Royalty-free NASA stock photo of two different kinds of galaxies, those with plump middles/central bulges (upper left), and those lacking the bulge (foreground). The slender, bulgeless galaxies can, like their chubbier counterparts, harbor supermassive black holes at their cores. Previously, astronomers thought that a galaxy without a bulge could not have a supermassive black hole. In this illustration, jets shooting away from the black holes are depicted as thin streams.
