Astronomers have discovered an enormous black hole at the center of the NGC 1277 disk galaxy. The enormous black hole at NGC 1277's center has the mass of 17 billion times the mass of the sun, which could make it the most massive black hole found to date. While most galaxies likely have black holes in their center ( even our Milky Way), what is very unusual about the black hole in NGC 1277 is not only its large mass, but the fact that it makes up about 14% of NGC 1277's total mass. Astronomers only expect a black hole to make up about 0.1% the total mass of a galaxy.
