Astronomy is the scientific study of celestial objects, space, and the universe as a whole. It encompasses the observation and analysis of planets, stars, galaxies, and cosmic phenomena, as well as the laws that govern these entities. Astronomy seeks to understand the origins, evolution, and behavior of celestial bodies and the underlying physical principles that guide them. It also involves the use of advanced technologies, such as telescopes and spacecraft, to explore and gather data from beyond Earth’s atmosphere. The field of astronomy is divided into several sub-disciplines, including observational astronomy, theoretical astronomy, astrophysics, and cosmology, among others.
