Image: Most remote mature cluster

Description: This image is a composite of very long exposures taken with ESO’s Very Large Telescope in Chile and the NAOJ’s Subaru telescope on Hawaii. Most of the visible objects are very faint and distant galaxies. The clump of faint red objects to the right of centre is the most remote mature cluster of galaxies yet found.
