Astronomy occupies a very important position in the history of early human civilization, because it is of great significance to guiding agricultural production. Astronomy is a subject that mainly observes and explains the material conditions and events of celestial bodies and collects all kinds of information of celestial bodies through observation. However, because a large number of data can not be measured directly, it needs to be derived indirectly through mathematical calculus (such as the distance between the sun and the earth), which promotes the development of mathematics. Logarithm, spherical coordinate system and trigonometric function are all derived from astronomical research. On the other hand, astronomy needs more and more observation tools, and the production of these tools also needs superb knowledge of mathematics, physics and chemistry. After Newton described the macroscopic world with classical mechanics system and mathematical language, the relationship between mathematics and astronomy became closer and closer, and non-Euclidean geometry and calculus developed rapidly under the demand of astronomy (of course, mathematics has become an indispensable tool for various natural sciences in this period, and this kind of knowledge has been widely used.

For a small example, the landlord may know that the FAST radio telescope being built in China is invisible to the naked eye, and it is a lot of curved curves after computer processing. Astronomers must analyze through their own knowledge of mathematics, physics and even chemistry to explore the astronomical significance behind it. It can be seen that modern astronomy is the latest knowledge of physics, chemistry and mathematics, and the most advanced scientific and technological means mastered by mankind. Stars, planets, galaxies and other images in the universe.
