rex (a NASA space probe) also performed a 6-second landing mission on asteroid Bennu to collect dust samples (regolith). Osiris-Rex is expected to return to Earth in 2023 with the collected dust sample. The cost of this mission is about $800 million and about $183.5 million for the Atlas V rocket. Perspectives under the sea To cope with the world’s growing mineral demand, undersea mining is often seen as a solution due to the vastness of this space. Among the countries interested in undersea mining is Norway. After 3 years of seabed exploration, making the Nordic country a leader in this new mining industry, in January 2021, the Norwegian Ministry of Oil and Energy announced the possibility of issuing a license from 2023. Mining permits are available to interested businesses, such as allowing Nordic Mining ASA’s Nordic Ocean Resources AS to exploit deep seabeds rich in copper, zinc, cobalt, gold and silver ores. According to many estimates, there is 6.9 million tons of copper on the Norwegian continental shelf. Japan also has similar plans, with the ability to start exploiting the seabed from 2026. In Canada, DeepGreen (based in Vancouver) in 2019 announced to raise an investment of 150 million. USD to begin exploration for mineral resources in a part of the Pacific Ocean. This is a sign of growing confidence in the industry’s future. However, mining depends primarily on the market price of the metal and the reduction in the cost of mining in the marine environment. The consequences of fishing for marine ecosystems are also of great concern. Scientists warn against switching too quickly from exploration to exploitation because humans still have little understanding of the vast undersea environment and life on the seabed. Controversy over regulations The development of mining activities in the new “fronts” mentioned above also poses the need for appropriate regulations to adjust. This is also what the leaders of the countries have seen. Typically, the International Seabed Authority (ISA) has spent many years drafting a Code for Future Undersea Mining – an indispensable tool for monitoring possible mining activities. deployed. Regulating is considered vital to seabed mining in deep waters such as the Clarion-Clipperton Zone (CCZ) which extends from the Hawaiian Islands to the Baja California peninsula and lies on the road. fault of the Pacific Ocean. This vast area is believed to have reserves of 247 million tons of nickel and 226 million tons of copper. However, many studies have shown that hidden in these spaces is a unique biodiversity and their density is reinforced by the presence of multi-needle nodules located at a depth of 4-5 km. Currently, the debate over regulations for these activities is still raging. While the International Seabed Authority recommends a gradual adjustment of regulations on a step-by-step basis when there are actors involved in seabed mining, it is also argued that such a gradual adjustment is slow. Slow, follow reality. Some argue that it will be difficult to modify the rules of conduct once mining has started. Experts say that although the exploitation of the ocean floor does not fully compensate for the activities taking place on land, it is a necessary additional source to meet future needs. But, as with space, deep-sea mining initiatives are posing dilemmas about extracting resources in increasingly remote regions. All opinions are that, whether on land or at sea, the conservation of ecological balance is a criterion to consider mining projects.

Illustration. White shark Jagged jaws and razor-sharp teeth make the great white shark the most feared killer in the ocean. Fast speed, sharp sense of smell makes it easy for great white sharks to defeat most aquatic creatures except giant whales. Sharks can smell blood from a great distance and quickly move to where their prey is injured. Photo:Discovery Adult great white sharks can be up to 4 m long and weigh about 1,100 kg. The great white shark becomes more aggressive when stimulated by the smell of blood, the researchers say. However, this animal does not intend to attack humans. Their poor eyesight causes them to mistake humans for seals or other animals. Great white sharks kill about 100 people every year. Photo:Discovery Killer whales Experts have had the opportunity to debate the hunting behavior of killer whales and come to the conclusion, this relatively complex way of hunting is not as rare as people think. “I’ve seen similar scenes with a number of different species of dolphins in oceans around the world, so I assume killer whales regularly ‘exercise’ complex hunting strategies with For example, with slower swimmers, such as seals and sea lions, killer whales prefer to use their tails to knock their prey out of the water, stunning it and then killing it. victim,” said an oceanographer from the US National Oceanic and Atmospheric Administration (NOAA). So how do killer whales possess superior hunting skills? How cruel are they? We will take a look at a few reasons why killer whales are known as the “cold-blooded” geniuses of the ocean. Saltwater crocodile The saltwater crocodile is the largest living crocodile and amphibian species on earth. They live in northern Australia, some countries in Southeast Asia or Africa. The habitat of this organism is saline rivers or lakes. Their body size can reach 6 m. The saltwater crocodile is the largest crocodile in the world and the largest living reptile in the world. Male saltwater crocodiles have been recorded at 23 feet (7 m) in length and 2,205 pounds (1,000 kg) in weight. Females are much smaller, measuring about 10 feet (3 m) long and weighing 330 pounds (150 kg). Adult saltwater crocodiles have an average of 66 teeth and the largest bite pressure of any animal in the world. The saltwater crocodile’s most feared weapon is a strong tail, large jaws and fast movement speed. They are known for their cunning for their unique hiding style and ability to approach their prey gently. This cheeky animal is ready to attack humans if they get the chance. Saltwater crocodiles kill between 600 and 800 people each year. Photo:Flick This is the largest reptile on the planet and every year they cause the death of more than 2,000 people. Lion Known as the “king of the jungle”, however, lions don’t actually live in the jungle. Instead, their main habitat is the grasslands and plains of Africa. This animal hides under the trees for about 20 hours a day to avoid the heat. They hunt in groups to increase their chances of killing their victims. The African lion is the largest animal of the cat family. Adult males can be from 3 to 3.3 m long. They use speed to chase their prey, pounce on their victim with their sharp claws before knocking it down with a fatal bite to the neck. Usually, the lion will try to separate the victim from the herd before surrounding and killing it. This animal kills about 800 people every year. The lion has many “gifted” physical traits that make it an excellent hunter in the wild. A lion’s vision, for example, is six times more sensitive to light than a human’s, giving it a significant advantage when hunting at night. Its claws can be easily retracted, stretched, and let out. In addition, they have the ability to reach speeds of up to 80 km/h in a very short time and jump as high as more than 10m. In addition to the symbolic roar, lions communicate with each other in the same ways that cats do: through whining and purring. Lions also rub their heads together as an act of bonding and spreading.” home scent.” This scent allows the lions to recognize the members of the pack when a dispute with an opponent occurs. Tiger Fish The tiger fish is the most bloodthirsty carnivore in the world. They breed and thrive on rivers in South America. The tiger fish’s most fearsome weapon is its sharp teeth, with more powerful bites than the T-rex tyrannosaurs if their jaws are as large as the most feared animals of prehistoric times. The teeth of the piranha are hard and have sharp, saw-like edges, making it easy for them to tear their prey. A school of tiger fish can tear large prey in minutes. The red-bellied tigerfish is the most ferocious of the piranhas. Scientists say tiger fish are attracted to the blood of shark-like prey. However, this animal is ready to attack prey hundreds of times larger than their body. There are also many cases of tiger fish attacking people in the wild.

Use a telescope to track the stars. Illustration: IT. Stay away from lights when observing the sky When using a telescope to observe the sky, determine for yourself reasonable objects and choose the right time and place to observe them. Strong light is the enemy of the astronomical observer. Therefore, stay away from city lights. If you are in the city, you can go to the quiet suburbs if possible. Otherwise, you should choose high positions and have a wide viewing angle to limit the effects of light pollution. Which objects are best for you to observe with amateur telescopes? Many young people after completing the telescope with their own hands feel disappointed. Because you have too much hope for a dream glasses without taking into account the reality factor. Remember, even the glasses that cost thousands of dollars that you order from the world’s leading manufacturers cannot allow you to see the colors shown in the photos taken on Google. Also, pay attention only to the brightest and most observable subjects. Which objects are the brightest? Except for the Moon, readers with basic knowledge of astronomy will think of Venus, Jupiter, Mars or Sirius – the brightest star after the planets in the system. However, Venus is not a good object to observe even though it is very bright. All you see is a yellow halo due to its thick and toxic atmosphere. Stars like Sirius, Canopus, although many times brighter than that, they are just distant balloons. It is not a reasonable target for observation through amateur optical telescopes. The best observed objects are the Moon first, followed by Jupiter, Saturn, Mars and a few galaxies, remarkable nebula. Don’t Observe When The Moon Is Full To observe the Moon, adjust the position of the eyepiece accordingly and aim at the vicinity of the semi-dark area during the nights between the 6th, 7th and 11th of the 12th lunar month. The full moon is a bad subject because it is so bright that it will obscure the craters and valleys you can see. You can solve this with a thin layer of glass called a moon filter, which will reduce the light of the Moon as it reaches your face. With industrial-grade telescopes, most have this. As for the homemade glasses, you can also design it yourself using a glass or a piece of blue plastic but still clear enough to see through it. Even so, the Moon should not be observed on full moon nights. Because in addition to it covering itself, it also obscures other attractive objects of observation, except, of course, on full moon days when the lunar eclipse occurs. You should have a map of the visible part of the Moon to compare when observing. These maps are now easy to find on the Internet and simply print out with any black and white printer. To observe the planets, it is best to choose the right time for good results. Planets have a different period than Earth, so they do not have a stable position like the distant star background. The easiest way is to use computer software to check the positions of the planets, or you can use free software downloaded at www.stellarium.org. Do not forget to set the exact location of the user and when you want to observe. It is advisable to choose days that are not full moons because the planets are in relatively high positions. Jupiter is the most observable object through amateur telescopes. Push your eyepiece a little deeper than when looking at the Moon and try to orient the lens because it will disappear instantly if you don’t keep your gaze exactly. Although it is not possible to see the colors as clearly as in the photos online that have been taken with exposure techniques, and through equipment thousands of times more modern than the amateur glasses you own, the colors Basic with brown lines, dark yellow is what you will see, and moreover the 4 Galilean satellites of this planet. Saturn is like Jupiter, just determine the right direction and fix the glass and you will easily observe it. The most interesting thing to look at this planet is its ring. However, it won’t be as colorful as you’re used to seeing in the photos, both the planet and the ring appear pale yellow. Next in the Solar System is Mars. But observing this planet is not very interesting because all you see is a faint red and maybe some black patches with faint ice caps at the poles if the telescope is relatively good. Anyway, this is the only planet in the Solar System that we can see some of its surface through amateur telescopes. One type of object that is very interesting to observe with amateur telescopes or, more neatly, tubes are bright galaxies and nebulae. Remember to push your eyepiece even further towards the objective so that you can observe the celestial bodies at infinity. The first notable is the Andromeda Galaxy (M31), a spiral galaxy. At a distance of nearly 3 million light-years, it emits light strong enough to be seen with the naked eye. Even with a small binocular you can see a band of light that seems to be a combination of countless small bright dots when directed towards it. What you see is billions and billions of suns like our own. Next is the Pleiades star cluster (M45), also known as the stellar group. It is also easy to recognize with the naked eye, it is a small group of 7 brightest stars located right in the constellation Taurus. Through binoculars or small telescopes, it can be clearly seen that it is a blue star cluster with many stars, including 7 brightest stars visible to the naked eye, so it is called the Seven Stars. This is an open cluster in the milky Way located 400 light-years from Earth. Another member you should look out for is the Orion Nebula (M42), an emission nebula with the same galaxy about 1,350 light-years from Earth. The Orion Nebula, although visible to the naked eye, is quite faint.

