Summary

[edit]
Description
English: X-ray/Optical Composite This composite shows the optical image of M31 with an inset consisting of the Chandra X-ray image of the nucleus. An approximate temperature scale is also shown for the X-ray image. In order to emit X-rays, gas must be very hot: hotter than a million degrees Centigrade. The gas falling into the super massive black hole in the nucleus of M31 is cool only by comparison to the other X-ray emitting stars and black holes nearby: They are typically 20 million degrees!
