Release date: Jan 11, 2012 10:45 AM (EST)
Release type: American Astronomical Society Meeting

A new Hubble Space Telescope image centers on the 100-million-solar-mass black hole at the hub of the neighboring spiral galaxy M31, or the Andromeda galaxy, one of the few galaxies outside the Milky Way visible to the naked eye and the only other giant galaxy in the Local Group. This is the sharpest visible-light image ever made of the nucleus of an external galaxy.

The Hubble image is being presented today at the meeting of the American Astronomical Society in Austin, Texas.
