The study of stars and celestial objects is known as astronomy. It encompasses the observation and analysis of celestial phenomena, including planets, stars, galaxies, and the universe as a whole. Astronomers use various tools and technologies, such as telescopes, to study these objects, aiming to understand their origins, evolution, and the fundamental laws that govern them. This field not only contributes to our understanding of the cosmos but also enhances our knowledge of Earth and our place within the universe.
