The starry sky is enchanting and mesmerizing. Each season has a different starry sky and also has its own representative constellation, do you know which is the representative constellation of the spring starry sky?
This is the well-known Leo. Leo is not difficult to find, Beijing astronomy enthusiast Wang Junfeng introduced, first of all to find the Big Dipper seven stars, from the Doukou in turn to: Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang and Shake Light. Extending from the Celestial Hub to the direction of Tianxuan, about seven times the distance between these two stars, is the constellation Leo.

In spring, Leo rises in the east at nightfall, between Virgo and Cancer. Of the 88 constellations throughout the day, Leo ranks 12th in terms of area. Every year around the night of March 1, the center of Leo hangs high in the middle of the ceiling.

Leo is a bright constellation that is easily recognizable in the spring starry sky. Among them, six stars, such as Regulus XIV, Regulus XIII, and Regulus XII, form a "sickle" (or "question mark") structure, which represents the head, neck and mane part of the lion.

Regulus XIV is the first bright star in the constellation Leo and is a blue-white star that symbolizes the heart of the lion. It, along with Aldebata in Taurus, also near the ecliptic, Scorpio's Heart Ii, and The North Gate in the constellation Officus, is known as the "Four Kings" of the zodiac.
The first of the five emperors is the second brightest star in the constellation Leo, a white star and a variable star, forming an equilateral triangle with the Arcturus star of The Oberoptera and the Horn of Virgo, called the "Spring Triangle". And these three stars and The Constant Chen Yi of the constellation Canis form the "Spring Diamond".

Since Leo is mentioned, it is inevitable that the Leo meteor shower, known as the "king of the meteor shower", must be indispensable. The Leo meteor showers of 1998, 1999 and 2001 left a deep impression on many.

"It should be noted that the famous Leo meteor shower is not due to Leo. The meteor shower is formed by the material thrown by a comet called Temple Tuttle as it streaks across the atmosphere. Because the projection of the direction that forms the meteor shower on the celestial sphere coincides with leo's projection on the celestial sphere, it looks as if the meteor shower is ejected from Leo on Earth, so it is called the Leo meteor shower. Wang Junfeng said.

Spring returns to the earth, the weather is getting warmer, and it is time to enjoy the stars. Pick a good weather, meet three or five friends, put on the equipment, go to a "romantic date" with the spring starry sky, and look for the traces of the "male lion".