The company is interested in planting large timber trees. The tropical monsoon climate is a favorable condition for Vietnam to exploit the largest natural wind source in Southeast Asia. With the potential for average wind speeds of more than 10m/s, Vietnam’s territorial waters are in the top 10% of windiest places on the planet. Some wind power plants are rushing to be completed, in parallel with that is promoting afforestation, greening bare hills, bringing more sustainable growth to localities. Energy source to protect the environment Currently, energy generated from fossil fuels accounts for about 67% of the energy supplied to the world, but is polluting the environment with carbon dioxide emissions. Producing wind power with a 20-year-old turbine generates renewable energy (RE), with no carbon dioxide (CO2) emissions. According to calculations by the European Wind Energy Association (EWEA), the potential for wind power installed in Europe by the end of 2007 with a total capacity of 56.5 GW, will avoid the emission of 90 million tons of CO2 to the environment per year. year. This is equivalent to 45 million cars on the road. In addition to being able to cut CO2, wind power also avoids toxic chemical waste such as mercury and other chemicals that pollute the environment. Using wind power will not deplete or destroy natural resources, but also ensure good use of resources from wind potential. According to the United Nations (UN’s Emissions Gap Report 2020), success in managing the transition to green energy will help developing countries take the leap beyond high-emission technologies. CO2, which underpins richer nations. Vietnam with about 97 million people and 6.5-7% GDP growth has seen energy consumption more than double since 2010. Access to reliable, cost-effective energy sources will be a factor. important for sustainable economic growth. Wind Turbine No. 1. Working together for the program “one billion trees” In the orientation and planning of renewable energy development, Nhon Hoi 1 Wind Power Plant and Nhon Hoi 2 Wind Power Plant invested by FICO Binh Dinh Energy Joint Stock Company as an investor are being built at Phuong Mai mountain, area. Nhon Hoi economy, Binh Dinh province. This is one of the areas assessed to have the largest wind power potential in the country. Nhon Hoi 1 Wind Power Plant has a capacity of 30 MW, surveyed, researched and invested on an area of ​​about 175 hectares, with a total investment of more than VND 1,321 billion. Nhon Hoi 2 Wind Power Plant Project has a capacity of 30 MW, surveyed and researched on an area of ​​about 201 hectares, with a total investment of more than 1,249 billion VND. As of May 2021, the factory has basically completed the infrastructure and safe transportation of super-heavy equipment. Compared with other renewable energy sources such as solar power, after installing wind turbines, the area where the wind turbines are located is still used for farming or other agricultural and forestry activities. Mr. Huynh Van Luan, Deputy General Director of FICO Binh Dinh Energy Joint Stock Company, said that the Nhon Hoi Wind Power Plant site is refurbishing the infrastructure and landscape, accelerating the speed of afforestation. The whole project is expected to be completed by the end of August. Due to the steep rocky and windy terrain, Phuong Mai mountain has no large trees, mainly naturally growing low shrubs. The afforestation project of FICO Company invests in afforestation of large timber trees on the entire Phuong Mai mountain, phase 1 of the project to plant 40 hectares of forests will be implemented from April 2021 by Anh Vu Seed Company Limited. Due to the hot season, priority should be given to afforestation in favorable locations first. Plant breeding work and planting site are also actively preparing for mass planting starting from August this year. The selection of plant species must also take into account factors that are suitable for the rocky terrain and harsh sea breezes at Phuong Mai mountain, therefore, the company will research plants suitable for natural conditions, soil, Abundant native trees create lush green forests. Also according to Mr. Huynh Van Luan, afforestation is difficult, care and protection of forests is even more difficult. “In order to implement the project effectively, we have taken into account detailed plans, such as care procedures, pest control, and weed clearance. Particularly for the Phuong Mai mountain afforestation project, the company will prioritize using local workers right from the stage of planting to tending, managing and protecting forests … “, Mr. Luan affirmed.

NASA’s Parker Solar probe has picked up radio signals on Venus. This is the first direct measurement of Venus’s atmosphere in nearly 30 years, and it is quite different from Venus in the past. A study published May 3 confirms that Venus’ upper atmosphere undergoes puzzling changes during a solar cycle, the Sun’s 11-year cycle of activity. This marks the latest clue to why Venus and Earth are so different. Born from similar processes, Earth and Venus are twins (both rocky, similar in size and structure), but the development paths of these two planets have been different since then. born. Venus lacks a magnetic field, and its surface heats up to a temperature hot enough to melt lead, and the spacecraft only lasts a few hours there. Earth-like planets with life? Studying Venus helps scientists understand how the twins evolved and whether Earth-like planets have life. Video enhancement converts the data from Parker Solar’s FIELDS instrument into audio. FIELDS detected a natural, low-frequency radio emission as it passed through Venus’s atmosphere. This helps scientists calculate the density of the planet’s electrically charged upper atmosphere, known as the ionosphere. In just seven minutes when the Parker Solar Probe was closest to Venus – FIELDS detected a natural, low-frequency radio signal. Like Earth, Venus has a layer of electrically charged gas at the upper edge of its atmosphere, called the ionosphere. This sea of ​​charged gas or plasma naturally emits radio waves that can be detected by instruments such as FIELDS. When Collinson and his team identified the signal, they realized the Parker Solar Probe had passed through the upper atmosphere of Venus. The researchers used this radio emission to calculate the density of the ionosphere over which the Parker Solar probe flew. Researchers last obtained direct measurements of Venus’ ionosphere from the Pioneer Venus Orbiter in 1992. At that time, the Sun was near the maximum of the solar cycle. In the years that followed, data from ground-based telescopes showed that great changes were taking place as the Sun entered its quiescent phase, i.e. minimum. While much of the atmosphere remains the same, the ionosphere – at the top, where gases can escape into space – is much thinner during the sun’s minimum. Observations from the recent flight of the Parker Solar probe, which occurred six months after the sun’s last minimum, show that Venus’ ionosphere is much thinner than previous measurements made. during the solar maximum. “When multiple missions confirm the same results, it gives you a lot of fun,” said Robin Ramstad, study co-author and postdoctoral researcher at the US Space and Atmospheric Laboratory. believe that thinning is real.” Understanding why Venus’ ionosphere is so thin near the Sun’s minimum is part of unraveling how Venus reacts to the Sun. This will help researchers determine how Venus, once very Earth-like, became the toxic atmosphere world it is today. For example, the ionosphere of Venus is prone to leakage, which means the escape of energized gases into space. Collecting data on this and other changes in the ionosphere is key to understanding how Venus’s atmosphere has evolved over time. Venus researchers think that data collected from the Parker Solar probe will give them a new perspective on a mysterious planet like Venus, our twin sister to Earth.

Image of floods in Central Vietnam in 2020, one of the natural losses of Vietnam. A global study commissioned by the World Wide Fund for Nature (WWF) and commissioned by the Economist Intelligence Unit (EIU), shows that public interest in nature has increased markedly (16%). ) over the past five years and continues to increase during the Covid-19 pandemic. The figures are released ahead of the United Nations’ International Day of Biodiversity (May 22), the date chosen to increase public understanding and awareness of biodiversity issues. Expressing growing concern about nature People around the world, especially in emerging economies, are becoming more aware of the planet’s environmental crisis. This has impacted their behavior, especially as a wave of what WWF calls an “ecological awakening” is growing. Current trends also show that the behavior of individuals and consumers is affected by these concerns and they demand drastic action to address the loss of nature and biodiversity. The report “Ecological Awakening: Measuring Global Awareness, Participation and Action for Nature” shows that environmental activism is exploding in online media. Over the past four years, mentions of environmental issues on Twitter have increased by 65%, with the topic of nature and biodiversity increasing from 30 million to 50 million. Many influential individuals and entities such as spiritual leaders, politicians and media organizations, news and celebrities, have spoken out for nature, with social media posts. The festival reaches more than 1 billion audiences worldwide. The study also shows that consumers are increasing their interest in nature through Google searches related to this topic, especially in Asian and Latin American countries such as Indonesia (increased). 53%) and India (up 190%). Many consumers around the world are changing their behavior In addition, more and more people are realizing the loss of nature is a serious global problem. Specifically, 96% of people living in Latin America agree with this when surveyed (the region with the highest percentage). This shift from the community reflects a fact worth pondering, as people in developing regions are experiencing more devastating effects from the loss of nature than elsewhere. After an era of protest marches and petitions, now more and more consumers around the world are changing their behavior such as adjusting their buying habits, buying only what is right for them. with their values ​​and needs. The analysis shows a staggering 71% increase in search results for sustainable products since 2016, popular in high-income countries, such as the UK, US, Germany, Australia and Canada. However, this trend is not only found in these economies, but also appears and increases in emerging economies or developing countries such as Indonesia (24%) and Ecuador (120%). This pressure is forcing manufacturing corporations to respond with action, especially in the cosmetic, pharmaceutical, fashion and food sectors. Since 2016, more than 159 million signatures for biodiversity-related campaigns have been collected, along with an increase in the magnitude and frequency of protests worldwide to demand requires decision-makers to take drastic action for the planet and future generations, in the face of growing nature conservation movements. Information about Southeast Asian countries in the report. Immediate action is needed to prevent damage to nature However, despite the tremendous rate of destruction of nature and the threat this devastation poses to the global economy and human health, nature is rarely a high-priority topic. global agendas. “Scientists and economists have understood. The public was well aware. And the solutions are also obvious. Both the community and society are supporting the process of transforming economic models and sustainable development in which the protection of nature is considered a moral obligation, in return for the life that the earth brings as well as the vital service this planet provides to our economy, welfare, health and security. This is truly an historic “ecological awakening” and an opportunity to rebalance man’s relationship with nature,” said Marco Lambertini, WWF International Director General. The loss of nature is increasing humanity’s vulnerability to pandemics, undermining efforts to tackle the climate crisis and threatening livelihoods. Leaders are expected to make key decisions later this year on climate and environmental issues. These decisions could represent an important opportunity to reverse biodiversity loss, ensure nature is restored this decade, and support climate action and the Sustainable Development Goals. According to this report, Vietnam, a country with a high level of biodiversity – joined the Climate Change Working Group of the Association of Southeast Asian Nations (ASEAN) in 2021. As a country As a member, Vietnam will participate in regional initiatives such as preventing ocean plastic waste, initiatives to tackle air pollution and transboundary water pollution.

Chinese people watch the rocket that sent the Tianwen-1 probe into space. Photo: AP The China National Space Administration (CNSA) announced on May 15 that the Tianwen-1 (Tianwen-1) probe had successfully landed on the surface of the “Red Planet”. “China has left its footprints on Mars for the first time, an important step for our field of space exploration,” Xinhua news agency said. The New York Times reported that since 1976, the US has successfully landed on Mars nine times. The Soviet Union in 1971 became the first country to send a lander to the surface of the Red Planet, but the mission was unsuccessful because the probe then stopped transmitting. Recently, China has continuously recorded new space science achievements. On the morning of April 29, China launched the first module to build its own Space Station (CSS). It seems that to catch up with the US and Russia, China’s ambitions do not stop at Mars and the space station. Moon Dream In January 2019, China was the first country to land a probe on the dark side of the Moon. The dark side can be understood as the night side of the Moon while the other side is observable from Earth due to receiving sunlight and is the day side. This is China’s second successful landing on the lunar surface, the first being in 2013. China is the third country in the world to successfully explore the Moon, after the US and Russia. In December 2020, China sent another probe to the Moon, which is Chang’e-5. On December 16, 2020, the Chang’e-5 spacecraft landed in Inner Mongolia carrying samples from the lunar surface. This is the first time scientists have collected samples from the lunar surface, after the Soviet Luna-24 mission in 1976. Moon samples brought back by Chang’e-5 are on display at the National Museum of China in Beijing. Photo: Getty Images China plans to launch three more spacecraft to the Moon by 2027. Beijing’s goal is to establish a base on the Moon that can be accessed by astronauts within the next decade. In March, the Russian space agency Roscosmos said it would cooperate with China in building a research station on the Moon. However, the two countries have yet to announce the details of this coordination plan. Serious competition The fragmentation of China’s Long March 5B missile falling into the Indian Ocean in May has drawn much criticism from international public opinion. In April, this Long March 5B rocket sent the core module into space to build China’s first space station. In the near future, China plans to carry out 11 more launches to complete the space station by the end of 2022. The International Space Station (ISS) jointly developed by Russia, the US and many countries will “retire” in 2024. It is still unclear what will happen next. The US National Aeronautics and Space Administration (NASA) advocates keeping the ISS operational for a few more years. Russia meanwhile announced it would withdraw from 2025. In the event that the ISS is completely shut down, China will be the only country that owns the space station. Accordingly, the Chinese space station named Thien Cung is expected to be able to host three astronauts operating at the same time. China has selected a team of 18 astronauts, including only one woman. The first three astronauts are expected to spend three months in space. Mars and more Model of China’s first space station. Photo: AP China announced that it plans to make one more Mars landing by 2028 and bring samples from the planet back to Earth for study. NASA and the European Space Agency are also embarking on this work in the hope that the US Perseverance probe, which landed on Mars in February, can bring soil and rock from Mars to Earth by 2031. This is said to be more likely to lead to a race between the parties. China also plans to take 10 years to collect samples from the comet. In addition, the country also intends to set up spacecraft to orbit around Venus and Jupiter. By 2024, China plans to launch a space telescope like the US Hubble, which has been in orbit since 1990. On China Space Day (April 24), President Xi Jinping wrote a letter to senior space scientists, encouraging them to “intensify and expand space exploration and rapidly quickly turn China into a space power.

