Spring starry sky in four seasons

The main constellations in the sky in spring are Ursa major, Ursa minor, Leo, Capricorn, Canis major, Virgo and Ursa major.

In the direction slightly northeast of the zenith, you can see the connection between the Big Dipper and Doukou, pointing to Polaris. At this time, bucket handle is pointing to the East, so there is a cloud: 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 all over the world.

And along the direction of bucket handle, you can find a bright star, namely arcturus in Capricorn, and then you can reach the main star of Virgo, Cape. Near Ursa major, you can find a small constellation called Canis major. In this small constellation, there is a spiral nebula, M5 1, which is a famous extragalactic galaxy.

Virgo is regarded as the god in charge of agriculture. It is a four-star crow's nest, located in the southwest of its main star, Bumblebee. Below the crow's nest is the tail of Ophiuchus, which spans half the sky from east to west and is one of the largest constellations in the whole day.

The head of the long snake is the famous Leo in the northeast. It is the brightest center of the starry sky on a spring night. The main star of Leo, whose Chinese name is Xuanyuan XIV, is the first-class star on the ecliptic. Sometimes when a bright planet approaches, it is very beautiful.

The most prominent starry sky in spring is the Spring Triangle. Spring triangle refers to three bright stars hanging high in the spring sky, arranged in a triangle. The three bright stars are Emperor I of Leo, Arcturus I of Virgo and arcturus of Patriarch. In addition, the big spring triangle and cor caroli in the dog constellation are arranged in a side rhombus, which is called the big spring rhombus. Using the bucket handle of the Big Dipper, you can find Bighorn and Bumblebee-1 along the arc. This curve is called "Daquan Curve", and then based on these two stars, you can find the Daquan Triangle.

China's ancient Spring Festival travel rush astrology is summed up in four sentences: "The lion roars, the Milky Way returns home, and the two horns guard the East." What exactly do these four sentences mean? Astronomical experts explained this. Zhao Zhi Heng, director of Tianjin Astronomical Society, said that "ginseng" means Betelgeuse, or Orion, which is located in the western sky. "Dou" refers to Beidou, which gradually turns up from the northeast corner. "Epiphany" means that Orion has crossed the western sky and is about to sink, and the Big Dipper rises day by day, indicating the departure of spring and the arrival of summer. Leo is one of the most magnificent constellations in spring. At present, in the south of the sky, the head faces west and the tail faces east, dominating the sky. The six stars in the west are like a reverse question mark, forming a lion's head, and the three stars in the east are like a triangle, forming a lion's tail. Rhetorical questions are connected to triangles like a big lion. "The Milky Way goes home" means that on a spring night, you can't see the Milky Way in the starry sky. Because when Leo rose into the sky, the Milky Way was sinking on the horizon, and people couldn't see it in the sky, so it was said to be "home". As time goes by, the Milky Way will rise from the eastern horizon, and cowherd and weaver girl will also appear on both sides of the Milky Way. At that time, hot summer followed. "Double-horned East Guard" refers to two bright stars in the East, one is arcturus in Capricorn and the other is arcturus in Virgo. The names of the two stars are marked with the word "horn". They are the stars on the two corners of the "Oriental Black Dragon".
