Abell2151 Galaxy-Cluster in Hercules

Abell2151 is one of the richstest and biggest galaxy-clusters known today.Its distance in the constellation of Hercules measures about 500 mio.light-years and extends about twice as wide as the field in the picture below.

You can find among the 100 cluster-members many spiral- and interacting galaxies.The brightest member is NGC 6041A,which itself interacts strongly with its compagnion NGC6041B.

A2151 is part of the large Hercules Supercluster,which itself belongs to the much larger super-structure called the Great Wall.

The cluster was first described by H.Shapley in 1933.