Photo: India Express It is known that on May 15, China confirmed that Tiawen-1 had successfully dropped the Zurong rover to the surface of Mars. This is a historic milestone that makes China the second country to successfully launch a probe on the Red Planet. In the past, only NASA has succeeded in landing and operating probes on the red planet. (The Soviet Mars 3 spacecraft landed on Mars in 1971 and remained in contact for only about 20 seconds.) The landing took place at Utopia Planitia, a flat land on Mars and the same area where NASA’s Viking 2 rover landed in 1976. After landing, the lander dropped the Zhurong rover – Powered six-wheeled robot named after the god of fire in ancient Chinese mythology. The spacecraft carries an integrated toolkit, including two cameras, a Mars subsurface probe radar, a Mars magnetic field detector and a Martian meteorological tracker. “This is the hardest place to land in the solar system,” said Emily Lakdawalla, author of “The Design and Engineering of Curiosity.” China’s success in its first attempt indicates that it is one of the most capable space agencies.” The European Space Agency also tried to land on Mars in 2003, but its Beagle 2 probe had problems.

China said that “Tianwen-1 has been operating normally since it entered the orbit of the Red Planet,” the China National Space Administration (CNSA) said in a statement on the morning of May 15. CNSA revealed that Tianwen-1 has collected a large amount of data and photos taken from the orbit of Mars. Andrew Jones, a journalist covering China’s activities in space, said that Tiawen-1 has been exploring the Utopia Planitia landing site for more than three months while orbiting Mars. Now, after a successful landing, the Zhurong rover will embark on a mission that will last at least three months to study Mars’ climate and geology. “The main mission of the Tiawen-1 mission is to conduct a comprehensive and extensive survey of the entire planet using orbiters and to bring the probes to surface locations of great scientific interest. focused to conduct detailed investigations with precision and high resolution,” the leading scientists wrote in Nature Astronomy last year. It is known that this expedition vehicle weighs about 240kg, nearly double the weight of China’s previous Yuto Moon. The CNSA said last month: “The Mars rover Zhurong is hoped to ignite the fire of China’s interplanetary exploration and guide humanity into the vast unknowns of outer space.” Photo: The Verge Before Tiawen-1 successfully landed on Mars, the United States also successfully landed 5 rovers on the surface of the Red Planet. More recently, on February 20, 2021, NASA’s Perseverance probe passed through the atmosphere of Mars and landed on the planet on a historic mission to recover rocks to help answer the question. whether life ever existed on Mars. Although this CNSA project is more than four decades behind NASA, this success of China shows that its space engineers are rapidly closing the gap with the US. Tiawen-1 marked a big step for China in the field of space exploration. Previously, China also became the first country to successfully land and operate a probe in the dark side of the Moon in 2019. Recently, China also successfully launched its first core module. Chinese space station. In the future, this will be inhabited by groups of astronauts in space. Earlier this year, China, in partnership with Russia, announced plans to build a space station on the surface of the Moon.

Due to the presence of minerals and other resources on the Red Planet, in the future, Mars could be an abundant source. All in all, the initiatives in this direction are impressive, but as always, there are nuances attached to them. Traveling to Mars on 1,000 rockets and creating land for 1 million earthlings as Elon Musk suggests is an extremely expensive and technologically difficult task. It is not necessary to list all the problems that arise when massive scientific works are devoted to this, just to mention the main “knots”. First, There is no technology that allows the creation of spacecraft with the ability to send people into distant space without having to receive a lethal dose of cosmic radiation. This problem could be solved by wrapping lead plates, but would lead to a proportional increase in the mass of the ship and a decrease in its carrying capacity. New engines were needed, but they are now beyond production. Monday, Solar radiation will remain a problem on the Martian surface. The Red Planet, unlike Earth, does not have a magnetic field that protects us from ionizing radiation. Astronauts will not have to walk on red sand dunes like in the movie “Total Recall”, but have to hide in bases hidden deep below the surface. Tuesday, Mars on Mars is cold and has practically no atmosphere, but the radiation background is 2.5 times higher than what astronauts on the ISS can tolerate. It is impossible to live in such conditions without a special space suit. There are also many other problems, but it is clear that expanding living space is an extremely important task for all of humanity, requiring accumulation and huge investments in technology. For this reason, scientists are seriously skeptical of Elon Musk’s initiative, especially when he proposes to carry out thermonuclear bombardments at both poles of the Red Planet. This will lead to higher temperatures, melting glaciers, the formation of liquid water and the release of greenhouse gases, which will create the atmosphere on Mars. After that, the settlers could walk on the surface without the spacesuit. But there is another way of looking at this “terrain” approach. Mathematician Robert Walker calculates that in order to carry out the first part of the plan, which would require at least 1 million nuclear bombs with a capacity of 100 megatons, they would have to be sent to Mars 3,500 a day for seven weeks to achieve. desired results. There are no such large numbers of nuclear weapons on Earth and the lack of means to deliver them to another planet. This is the first thing. Carbon dioxide reserves on Mars would not be enough to create a suitable atmosphere, even if the first problem were solved. Since the Red Planet has no magnetic field, solar radiation will gradually “suck” in the already formed magnetic field. This is the second thing. And finally, for some reason, Elon Musk doesn’t take into account that after so many nuclear explosions, the surface of the planet will be radioactive for a long time, you can’t walk there with a mask oxygen and plant trees. “Nuke Mars” is just a cover for the US to send nuclear weapons into space? In general, Elon Musk’s initiative is a nonsense and he himself cannot help but understand this. But why is this smart man promoting it? The head of Roscosmos – Mr. Dmitry Rogozin tried to answer the question: Anyone who calls for the “terrain” of Mars or other planets is well aware that this is just an excuse for launching nuclear weapons into space, which, if useful, is just to “terrain”. our “Earth. But it’s true, you can’t just send nuclear warheads to Mars. First, they will need to be put into orbit and accumulate somewhere along with the means to send them in large batches. Where is that? Suppose that a circular orbit station, which the United States and its allies are building, will be adapted for this case, with China and Russia as targets. But will the nuclear bomb then make its way to the Red Planet? It’s long been no secret that Elon Musk is working closely with the Pentagon on the space program and satellites. So why not try with the best cause, Mars exploration, to advocate for the idea of ​​​​putting a US nuclear arsenal in space, Mr. Rogozin concluded.

The idea of ​​​​conquering Mars has been a dream of mankind for many years, this could be the first step towards realizing the dream of many science fiction scientists that is to explore outer space. Sending humans to another planet, even within the solar system, has the effect of reducing the risk of a global catastrophe that could destroy life, such as a large asteroid impact or nuclear war. Even in the future, the Red Planet could be an abundant source of resources. Obviously the ambition to travel to Mars is impressive, but there are many doubts and obstacles attached. Tech billionaire Elon Musk put forward the idea of ​​humans traveling to Mars on 1,000 rockets and creating land for 1 million inhabitants, this is clearly an extremely expensive and technologically difficult task. major barriers have been listed. First, Earth science has not yet been able to create spacecraft with the ability to send humans into distant space that is “immune” to deadly cosmic radiation. The solution to this problem could be to wrap lead plates, but that would increase the weight of the ship and reduce its carrying capacity. Engines for spaceships are now well beyond construction. Second, solar radiation is a big problem, the Red Planet is different from Earth in that it doesn’t have a magnetic field protecting it from ionizing radiation. Astronauts will have to hide in bases hidden deep below the surface, not be able to walk freely on the surface. Third, Mars is cold and has no atmosphere, but the radiation background is 2.5 times higher than that of astronauts on the International Space Station ISS. It is impossible to live in such conditions without a special space suit. There are many other problems as well, but it is clear that expanding space into outer space requires accumulation and huge investments in technology. Before this fact, scientists expressed doubts about Elon Musk’s initiative, when he proposed to carry out bombardments with thermonuclear warheads at both poles of the Red Planet. A “fusion attack” would cause glaciers to melt, forming liquid water and releasing greenhouse gases, which help create the atmosphere on Mars. Then the “reclaimers” could walk around without a spacesuit. But mathematician Robert Walker calculates that to carry out the first part of the plan requires at least 1 million nuclear bombs with an explosive yield of 100 Megatons, must be assembled on Mars 3,500 a day for 7 weeks to achieve desired results. There are no such large numbers of nuclear weapons on Earth, and the lack of means to deliver them to another planet, is the first hurdle. CO2 reserves on Mars would not be enough to create a suitable atmosphere, even if the first problem were solved. Since the Red Planet does not have a magnetic field, solar radiation will gradually “suck” the gas that has already formed, which is the second barrier. Finally, Elon Musk does not take into account that after many nuclear explosions, the surface of the planet will be radioactive for a long time, people cannot walk with oxygen masks and plant trees. Elon Musk’s initiative is clearly impractical and perhaps the billionaire himself understands this, but what is his meaning. The head of Russia’s state space corporation Roscosmos – Mr. Dmitry Rogozin made a remarkable remark. “Anyone calling for the reclamation of Mars or other planets is well aware that this is just an excuse for launching nuclear weapons into space for military purposes on Earth.” “It’s true, you can’t just put nuclear warheads on Mars. They need to first be put into orbit and assembled somewhere with the means to send them in large batches.” “Assuming an orbital station being built by the US and its allies will be tailored to target China and Russia. Will nuclear warheads reach the Red Planet then? “It is no secret that Elon Musk is working closely with the Pentagon on the space and satellite program. So why not experiment with the best cause of Mars exploration, to advocate for the idea of ​​​​putting US nuclear weapons in space,” concluded Mr. Rogozin.

The Global Times (China) on the morning of May 15 reported on the successful landing on Mars of the Tianwen 1 mission. According to RT (Russia), the Tianwen 1 (Tianwen-1) spacecraft of the China National Space Administration (CNSA) was successfully launched from Wenchang Launch Site on July 23, 2020 and orbited Mars since February 10 this year. This interplanetary mission is China’s second attempt to reach the “Red Planet” after the 2011 Mars mission of the Huang Huo 1 (Yinghuo-1) probe. Citing CNSA sources, Chinese state media confirmed that the Tianwen 1 spacecraft successfully landed the Zhu Rong (Zurong) rover on the Martian surface on the morning of May 15. Thien Van 1, weighing 5,000kg, includes an orbiter, a lander and a golf cart-sized rover called Chuc Dung, named after an ancient fire god in the god of fire. Chinese phone. Carrying the Chuc Dung rover, the lander endured “seven minutes of horror” as it plowed through the Martian atmosphere on a parachute support lander. The spacecraft landed in Utopia Planitia, the same area where NASA’s Viking 2 mission landed in 1976. Watch a simulation video of the Chinese lander’s landing on Mars: (Source: Global Times) Earlier, in a statement on the same day, CNSA said, “The Tianwen 1 probe has been operating normally since its successful launch on July 23, 2020”. The agency added that it had collected a “massive amount” of scientific data as the Tianwen 1 rover orbited Mars. “With the assessment of the flight status, the Tianwen 1 probe is scheduled to conduct a landing operation against the Utopia Planitia area at the appropriate location from the early morning of May 15 to May 19 according to the Beijing time,” the CNSA statement said. The Utopia Basin is the largest recognized basin on Mars, with a diameter of about 3,300 km. Graphic image of China’s probe landing on Mars.

According to The Verge, China is planning to land a pair of robots on the surface of Mars, making a daring attempt to become the second country to successfully land and operate a rover on Mars. Red Planet. China launched the unmanned Tianwen-1 spacecraft from the southern island of Hainan in July 2020, with the goal of sending a rover to the surface of Mars to collect data about the source groundwater and look for possible signs of ancient life there. So far, only the US has successfully implemented the technique to bring the rover to Mars and operate it. After a journey of nearly 7 months, the Tianwen 1 spacecraft successfully moved into Mars’ orbit on February 10 and then sent back to Earth many high-definition pictures of the Red planet’s surface.

Photo: AFP/Getty Images Model of the Tianwen 1 probe. Photo: AFP The Tianwen 1 mission marks the latest step in China’s rapid succession of advances in space exploration. The country became the first country in history to land and operate a probe on the far side of the Moon in 2019. Beijing also completed a lunar sampling mission last December. , with launching a robot to the Moon and quickly returning it to Earth carrying soil samples. Tianwen 1 is China’s first Mars landing mission, but it’s not the country’s first attempt to send a probe to Mars. The first is a fairy orbiter called Huynh Hoa 1, launched in 2011 with Russia’s Phobos-Grunt mission. This ship did not go beyond Earth orbit after launch, plunged into the Pacific Ocean and was destroyed. Before the successful Mars landing of the Tianwen 1 mission, the US successfully landed 5 rovers on the surface of the Red planet. Most recently, on February 20, 2021, NASA’s Perseverance probe passed through the Martian atmosphere and landed on this planet, with the historic mission of bringing back the rocks to help answer the question. whether life ever existed on Mars. On May 28, 1971, the Soviet Union also launched the Mars probe Mars 3, nine days after its “twin” spacecraft, Mars 2, was launched. Illustration of the Soviet Mars 3 probe on Mars. While making a Mars landing on November 27, 1971, the Mars 2 lander crashed to the Martian surface and disappeared in a dust storm. Then, Mars 3 landed in the Ptolemaic crater area in the southern hemisphere of Mars on December 2 of the same year. At first it seemed that Mars 3’s landing went perfectly, but just 110 seconds after landing, the device disappeared in silence. Since then, the Russians have not received any signal from the ship.

