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 center. 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.
