Astronomers, using new imagery from the Hubble space telescope, have found a supermassive black hole at the center of one of the universe's smallest known dwarf galaxies, redefining, calling into question some of our theories about how the universe was formed. The black hole at the center of the dwarf galaxy is about four times larger than the black hole that our own Milky Way revolves around -- but amazingly, the dwarf galaxy is five hundred times smaller than the Milky Way, with a diameter of just 300 light years.
