In the middle of the two stars with the moon blooming "red-eyed smiling face"
News from our newspaper (Reporter Niu Weikun) In early spring in March, the temperature turns warmer and star watching outdoors becomes more pleasant.
In March, the sky will show astronomical phenomena such as the conjunction of the Pleiades of Mars and the opposition of Vesta.
The most ornamental celestial phenomena appear on the evenings of March 18 and March 19, when Mars, Aldebaran and Crescent Moon will bloom together with "brilliant smiling faces."
According to the Beijing Planetarium, among the 5 planets visible to the naked eye, only Mars is worthy of attention in the sky in March. It goes direct in Taurus, falls at midnight, and is visible in the first half of the night.
There will also be a scene of the Mars Pleiades star cluster on March 4.
The Pleiades star cluster is a very well-known open star cluster, visible to the naked eye on clear nights; however, in cities with serious light pollution or when the atmosphere is not very transparent, it is still difficult for beginners to find the Pleiades cluster.
The Pleiades star cluster on Mars provides an easy opportunity to find it: at about 20 o'clock on March 4, looking to the southwest, the red Mars can be distinguished at a glance, and there is a fuzzy cloud and fog not far away, that is, the Pleiades star cluster. .
After Mars conjunct the Pleiades, the fourth asteroid Vesta will oppose the sun on March 5.
According to experts, from the earth, Vesta is the brightest asteroid. In the absence of light pollution, astronomers can challenge to find this asteroid directly with the naked eye.
If the weather is not ideal, you can also choose a similar date for observation.
The next opposition of Vesta will occur in August 2022.
On the evening of March 18th and March 19th, a smiling face can be easily seen in the clear western sky-the beauty of "Double Stars with Moon" will be staged, with smiling faces blooming on Mars, Aldebaran and Crescent Moon.
According to experts, the brightness of the two "eyes" is relatively close this time, and it is more beautiful than the "big eye" and "small eye" smiles that have happened before.
Why are the "eyes" of the smiling face red?
Experts explain that Martian soil contains a lot of iron oxide. When iron oxide reflects sunlight, there are more red wavelengths, making Mars look red. Bi Aldebaran is a red giant star.
"This time, the facial features of the'red-eyed smiling face' are relatively correct, lasting a long time, and it is very worth seeing!"
