Astrophysics is the branch of astronomy that applies the laws of physics and mathematics to understand the nature, behavior, and origins of celestial objects and the universe itself. It investigates the physical processes governing stars, planets, galaxies, black holes, dark matter, and dark energy—seeking to explain how cosmic structures form, evolve, and interact. Through observations across the electromagnetic spectrum and data from powerful telescopes and space observatories, astrophysics explores phenomena such as stellar evolution, cosmic radiation, gravitational waves, and the expansion of the universe. This field lies at the heart of modern space science, connecting fundamental physics with the mysteries of the cosmos.
