It seems that most galaxies have a supermassive black hole in their center. These supermassive black holes have a mass that is millions of times the mass of our Sun; in larger galaxies, billions of times the mass of our Sun. Hence the name "supermassive". For comparison, when a star collapses, it is expected to produce a black hole that has less mass than the star originally had (some mass goes into space, in the supernova explosion), in other words, a few solar masses, or a few tens of them, at most.
