Andromeda Galaxy core stars, artwork. This disk of young, blue stars is thought to be orbiting a supermassive black hole at the core of the Andromeda Galaxy (M31). The background stars are the older, redder population of stars typical found in galactic cores. Observations by the Hubble Space Telescope (HST) indicate that 400 of these young blue stars formed about 200 million years ago, forming a disk that is only one light year across, with orbital speeds of 1000 kilometres a second. Artwork published in 2005.
