Astrophysics is the branch of astronomy that deals with the physical and chemical properties of celestial objects. Observational astronomy involves observing celestial objects and recording their behavior, while theoretical astronomy involves using mathematical models to understand the behavior of celestial objects. Branches of AstronomyĪstronomy is divided into several branches, including observational astronomy, theoretical astronomy, and astrophysics. In the modern era, astronomy has become a highly technical field that utilizes advanced technology, such as telescopes and spacecraft, to study celestial objects. The ancient Greeks, such as Aristotle and Ptolemy, made significant contributions to the field of astronomy by studying the motion of the planets and stars. The history of astronomy dates back to ancient times, where people observed the night sky and recorded celestial events. It is a field that encompasses various disciplines, such as physics, chemistry, and biology, to understand the behavior and properties of celestial objects. Astronomy is the scientific study of celestial objects, including stars, planets, galaxies, and the universe as a whole.
