In today's image, we see Centaurus, an example of an active galaxy. In this galaxy, there are actually two galaxies, a spiral galaxy and an elliptical which are in the process of colliding. The material involved in the collision, along with a supermassive black hole at the center of the galaxy are responsible for the excess energy being released.
