Hercules Superclusters

The Hercules Superclusters (SCl 160) refers to a set of two nearby superclusters of galaxies.[1]

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.[2]

The region includes the Abell 2147, A2151, and A2152 galaxy clusters.[3][4] An extremely long filament of galaxies has been found, that connects this group of clusters to the Abel A2197 and A2199 pair.[4]

The Hercules Superclusters are near the Coma Supercluster, helping make up part of the CfA2 Great Wall.[5]
