Illustration. Comet Hale-Bop orbited the sun in 1997 and became one of the brightest comets in history. It was a lasting “gift”, as it could be seen with the naked eye for over 18 months (a record). 2. Cloud hole – circle opens to heaven Imagine that on a cold day and the horizon is densely cloudy, suddenly, you see a giant hole that you can see through the sky. This phenomenon is called cloud hole. It occurs when a large number of small ice crystals break into the cloud layer causing the water droplets to evaporate. Although explained by the laws of physics, this phenomenon is still extremely miraculous. 3. Mist rainbow looks like albino rainbow When you see this phenomenon, you may think that you have lost the ability to distinguish colors. Stay calm and enjoy looking at it, a foggy rainbow like “brothers” to the albino rainbow. Instead of being made up of water droplets, it is made up of tiny dewdrops. Because they are smaller, they only reflect white, making this phenomenon look quite spooky and mysterious. 4. Lava on Hawaii Beach In May 2018, the Kilauea volcano in Hawaii exploded. It began spewing ash into the air and spewing dense plumes of lava to the Pacific Ocean. It also travels great distances, destroying the largest natural freshwater lake in Hawaii. It also spread to the beaches, filling Kapoho Bay and extending new land nearly a mile into the sea. 5. Comet West near the Sun in 1976 Comet West was described as one of the brightest objects to pass through the solar system in 1976. Its nucleus split into four pieces, providing a spectacular view of its long tail. At the time, it was one of the very few comet breaks observed. 6. Pyroclastic flows produce volcanic lightning When a volcano erupts, it releases pyroclastic flows, a fast-moving stream of hot gas and ash. Sometimes these materials mix and match with extreme heat creating an amazing light show. 7. Rare waterfall rainbow in Yosemite National Park Only a few lucky people have witnessed first-hand the sight of Fallveve Falls in Yosemite National Park turning into a rainbow. This is a great example of what happens when sunlight is reflected on water droplets. These images look edited but nature is really full of color and imagination. 8. Frozen waves detected on the coast of Croatia A violent storm toss these monster waves, which then froze in sub-zero temperatures in 2012. This left the coast of Senj, Croatia covered in hard ice that looked like ice . 9. The desert “revives” and blooms California’s “super blooms” usually happen about once every 10 years. This phenomenon requires a perfect “storm” of conditions: steady rain, warm temperatures and low winds. The desert will turn into a colorful picture when thousands of wildflowers bloom at once. A wonderful gift of nature! 10. Super blood moon rises behind the Parthenon in 2018 A total lunar eclipse that is a supermoon is a relatively rare phenomenon. In the 21st century, there are 87 total lunar eclipses, of which only 28 are supermoons. Skywatchers could see a “bulging” supermoon and a combined lunar eclipse for the first time in decades, the moon now bathed in a fiery red light. 11. Bubble clouds If we see the sky shining as if there are giant soap bubbles floating, we are not hallucinating, but witnessing clouds of bubbles. This phenomenon occurs only when very uniform drops of water diffract the sunset light. 12. Himalayas appear for the first time in 30 years In April 2020, the level of pollution dropped sharply, making the image of the splendid Dhauladhar mountain range again. This is part of the Himalayas and can now be seen even from Jalandhar – 143 miles away. 13. Snow falls in spring in Tokyo Seeing snow in Tokyo is pretty special, but what makes it really surprising is that it happened in April while the cherry blossoms were in full bloom. Tokyo snows about 7.6 times per season, mainly in January and February. And this is the first spring snowfall in 32 years. 14. Midnight sunset reflected in a waterfall in Iceland During the summer months in Iceland, the sun is still visible at midnight local time and we can enjoy the sunset at 1:30. In this photo we can see the sunset shining at 196 feet of Seljalandsfoss waterfall, which is breathtaking!

