. Similar to an optical lens bending light to form an image, the galaxy cluster Abell 2218 is so massive and compact that light rays passing through it are deflected by its enormous gravitational field. This process (called gravitational lensing) magnifies, brightens, and distorts images of objects that lie far beyond the cluster. The thin arcs are distorted images of distant galaxies roughly 5-10 times farther than the cluster. A. Fruchter / STScI / NASA
