Astrophysical objects are celestial bodies that exist in outer space and are studied by astrophysicists. These objects include stars, planets, asteroids, comets, galaxies, nebulae, and black holes, among others. Astrophysical objects are typically studied to gain a better understanding of the universe and its many phenomena, such as the formation and evolution of galaxies, the life cycles of stars, and the behavior of matter under extreme conditions. Researchers use a variety of methods, including telescopes, space probes, and computer simulations, to study these objects and unlock the mysteries of the cosmos.