Total lunar eclipse in Mechelen, Belgium, January 21, 2019. Photo: Getty Images. On the evening of May 26, the first total lunar eclipse in more than two years will coincide with a super moon in a special combination of the universe known as a “super blood moon”. The best place to observe this eclipse will be in the middle of the Pacific Ocean, all of Australia, east of Asia and west of the Americas. Vietnamese astronomy lovers can also observe this phenomenon. A total lunar eclipse will last about 15 minutes as the Earth passes directly between the moon and the sun. The entire phenomenon will last five hours, as Earth’s shadow gradually envelops the moon, then begins to diminish. The moon will be orange-red when all sunrises and sunsets in the Earth’s atmosphere are projected onto the surface of the eclipsed moon. Why is it called a super moon? A supermoon occurs when the moon is full at the point where the moon’s orbit brings it closest to Earth. And the “blood moon” appears as it moves through the Earth’s shadow, blocking the light from the sun. A combination of such events will occur on May 26, with a total lunar eclipse followed by a partial lunar eclipse, the moon appearing in red, then fading to gray. The moon’s orbit around the Earth is not a perfect circle. This means that the moon’s distance from Earth changes as it orbits the planet. The closest point in orbit, called perigee, is about 45,000 kilometers closer to Earth than the farthest point of the orbit. A full moon that occurs near perigee is called a supermoon. The Moon when it is closest to Earth is about 12% larger than when it is furthest. Source: Wikimedia. So why call it super? The Moon’s relatively close proximity makes it appear slightly larger and brighter than usual, although the difference between a supermoon and a normal moon is often barely noticeable unless you’re looking at the two side-by-side photos. together. The moon’s orbit is not a perfect circle. Source: Wikimedia. How does a lunar eclipse work? A lunar eclipse occurs when the Earth’s shadow covers all or part of the Moon. This can only happen during a full moon, so first, let’s understand what makes a full moon. Like the Earth, half of the moon is illuminated by the sun at any given time. A full moon occurs when the moon and sun are on opposite sides of the Earth. This allows you to see the entire illuminated side, which looks like a circular disk in the night sky. If the moon had a perfectly flat orbit, each full moon would be a lunar eclipse. But the Moon’s orbit is tilted about 5 degrees relative to Earth’s. So most of the time the full moon lies slightly above or below the shadow formed by the Earth. But twice in each lunar orbit, the moon lies on the same horizontal plane as both the Earth and the sun. If this corresponds to a full moon, then the sun, Earth, and moon will form a straight line, and the moon will pass through the Earth’s shadow. This leads to a total lunar eclipse. To see a lunar eclipse, you need to stay awake at night, when the moon passes through the shadow. The phases of the moon correspond to how bright humans can see from Earth. Source: Wikimedia. Why is the moon red? When the moon is completely covered by Earth’s shadow, it will darken, but not turn completely black. Instead, it is red, which is why a total lunar eclipse is sometimes called a red or blood moon. Sunlight contains all colors of visible light. The gaseous particles that make up the Earth’s atmosphere are more likely to scatter light of blue wavelengths while red wavelengths pass through. This is called Rayleigh scattering, and it’s why the sky is blue, and sunrises and sunsets are often red. Earth’s atmosphere gives the moon its blood-red glow during total lunar eclipses. Photo: Wikimedia. In the case of a lunar eclipse, red light can pass through Earth’s atmosphere and be refracted – or bent – towards the moon, while blue light is filtered out. This causes the moon to appear light red during a lunar eclipse. How does Vietnam watch the total lunar eclipse? According to the Vietnam Astronomical Association (VACA), Wednesday evening, May 26, in Vietnam, most of the central and southern regions will be able to observe the full phase of this phenomenon, while in the north only partially traceable phase. Total lunar eclipse time in Vietnam: – Midnight lunar eclipse begins: 15:47 – Partial lunar eclipse begins: 16 hours 44 minutes – Total lunar eclipse starts: 18:11 – Maximum lunar eclipse: 18 hours 18 minutes – Total lunar eclipse ends: 18 hours 25 minutes – Partial lunar eclipse ends: 19:52 – Midnight lunar eclipse ends: 20 hours 49 minutes. 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 o’clock, this partial phase still has very high coverage and is 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 southern provinces will be able to track the entire phase if the viewing angle is wide enough to see the eastern horizon. In Ho Chi Minh City, the moon rises at 18:07, that is, before the total phase begins, and therefore observers in this area and surrounding areas can fully monitor the total phase. Although the total phase can be seen in many areas, at that time the moon is so low that it will be difficult to see in places where visibility 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 houses, roofs or windows of high-rise buildings, the coast… On November 19, astronomical lovers around the world will continue to see an almost total lunar eclipse, the moon dims but does not turn red like this time. The next total lunar eclipse will occur in May 2022. The last total lunar eclipse was in January 2019.

