What are the main constellations in the sky in spring? How to identify.

The Big Dipper hanging high in the northern night sky is the most familiar star. Learn to recognize the constellation of spring and start with it. The Big Dipper is a part of Ursa major. It consists of five bright second-class stars and two third-class stars in the shape of a spoon, just like an ancient vessel for holding wine, hence its name. As for the name Beidou, it is also different from the six stars in Nandou. The six stars in Nandou are also arranged in a barrel shape on Sagittarius, hanging low in the summer night sky. The Big Dipper is equivalent to the waist and tail of Ursa major. Four of them make up a bucket spoon, and the other three make up a bucket handle. At dusk in spring, the big dipper of the Big Dipper points to the east. Connect a straight line between Tian Xuan and Shu Tian at the front of the Big Dipper, extend the distance by five times, and you will meet a bright second-class star, which is the North Star. This is the easiest way to find Polaris. Therefore, Tian Xuan and Shu Tian are also called "finger stars". Because the Big Dipper revolves around the North Star constantly, and its height and position change from time to time, you should practice finding the North Star quickly through the Big Dipper at any time. The bucket handle part of the Big Dipper is slightly curved. If you stretch out along the arc of the three stars on the bucket handle, you will meet an orange-red bright star, which belongs to Capricorn and is named plantain in Chinese. Capricorn is a big constellation, but it is difficult to identify because of its scattered structure. However, it is not difficult to find it through the Big Dipper.

If you continue along this arc, you will meet another star with blue and white brilliance near the ecliptic. The Chinese name of this star is Jiaokou, and its bright and clear brilliance has been impressive since ancient times. Jiaokou is the main star of Virgo, clear but not cold, beautiful but not gorgeous, just like a dignified and delicate girl. In ancient constellation books, Virgo appeared as a goddess. Virgo is a scattered star and can be identified in stages. Learn to recognize the corners first, and then gradually get familiar with Virgo from part to whole through frequent observation. A white star like 1 is shining brightly in the sky to the west of Arcturus. This is the main star of Leo, and its Chinese name is Xuanyuan XIV. Like Arcturus, it belongs to one of the nine planets for navigation. Besides Xuanyuan XIV, Leo also includes two second-class stars and four third-class stars, which is an easily recognizable constellation. In addition to the above, the constellations you can see in the Spring Festival Evening include Cancer, Ophiuchus and Raven. But these constellations are not easy to identify. Among them, Ophiuchus is regarded as a long snake arrangement. When the snakehead rises due south, the snakehead has not completely crossed the eastern horizon.
