| Andromeda Galaxy: composite x-ray/optical zoom of nucleus | |||
|
This
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!
