The object, located at the center of the dwarf galaxy NGC 4395, is around 10,000 times the mass of the sun, the researchers determined.

Although astronomers believe that every galaxy the size of or larger than the Milky Way harbors a supermassive black hole at its center, researchers don't know a lot about the black holes of smaller galaxies — or whether black holes even exist in all galaxies.

"Do these galaxies have black holes, and if they do, do they scale the same way as supermassive black holes?" Elena Gallo, an astronomy professor at the University of Michigan and lead author of the study,...
