... STScI-PF95-14 FOR RELEASE: APRIL 5, 1995 HUBBLE VIEWS DISTANT GALAXIES THROUGH A COSMIC LENS This NASA Hubble Space Telescope image of the rich galaxy cluster, Abell 2218, is a spectacular example of gravitational lensing. The arc-like pattern spread across the picture like a spider web is an illusion caused by the gravitational field of the cluster. ... The arcs are the distorted images of a very distant galaxy population extending 5-10 times farther than the lensing cluster. ...
