[edit]DescriptionM31- Chandra Images Heart of Andromeda Galaxy (2000-0007).pdf |
English: [Please note: Additional observations of M31 that alter the conclusions in this release were announced on October 12, 2001. View the updated Chandra results on the Andromeda galaxy.] This Chandra X-ray image shows the central portion of the Andromeda Galaxy. The blue dot in the center of the image is an unusually "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. |
