This optical image of the Andromeda Galaxy (M31) shows the beautiful spiral structure of a spiral galaxy.

Summary

Description	English: This optical image of the Andromeda Galaxy (M31) shows the beautiful spiral structure of a spiral galaxy. M31 is our nearest neighbor spiral galaxy (outside of the Milky Way), and therefore offers us a view of what the Milky Way might look like if we could travel from our current location in the middle of a Milky Way spiral arm to a point high above our galaxy. The black square in the center shows the size of the nuclear region imaged by Chandra.

Short title	Chandra Images Heart of Andromeda Galaxy
Image title	This X-ray image shows the central portion of the Andromeda Galaxy. The blue dot in the center of the image is an unusual "cool" million degree X-ray source of unknown nature. Just above this cool source is a source (yellow) that is thought to be due to X-rays from matter swirling toward a supermassive black hole in the nucleus of the galaxy. This black hole contains the mass of 30 million suns. Numerous other X-ray sources are also apparent. Most of these are probably due to X-ray binary systems, in which a neutron star or black hole is in a close orbit around a normal star.
