Astronomy is always the forerunner of philosophy. It is always at the forefront of the debate. As a basic research discipline, astronomy is closely related to human society in many aspects. The strict laws of time, the alternation of day and night and the change of the four seasons must be determined by astronomical methods. Mankind has entered the space age, and astronomy plays an irreplaceable role in the success of all kinds of space exploration.

Astronomy also makes its own contribution to disaster prevention and reduction for mankind and the earth. Astronomers will also pay close attention to catastrophic astronomical events, such as the possible collision between comets and the earth, make timely prevention and make corresponding countermeasures.