In what form could life on earth end in the end? Photo: Astronomy Some scientists point out that the earliest life on Earth was born about 4 billion years ago. At that time, the Earth was continuously bombarded by space meteors, but life continued strongly. Earth’s history has seen many catastrophes, and each one is like the end of the world. Supernova explosions, asteroid collisions, large-scale volcanic eruptions, sudden climate changes … these events have claimed countless lives. During a number of mass extinction events, most of the species at that time had been wiped out. In the end, however, life still goes on. There will always be new species on Earth, and a new cycle will begin again. Although human life may be unimaginably fragile, turning the entire Earth into a barren land is not so easy. Here are some events that have the potential to wip out all life on Earth (very low probability and not happening in the near future). The impact of asteroids When an asteroid hits Earth, it releases incredible energy. 66 million years ago, an asteroid the size of a city crashed into the Gulf of Mexico and led to the extinction of the dinosaurs. At that time, all other creatures on Earth were almost wiped out. Although human ancestors were not born at that time, it may be the most important event in human history. Without the asteroid impact, dinosaurs could always be the lord of Earth, and other mammals could only exist in their shadow. According to geological records assessment, the frequency of Earth being collided by large asteroids is about 100 million years. However, smaller asteroid effects occur more often. There is even evidence that some people have died from the effects of asteroids over the past few thousand years. In 1888, in Sulaymaniyah, now in Iraq, a meteor strike killed one person and injured another. This is the earliest recorded asteroid accident. But what is the probability that Earth will be hit by a large asteroid? A 2017 study published in Nature has shown that to cause this asteroid must be large enough. Only the largest asteroids in the solar system (like Pallas and Vesta) can do this. Richard Binzel, a professor of planetary science at MIT, said even though an asteroid might one day come and destroy us, the likelihood is very low. Oxygen depletion Fossil of trilobite, one of the earliest arthropods on Earth. Photo: Shutterstock The chances of the latter being slightly higher than the previous. First, let’s go back to long history. Nearly 2.5 billion years ago, Earth went through a period known as the “Great Oxidation Event” – creating oxygen on a global scale. The increase in cyanobacteria causes a huge increase in the amount of oxygen in the atmosphere. Without this event, no oxygen-breathing animals would exist and the biological world would not have been diverse, from low-order monocytes to higher multicellular flora and fauna, including humans. However, about 450 million years ago, one of the most serious extinction events on the planet – the Ordovic -Silur mass extinction occurred. It could be due to the sudden drop in oxygen levels at that time, which lasted for millions of years. But why is this happening? During the Ordovic period, all the continents on Earth were connected to form the supercontinent Gondwana. At that time, most life on Earth existed in the ocean, but plants began to appear on land. At the end of the Ordovic period, the Earth’s climate suddenly changed, causing this supercontinent to be covered with glaciers. The sudden drop in global temperature alone is enough to cause the disappearance of many species. Then, when global oxygen levels plummeted, life on Earth experienced a second wave of extinction. Scientists can find evidence of this drastic change in sediment samples on the seabed. Some researchers believe that glaciers at that time caused a fundamental change in ocean stratification, and that the temperature and oxygen concentration of each layer of seawater differ. However, the exact cause of this significant reduction in oxygen is still being debated. Whatever the reason, more than 80% of the species on Earth disappeared during the Ordovic mass extinction. Such events happened in the past, will history repeat in the future? In fact, a recent study published in Nature Communications has shown that climate change reduces oxygen levels in the ocean, which can cause the extinction of some marine life. Gamma-ray bursts Gamma-ray bursts can originate in binary star systems. Photo: University of Warwick Gamma-ray bursts occur when a giant star dies, explodes like a supernova, and collapses into a black hole. It spits out stream of rays at the speed of light in the universe. Any planet in the path of this stream would lose its atmosphere immediately and be burned. When the gamma rays in the explosion hit the blue planet’s atmosphere, they will cause oxygen and free nitrogen atoms to collide, and some will recombine into N2O compounds, the destroyer. ozone layer. N2O is long-lived in the atmosphere, and they continue to destroy ozone until it falls to the ground through rainfall. If there was a gamma-ray explosion in the Milky Way, it could potentially cause the extinction of a large number of species on Earth. If the gamma-ray burst was aimed in the direction of the Earth, even if it lasted only 10 seconds, it would destroy at least half of the Earth’s ozone layer. Scientific research in recent decades has shown that even a small fraction of the ozone layer is destroyed enough to weaken Earth’s “natural protective layer” and cause serious problems. And if the ozone layer is depleted to a certain extent, the Earth’s food chain will be severely damaged, leading to the extinction of a large number of species. Death of the Sun. As the sun continues to age, more and more energy is released, which could eventually wipe out the oxygen in Earth’s atmosphere. Photo: Nasa A study published in the journal Nature Geoscience in March this year showed that regardless of whether or not a gamma-ray explosion occurs, in about a billion years, most life on Earth will die from lack of oxygen. A team of scientists working with NASA believes that this oxygen-rich atmosphere will not last forever. In a billion years, the activity of the Sun will cause the Earth’s oxygen levels to drop back to the levels they were before the “Great Oxidation Event”. The team describes the last moment before the Earth’s inability to support life as follows: “We find that the deoxygenation of the future is an inevitable consequence of increased heat radiation from the Sun. The exact timing of this process will be governed by the redox flow that changes between the geological mantle and the ocean-atmosphere system and the Earth’s crust. ” Conclusions are made after modeling and running simulation based on the algorithm hundreds of thousands of times. The start time and duration of this process will depend on a variety of factors, and can be as short as 10,000 years. But researchers point out that for Earth, in the end, this fate is inevitable. Fortunately, humanity still has 1 billion years left to find another way out.

Mars probe ship. Generates oxygen on other planets The Perseverance expedition ship of the US Aeronautics and Space Administration (NASA) has just made history. It successfully experimented with converting carbon dioxide gas from the Martian atmosphere into oxygen. This is the first time that oxygen production has been performed on another planet. The Mars experiment using local oxygen resources, called MOXIE, is a device the size of an automobile battery and is placed inside the Perseverance. Massachusetts Institute of Technology (MIT) is the manufacturing unit. MOXIE is made of a heat-resistant material such as a nickel alloy. It is designed to withstand extreme temperatures of up to 800 degrees Celsius. The device is coated with a thin layer of gold to prevent heat and damage to the Perseverance vessel. On the first test run, MOXIE generated 5.4 grams of oxygen – enough for an astronaut to breathe easily for 10 minutes while still performing normal activities. Engineers will conduct additional tests and find ways to increase oxygen production. By design, MOXIE can generate 10 grams of oxygen per hour. NASA expects the development of experimental instruments not only to help generate oxygen for astronauts in the future, but also to help generate large amounts of oxygen to be used as a rocket launcher for the return journey without. must be transported from Earth. The Perseverance expedition landed on Mars on February 18 to perform a mission to search for signs of microbial life on the “Red Planet”. In the coming years, the Perseverance ship aims to collect 30 soil and rock samples to send back to Earth (estimated around 2030) for analysis. Dang Vu Tuan Son, Club of Astronomy and Astronomy of Vietnam, said that oxygen-rich atmosphere should not be seen as steel evidence for life on other planets. Nowadays, to look for signs of life, scientists often use biological structures as guides. Its biological form and life-forming compounds serve as indirect evidence for its presence. On Earth, the oxygen in our atmosphere is one of the most obvious biological characteristics that an alien astronomer can notice. It is only in our atmosphere in such large quantities because plants and bacteria photosynthesize it has been creating it for billions of years. Oxygen is not synonymous with life A new study published April 13 in the journal AGU Advances suggests that terrestrial planets around stars like the Sun can develop oxygen atmospheres without help. from life. This means that detecting oxygen on a planet does not mean that the planet is capable of life. This study uses a computer model that allows scientists to experiment and observe the evolution of a planet. In the first model test, the researchers attempted to accurately reconstruct our Earth. Then they changed the initial conditions to different from what was made up of Earth, and the results they got showed that there are many cases where the planets still contain oxygen but do not require any changes. living. In fact, they have found three main ways for a rocky planet to have an oxygen-rich atmosphere without the presence of life. The first scenario is an Earth-like liquid water planet with oceans 50 times (or more) larger than on Earth. All of that water puts great pressure on the planet’s crust, shutting down the geological activity. This prevents things like the weather and the melting of rocks being two factors that cause oxygen to disappear from the atmosphere. The second scenario is the opposite: A dry desert world with 30% less water than Earth and they will solidify with a “steam atmosphere” for about a million years. This provides a large amount of oxygen in the atmosphere, as sunlight breaks down the molecules of water and hydrogen released into space. And because the planet’s solid desert surface cannot remove any oxygen, it stays in the atmosphere. The last way for a lifeless planet to have an oxygen-rich atmosphere is if the original planet had a higher ratio of carbon dioxide to water than the early Earth. In this case, the planet undergoes a greenhouse similar to what happened on Venus and becomes too hot for oceans to form in the first place. It is also too hot for volatiles to exist in the planet’s mantle, where they will isolate oxygen through chemical reactions. Instead, these volatiles are in the atmosphere, where they can no longer remove oxygen. The planets could have better life than the Earth Researchers have identified more than 20 planets outside the Solar System that have better conditions for life than Earth. Some of these planets have orbits stars that are probably even better than the Sun. A study led by Dirk Schulze-Makuch at Washington State University published in the journal Astrobiology details the features of planets with superlative potential, including is composed of planets that are older, slightly larger and warmer, and possibly more water than Earth. Life can also easily develop on planets moving around slower-changing stars that have longer lifespans than the Sun. The top 24 candidates for habitable planets are all located more than 100 light-years away from us, but Schulze-Makuch says this rescue could help future observations to focus properly, such as the James Webb space telescope, NASA’s LUVOIR space observatory and ESA’s PLATO space telescope. Researchers have selected planetary systems that are likely to have terrestrial planets moving around the parent star in the region of the habitable zone (an area that allows water to exist as a liquid on the planet’s surface) from Kepler’s archival data on transiting exoplanets. Our sun has a relatively short lifespan, less than 10 billion years, because it takes nearly 4 billion years for complex life to form on Earth, so many stars are similar to the Sun (types of G stars). ) may run out of fuel before life can develop. Along with monitoring the types of G stars, the researchers are also observing K-stellar systems, which are colder, smaller, and fainter than the Sun. Type K stars have lifespans that can last from 20 to 70 billion years. That allows the planets moving around it to grow older and allow life to have more time to have life as complex as Earth does today. However, for the planets to stay alive, the planets could not be too much as they could end geothermal activity and no longer have a protective magnetic field. Earth is about 4.5 billion years old today, but researchers think that the most ideal time for life on a planet is between the ages of 5 billion and 8 billion.

