The
colors represent variations in the intensity not of temperature, but
of the X rays, with white being the most intense, to red being the least.
The red and orange show X-ray emitting gas in the cluster. The more intense
yellow and white regions are in and around the supergiant galaxy, Perseus
A. |

colors represent variations in the intensity not of temperature but
of the X rays, with white being the most intense, to red being the least.
The red and orange show X-ray emitting gas in the cluster. The more intense
yellow and white regions are in and around the supergiant galaxy, Perseus
A. A small dark patch located at two o'clock from the center of the image
is a galaxy with "only" about 20 billion stars that is falling
into Perseus A. Another larger hole seen further out is thought to be due
to a bubble of high energy particles ejected in an explosion from Perseus
A hundreds of millions of years ago. The central region is discussed at
Perseus A Photo Album. |
