China News Service, Nanjing, January 21 (Xu Shanshan) According to the Purple Mountain Observatory of the Chinese Academy of Sciences, on the evening of the 21st, the first "Mars and Moon" will appear in Tianyu.
As a planet that has attracted much attention from "earth people", Mars will "affectionately face each other" with the moon and stage a romantic "star and moon fairy tale".
Mars is known as the "little earth".
Due to the large brightness changes and the complicated trajectory, Mars was called "Fantastic" in ancient China.
The so-called "Mars conjoining the moon" means that the right ascension of Mars and the moon are the same, and the two are relatively close from the earth.
According to Hu Fanghao, an engineer at the Purple Mountain Observatory of the Chinese Academy of Sciences, if the weather is fine that day, after sunset, the public will see the eight-month-old gibbous moon and red Mars "walking" in the night sky.
"In addition to observing with the naked eye, it is better to use a telescope to observe the "Mars and Moon". With the help of a telescope, you can also find Uranus among them." Hu Fanghao said.
At 8 o'clock on January 22, Mars and Uranus "conjunct", and the two star-shaped shadows follow each other and reflect each other, as if lovers are whispering, and then write Tianyu's "Romantic Covenant".
At that time, Mars and Uranus will have the same right ascension and similar declination.
Hu Fanghao suggested that since Mars and Uranus have not yet risen at this time, you can choose to watch with "Mars conjunct the moon" on the evening of the 21st.
Don't regret it if you miss it.
On February 19, "Mars and Moon" will appear again.
Hu Fanghao said that by then, Mars will "hold in hand" a red giant star-Bi Suwu, and continue to "guard" the moon in the sky.