Photo of the Ingenuity Mars helicopter taken by NASA’s Preseverance spacecraft. Photo: NASA. Open a new door Ingenuity attached to the belly of the Perseverance probe landed together inside Mars’ 45 km wide Jezero crater on February 18. On April 3, a solar-powered helicopter was dropped from Perseverance’s belly. NASA is expected to make history on the Red Planet with its first self-powered flight powered by energy. “That is extremely important. Technological inventions will open a door to completely different tools. And for me, that’s very interesting. We still haven’t envisioned all the benefits of this new technology, ”said Thomas Zurbuchen, NASA’s Deputy Administrator. Ingenuity is considered a “technology show”. Because, the expected flight of this helicopter on Mars is designed simply to demonstrate the efficiency of the technology. Although there is an onboard camera to take pictures during the mission, it’s the only feature on the plane that is not directly related to Ingenuity’s take-off. “The speed of light is too slow for us to actually control it in real time,” said Mr. Zurbuchen. In addition, the team must find a way for the helicopter to fly over Mars in a challenging environment, with a very thin atmosphere. Obviously, flying on another planet is not easy for helicopters. This is an exciting moment in the history of spacecraft and technology. Many people questioned whether Ingenuity was equipped with any technology application to achieve such a feat. Scientists hope to use Ingenuity to explore in the future, according to Zurbuchen. Because, a small helicopter can “probe many places that we can not go to by plane”. The expert also explains that Mars has some interesting things. The crater walls and other destinations will be interesting to study up close, while astronauts won’t be able to explore. In the future, helicopters could be an important asset for both robot and human exploration on the Red Planet, Mr. Zurbuchen said. However, as mentioned before, Mr. Zurbuchen said, there are many applications to this technology that are yet to be developed. Science breakthrough The deployment of the Ingenuity helicopter flight plan on Mars aims to demonstrate that humans can fly in the extremely low density, reduced gravity and extreme temperatures of the red planet. In addition, the amount of sunlight the planet receives is only half that of Earth; At night temperatures down to -90 degrees C cause electronic components to crack and freeze if left unprotected. While a mission on Mars is not an easy task, NASA is confident that this small helicopter can overcome the challenge. However, the first flight will be at low altitude and take place shortly. Members of the mission group said, Ingenuity (weighing 1.8 kg) is expected to fly no more than 3 meters above the floor of the Jezero crater on Mars. The helicopter will stay high for 40 seconds or so. However, even such a modest flight time would be an achievement. Because, Mars’ atmosphere is only 1% thicker of Earth. Aircraft generate lift by pushing air. However, according to Project Director Ingenuity – MiMi Aung, of the NASA Jet Propulsion Laboratory (JPL) in Southern California, on Mars, there are fewer molecules to propel. That disadvantage outweighs the benefit that helicopters get from Mars’ weaker gravity. So Ingenuity has to behave a little differently from its predecessors on Earth. Specifically, Ingenuity propellers are made of carbon fiber, made for Mars. They are particularly large compared to the overall 48 cm high helicopter. Each wing extends 1.2 m. Those propellers will spin at about 2,500 rpm to bring Ingenuity off the ground. This is much faster than that required by a 4lb motor. Besides, Mars is also a place where the cold is “piercing”. Perseverance measured the Red Planet’s nighttime temperature to minus 117.4 degrees F (minus 83 degrees C) on the surface of Jezero. So Ingenuity has a fireplace so it won’t freeze. Currently, it takes more than 15 minutes for an order to be sent from the control agency on Earth to Mars. Real-time operation with the joystick is therefore not an option. Flight orders must be sent in advance. However, that doesn’t mean Ingenuity is going to be in trouble. This helicopter will be able to do many tasks on its own. For example, Ingenuity can analyze photos captured by the downward-facing camera. From there, locate it. The images will be in black and white. Ingenuity is also capable of 13-megapixel color photography. There are a series of complicated devices that are inserted into the “small body” of Ingenuity, although the helicopter does not carry any scientific tools. Cameras, electrical systems, avionics systems, and communications equipment for data transfer to Perseverance were all introduced into Ingenuity. In fact, the size of devices like objects has made it impossible for many helicopter missions on Mars. Ms. Aung and her colleagues tested Ingenity extensively on Earth before launching. Ingenuity used to have to fly in a special chamber at the JPL – which simulates the conditions of the Red Planet. Thanks to that, Ingenuity has been doing well on the Jezero crater since its separation from Perseverance. Therefore, the scientists expressed confidence in Ingenuity’s mission. If successful, Ingenuity will fly again – up to 5 times in about a month. Ingenuity helicopters pave the way for future space exploration.

Illustration. That could improve your chances of discovering organisms in distant worlds. How to find exoplanets Since 1999, a process of detecting exoplanets called the transit method has found thousands of other worlds by measuring the brightness of the stars that these planets orbit around. No one knows if these planets have any life, but if scientists observe the Earth using this method, they will probably detect signs of life. Once those signs are identified from Earth observations, experts can then find similar clues in the exoplanets. Scientists have recently described this approach as a mission called the Earth Transit Observer (ETO). This year, they presented this at the 52nd Moon and Planetary Science Conference. Most of the exoplanets we know of are found by transit, according to the US NASA Space Agency. Modern telescopes such as the Kepler Space Telescope and the Exoplanet Survey Satellite (TESS) can detect exoplanets when the path of a planet dims a star’s light overnight. slice. This is true even for stars thousands of light-years away. Scientists can estimate the magnitude of a planet based on the amount of light it is blocking and calculate the size of its orbit. The size and temperature of a host star as well as the distance between the planet and the star will provide additional clues as to whether exoplanets have life or not. The measure of transit can also hint at an exoplanet’s atmosphere. During a transit, a star’s light is filtered through atmospheric molecules. This could help researchers identify elements like oxygen and methane there. Such signs are often so small that astronomers need more transit observations to confirm the existence of these elements – according to a statement by the scientists. However, other factors on exoplanets and stars can affect the reading of molecules in the atmosphere. For example, planets change with the seasons, weather patterns and ocean currents. In addition, the activity of the Sun, such as the rise and fall of the solar wind, and the formation of solar storms also change. Any of these conditions can shape the behavior of the atmosphere, thus potentially affecting the proportion of molecules and elements in their atmosphere. Illustration. Finding “New Earth” Lead author Laura Mayorga of the planet-finding mission article in the Journal of Planetary Science says that, to understand those variables, “you need to know your stars as well as predict your planets. what do you look like ”. This can be a challenge when both the stars and the exoplanets are alien. “This is a very difficult problem,” says exoplanet astronomer at Johns Hopkins University’s Applied Physics Laboratory in Laurel Maryland (USA). Luckily, scientists already have all of those answers for a pair of inhabited planets and stars. That is our Earth and the Sun. For the ETO mission, a small satellite with a device capable of imaging near-violet to near-infrared light spectrum will observe the Earth as it passes in front of the Sun. The spectrophotometer will check for water and carbon dioxide markers as well as biological markers – oxygen and methane, ozone and methane. Besides, it is to point out the favorable conditions for life (of course, also to see if the signs are unique to Earth or not). The transit technique used in such an investigation would be similar to the technique used by the James Webb Space Telescope (JWST) to study some of the thousands of exoplanets, scientists say. know moving through their host stars ”. Since we all know the climate change on Earth and the patterns of the Sun’s activity, scientists can observe how they affect the reading of atmospheric molecules and then apply them to our observations. close to the “new Earth”. “The Solar System is the only place where we know all the answers. We can test our technique, point out limitations and make a connection between the results, ”said Mayorga in the statement -“ Then we can connect that with Unanswered observations from exoplanets ”. Scientists plan to submit the ETO proposal to NASA’s Astrophysical Pioneer Program in the fall of 2021.

Most planets in the universe are not suitable for us to live in. With the current environment in the planets, imagine how, if we humans lived there, the body would change. Mars Gravity is lower on Mars than on Earth and it is further away from the Sun, so if we live on Mars, we will see less sunlight. Mars also lacks a protective magnetic field due to its thin atmosphere, everything there, including humans, is exposed to radiation. Occasionally, strong winds create dust storms that fly across the planet, and dust continues to settle for months to come. So if you go to live on Mars, you may be taller, stronger body to compensate for the poor gravity. You will have big eyes for better visibility when the Sun is too far away. In addition, the main pigment in your body changes from melanin to carotenoids (carrots, tomatoes and oranges). So your skin is likely to be orange. Jupiter Living on the surface of Jupiter is challenging because the planet has no real surface. It is purely air. However, this does not mean it is just a giant cloud suspended in space. If you travel through its atmosphere to deeper parts, the gas will become dense until it turns into a liquid. In a nutshell, Jupiter is an ocean layer made up of hydrogen instead of water. With such high pressure, extreme temperatures and liquid environments, humans would have to mimic creatures that live in deep water. We would be like animals with small legs and hard shells to protect the body from Jupiter’s radiation. Saturn Saturn is also a giant cloud of hydrogen and helium, with no soil or no wind. However, inside it is much denser and much smaller than Jupiter. Its iconic belts are made of countless ice particles, so nothing can live on this planet. The Saturn rings are innumerable ice particles. Saturn’s weight is too small, so it can float in a bath if there is a tub large enough to hold. The only way to get around in the dense mist of Saturn is to hover around like a jellyfish. Your body will not have a skeleton so that it cannot be crushed by the pressure. Mercury Life on Mercury is extremely difficult. This tiny planet is closest to the Sun, so the sunlight here is seven times bigger than Earth, no sunscreen can resist. Mercury’s temperature is extremely extreme, around 430 ° C during the day and -180 ° C at night. The planet is also prone to meteor shower and earthquakes. There is no atmosphere here to breathe. How must we change to accommodate Mercury? Meat and bones can never withstand the harsh conditions here. So to live in Mercury, our bodies must be made of something similar to the refractory metal, for example, titanium. There’s no need for a respiratory system, so your pretty metal face won’t have a nose. And your eyes will be like a thick sunglasses to protect them from the sun’s light. Venus If there’s a place that’s harder to live than Mercury, it’s definitely Venus. The temperature here is a whopping 471 ° C. The atmosphere is extremely thick, creating a greenhouse effect. The planet’s surface is very dry, there are many natural disasters such as volcanic eruptions, hurricane winds and lightning. The pressure here is like you are 1 mile underwater, giving you constant headaches. Unfortunately, the only thing that can exist on Venus is bacteria. Venus corrode everything, even metal, making it impossible for human spacecraft to stop here. Venus’s atmosphere contains phosphine, which is toxic to any organism that breathes oxygen, but is very beneficial for bacterial growth. Uranus, Neptune Frozen, dark and plagued by strong winds, Uranus and Neptune are mostly made up of cold liquids – methane, water and ammonia. They do not have a solid surface, and their atmospheres slowly mix with the water around the cores of other planets. Gravity is stronger here than on Earth and puts more pressure on everything. With such a strong gravity, the human body living here would have to be shorter and muscular, muscular, and thicker in skin to resist the cold. And for the liquid environment here, the best form to live in is a cosmic dolphin or manatee, making it easier to navigate around the planet. The Pluto Pluto is the planet farthest from the Sun, covered with ice and snow. Gravity is extremely weak and the atmosphere is fragile. The sun seen from Pluto is just a dot on the horizon, like the Moon to Earth, so there won’t be much light. However, scientists believe that there may be ocean water below Pluto’s surface. If you live on Pluto, your body needs antifreeze, like some insects and fish. Low gravity causes muscles and bones to shrink, the space between the vertebrae expands and makes us taller. Human posture will also change as the spine is not doing too much. So you can be tall, thin, and somewhat spiderman with flexible limbs and a curved spine.

Many countries around the world are silently deploying plans to exploit Helium-3 from the Moon. Photo: Johnson Search Group Why does America want to return to the Moon after almost half a century? Why does China’s Hang Nga ship collect land on the Moon? Why Russia shook hands with China to build a Moon research station? And why has the Moon become the indispensable spot of great powers? Some say that it is to satisfy human curiosity, there are also opinions that it is to demonstrate the power of space science and technology of a nation. All is speculation, but the most important reason can be said that the Moon itself is an invaluable natural mine. As humanity is facing an energy crisis, governments around the world are looking for alternative sources of energy. High-tech companies have been exploiting non-fossil energy sources from the wind, the sun and the waves full of rivers. But that is not enough. Many countries have begun to look for new sources of energy outside the Earth. During resource exploration on the Moon, Chinese experts have discovered that there are more than 100 types of mineral resources on the Moon, not only have dozens of essential energy sources for the Earth, but also one The perfect energy source – Helium-3. Rare gas resources on the Moon. Photo: Sohu Scientists have found radioactive substances such as helium in soil on the Moon. After further analysis and determination, they found a large amount of Helium-3. Helium-3 is a valuable fuel source, because it can generate extremely high heat through fusion fusion without emitting almost no harmful radioactive neutrons. As such, fourth generation nuclear weapons using pure Helium-3 will generate little or no radioactive dust. Why does the Moon have so much Helium-3? During internal nuclear fusion, the Sun will generate a large amount of Helium-3, and Helium-3 will fall on surrounding planets after being blown by the solar wind. Because the Earth’s surface is covered by a thick atmosphere, the solar wind cannot reach the Earth’s surface, so the natural reserve of Helium-3 on Earth is very low. The Moon has almost no atmosphere, so the solar wind can directly reach the surface of the Moon, and a large amount of Helium-3 will be deposited on the surface of the Moon. The amount of Helium-3 on Earth is very small and Chinese scientists estimate that the reserve on Earth is only about 500 kg, difficult to meet the needs of mankind. The soil on the lunar surface contains at least 1 million tons of Helium-3, 2 million times more than the Earth. Experts calculated that 100 tons of Helium-3 could meet the world’s electricity generation needs in one year, and 1 million tons would be enough for 10,000 years! If Helium-3 in lunar soil could be developed and used, the construction of a nuclear power plant on the Moon could be done on the spot. But it’s not easy to separate Helium-3 from the Moon. First, it is necessary to heat the lunar soil to more than 700 degrees C to separate Helium-3. However, there is no oxygen on the Moon and is very difficult to burn. Moreover, to extract Helium-3, it must be based on the Moon, so far no country can do it. Since Helium-3 has significant energy and reserves advantages, the future Moon is more likely to become the “Persian Gulf” energy that major powers compete in the new century. In December 2020, the Chinese ship Hang Nga 5 returned safely after a mission to explore the Moon, bringing about 2kg of rock and soil from this planet to Earth. Under former President Trump, the 2020 NASA budget allocation plan shows that Washington wants to send people to the moon again before 2028. Former US Vice President Mike Pence also declared the United States to be the first power. first put a man on the moon in the 21st century. From unmanned exploration to manned landing on the Moon, and setting up lunar bases, China and the Western nations have consumed countless manpower and materials to not only satisfy scientific achievement. Behind that is endless resource ambition.

