@holvek: A quasar is one of the brightest and most powerful objects in the Universe. Initially, they appeared to be stars, but in reality they are the active cores of distant galaxies. At their center lies a supermassive black hole that attracts surrounding matter, forming an accretion disk. As this matter heats up, it emits enormous amounts of energy across the entire electromagnetic spectrum—from visible light to X-rays and radio waves—allowing quasars to outshine entire galaxies. They are often accompanied by jets, streams of matter ejected at nearly the speed of light. Due to their immense distance, quasars help scientists study the early Universe and the evolution of black holes and galaxies. #blackhole #scary #quasar #fact
