Two record-breaking supermassive black holes have been discovered. NGC 3842 has a mass equal to about 9.7 billion Suns. The other, NGC 4889, is thought to have the mass of about 20 billion Suns, but could be as large as 37 billion Suns. The estimates vary, but they are truly gigantic monsters. To get an idea of how large these things are, our entire solar system would be greatly dwarfed by them.
