Illustration of an active quasar in a galaxy. The quasar is emitting from the centre of a spiral galaxy. The quasar is powered by material falling into the supermassive blackhole at the centre of the galaxy. This produces high energy radiation which pushes material away from the centre of the galaxy. This quasar wind propels material into the surrounding gas and dust of the galaxy which heats up, shown in blue in the spiral arms. | |
