The beautiful celestial phenomenon of "the new moon embracing the old moon" appears in the sky. What exactly is the new moon embracing the old moon?

On the morning of November 13, the beautiful phenomenon of "new moon embracing the old moon" and the romantic celestial phenomenon of "Venus conjunct the moon" appeared in the low sky in the southeast. The new moon embraces the old moon? It means that in the embrace of the crescent moon, the entire moon surface is vaguely visible. Zhao Zhiheng, an astronomy education expert and director of the Tianjin Astronomical Society, said that this phenomenon is caused by the reflection of sunlight from the earth's surface to the dark side of the moon. Under clear weather conditions, during the waning moon and crescent moon periods, almost the entire bright moon surface can be seen with the naked eye. The new moon embraces the old moon? This beautiful phenomenon is very suitable for taking pictures, especially when there are other bright celestial bodies near the moon, such as bright stars, comets, etc., the picture will be very beautiful. ?Zhao Zhiheng said.

Coincidentally, Venus, which appears as a "morning star", happens to appear near the waning moon on the morning of the 13th. As the brightest celestial body in the sky after the sun and the moon, Venus often coincides with or accompanies the waning moon (or crescent moon), which is the most beautiful scene in the night sky - a fairy tale of stars and moon. These two brightest objects in the night sky compete with each other and stand out in the hazy sky until the first ray of dawn comes. ?Zhao Zhiheng reminded,??If the atmospheric transparency is good enough, not far to the lower right of Venus, if you look carefully, you will find a light blue bright star. This is the star Spica, which is the main star of the constellation Virgo. ?

There is more than one month left in this year. In the remaining time, we can still see these beautiful celestial phenomena.

Among the celestial phenomena worth seeing, the Leonid meteor shower: it will reach its peak on the night of November 17th to 18th. For this Leonid meteor shower, if you are in a big city, you can witness about 2 meteors per hour in the second half of the night. By then, the shower's radiant (the point in the sky where the meteors appear to originate) will be above the southeastern horizon. If you are in a place with little light pollution, you can ideally see about 15 particles per hour. Fortunately, this meteor shower coincides with the waxing moon, so people have plenty of time to view the shooting stars.

On the evening of November 19, Jupiter and Saturn will stage a "double star with the moon". "Double Stars Accompanying the Moon", Jupiter and Saturn will join the moon at 4:27 on the evening of the 19th and at 10:57 at night respectively. In the evening, you can see a crescent moon walking between Jupiter and Saturn in the southwest. .

The penumbral lunar eclipse on November 30th. When the moon is in the penumbral area of ??the sun, a penumbral lunar eclipse occurs. Part of the sunlight reaching the moon is blocked, and most of it is not blocked. So I can only see the moon dimming at a certain angle. The penumbral lunar eclipse will appear beautifully on November 30. However, since the moon will rise after the lunar eclipse begins, only part of the lunar eclipse can be observed in most parts of China.

The Geminid meteor shower will be held at 9:00 on December 14. This Geminid meteor shower is very suitable for observation. The moon is near the new moon and there is no moonlight interference. The hourly meteor occurrence rate at the zenith is expected to reach 150.

The spectacular conjunction of Jupiter and Saturn on December 21 only happens every 20 years. The last time was in 2000. On December 21st, Jupiter and Saturn will stage a rare "Jupiter-Saturn conjunction" celestial phenomenon. By then, using binoculars, you can simultaneously observe the surface details of Jupiter, the rings of Saturn, and several of their bright moons in a small field of view.

The Ursids meteor shower will be held at 17:00 on December 22. This is the last meteor shower in 2020. The active period is from December 17 to 26 and reaches its maximum on December 22. As the meteor group with the highest radiant declination, the Ursid meteor shower has a small flow rate of about 10 to 50 meteors per hour, but it is very suitable for observation in the mid-to-high latitudes of the northern hemisphere.
