Location of constellation: On summer nights, you can find Sagittarius from Altair in the eagle along the south side of the Milky Way. Because the galactic center is in the direction of Sagittarius, this part of the galaxy is the widest and brightest.

Sagittarius is facing the center of the Milky Way, so there are many clusters and nebulae in it. Where the connecting line between σ and λ in Nandou doubles to the west, you can see a small cloud-like thing, which is actually a nebula. In the telescope, it is composed of three red dots, which is very beautiful and is called "trifid nebula".

Sagittarius has many nebulae. For example, there is a horseshoe-shaped nebula in the north of bucket handle μ star in Nandou, so it is called "horseshoe nebula".

Twelve constellations in the eyes of scientists:

Because the earth revolves around the sun, when people look at the sun from the earth's mobile platform, it is the sun that revolves around the earth relatively-the sun moves slowly on the starry background, only once a year, and returns to its original position. The route that the sun "walks" in this way is called the ecliptic.

Moreover, the orbit of the moon around the earth, that is, the "white road", and the orbit of planets around the sun is very close to the ecliptic, so the moon and planets always "shuttle" back and forth not far from the ecliptic, so that the ecliptic region has become a "runway" for celestial bodies such as the sun, the moon and the planets to chase and meet each other.

Babylonians paid special attention to this phenomenon more than 3000 years ago, so they drew a wide road along the ecliptic-the so-called "Zodiac". Its width extends to 8 degrees on both sides of the ecliptic, totaling 16 degrees. The zodiac signs were first marked by the zodiac signs, with an average score of 12, which is called "zodiac signs".
