Part of Vietnam will see the total lunar eclipse, while the remaining areas will observe the partial lunar eclipse with a very high coverage rate. Vietnam can only see the latter stage of the phenomenon A lunar eclipse occurs when the Sun, Earth, and Moon are aligned (or nearly aligned) with the Earth in between. At this time, the Moon enters the shadow region behind the Earth and receives only a fraction of the light from the Sun than if it did not enter this region. For this reason, part or all of the Moon will be darker than usual and appear crimson. A lunar eclipse is a phenomenon that is not too rare and is easy to observe even without the aid of any instrument. Even so, it is still an interesting optical phenomenon and attracts many people’s attention. Particularly with the lunar eclipse that will take place at the end of May, many places in Vietnam will be able to track part of the total phase of the lunar eclipse. Therefore, this is indeed a remarkable phenomenon. Lunar eclipses are not uncommon, but observing the total phase is still something quite special. This lunar eclipse lasted for a total of more than 3 hours from the beginning to the end of the partial phase. If the semi-dark phase is included, the total duration of the phenomenon is more than 5 hours. However, because in the early phase of the lunar eclipse, in Vietnam, the Moon has not yet risen above the horizon. Therefore, observers in Vietnam can only observe the later stages of this phenomenon. Detailed schedule of the phenomenon in Vietnam time on May 26 specifically: Midnight lunar eclipse begins: 15:47; Partial lunar eclipse begins at 16:44; Full lunar eclipse starts at 18:11; Lunar eclipse at 18:18; Total lunar eclipse ends at 6:25 pm; The partial lunar eclipse ends at 19:52; The lunar eclipse ends at 20:49. In the Northern region The moon rises above the horizon at the end of the total phase. The observer can only track the partial phase of the phenomenon. For example, in Hanoi, the Moon rises at 6:29 pm on May 26. Thus, the observer can almost fully follow the later phase of a partial lunar eclipse from that point to its end. Sometime before 19:00 this partial phase was still very high coverage and very noticeable. In the Central and Southern regions Most of the central provinces will be able to track the last part of the total phase, while most of the southern provinces will be able to fully track the full phase if the viewing angle is wide enough to see the eastern horizon. For example, in Ho Chi Minh City, the Moon rises at 18:07, that is, before the total phase begins, so observers in this area as well as the surrounding areas can fully monitor the phase. totality. Although the total phase is visible in many areas, at that time the Moon is so low that it will be difficult to see in places where the view to the East is obstructed. The most favorable observation positions to monitor this period are places with a wide view to the East, areas without front shelters, roofs or windows of tall buildings, the coast… Notes to remember A lunar eclipse is completely harmless to your eyes, so you can look directly at it. You also don’t need specialized equipment like a telescope or binoculars to observe this phenomenon, although if you do, it will be a much more interesting view. Basically, there are two things to keep in mind with respect to observations: Weather is always important. If it is raining, stormy or cloudy, the phenomenon cannot be observed. Therefore, you need a cloudy sky. In general, as long as you see the Moon and it continues not to sink behind some cloud, you can observe a lunar eclipse. Choose a viewing spot so that you can see the eastern sky with as wide an angle as possible, avoiding artificial light (street lights, building lights) shining directly into your eyes from above. Another partial lunar eclipse that can be observed by observers in Vietnam will take place on November 19 of this year, but this May phenomenon is more noticeable because of its clear cover. Finally, a note on terminology, a lunar eclipse is a lunar eclipse, not a “blood moon” (an imprecise but popular term in the last few years). This is also a very normal optical phenomenon, not related to any spiritual or religious factors.

Simple happiness In addition to green vegetables, I also grow fruit trees: green grapefruit, guava, apple and sapote. In some years, the sapote tree produces dozens of fruits, sparrows and crested birds come to eat when the fruit is ripe and sweet. The first time I was observed from above, I suddenly had an O in my mouth and an O, because I saw so many other gardens on the terrace, just like my house. And every day, my hobby is going up to the rooftop to use binoculars to look at the trees of the houses on the same street and on the opposite street. Then discovered and became acquainted with a neighbor. He raised nearly 40 bamboo chickens and planted a lot of lemongrass on… the roof of a nearby house. Garden corners on the terrace of townhouses. Photo: DINH THU HIEN – CAM NHUNG Notice that people are quite crowded on the terrace in the early morning and late afternoon. The orchids drop down, are sprayed with cool water. The gourd of a terrace with many fat fruits, surely the owner cannot eat it in time, perhaps it will be picked soon to give to friends and relatives. But the most interesting thing to mention is the dozen cherry tomato plants in the back (terrace) of the house. Green fruit, sweet fruit, red fruit like vermilion, toothpicks on the tree. The owner must have fertilized, watered and cherished so much that the tree was so wrong. Sometimes, binoculars let me see couples happily watering their plants in the early hours of the morning. And together they do some warm-up exercises on the terrace, next to the energetic vegetable garden, before the sun rises in the East. Family happiness is as simple as that. Husband and wife each day cultivate seeds and plant trees, just like how they build a home. If you don’t take care and keep it, how can you create the joy of life? So going through rainy and sunny days, trees need internal energy to sprout green and also need the care and love of the owner. Life balance place Many people think that the townhouses are cramped, where is the land for gardening? In my eyes, the terraces of townhouses are the perfect place to set up a garden. It can be the yoga floor every morning, relaxing by the surrounding plants, it can be the joy of picking clean fruits and eating organic greens. The gardens in that street are the cool green of the crowded and typical smoky city. Each beautiful garden on the terrace contains the owner’s love. Sometimes I think that’s also how the human mind responds most tenderly and lovingly, with all the unhappiness and anger around. Whenever the whole family goes on a long trip, the first thing I worry about is the life of the plants on the terrace being threatened. The guava trees are grown in styrofoam boxes but also bloom white flowers, must pay attention to watering so as not to wither because of lack of water but also not to stagnate too much water to damage the roots. When it comes to flowers, the homeowner will sometimes have to pollinate them because few bees and butterflies visit. But that green area is really the place to balance the existing life of people. Trees are like lovers who are always loyal and knowledgable. If enough love and care, the tree will be green and fresh. If left alone, the soil is dry, not fertile enough to feed the tree, of course the tree must wither. If only each townhouse had a green garden on the terrace, instead of lead gray corrugated iron roofs, the city would have a different beauty and soul, much more positive and gentle… Expanding urban green space There are no statistics on the area of ​​green space created on the area of ​​townhouses, but this area is certainly not small for urban areas with large urban residential areas like Ho Chi Minh City, especially when locals People tend to take care of their own health and prefer to live closer to nature. This can be considered as an expanded green area for urban green space, which is seriously imbalanced in the process of rapid urbanization but is inadequate in terms of planning.

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 ”.
