The black hole at the center of M60-UCD1 has five times the mass of the black hole at the center of the Milky Way. It has the mass of 21 million suns and makes up 15% of the mass of M60-UCD1. The Milky Ways central black hole has the mass of 4 million suns and makes up less than .01% of the Milky Ways total mass. The M60-UCD1 galaxy has an amazing amount of stars. NASA says if you lived inside M60-UCD1 you could see at least 1 million stars with the naked eye. On Earth you can see only about 4,000 stars with the naked eye. The astronomers believe the discovery of the supermassive black hole at the center of a tiny galaxy means that dwarf galaxies could be stripped remnants of galaxies that were once much larger. University of Utah astronomer Anil Seth, lead author of the M60-UCD1 study published in Nature, says, We dont know of any other way you could make a black hole so big in an object this small. There are a lot of similar ultracompact dwarf galaxies, and together they may contain as many supermassive black holes as there are at the centers of normal galaxies.
