ZwCl 1358+62 is located 3.7 billion light-years from Earth (z=0.33) and is made up of at least 150 individual galaxies. This image depicts multiple blue, red and orange arcs scattered across the image, which represent amplified and stretched images of the galaxies behind the cluster's core. The colours displayed by the various lensed galaxies vary according to their distance and galaxy types. The natural gravitational lensing effect in combination with Hubble's potent mirrors provide astronomers with a powerful set of tools to gather information on the nature of distant galaxies and the workings of the "hidden" world around us.
