Astronomy is the scientific study of celestial objects, space, and the universe as a whole. It involves the observation and analysis of stars, planets, moons, comets, galaxies, and the cosmos. Astronomers seek to understand the origin, evolution, and eventual fate of these entities, as well as the physical laws governing their behavior and interactions. The discipline encompasses various subfields, including observational and theoretical astronomy, astrophysics, cosmology, and planetary science. Astronomy relies on a range of tools and techniques, such as telescopes and satellite instruments, to gather data and test hypotheses about the nature of the universe.
