Arc in Visible light (Hubble)

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. The increased magnification allows astronomers to study remote galaxies in greater detail.

One galaxy is so far away, however, it does not show up in this visible-light image taken with Hubble's Advanced Camera for Surveys.
