Speculation about the mysterious origin of the aurora has been around for a long time. But until now, unsubstantiated inferences have been clearly proven. The mystery has been revealed According to a new study published in the journal Nature, a team of physicists from the University of Iowa has finally demonstrated that the aurora is “generated by strong electromagnetic waves during geomagnetic storms.” The Northern Lights appear over a waterfall in Iceland.

Research shows that these phenomena are known as Alfven waves, which launch electrons to Earth, causing the particles to produce a stream of light that scientists call the aurora borealis. “The measurements reveal that the small number of electrons undergo ‘resonant acceleration’ by the electric field of the Alfven wave, similar to a surfer catching a wave and continuing to accelerate while surfing with the wave,” said Deputy Professor Greg Howes, of the Department of Physics and Astronomy at the University of Iowa, is also a co-author of the study, said. The idea that electrons “surf” on an electromagnetic field is a hypothesis first introduced in 1946 by Russian physicist Lev Landau. The theory is named after the physicist who called it Landau damping. After more than 70 years, the Landau damping theory has been proven. Aurora re-creation After decades of research, scientists have understood how the aurora is produced, but only now have they been able to simulate these colorful bands of light. For the first time, artificial auroras have been recreated in the lab using large plasma physics equipment (LPD) at UCLA’s Basic Plasma Science Facility (BaPSF).

According to the CNN , the scientists used a 20-meter-long room to reconstruct the Earth’s magnetic field using powerful magnetic coils on UCLA’s LPD instrument. Inside the room, the scientists created a plasma environment similar to what exists in near-Earth space. “Using a specially designed antenna, we project Alfven waves down the machine, just like when you quickly shake a water hose up and down and watch the waves move along the hose,” Mr Howes said. When they began to experience electrons “surfing” along the wave, they used other specialized instruments to assess how the electrons received energy from the wave. “Although the experiment did not reproduce the range of multicolored light in the sky, our measurements in the laboratory matched predictions from computer simulations and mathematical calculations, demonstrating that the Electrons surfing on Alfven waves can accelerate up to 72 million km / h and create aurora,” Mr Howes said. Study co-author Craig Kletzing added that these experiments allow them to make key measurements to prove the spatial and hypothetical measurements that actually explain how the aurora is produced. The aurora was taken in Alaska. Photo: Getty Images. Many space scientists are also excited by this new news. “I feel so excited! There are very few laboratory experiments that can prove hypotheses and models related to the space environment. Because space is so vast that it can’t be simulated in a lab,” said Patrick Koehn, a scientist in NASA’s Helicopter Physics Division. According to Koehn, understanding the acceleration mechanism of the electrons that produce the aurora will be useful for many future studies. Long road ahead Currently, the theory of how the aurora is generated has been proven, but there is still a long way to go to predict the strength of each upcoming storm. “Predicting the strength of a particular geomagnetic storm, based on observations of the Sun and measurements from spacecraft between the Earth and the Sun, remains a difficult unsolved problem.” Mr Howes said. Howes said they have established the bond of electrons surfing on Alfven waves about more than 16,000 km above the Earth’s surface. And now, they must learn to predict the strength of those Alfven waves using spaceship observatories.

A new nail trend appeared in Korea, called “Aurora” (aurora). According to GirlStyle, since Jennie – a member of BlackPink group – promoted this fashion, young people have started following the trend. Photo: Jennierubyjane, FreeDom Design. When in the dark, this nail design can show colorful light, like nature’s aurora. In addition to the basic model, many kimchi artists also make different variations to serve young customers. Photo: Naihara bemik. Classic Aurora is the model Jennie promotes. The color of the nails changes according to the refraction of light so they will not look dull and monotonous. Vogue This type of comment will be of interest to many girls because it’s simple and can be done by yourself. Image: Oneureun . More illustrations: If you want your nails to be less monotonous, you can ask the artist to add flat shapes like butterfly wings or your favorite cartoon characters. With the vibrant aurora colors in the background, the cheerfulness is enhanced. This is the ideal choice for bubbly girls. Image: Tetty, Ssomnail. Fuzzy version: In case the Aurora nails are too eye-catching, consider the matte effect. This part will be adjusted to a funny shape as required such as round, square or heart. Image: Tetty. Three-dimensional decoration Give your nails more depth. However, the disadvantage of this type is that it feels heavy and easily entangled when operating.

