Illustration of a distant galaxy with an active quasar at its center. Quasars are extremely remote celestial objects, emitting exceptionally large amounts of energy. As a supermassive black hole at the center of the galaxy devours matter, hot gas encircles it and emits intense radiation, creating the quasar. 'Quasar winds', driven by radiation pressure from the vicinity of the black hole, push material away from the galaxy's center at a fraction of the speed of light.
