Here are the most prominent astronomical phenomena that occurred in the Earth's sky in 2021.

1. April Red Moon

According to the Yearbook of Old Farmer's Almanac, the April 2021 super pink moon will occur on the 26th - the time when the Moon and the Earth are closer to normal. This is the first supermoon of 2021 and also one of the largest and brightest supermoons of the year.

2. practical Japanese medicine

A fire-cylinder solar ecstasy, also known as a spherical solar ecstasy, occurs when the Sun, Moon and Earth are in a row at the time when the Moon is at the farthest point from Earth on its orbit. Because it is too far away, the Moon cannot completely obscure the light from the Sun, leaving a fire circle around a dark globe.

This rare phenomenon occurred on June 10 this year.

3. Strawberry Moon

Strawberry Moon lights up the sky on June 24, 2021, marking the last supermoon of 2021.

According to the Farmer's Almanac book in the US, the full moon of June is often called Strawberry Moon, because indigenous American tribes often harvest strawberries in North American regions at this time of year.

Strawberry Moon usually marks the last full moon of spring or the first full moon of summer. It is also known as the green corn moon or honey moon.

4. Mars star "marries" Kim before breaking up

On July 7, 2021, Mars was about 6 times the diameter of the full Moon. The two have been drawn closer to each other every day as Mars climbs near the western horizon and the Red Star slides east to meet it. The pair closest approached each other on July 12 - just one moon diameter (3,474km). Unfortunately, Mars is too blurred to see with the naked eye. Even with a couple, Mars is much Delegated compared to a star, just like a ray of fire.

5. Perseid iceberg rain is the most beautiful of the year

The beautiful Perseid ice rain performance in 2021 took place from the night of July 14 and lasted until mid-August. It reached its peak on August 11-13, when there were up to 100 black stars per hour.

According to NASA, the Perseid ice storm is one of the most brilliant ice rains, best known for the rising night sky with burning meteorite as the Earth passes through the dust of the Swift-Tuttle Compass.

The Perseid ice age is named after the constellation Perseus, where its rays of light seem to have issued from the constellation and can be seen with the naked eye anywhere in the world.

6. Two heavy ice rains hit peak overnight

According to the American order of the iceberg Association (AMS), the South Delta Aquariids iceberg reached its peak with the Alpha Capricornids iceberg on the night of July 28.

The South Delta Aquariids iceberg will be available from July 12 to August 23 this year, while the Alpha Capricornids iceberg will be available from July 3 to August 15. Both ice rains continued for many weeks after reaching their peak.

7. Strange green meteorite shakes Turkey

A blue meteorite has been discovered near the Turkish city of Izmir. It fell to Earth early in the morning of July 31 (local time) accompanied by a loud explosion.

The object was part of an iceberg event on Earth at the time, according to Dr Hasan Ali Dal, deputy director of the Aegean University Observatory.

The green color of the iceberg in Izmir may stem from its chemical composition, signaling that it contains a large amount of nickel.

8. The trio of stars create a strange astronomical phenomenon in the night sky

Space.com reported that on the evening of September 9, the Lunar calendar, along with its two brightest stars, Star Kim and Star Spica, formed an interesting triangle in the night sky.

About 45 minutes after the Sun sets, the Golden Star appeared above the west-southwest horizon, floating near the Lunar calm moon just above the right. Sliding down below is Spica, a female star cluster. Kim is now 11 times brighter than Sirius - the brightest star in the Earth's night sky. While the new moon is entering its third day in the cycle, it should be about 11% brighter.

9. The longest part of the 21st century

The longest total moon of the 21st century - known as Beaver Moon - took place on November 19 and lasted 6 hours and 2 minutes, according to Space. The moon was covered by 97% of the Earth's bulge at 2:02 p.m. Vietnam time.

Millions of people from all over North America, Central and South America, as well as parts of Australia, Europe and Asia have been able to admire this fascinating astronomical phenomenon.

Although it is not a real blood moon or a full moon, the Moon is still " reasonfully" deep in the darkness of the Earth and turns red due to the reflection of light in the atmosphere of the planet.

10. Full authenticity

The 2021 total autumn of the year occurred on December 4 and was only seen in the Southernmost and South Atlantic.

Like most menstrual periods, the menstrual cycle on December 4 is relatively short. In total, menopause time can only be seen in 1 minute and 54 seconds in the South.
