The study of space is called astronomy. Astronomy is a branch of science that deals with the celestial objects, space, and the universe as a whole. It involves observing and understanding everything from planets and stars to galaxies and cosmic phenomena.
Astronomers use various tools, such as telescopes and satellites, to collect data about these objects and their movements. By studying space, astronomers can learn about the origins of the universe, the life cycles of stars, the formation of planets, and much more. This field not only expands our knowledge of the cosmos but also deepens our understanding of our own planet and the fundamental laws of physics.