My name is Phung Quoc Huy Hoang, born in 1995 in Nha Trang, and currently live and work in Ho Chi Minh City. I have been pursuing printing 3D products for 5 years now. Previously, I studied restaurant management at the Industrial University, but decided to stop studying in year 2 because I felt this was not my passion. During my self-study, I knew a brother on social media who worked on clay. A monkey head statue made by this man based on the movie Planet of the Apes was so beautiful that I was constantly learning about clay making. Those were the first steps that brought me into the 3D printing industry. Since October 2018, I founded Craftech – a combination of craft (craft) and tech (technology) – with the desire to create printed products based on these elements. The 3D printing market in Vietnam started to emerge from 2017, and has grown quite strongly up to now. Before that, when making a machine part, the worker had to cut CNC with iron and steel. In terms of art, it also takes time to hire people to carve or make from clay. In addition, cost is one of the reasons 3D printing is increasingly popular. Before that, people often covered with earth or porous to create shape. Then comes the process of making silicone molds, pouring plastic and removing it like jelly. It is this mold making step that causes the cost to be high. With a total of 10 employees, we only perform some main stages such as mechanical design, art drawing, accounting … Processes such as CNC cutting, mold making … will be assigned to the unit. other for cost optimization. All drawing design operations will be done by computer simulation software. The 12 V printer consumes electricity about 3-4 million / month. When printing, the layers are overlapped and formatted under the control of the computer. These printers were bought by me at a local company with the price of over 10 million VND / 1 machine. The drawing is fed into the machine. I make some adjustments before printing starts. The material is melted before printing. Depending on the nozzle, the plastic wire is packed into rolls of different size. The ingredients are quite easy to buy in Vietnam. The glue part helps the sample stick to the 3D printing table. For large-sized products, we will assemble each part instead of printing the whole, because the printing size of the machine is only 40 cm2. Small printers also work in a similar way to large machines. This is a product of a small printer. We used to produce finished products with sizes as low as 2 cm. Some products are forced to print on a liquid machine because they require many small details that take weeks to complete. Not to mention, for products to achieve high perfection, manufacturers also need to coordinate many materials. Depending on the order, we will choose the appropriate production method. For example, direct printing would apply to event bookers requiring 10-20 products. With the requirements of mass production, quantity of tens of thousands, we have to make silicon molds or steel molds. This is a product we made for the dinosaur program organizer in Hai Phong. However, this project is manufactured from composite or silicon, not 3D printed. The biggest, most expensive 3D printed product we’ve ever made is a 5-meter bear delivered to a milk tea shop. In the workshop there are now more expensive projects, but made of silicon resin and molded composite, not 3D printing. A shipment is transported by us to customers in Phu Quoc. For bulky products, I have to pay a car rental fee. Up to now, the highest value project the company has ever implemented is a miniatures set at 1.8 billion dong. We do daily activities right at the factory. Currently the company is preparing projects for customers in the central region. I have surveyed but still have a lot of work in progress.

Bright Side brings together 10 rare creatures that are on the brink of extinction. Global mountain gorilla Currently the mountain gorilla has increased to about 1,063. They can only be found in protected forests. This is evidence that conservation efforts can bring a species back on the brink of extinction. However, illegal human hunting remains a major threat to the fauna of Bwindi-Sarambwe. Sao la The saola species was discovered in the Annamite forests of Vietnam. The main threat to saola is hunting activities and environmental climate impacts. That is why many conservation organizations have collaborated to create a safe environment for them in nature. Animal with dunnart bag This tiny creature can only be found on Australia’s Kangaroo Island, with an estimated population of less than 500. The widespread cleaning of the vegetation by humans has put the dunnart in a very dangerous situation. In addition, wildfires in Australia in 2019 and 2020 have burned 95% of the species. That is why a closed sanctuary was created to keep dunnart and other endangered species safe. Iberian lynx This rare species can only be found in the jungles of southwest Spain. From 1985 to 2001, their population decreased by 87%; So far, there are about 400 lynx in the wild. Their natural habitat continues to be destroyed by new highways and cut down trees. Black-footed ferret While people thought they were extinct, tiny creatures have proven to still exist. However, their population is rapidly declining due to disease and the loss of their natural habitat. Their total population is estimated at around 370 in the wild. Massive restoration efforts by many federal agencies and zoos have provided space for the weasels to survive. Gharial crocodile In 2010, only 15 crocodiles were found in the Gandak River in Bihar. That’s why in 2014, a conservation initiative freed 30 crocodiles from captivity and returned them to the river, and their population began to increase. Kakapo For the first time in 70 years, the kakapo population is increasing with about 213 species of birds existing. Only during the 2018-2019 breeding season, 71 young survived, which is a record number for this species. The recovery team tries to make sure the birds stay healthy and protected from infection. Their next goal is to find a good habitat for the birds as disease is their main threat. Canadian harbor seals Found in Quebec, this is the only species of its kind that can only survive in fresh water thanks to fish. To date, only more than 100 live in the area. The cause can be attributed to human hunting. Also, in many cases, seals get trapped in their gears and cannot free themselves. Leopard Amur This leopard has found a way to survive in the jungle in the Russian Far East. They live up to 15 years in the wild and more than 20 years in captivity. They have an amazing ability to run very fast and jump high. However, the loss of habitat and human activity has reduced their number to about 84 individuals. Vaquita dolphin This very rare marine mammal was discovered only in 1958. However, in recent years, vaquitas dolphins have been victims of illegal fishing activities. They are often trapped in fishing nets. That is why their population is only about 10 in the Gulf of Mexico. They can be found in shallow water but will quickly swim away if a boat approaches them.

Earth Day is launched by the United Nations, held on April 22 every year, to encourage movements to protect the environment around the world to prevent more frequent disasters. climate change and environmental destruction. April 22 this year will be the 51st Earth Day in the world. Since 1970 until now, the Foundation for Earth (Earthday.org) has been working with more than 75,000 partners in more than 190 countries to promote active action to protect planet Earth. In response to Earth Day 2021, from April 20 to 22, the Foundation for the Earth calls on the world to take action with world leaders to prevent the upcoming catastrophes of gas change. posterity and environmental destruction; together restore the Earth. “Restoring our Earth” is also the theme of Earth Day 2021 in the context of the world facing the Covid 19 pandemic and towards restoring normal life, economic recovery and restoration. Earth. Our Earth Restoration theme focuses on the emerging green technologies and natural processes that can restore the world’s ecosystems. In this way, the subject rejects the notion that mitigation or adaptation is the only way to address climate change. Rubbish at Lake Uru Uru, in Oruro, Bolivia, March 30, 2021. EPA photo. The global summit on climate was initiated by US President Biden On Earth Day this year, it is very special that the “Leaders Summit on Climate Change” will take place on April 22 and 23 and chaired by US President Joe Biden. This is one of the outstanding activities of the events celebrating Earth Day this year. The summit on climate is held in an online format with the participation of leaders from countries with major economies in the world. This summit also marks the 5-year anniversary of the signing of the Paris Agreement on climate change (December 12, 2015). On April 21, in a statement, a spokesman for China’s Ministry of Foreign Affairs said that Chinese President Xi Jinping will attend the summit on climate change organized by the US via online form. and there will be an important speech. President Biden has invited 40 world leaders including those who care about the environment along with leaders from the countries rated as the most polluting, such as China and India. This will be an opportunity for the new US president to commit his intention to fight climate change through a clean energy revolution for businesses and job creation for the people. The event will be streamed live for the public to follow. Many events are held for Earth Day Official poster of Earth Day 2021. Source: earthday.org. There will be hundreds of events held around the world during the largest event on the planet. The Organization for the Earth alone will organize “Three Days of Climate Change”, a three-day conference with many seminars and presentations. The event started on April 20 with the Global Youth Summit hosted by Earth Uprising. This global youth summit includes seminars, speeches, discussions and messages with the participation of prominent climate activists such as Greta Thunberg, Alexandria Villasenõr and Licypriya Kangujam. On the evening of April 20, the Hip Hop Caucus organization and its partners organized an online summit “We Shall Breathe”. This digital event will look at climate and environmental justice and equity, the links of the climate crisis to pollution, poverty, and racism. and pandemic. On April 21, the Multilingual Online Summit that spanned various time zones with the participation of prominent activists from the continents, focused on the important role of climate change educators and why we need climate change education right now. The conference is hosted by Education International (Education International) with the theme Education for the Earth. In parallel with the aforementioned global climate summit, the For the Earth Organization will hold seminars, special discussion groups to focus on the topic “Restoring Our Earth”, in That will cover natural processes, green technologies and innovative thinking that can restore the world’s ecosystems. Selected topics include: Understanding of climate and environment; Climate recovery technology; Efforts to reforest forests; Regenerative agriculture; Equity and justice for the environment; Science and civic education about the Earth and the environment; Clean up the world and more.

Through #ConnectedByEarth, NASA says, aggregated images of various regions, humans and other creatures shared by people create a beautiful picture of the many pieces of the puzzle that are connected to each other in our world.

“This work makes it possible for us to understand part of the study,” said Benjamin Hess, a graduate student in the Department of Earth Sciences and Planetary Science at Yale University and the first author of the study. form life on Earth, and possibly extend to study of planets – life could be forming on those planets in a similar way “. The origin of life also commonly known as the process of life generation (abiogenesis) is a term for the different theories about the formation and development of life on Earth. Of these theories, the most popular up to now are the scientific theories that say: this is the natural process by which life arises from non-living matter, from inorganic substances into single organic compounds. simplified, then evolved into today’s world. As we all know, phosphorus is an essential component of life on Earth. Even looking for extraterrestrial life in space, scientists will look for signs of phosphorus. However, billions of years ago, phosphorus was trapped in insoluble minerals and was difficult to escape and exert its effects. Therefore. This issue has been of interest to scientists for many years, who want to know how phosphorus is converted into an easier to use form, thereby promoting life-generating processes. Researchers suggest that the phosphorus that helps create life on Earth may come from schreibersite, a rare but very common mineral in meteorites. When lightning strikes soil or sand (derived from meteorites) on the ground, it can instantly melt and then solidify to form natural glass – fulgurite (also known as clayey rock. ). These meteors can be submerged, meaning that in the presence of water, the phosphorus in this mineral can be dissolved outward and potentially become part of a chemical reaction. Although the details of life’s formation on Earth are still unknown, the popular scientific hypothesis is that the transition from non-living entities to living entities is not an event. single, which is an increasingly complex process involving molecular self-replication, self-assembly, autogenesis and the appearance of cell membranes. Although the occurrence of the origin of life is not controversial among scientists, there is no single accepted model for the origin of life. Initially many scientists agreed with this idea, but through intensive research and statistics, they found that from 3.5 to 4.5 billion years before life on Earth was born. The number of meteors on our planet is not enough to be life-boosting factors. In the new study, Hess et al. Proposed that phosphorus on Earth could come from lightning strikes. They believe that this is more likely than that of elemental phosphorus coming from meteorites, because compared to asteroid collisions, the number of lightning strikes Earth each year is relatively stable. “This makes lightning an important way to study the origin of life,” Hess said. The team also used computer modeling to estimate how many lightning strikes occurred on Earth during the critical period in the beginning of life. They found that there could be between 1 billion and 5 billion lightning strikes the Earth each year, and 100 thousand to 1 billion of them falling on the Earth’s surface. Earth remains the only place in the universe known to life, and fossil evidence from Earth facilitates most studies of the origin of life. The age of the Earth is about 4.54 billion years, the earliest irrefutable evidence of life on Earth dates back at least 3.5 billion years ago, and possibly as early as the Ancient Pre-Tai era ( 3.6 to 4.0 billion years ago), after the geological crust began to harden after the molten Hadean Eon. In May 2017, scientists found possible evidence of early terrestrial life in the 3.48 billion year old geyserite and other related mineral deposits (often found around water springs). hot and geysers) discovered in Pilbara Craton, Western Australia. According to the study’s estimates, the number of lightning strikes on Earth could reach 10 ^ 17 to 10 ^ 18 in a billion years. Researchers suggest that under the impact of too many lightning strikes, after 1 billion years, ores formed by lightning strike the ground can release phosphorus that can participate in chemical reactions in the presence of water. In other words, it was lightning in this period that produced enough phosphorus to explain the existence of phosphorus at the origin of life on Earth.

