Astronomy is a science discipline. Astronomy is the discipline of observing and studying celestial bodies in the universe. It studies the distribution, movement, position, state, structure, composition, nature, origin and evolution of celestial bodies. It is a basic discipline in natural science.
Among the subordinate disciplines of astronomy, only the history of astronomy can be regarded as a discipline of partial literature. Other disciplines, whether they are doing observation, science popularization or theoretical research, are all science subjects.
In universities, astronomy mainly focuses on basic subjects such as physics, mathematics (English computer) and astronomy. In a few universities that offer astronomy, it is generally positioned as one of the basic subjects of science or a branch of physics.
One notable difference between astronomy and other natural sciences is that the experimental method of astronomy is observation, through which various information about celestial bodies is collected. Therefore, the study of observation methods and means is a direction that astronomers strive to study.
In ancient times, astronomy was also inseparable from the formulation of the calendar. Modern astronomy has developed into the science of observing all electromagnetic wave bands.
Astronomy plays an irreplaceable role in the success of all kinds of space exploration. Astronomy has also made its own contribution to disaster prevention and reduction for mankind and the earth.