As noted by Fox News, NASA’s rocket launch window opened at 20:04 and the rocket launched at 20:36 on the same day. About 10 minutes after launch, the Black Brant XII rocket ejected barium vapor at an altitude of about 350-400km above the Atlantic Ocean, just north of Bermuda and about 870-900km from Wallops. The barium vapor from the NASA rocket is not harmful to the environment and has formed two blue-violet clouds that can be seen across the East Coast for about 30 seconds. However, clouds prevented the launch from being viewed with the naked eye. “This is the last date NASA intends to authorize a rocket launch from Wallops. The vocal rocket was originally scheduled to launch on May 8 but has been postponed several times a week,” Fox News wrote and reported. For further information, the Black Brant XII rocket launched during NASA’s KiNet-X mission – designed to study how energy and momentum is transported between different regions of space with a magnetic connection. The Black Brant XII missile is a 4-stage rocket. Peter Delamere, KiNET-X principal investigator from the University of Alaska Fairbanks said: “The aurorae – also known as the north pole or pole light, is formed when particles in the ‘near universe’ of the Earth’s ‘near space’. Earth interacts with the atmosphere Electrons in Earth’s space environment and in the solar wind are relatively low in energy, however, the aurora is produced by very high energy electrons. Vapors emitted from the rocket’s payload will generate magnetic interference and potentially energized electrons.KiNET-X consists of a single rocket launch carrying seven separable payloads – equipment primary diagnostic device, along with four small sideloads and clouds of barium vapor set to release from two additional, larger payloads”. Beautiful performance Analyzing further, meteorologist Katie McGraw told News 5 that when the launch happened, people in Northeast Ohio could see it thanks to clear skies. NASA called the May 16 launch of the Black Brant XII rocket a “beautiful display” and couldn’t have written a better story. Katie McGraw further revealed that the Black Brant XII rocket was used for the mission to explore energy transport in space. Black Brant is the result of research at the Canadian Arms Research and Development Facility (CARDE) in the 1950s into the nature of the upper atmosphere as part of ongoing research into anti-missile systems. ballistic fire and long-range communications. The launch took place on May 16 after a week of waiting. In 1957, CARDE contracted with Bristol to produce a simple rocket fuselage, called the Propulsion Test Vehicle, for high-powered solid fuel studies. Albert Fia’s design is quite heavy, as it is designed to accommodate a wide range of engine burn times, propellant loads and launch angles well suited to its role as a test vehicle for development. ABM system. The first test flight took place just two years later. CARDE’s attention then turned to long-distance communications, and they found the propulsion test vehicle system useful as a locating missile. To better suit this role, Bristol modified the design to be lighter and more suitable for the Black Brant missile role. CARDE has launched several Black Brant rockets over the years with the original Black Brant I design able to carry a payload of 68 kg to an altitude of 150 km and fly for the first time in October 1960. The missile’s design emphasizes payload reliability and range. There are 12 versions of the Black Brant and the Black Brant XII is a four-stage sonic launcher manufactured in 1995. The missile was first launched from the Andoya rocket range off the northwest coast of Norway and caused an explosion also known as the fear of Black Brant. This incident has put Russia’s nuclear forces on high alert, fearing a high-altitude nuclear strike could blind Russia’s radar, and Russia’s Cheget “nuclear briefcase” has been put on high alert. sent to Russian President Boris Yeltsin, who must then decide whether to launch a retaliatory nuclear strike against the United States. This is the first and only known incident to date where any nuclear-weapon country has activated its nuclear briefcase and prepared for an attack. On September 19, 2009, a Black Brant XII rocket launched to study the clouds caused calls from eastern North America reporting “strange lights in the sky”. NASA reported that the light came from an artificial noctilucent cloud formed by the exhaust particles of the rocket’s fourth stage at an altitude of about 278 km.