In a new study published in the journal Acta Astronautica, scientists said, in the future, a dangerous asteroid will plunge itself and collide with Earth. Relatively, an asteroid does not need to be too large to cause severe destruction. One of the simulations in this study is the asteroid 300 meters (1,000 feet) in diameter, the size of six Olympic swimming pools. This is not a large asteroid, but it would still destroy an area of ​​a large city with just the initial impact. An asteroid of this size is possible; as of October 2020, scientists have discovered 9,336 near-Earth object / asteroids (NEO / NEA) that are larger than 140 meters in diameter. Among them, scientists have classified 2,122 as potentially hazardous objects (PHO). So the risks here are not astronomically low – they are more likely to fall to Earth. Scientists say NASA has found that nuclear weapons are “10 to 100 times more effective” in moving asteroids out of a collision course with Earth than alternatives. Non-nuclear, thanks to the much higher energy of fission materials than conventional materials. This energy will apply the asteroid / asteroid an appropriate force to push the asteroids / meteors closer to Earth out of their original orbit. Detonating nuclear weapons to prevent an asteroid / asteroid plunge into Earth is considered optimal and feasible; Source: popularmechanics.com There are two ways to “treat” an asteroid / meteor – disruption or deflection it. In their research, the scientists ran computer simulations to see how it could dislodge the asteroid 300 meters from its flight path toward Earth. Shattering was Armageddon’s solution – hitting the asteroid directly to shatter it into much less damaging pieces. The other way – deflector, is a more “elegant” solution, according to the researchers. This only involves redirecting the entire asteroid so that it doesn’t hit Earth, eliminating the remaining variable left behind by a broken asteroid – debris. When detonating a nucleus near an asteroid, what happens is quite simple – detonating a nuclear device above an asteroid irradiates a certain surface area. Material near the surface melted almost immediately. This small amount of superheated matter then expands out of the asteroid as “blown”, creating a pressure wave in the remaining asteroid. A rocket-like emission pulse is transmitted and the asteroid’s initial velocity is altered, deflecting the asteroid. Nuclear detonation in simulations to change the intensity of its released neutron energy, the scientists found, up to 70% of the deflector action. So if we do this in the real world, the nuclear device will liquefy part of the asteroid’s surface, creating a backlash that alters the asteroid’s orbit. It must be a nuclear device that releases neutrons, not an X-ray emitter, to be as efficient as possible, the researchers said. And while we hope we never have to use those, it’s definitely better if we know in advance that we can.

People in the Eastern Hemisphere can observe Apophis without binoculars by 2029. Exclude from the risk Asteroid 99942 Apophis was discovered in 2004. Apophis was quickly identified as one of the most dangerous asteroids that can impact Earth. However, that impact rating changed as astronomers tracked Apophis and its orbit. Now, results from a new radar observation campaign combined with accurate orbital analysis have helped astronomers conclude that Apophis poses no risk of impacting our planet in the least. at most a century. About 340 meters across, Apophis is quickly known to be an asteroid that could pose a serious threat to Earth. At that time, astronomers predicted that this asteroid would come close to Earth by 2029. Thanks to additional observations of a near-Earth object (NEO), the risk of impact by 2029 has since been eliminated. The scientists then also ruled out the potential impact risk posed by another close approach in 2036. However, a small chance of impact by 2068 is thought to still exist. When Apophis moved away from Earth on March 5, astronomers had an opportunity to use the radar observations vigorously. As a result, it helps refine estimates of the orbits of asteroids around the Sun with extremely high accuracy. Thus, scientists can confidently eliminate all risks of collision by 2068 and much later. “An impact in 2068 is no longer in NASA,” said Davide Farnocchia of the Center for Near-Earth Objects Research (CNEOS) managed by NASA’s Jet Propulsion Laboratory (JPL) in Southern California (USA). possibilities could happen again. Our calculations do not show any risk of impact for at least the next 100 years ”. Mr. Farnocchia mentioned the Sentry Risk Impact Table. Maintained by CNEOS, this table holds information about some asteroids whose orbits bring them so close to Earth that the impact cannot be ruled out. With recent findings, the Risk Impact Table no longer includes Apophis. Optical telescopes and ground radars help characterize every orbit of objects near Earth. As a result, scientists can improve long-term risk assessment. CNEOS calculated a high-precision orbit to support NASA’s Planetary Defense Coordination Office. Apophis is no longer a threat to Earth. Opportunity to “follow” Apophis Apophis is the size of three soccer fields, weighing 27 million tons. If it collided with Earth, it would cause an explosion that was equivalent to 880 million tons of TNT. This power could destroy a country of mid-size. Its impact with the Earth will be 65,000 times stronger than the atomic bomb that once fell on the city of Hiroshima, Japan. The impact hole it left could be 518m deep. To achieve new Apophis calculations, astronomers used 70 m radio antennas at the Deep Space Network’s Goldstone Deep Space Communications Complex near Barstow, California. As a result, they were able to accurately track Apophis’ movements. “Apophis used to be close to Earth, but it still has nearly 10.6 million miles (17 million km) to go. Despite this, we were able to obtain extremely accurate information about the distance of Apophis with an accuracy of about 150 m. This campaign helps us eliminate the impact of risk and a great scientific opportunity, ”said JPL scientist Marina Brozovic – who led the radar campaign. Goldstone also partnered with the 100-meter-long Green Bank Telescope in West Virginia to allow Apophis to be photographed. Goldstone transmits while Green Bank receives – experiment that doubles the strength of the received signal. Although the Apophis radar image appears in pixels, the image has a resolution of 38.75 m per pixel. This is a remarkable resolution, considering whether the asteroid is 17 million kilometers away, or about 44 times the Earth-Moon distance. As the radar team analyzes more data, they also hope to learn more about the asteroid’s shape. Previous radar observations have shown that Apophis has a “double layer”, or peanut-like appearance. This is a relatively common shape among asteroids near Earth that are greater than 660 feet (200 m) in diameter. Astronomers are also working to better understand Apophis’ rotation speed and the asteroid axis orbit. On April 13, 2029, the Apophis asteroids will cross less than 20 thousand miles (32 thousand kilometers) from the surface to closer to Earth than the distance of geotechnical asynchronous satellites. On that close 2029 approach, terrestrial observers in the Eastern hemisphere could witness Apophis without the aid of a telescope or binoculars. This is also an unprecedented opportunity for astronomers to get a close-up look at a monument in the Solar System. In particular, now, Apophis is just a scientific curiosity, instead of a danger to our planet. “When I first started learning about asteroids after college, Apophis was a malformed child among dangerous asteroids,” said Mr. Farnocchia. There is a certain sense of satisfaction to see it removed from the list of risks. We are looking forward to knowledge that we can explore in its up-close by 2029 ”.

The entire NASA Jet Propulsion Laboratory (JPL) in the state of California burst out loud, clapping. After more than 10 days of delay, the Ingenuity helicopter weighing only 1.8 kg, worth $ 85 million of NASA, took off successfully on Mars. This victory is likened to NASA as the living moment of the Wright brothers (USA) who successfully made the first flight on Earth in 1903. NASA’s Jet Propulsion Laboratory (JPL) tweeted immediately after Ingenuity’s success: “Perseverance has brought us to Mars. And Ingenuity takes us higher.” “. NASA’s Mission Control Room at (JPL) received a 14-minute delay in success signal because of a distance of 289 million kilometers from Mars.

Photo: Reuters “Now, 118 years after the Wright brothers successfully made the first flight on our planet in the 20th century, the Ingenuity helicopter has succeeded in performing this amazing feat in the world. another – the Red Planet – in the 21st century “- NASA Deputy Science Director Thomas Zurbuchen said. At a distance of 289 million km (from Earth to Mars), the Ingenuity Mars helicopter has done a miracle, unprecedented in history: Automatically refuel from the Sun, automatically fly to a maximum prescribed height of 3 meters and maintain that altitude stable for 30 seconds, then a gentle landing on the surface of the Red Planet. The whole process took 39.1 seconds. 39.1 seconds is only two-thirds of the time of a minute. The time is extremely short but is a wonderful fruit for the efforts of thousands of minds to contribute to Mars Mission 2020 of NASA. It took NASA nearly a decade to prepare for this feat. SURVIVAL WITH SUCKS Dr. Daniel Brown, an astronomy expert at Nottingham Trent University (UK), described sending something flying to Mars as a ‘staggering feat’. The biggest challenge of the Ingenuity engineering team is the flying environment on Mars: – First money. So far, no one (human) has set foot on Mars. All scientists know is simulate that environment through data and images transmitted by NASA’s self-propelled explorer ship back to Earth. – Second, the Mars environment is known for its harshness: The difference in temperature between day and night can “kill” human machines, in particular, Ingenuity helicopters are too small, too light (this is required technical conditions for test flight). Not to mention, the Red Planet does not have a magnetic field, the gravity one third that of Earth; and the atmosphere is extremely thin, only 1% of the pressure on the surface of our planet.

Therefore, the blades of Ingenuity reach 2,500 rpm. Each propeller on the Ingenuity is made of a 57-gram composite material that powers a chopper body the size of a tissue box! OPEN THE WAY TO DISCOVER THE NEW SKY To further mark the link between the Martian Ingenuity helicopter and the Wright brothers ‘maiden flight, NASA confirmed it had named the first Mars airport (where the Ingenuity helicopter took off) as’ Wright Brothers. Field ‘. “We don’t know exactly where Ingenuity will lead us, but today’s results show that the sky – at least on Mars – may not be the limit,” said NASA Administrator Steve Jurczyk. . Just as the Wright Brothers’ flight ushered in human exploration of the sky on Earth, Ingenuity’s mission has sparked a new wave of exciting projects, poised to take the discovery of distant world to a new level. In 2027, NASA plans to launch Dragonfly mission his highly anticipated, in which a helicopter will fly over the sky of Saturn’s moon Titan. Other missions to explore distant atmospheres – such as Venus’s cloud survey mission – may soon emerge. THE MISSION OF INGENUITY NOT STOP HERE … The NASA team plans to have Ingenuity more test flights in the next few days, with up to five bolder flights over the next 30 days assuming each is successful.

“When the sky becomes low, the eagle’s flight does not have enough height…” In 2020, the new crown epidemic has brought shocks and changes that everyone can feel to the world. Facing the tremendous changes in the real world, the poet Ji Di Majia concentrated on completing a long poem of more than 500 lines, “The Splitting Planet”. In this poem, Ji Di Majia once again exerted his ability to control long poems, using his keen observation and profound thinking of the world reality.

Because of his outstanding performance in thought and art, on the morning of April 16th, at the “China Lizhuang·October Literary Award” award ceremony, “Split Planet” was awarded the 17th (2020) October Literary Award Special award. The award ceremony read: “The Split Planet” is about human beings, the planet we live on, and the unknown destiny of Huang Zhong Dalu. It uses the global virus epidemic as the basis, visions the past and the present, and deeply tortures mankind. The many crises of its own destiny, its existence and development, and a thought-provoking question and answer. “Splitting Planet” is a poem of sad thoughts, a poem of self-soul, and a poem of warning from oracles. It brings ancient peoples The fusion of epics and myths with magma-like passion has brought a brand new scene to Chinese poetry in the new century.”

Standing on the podium, Ji Di Majia briefly reviewed the time background and original intention of his writing and reading this poem, “Although mankind will encounter various disasters, I believe that through love and confidence, the destiny of mankind will definitely change. It’s better.”

