Astronomy and astrophysics are two closely related fields of science that study the universe, its components, and the underlying principles governing celestial phenomena. **Astronomy** is the broad study of celestial objects, space, and the universe as a whole. It involves the observation and analysis of planets, stars, galaxies, and other astronomical phenomena. Astronomers often use telescopes and other instruments to gather data about these objects and attempt to understand their properties, behaviors, and the origins of the universe.
