The study of the stars and celestial bodies is called astronomy. Astronomy is a branch of science that focuses on the observation, analysis, and understanding of celestial phenomena, including stars, planets, moons, galaxies, and the universe as a whole. Researchers in this field use telescopes and other instruments to gather data and explore the origins, evolution, and behavior of celestial objects. Astronomy not only provides insights into the cosmos but also leads to advancements in physics, mathematics, and technology, enriching our understanding of the universe and our place within it.
