Astrophysics is a branch of science that studies the physical and chemical properties of objects and phenomena in space, such as stars, planets, galaxies, and black holes. It helps us understand the origin, evolution, and behavior of the universe. The word 'astrophysics' can be used in many different contexts, such as when talking about space exploration, astronomy, or studying the natural world. For example, someone may say, "I am very interested in astrophysics and want to become an astrophysicist someday."
