Notes

Abell 2151 (also called The Hercules Cluster) is a cluster of about 200 galaxies at a distance of about 500 million light-years in the constellation Hercules. The cluster is part of the larger Hercules Supercluster, which is itself part of the much larger Great Wall super-structure.

The Hercules Cluster contains many spiral galaxies, a smaller number of elliptical galaxies and shows many interacting galaxies. This image clearly shows the star forming galaxies with a blue tint and galaxies with older stellar populations with a yellowish cast.