In the region, the South and the Central Highlands provinces, many places are having rain and unfavorable weather. This will directly affect the observation of the lunar eclipse. In the sky of Hanoi, according to the forecast about 6:30 p.m The Moon will begin to appear on the horizon. At this time, it is possible that the Moon has appeared but is located right on the horizon and is being obscured by buildings. In Hanoi, viewers can observe the Lunar Eclipse in the direction between East and Southeast. However, right now (18:20) there are some pretty big clouds near the horizon. Photo at 6:20 pm in Hanoi Photos at 6:30 p.m. The sun was slowly disappearing. Theoretically, the Moon is now close to the horizon to the East, Southeast. From 6:45 pm to 7:00 pm, when the moon is high enough, this is convenient for viewers to observe. According to reflection, in Ninh Thuan, the Moon has begun to rise and viewers can observe. In Da Nang, the weather is nice and viewers can observe well. The Moon now has just finished its total phase, the Moon is gradually moving out of the shadow. Pictures at 6:30 pm In Ha Tinh: The coastal area can be observed well. Viewers can find the Moon in the East, Southeast. Some mountainous areas of Ha Tinh may have rain, making it difficult to observe. In Taiwan, a place very close to Vietnam, the weather conditions are favorable, so observing the lunar eclipse is quite easy. Below is an image of a lunar eclipse recorded in Japan. At this time, the Moon has passed its total phase and is gradually leaving the dark side of the Earth. Pictures in Japan Quang Ngai: The lunar eclipse has begun to appear.

Photo taken during the Lunar Eclipse in Hanoi at 19:15 on May 26. At this time in some places in Hanoi it is windy. This will have a certain effect on those observing with a telescope. In Ho Chi Minh City at this time it is cloudy, viewers have almost no chance to observe the lunar eclipse. In Hanoi, 60% of the Moon has left the Earth’s shadow. According to forecast, the lunar eclipse will end at 19:52′. Thus, there is only about 30 minutes left for viewers to observe this phenomenon. 19:30: The lunar eclipse was recorded in Hanoi at 19:30. At this time, 70% of the area is bright again. 70% of the Moon was bright again at 19:30, observed from Hanoi. 19:45 : Image of lunar eclipse recorded in Hanoi.

The Moon has almost completely come out of the Earth’s shadow. 19:55 : In Hanoi, the partial lunar eclipse has ended. The Moon is now moving into the Earth’s semi-dark region. In about 1 hour, from 20h00 to 20h49, there will be a penumbral lunar eclipse. At this point, the Moon will be slightly darker and dimmer than usual. After 9pm tonight (May 26), the lunar eclipse will end completely. At that time, the entire Moon will be directly illuminated by the Sun again. Live: Total lunar eclipse and super moon Vietnam on May 26 26 Today’s lunar eclipse coincides with the time when the Moon is at its closest position to the Earth. Therefore, observers will be able to witness the dual phenomenon of lunar eclipse and supermoon. Simulation of a lunar eclipse. This lunar eclipse in Vietnam will be different when accompanied by a super blood moon phenomenon. In the legends of some cultures, lunar eclipses are often associated with some bad luck. In ancient times, it was believed that a lunar eclipse was a sign of great change and foreshadowed bad luck to come. In modern times, many people still hold bad views about this phenomenon. Readers can visit here for a correct and accurate understanding of the lunar eclipse. This year, Vietnam is located in a geographical area that can observe the lunar eclipse well. However, depending on the region, the ability to observe as well as the time to observe the lunar eclipse varies between provinces. According to the National Center for Hydro-Meteorological Forecasting, some areas this afternoon will have very favorable weather to observe the lunar eclipse. Readers can visit here to know exactly where they live, whether this phenomenon can be observed. Landmarks of the afternoon lunar eclipse, May 26 (Vietnam time): – 15:47: A penumbral eclipse begins, the Moon enters the Earth’s penumbra and begins to decrease in brightness. – 4:44 pm: A partial lunar eclipse begins, the Moon enters the Earth’s shadow and gradually becomes partially obscured. – 18h18: The lunar eclipse is at its maximum, the Moon is located near the center of the shadow. – 6:25pm: The total lunar eclipse ended, the Moon began to emerge from the Earth’s shadow. – 6:35 pm: when the Moon rises from the horizon. – 19:52: The partial lunar eclipse ends, the Moon enters the Earth’s semi-dark region. – 20:49: The penumbral eclipse ends, the Moon comes out of the Earth’s penumbra.

