The massive cluster of galaxies Abell 1689 as seen by Hubble's Advanced Camera for Surveys.

The cluster's gravity acts as a gravitational lens, bending and magnifying the light of galaxies located far behind it. The faraway galaxies appear in the Hubble image as arc-shaped objects around the cluster. The increased magnification allows astronomers to study remote galaxies in greater detail.
