Quasars and Black holes

Quasars are incredibly bright and distant celestial objects powered by supermassive black holes at the centers of galaxies. As matter spirals into the black hole, it heats up due to intense gravitational forces, emitting vast amounts of energy, including X-rays and radio waves. This process makes quasars some of the universe's most luminous entities, often outshining their host galaxies. Black holes themselves are regions in space where gravity is so strong that nothing can escape from them, not even light. Both quasars and black holes are key to understanding high-energy processes and the evolution of galaxies in the universe.
