Galactic nuclei

Galactic nuclei are the central regions of galaxies, often hosting supermassive black holes that can be millions or billions of times more massive than the Sun. These areas are densely packed with stars, gas, and dust, and can produce intense radiation and energetic phenomena. Some galactic nuclei are active, emitting large amounts of energy as matter falls into the black hole, creating what are called active galactic nuclei or quasars. These regions are key to understanding galaxy formation and evolution, serving as cosmic centers that influence their entire galaxy’s structure and activity.
