More Images of Perseus A


1
Smoothed X-ray image of the Perseus cluster
The colors represent variations in the intensity­ not temperature-- 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.

Scale: Image is 6 arcmin ( 600,000 light years) on a side.

Optical image of Perseus A (NGC 1275)
The large central galaxy in the Perseus cluster. The infalling galaxy is the irregular shape at two o'clock.

Scale: Image is 150 arcsec (240,000 light years) on a side.

Radio Image of Perseus A
Very Large Array radio image (contours) overlaid on Chandra X-ray image of Perseus cluster. The colors represent intensity of X-rays, with red being the brightest and blue the faintest.

Scale: as shown: (1 kpc = 3,260 light years)
