Info
Galaxy Cluster Abell 2218 is a massive cluster of galaxies
some 2 billion light years distant toward the constellation Draco. Galaxy
cluster Abell 2218 is so massive that its gravitational field can deflect rays
of light that pass through it. This "gravitational lensing" effect serves to
magnify, distort, and brighten the light of distant galaxies that by chance
happen to lie behind the cluster, which in the image are visible as thin arc
segments.