Photo: Getty Images. A supermoon occurs when the moon is full at the point where the Moon’s orbit brings it closest to Earth. And the “Blood Moon” appears as it moves through the Earth’s shadow, obscuring the light from the Sun. A combination of such events will occur on May 26, with a total lunar eclipse followed by a partial lunar eclipse, the Moon appearing in red, then fading to gray. Right after sunset on May 26 (the full moon of the fourth lunar month), a “super blood moon” will hang in the sky to the east-southeast of Ho Chi Minh City. At this time, the supermoon and total lunar eclipse will combine to create a rare celestial image. This is Asia’s first total lunar eclipse in nearly three years – a brief but dramatic sight. This spectacle was observed for only 15 minutes from around the Pacific Rim, over the entire night part of the Earth. At this time, astronomy and sky lovers are hoping that the full moon night of April will be clear so they can watch the Moon turn red-orange. Phases of total lunar eclipse observed in Hong Kong in 2011. Photo: AFP What causes the “Super Blood Moon”? The Moon orbits Earth in an elliptical orbit every 27 days, so every month there is one point when it is furthest from Earth and another when it is closest. This moving closer and further away causes tides in the oceans. When a full moon occurs at the point closest to the Earth, it is called a Super Moon. Supermoons have occurred several times this year, but this “Flower Moon” will be the closest of the year. “Sister Hang” will be located 357,311km from Earth just 9 hours before the “Blood Moon”, or total lunar eclipse. As a result, the full moon in April this year will be about 8% larger than the full moon on average. Usually that means a brighter moon, but not this month. However, those interested are looking forward to seeing the “king tide” in Victoria Harbour, Hong Kong. The blood moon eclipse, the longest of the 21st century, was observed over Hong Kong on July 27, 2018. Photo: Getty Images. When does a total lunar eclipse happen? The “blood moon” is the result of the full moon moving through the Earth’s shadow. This phenomenon can happen when the Earth is between the Sun and the Moon, but not often because the Moon’s orbit around the Earth is eccentric, so it usually moves below or above the Earth’s shadow. If not, there would be a total lunar eclipse every month. The last time there was a partial lunar eclipse in Hong Kong was on July 17, 2019. Illustration of a total lunar eclipse that occurs when the Moon is completely in the Earth’s shadow. Why did the “Super Blood Moon” turn red? The only light you’ll see at the Moon as it rises over Hong Kong will be filtered by the Earth’s atmosphere first. The sun looks orange-red at dusk and dawn because red light has the longest wavelength. As a result, it moves through Earth’s atmosphere more easily, colliding with fewer molecules in the air as it passes (while blue has the shortest wavelength, thus hitting more obstacles and scattering, that’s why the sky is blue). The same thing happens during a total lunar eclipse. Because the Earth lies between the Sun and the Moon, light that can reach the Moon must first pass through the Earth’s atmosphere. People take pictures of the lunar eclipse from the Avenue of Stars in Hong Kong in October 2014. Photo: AFP. When can you see the “Super Blood Moon”? The Pacific Rim – which includes East and Southeast Asia, Australia, New Zealand, the island nations of the Pacific Ocean and the west coast of the US – will be able to see the total lunar eclipse on May 26. People in eastern Australia, New Zealand and Hawaii are said to have the best views of the “Blood Moon”. According to the timeanddate website, in Ho Chi Minh City, the moon rises at 6:07 pm on May 26, but at a low position and the total lunar eclipse phase will make the moon too dim, difficult to track until the moon rises. over the sky and the total lunar eclipse ends.

Those interested are encouraged to go to high points or areas with a clear view of the East-southeast of the City for the best view of the lunar eclipse. At 18:18, the total lunar eclipse is at its maximum; and at 18:25: Total lunar eclipse ends. At 19:52: The partial lunar eclipse ends and at 20:49, the penumbral eclipse also ends. What will the “super blood moon” be like? There are a few different phases to this lunar eclipse. The full Moon will be completely obscured – and reddish – for 15 minutes before it moves out of Earth’s shadow and the left side of the Moon begins to shine. Over the next 92 minutes, the Moon will be less red. Once completely gray again, the moon will remain in the Earth’s shadow and will look like a dim full moon. People take pictures of the lunar eclipse from the Avenue of Stars in Hong Kong in October 2014. Photo: AFP With a clear sky, it would be a strange sight. Because a total lunar eclipse occurs just as the Moon is rising, you may find the red full moon looks larger than average. When the 15 minutes of total lunar eclipse are over, if the sky is still clear blue, then the best scenes can appear. After the “blood moon” phase, the Moon will drift out of the Earth’s shadow, but the partial lunar eclipse (“half-blood moon”) is now as strange a sight as the total. As the full Moon rises higher in the sky, you’ll be able to see a slight curve above it. It is the edge of the Earth’s shadow in space projected onto the surface of the Moon. It is one of the strangest images of nature.

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.