First hunting trip One winter day at the end of February. Around 11 o’clock at night, my father and I eagerly drove to the northern suburbs of Calgary – Canada with the expectation of seeing a colorful moving Northern Lights. Northern Lights), aka Aurora Borealis, in a clear cloudless sky. We had never seen them in our lives, and the information about their occurrence was contained in a news report released by the weather agency, with a prediction accuracy of 35%. However, for astronomy lovers, photographers living in this country of maple leaves know that, thanks to its location in the sub-Arctic region, with less light pollution, Canada has become one of the most beautiful places in the world. The most powerful and beautiful aurora active spot in the world. In particular, towns in the Northern Territory of Canada such as Yellowknife, Whitehorse, Iqaluit, … are the places where the aurora occurs most often. Therefore, it is not surprising that most tour operators here exploit this type of aurora viewing, with an attractive offer: visitors have a 90% chance of seeing this amazing phenomenon. Moreover, during the winter, from October to April next year, when Aurora often occurs, the whole North America region in general with the provinces of Alberta, British Columbia, Saskatchewan,… and the northwestern provinces of Canada in particular. also “follow” observing this masterpiece of art from this universe. Results of the first trip to hunt the first aurora in February 2021. Photo of Tran The Dung Turning onto the dirt road through the snow-covered meadows and the quiet scattered farms in the middle of the night, from the car, we looked up at the sky. There was no sign of anything out of the ordinary except for thousands of twinkling stars floating around. Going a little further, we discovered a faint cloud to the northwest and it seemed to be iridescent, flashing light and dark. Had to turn back and find a way to run right there to see clearly. Still not seeing the cloud glow green – a common signal when the aurora appears that many “Aurora hunters” talk about, but hunch plus unusual strange points around the clouds make them I believe this is the aurora. Even though it’s minus 20 degrees Celsius outside at the moment, we decided to take the camera out to shoot with exposure techniques, as the camera gathers light longer than the human eye. The result is stunning: a pair of ribbons of blue light against a starry sky appear on the camera monitor. The first Aurora hunting trip, with our own efforts, we discovered and captured “her”, although not gorgeous and magical, but also inspired us to continue to learn and accept. many useful experiences. The secret to finding “her” Aurora activity is monitored by spacecraft, and all data on their activity levels are converted to Kp readings, which range from 0 to 9. The higher the Kp number, the more likely it is to have an aurora. the larger the optical. Aurora appeared during a hunting trip in March 2021. Photo of Tran The Dung From Kp 5 and above, scientists warn that they are geomagnetic storms, or solar wind storms, because they can cause problems for radio stations, the national power grid, etc. However, with the Astronomy enthusiasts, photographers, this intensity ignited the hope of experiencing the most intense movement of light. However, that chance is only 50%, the rest is the weather factor. Must be clear sky, clear clouds. The intensity and duration of Aurora is as strong as a weather forecaster, but the risk is that they are hidden when they appear, sometimes dim, and sometimes appear like a red-haired teenage girl. On nights when the aurora is forecast to appear, with a level of Kp 5 or higher, they can stretch for thousands of kilometers, so it is likely to see “her” almost anywhere in Alberta, as long as at midnight when it is darkest and not polluted by light from urban areas, residential areas, full moon. Dispersion of artificial light or moonlight will interfere with tracking, reduce the ability to display the colors of the aurora, even when taking pictures will give inaccurate results. If you have no experience, it is better to go to the northern countryside, find the quiet country roads, the darkness is thick. Alternatively, consult the map of Aurora hunting spots on the Alberta Aurora Hunters Association website. However, the above tips to help people easily access the “Northern lights”, but no one is sure when it will appear, because this is a phenomenon of solar wind, beyond human control. Even forecast bulletins only give an accuracy of 35-50%, not to mention at the last minute it increases or decreases in level or disappears. Aurora appeared during the fifth hunting trip in April 2021. The author uses the Time-lapse technique to take over 200 photos and then combine them into a short clip of just a few tens of seconds to see the movement and splendid colors of the aurora. Photo of Tran The Dung Pursue to the end After the first trip, we continued to pursue three more times, but only once captured the “dancing girl” in a very short time. Our perseverance and perseverance are finally rewarded. It was near midnight on the last day of April, the weather in Alberta was beginning to spring, and it was also the end of the northern aurora hunting season in Canada. On a remote road in the city of Airdrie, more than 50km from home, Do Thanh and I – a Vietnamese photographer living in Calgary – drove to find a suitable location, prepare the hunt after receiving information. tonight aurora will appear with KP level 6 and many positive signs. We seem to be late because at this hour, every corner of the Airdrie farm area is parked with aurora enthusiasts’ cars. Not to mention, the car ran back and forth, rushing to find a place like going to watch hockey. There is indeed folly in chasing after something in the sky. In the end, we found a dilapidated old warehouse in the middle of nowhere to serve as the foreground for upcoming photos. As time went by, we still sat with our eyes wide and waited, forgetting the cold of minus 6 degrees Celsius. Occasionally, I headed to the north or northwest to take pictures to check the change of the sky showing blue colors. gem. Suddenly, wow, it showed up! Magnificent aurora lights appear in the province of Alberta – Canada. Do Thanh’s photo We both exclaimed as we saw the sky begin to sparkle before erupting in the shape of a bow and changing color continuously from yellow, green, blue to purple. Then “boom”, they move violently, sometimes dancing and undulating, sometimes shooting into the sky like fireworks. Imagine if there was a symphony orchestra at this time, this place would turn into a stage filled with splendid and magical light with many levels. We were hypnotized by them, confused, fumbling with our hands and feet, and then quickly switched to Time-lapse shooting (automatically taking multiple photos with equal exposure) to catch the changes of the aurora and make videos when needed, although shooting this type of photography will reduce the life of the camera. Returning home at more than 3am, we were both hungry and quite tired but our emotions were still high. Asked if he would go again next time, photographer Do Thanh shared: “Hunting aurora is similar to fishing, in addition to helping anglers practice patience and temper, it is necessary to observe, brainstorm to find understand prey; Once you’ve caught a fish, you’ll want to catch a bigger fish next time.” According to Roman mythology, Aurora was the name of the dawn goddess who traveled from east to west to announce the arrival of the sun, but in astronomy, Aurora means aurora – a strange optical phenomenon. Animals appear in the night sky in places located near the North and South poles of the Earth. They are produced by a stream of plasma particles from the solar wind entering the earth’s atmosphere and interacting with molecules, nitrogen and oxygen atoms and stimulating these molecules to emit light (Aurora) of all colors. color: cyan, blue, pink, red and purple with clicking or squeaking sound. Usually the aurora rays are bright at an altitude of 100 km and cover the vast sky. Tran The Dung (Ho Chi Minh City Young Generation Travel Company)
