What are the main stars in the night sky in spring?

How to look at the stars on a spring night?

It is spring from March to May every year, and the most striking thing in spring night is Ursa Major in the northern sky. It is mainly composed of seven bright stars, shaped like a spoon, just like an ancient wine container, so it is called the Big Dipper, also known as the Big Dipper. Among them, four stars make up a bucket spoon, and three stars make up the bucket handle. The position of the Big Dipper in the northern sky is different in different seasons and at different times, so we can judge the seasons according to the position of the Big Dipper. China's ancient book "Goose Bird Tube" has: "bucket handle refers to the east, and the world is spring; Bucket handle guide, the world is summer; Bucket handle refers to the west, and the world is autumn; Bucket handle refers to the north, and it is winter in the world. " . At dusk in spring, the bucket handle of the Big Dipper points to the east.

To the south of the Big Dipper is Leo. Its head faces west, and it is composed of several bright stars, and it is curved and sickle-shaped. The brightest star is called Xuanyuan XIV, which emits blue and white light. The lion's tail is in the east. It is mainly composed of three stars in a triangle. To the west of Leo is Cancer, whose image is imagined as a big crab. In this constellation, you can directly see a dim light spot with your eyes, called the hive cluster. On the lower left of Leo is Virgo, and its brightest star is Capricorn. Cancer, Leo and Virgo are all zodiac signs. Between Xuanyuan XIV and Jiaokou, it is one of the intersections of the autumnal equinox, ecliptic and celestial equator. Every year around September 23, the sun seems to run on the ecliptic and pass through this celestial body area. Below Virgo is a parallelogram composed of four stars, which belongs to corvus corax. Below the crow is Ophiuchus, which spans things. Naturally extending from the bucket handle of the Big Dipper, we will see a bright star, which is arcturus, the bright star of Capricorn and the brightest star in the northern hemisphere. Between Leo and Capricorn, there is a late constellation. This constellation is very small, and there are no bright stars, but this small constellation is very famous: first, the North Silver Pole is in this constellation, and second, this region contains many celestial systems at the galaxy level, and their secrets can only be revealed through large astronomical telescopes.
