Abell 1689

The gravity of the cluster's trillion stars acts as a cosmic "zoom lens", bending and magnifying the light of the galaxies located far behind it, a technique called gravitational lensing. The faraway galaxies appear in the Hubble image as arc-shaped objects around the cluster, named Abell 1689, seen in this image. The increased magnification allows astronomers to study remote galaxies in greater detail.