In “Cracked Planet”, we can see that the poet’s sight scanning is so vast: from the Euphrates and Ganges, to the Mississippi and the Yellow River, from the Arabian desert to the blue Mediterranean. We can see that the poet’s spiritual world is so broad: war and peace, politics and philosophy, religion and civilization, rights and freedom. We can see that the poet’s deep affection for the natural world, the image of leopards, tigers, migratory birds, orangutans, etc., flashes more and more. Words such as sky, fire and ocean appear frequently. Benjamin, Zweig, Adorno, the faces of wise cultural philosophers in history, emerge one by one in the entire poem. More importantly, this poem allows us to see a mature and outstanding poet who has made his own positive response to his own time through artistic methods and works. The cover news reporter interviewed Ji Di Majia. Around this long poem, the poet talked about his own creative mind, the formation of the poetry style, the relationship between art and the times, etc., and talked freely about his own views and opinions.

It is difficult to write such a long poem and keep it in a good state throughout. Speaking of the experience and experience of writing long poems, Ji Di Majia mentioned in an interview with a cover news reporter, “The difficulty in writing long poems with modern meaning is not how to write long poems. It is how to maintain the inner aura of poems. Luck is not interrupted. Of course, the structure of a long poem is important at all times. But despite this, the core of its structure is what I call “Qi Luck”, which will run through and cannot be interrupted at will, otherwise the long poem It will become a composite of countless short poems. I think the biggest challenge in writing any long poem is not how to write it, but how to keep this kind of “qi luck” always in a strong state. Of course, this state and Rhythm does not always stay on one frequency, it fluctuates up and down, sometimes even peaceful and quiet.”

Illustration of lightning hitting Earth 4 billion years ago.

However, according to geologists, lightning strikes are just as important as meteorites to create perfect conditions for life on Earth.

Scientists believe that the minimum amount of minerals present on early Earth was caused by billions of lightning strikes.

Detect important minerals

A study published in Nature Communications led by scientist Benjamin Hess of the School of Earth and Environment, at the University of Leeds (UK) looked at the possibility that lightning could contribute to life.

The scientists found that life could develop on Earth-like planets through the same mechanism at any time if the atmospheric conditions were right.

Hess et al. Studied an exceptionally large and primitive fulgurite sample. This is a rock created when lightning strikes the ground. This model was formed when lightning struck a house in Glen Ellyn, Illinois (USA) in 2016 and donated to the Geology department at the nearby Wheaton College.

The Leeds researchers were initially interested in how fulgurite was formed, but were later intrigued when they discovered that there was an unusual amount of a phosphorus mineral called schreibersite in the sample at Glen Ellyn.

Phosphorus is essential for life and plays an important role in all life processes from movement to growth and reproduction. Phosphorus has been present on Earth since infancy and is in minerals that cannot be dissolved in water, however, schreibersite can.

Mr. Hess is a graduate student at Yale University, Connecticut (USA), said, “Many people believe that life on Earth originates from shallow surface waters according to the famous” small warm pond “concept of the house. Darwin Science ”.

“Most models of how life might form on the Earth’s surface show that meteors carry small amounts of schreibersite.

Our research found a relatively large amount of shreibersite in fulgurite “- he said -” Lightning hits the Earth regularly, which proves that phosphorus is necessary for the origin of life on the Earth’s surface not only. rely on asteroid collisions.

Perhaps more importantly, this also means that the formation of life on another Earth could still take place long after meteoric collisions became rare.

The phosphorus minerals produced by the lightning bolts exceeded those from meteorites when Earth was about 3.5 billion years old (the age of the earliest known microscopic fossils), the team estimated. That underscores the importance of lightning to life on Earth.

Furthermore, lightning bolts are much less destructive than meteorite collisions, meaning they are less likely to interfere with fragile evolutionary paths in which life can
develope.

The fulgurite was excavated in Glen Ellyn, Illinois (USA).

The role of lightning quantity

Lightning is also a topic of interest to scientists when thinking about life on Earth in the early days because it leads to the production of gases like nitrous oxide that played a role in the origin of life. .

Hess and his other researchers used this existing research to investigate and review the rate of lightning strikes on early Earth. Today, we have 560 million lightning strikes a year.

Meanwhile, early Earth, this number was from 1 to 5 billion per year, of which 100 million to 1 billion lightning strikes the ground. Over a billion years, lightning strikes can reach 1 trillion and generate a lot of phosphorus.

In the early days, lightning struck more on Earth because there was more carbon dioxide in the atmosphere. Carbon dioxide contributes to global temperatures and the higher the temperature, the more intense and frequent the storms are, Hess said.

“Carbon dioxide levels soared on Earth early after a Mars-sized object crashed into Earth and created the Moon 4.5 billion years ago. This also releases a lot of gas from inside the Earth, like carbon dioxide, which then gets trapped in the Earth’s atmosphere and leads to more lightning, ”explained Hess.

The fulgurite fragment is found in Glen Ellyn, Illinois (USA).

Expert review

Dr., Associate Professor of Geochemistry Jason Harvey and Professor of Geology and Structural Construction Sandra Piazolo at Leeds University’s School of Earth and Environment advised Mr. Hess on the above research project.

“The initial meteor bombardment was a one-time event in the Solar System,” said Dr. Harvey. When the planets reach their mass, the additional distribution of phosphorus from the meteorites becomes negligible.

On the other hand, lightning is not a one-off event, the elements necessary for the formation of life can thus be transferred to the surface of a planet. This means that life can appear on Earth-like planets at any given time.

Meanwhile, Professor Piazolo said: “The above interesting research opens the door to some future paths when searching for and analyzing in depth new fulgurite in the early Earth-like environment, analyzing The effect of heating on other minerals is to realize similar characteristics.

There is also a further analysis of this particularly well preserved fulgurite to determine the extent of the physical and chemical processes within it ”.

“All these studies will help to improve our understanding of the importance of fulgurite in changing the chemical environment of the Earth over time” – Professor Piazolo added.

Bear eat ants for a body length of 150cm but has a tongue up to 60cm long. True to its name, the bear eats ants, this bear eats ants, termites and a long, sticky tongue with small spines is a very effective “tool” in catching prey. With the speed of releasing and retracting the tongue up to 150 times / minute, ant-eating bears can catch up to 30,000 termites per day.

Ants’ stomachs have a special structure that can crush large numbers of ants and termites, helping to facilitate digestion. This stomach produces formic acid instead of the hydrochloric acid commonly found in other mammals.

Bear eat ants have poor eyesight, but the ability to smell very sharp, 40 times more than humans. They use their noses to find food. The body temperature of the ant-eating bear was 32.7 ° C, which is lower than that of other placenta, mammals. If living in the wild, ant-eating bears can last 15 years and 25 years if kept in captivity.

The bear eats pregnant ants for 190 days and gives birth to only one baby per litter. A bear that eats ants will stay with her mother for two years until the bear that eats the ant is pregnant again. In the first year of life, the bear eats the mother ants and will carry the baby on her back.

Bats suck honey

The honey-sucking bat is one of the famous bats for its long tongue. Its long tongue when retracted was hidden in the chest.

A species of bat with a tube-shaped mouth specializing in nectar absorption, or known as Anoura fistulata has the longest tongue of any mammal on the planet. The tongue of this exotic animal is about 8.5 cm long, 1.5 times its body length. According to Iflscience, this particular species of bat broke the record for the first bat species in Ecuado decades ago.

Now, according to the Association for the Conservation of Wildlife, a strange species of bat has been found for the first time in Bolivia’s Madidi National Park. This unusual tongue allows them to easily suck nectar from the ends of a funnel-shaped flower. This is also an effective way to pollinate this elongated flower.

In fact, with a tongue almost twice the length of its body, there is no animal in the natural world that has “overtaken” the long ratio of the tongue to the body of this bats.

Pangolin

Pangolins have a tongue up to 40cm long with a lot of sticky drool to easily catch prey. Its tongue stalks deep in the abdomen. This animal has no feathers, only a hard scaly covering its body, and also has no teeth. The pangolin’s food is mainly ants and termites.

British naturalist David Attenborough chose the Sunda pangolin (a species of pangolin distributed throughout Southeast Asia) as one of the 10 species he wants to rescue from the most endangered.

So what makes pangolins so special? Here are facts to help us understand more about one of the most endangered species on Earth.

Currently in the world there are about 8 species of pangolin in existence, and some species have been extinct during evolution over the past 80 million years. Four of them live in Asia: China, Malaysia, India and Palawan Island (Philippines), while the remaining 4 species are distributed in Africa.

When fully stretched, the pangolin’s tongue can be up to 40cm long and the base of the tongue is deep in the chest cavity. The pangolins use their sticky tongues to catch insects. Because pangolins have no teeth, they crush and digest food with stones in the stomach.

The scales of pangolins are mainly composed of keratin, similar to human nails, rhino horn or bird nails … The horn scales account for 20% of the weight of this animal. The very hard scales can protect pangolins from predators. However, in traditional Chinese medicine, people dry and roast pangolin scales because they believe they can cure polio, stimulate lactation for women … For that reason, the price of pangolin scales on the black market amounted to more than 3,000 USD / kg.

Earth has been 4 billion years old since its birth in the universe. In the long history of the Earth, the stars, planets, satellites, asteroids in the universe along with the Earth have all had a fixed or uncertain mode of action. The formation of the Solar System, the Moon, asteroids crashing into the Earth, comets … prove that claim.

As the development of human civilization took shape on Earth, we began to explore the mysteries of the universe and our own planet.

Humans have discovered countless impact craters on Earth formed by the “falling stars” that once crashed into the Earth. These “falling stars” are then referred to as “meteorites / asteroids”, and the traces they leave on Earth are known as “meteorite craters” or impact craters.

It can be said that the crater is a symbol and evidence of the intersection of cosmic objects and the Earth. Not only that, some scientists who support the “exogenous” theory even believe that the water and energy necessary for life on Earth today are due to the impact of meteorites and comets.

Although this is not supported by strong evidence, the craters are still very valuable to scientists studying celestial celestial bodies. It is of great significance for the study of the formation and evolution of the Earth, the change in climate, the environment and animals in ancient times, the role of biological processes and mineralization.

Today, many meteorite holes have been discovered, through studying them, people have discovered many unknown secrets from ancient times as well as unique minerals created when Huge asteroid collided with the Earth.

THE LARGEST THIEN THIEN THE PLANET

According to the report of the Earth Impact Database released in 2016, worldwide there are about 190 impact craters detected so far. And the planet’s largest, oldest and most severely eroded asteroid crater is Vredefort Crater in South Africa.

The Vredefort asteroid crater is a crater that has existed on Earth for 2 billion years – it is the result of a meteor’s shock impact with the Earth at speeds right between 40,000 and 250,000 km / h. The diameter of the Vredefort Crater exceeds 300 km, making it the largest and oldest meteorite crater in the world (second after the Yarrabubba crater in Australia (2,229 billion years old), NASA updates for 2020.

The Vredefort meteorite hole in South Africa.

This huge meteorite hole is located in the Free State province, South Africa. Because the crater is so large, local people do not realize it is the “legacy” from the “meeting” of the Earth and meteorites. However, its enormous size has attracted scientists and geologists from all over the world.

In 2005, the United Nations decided to include the Vredefort impact pit on the list of World Heritage Sites in need of protection.

LOOK AT THE PAST – FORWARD TO THE FUTURE

Talking about the crater / meteorite hole, many people do not know the Chicxulub (Yucatán peninsula in Mexico), 150 km in diameter, occurred about 65 million years ago.

Many scientists believe that perhaps the extinction of a generation of dinosaurs on Earth at that time was related to the climate change due to the impact of this meteorite.

Likewise, as the world’s largest crater, the formation of the Vredefort Crater should have had a serious impact on Earth’s climate and biological evolution. We just haven’t figured out exactly what it has affected and how it affects it.

Before that, the United Nations formed a scientific research group, based in South Africa, and conducted scientific research in the Vredefort crater for seven years. In the end it was asserted that the meteorite’s destructive power plunged into Vredefort enough to change the climate and the structure of the African plate. Scientists are continuing to study the long-term effects from Vredefort’s earlier.

What is different from Vredefort’s other meteorite craters in the world is that it has grown from what should have been abandoned into a city complete with hundreds of thousands of inhabitants, and generations of people have been in This huge crater is like a peaceful paradise.

Scientists said, meteorites that plunged into the Earth may leave large “scars” for Earth on the bottom of the deep sea. Because the asteroid craters we’ve found so far are all above ground.

Due to the very large and deep seabed area, scientists currently do not have enough technology to conduct detailed investigations. Therefore, the impact crater on the sea floor remains an unsolved mystery in the scientific world. If you want to research, you must go through a long process of discovery by scientists, and this will also be the direction that scientists need to strive for in the future.
