Astronomy is the scientific study of celestial bodies, such as stars, planets, comets, and galaxies, as well as the universe as a whole. It encompasses the observation and analysis of these objects and phenomena, aiming to understand their origins, evolution, composition, and eventual fate. Astronomy utilizes principles from physics and mathematics to explore topics like the nature of light and gravitational forces, aiding in the formulation of theories regarding the cosmos. The discipline includes various subfields, such as astrophysics, planetary science, and cosmology, each focusing on specific aspects of the universe. Through telescopes and other instruments, astronomers gather data to interpret the structure and dynamics of the universe, contributing to our knowledge of fundamental questions about existence and the laws governing the natural world.
