The study of celestial bodies and their movements is called astronomy. This scientific discipline involves the observation and analysis of stars, planets, comets, galaxies, and other celestial phenomena, aiming to understand their formation, evolution, and behavior. Astronomy combines principles from physics, mathematics, and chemistry to explore the universe's vastness and the laws governing celestial mechanics. It has played a crucial role in shaping human understanding of our place in the cosmos, leading to significant discoveries about the origins of the universe and celestial phenomena like black holes and supernovae.
