"Peering deep into the heart of the Andromeda Galaxy, the Hubble Space Telescope found a pair of bright objects at the center, orbiting the dark monster that is a black hole up to 230 million times heftier than our sun. One of the glowing objects within the center of Andromeda, known as Messier 31 (M31) is thought by astronomers to be a dense and compact star cluster. the other object is a fainter disc-shaped, spiraling hot gas swirling around the gravitational sinkhole of the black hole."
