The Hercules Superclusters (SCl 160) refers to a set of two nearby supercluster

Superclusters are large groups of smaller galaxy groups and clusters and are among the largest known structures of the cosmos. They are so large that they are not gravitationally bound and, consequently, partake in the Hubble expansion.-Existence:...

s of galaxies.

Relative to other local superclusters, Hercules is considered particularly large, being approximately 330 Mly in diameter. There is a vast cosmic void in front of the region that is as big as the superclusters themselves.

The region includes the Abell 2147

Abell 2147 is a galaxy cluster in the Abell catalogue. It is located within the core of the Hercules Superclusters, within Serpens Caput, approximately two degrees south southwest of the Hercules Cluster...

, A2151, and A2152 galaxy clusters. An extremely long filament of galaxies has been found, that connects this group of clusters to the Abel A2197 and A2199 pair.

The Hercules Superclusters are near the Coma Supercluster

The Coma Supercluster is a nearby supercluster of galaxies comprising the Coma Cluster and the Leo Cluster . Located 300 million light-years from Earth, it is in the center of the Great Wall. The Coma Supercluster is the nearest massive cluster of galaxies to our own Virgo Supercluster...
