Astrophysics

Astrophysics is the branch of astronomy that applies the principles of physics and chemistry to understand how stars, galaxies, planets, and the universe behave. It involves the study of the properties and interactions of celestial objects and phenomena, including their composition, temperature, motion, and evolution. Astrophysicists seek to explain the underlying physical processes that govern the formation, evolution, and eventual fate of these astronomical entities, often using mathematical models and observations from telescopes and other instruments. Key topics within astrophysics include the life cycles of stars, the nature of black holes, dark matter and dark energy, cosmic microwave background radiation, and the dynamics of galaxies and the universe as a whole.
