Infrared image of the galaxy Abell 2667

This infrared image was taken by NASA's Spitzer Space Telescope and shows a part of the galaxy cluster Abell 2667.

The 'Comet Galaxy' is the bright red object seen to the left of the cluster centre. Also seen in the image is a rare giant infrared arc. The banana-shaped arc corresponds to the magnified and distorted image of a distant galaxy that lies behind the cluster’s core.
