Acting as a «natural telescope» in space, the gravity of the extremely massive foreground galaxy cluster MACS J2129 - 0741 magnifies, brightens, and distorts the far - distant background galaxy MACS2129 - 1, shown in the top box.

Foreground galaxy clusters can warp and magnify the light of distant, background proto - galaxies, for instance, allowing cosmologists to catch glimpses of early epochs of the universe.

Except for a few blue, foreground stars, the stars are part of the Milky Way's nuclear star cluster, the most massive and densest star cluster in our galaxy.

This «gravitational lens» magnifies galaxies behind the cluster, making them appear far brighter than they would if the foreground cluster of galaxies were not there.

Some of these galaxies may be foreground or background galaxies in the vicinity of the cluster.

It is impossible to get a good photograph of the entire cluster because the galaxies are faint objects scattered across 15 degrees of the sky, and a large angle photograph would be swamped by thousands of foreground stars in our own galaxy.
