Astrophysics is the study of the physical properties and behavior of celestial objects and phenomena throughout the universe. It applies the laws of physics and mathematics to understand how stars, planets, galaxies, and cosmic structures form, evolve, and interact. By analyzing light, radiation, and other signals from space, astrophysicists explore fundamental questions about the origins of the universe, the nature of black holes and dark matter, and the potential for life beyond Earth. The field bridges observation and theory, combining data from telescopes with advanced computational models to uncover the workings of the cosmos.
