Hydra-Centaurus Supercluster
Lua error in Module:Infobox at line 235: malformed pattern (missing ']'). The Hydra-Centaurus Supercluster (SCl 128), or the Hydra and Centaurus Superclusters, is a supercluster in two parts and the closest neighbour of Virgo Supercluster.
Hydra-Centaurus
The cluster includes four large galaxy clusters in the Centaurus part
- Abell 3526 (Centaurus Cluster),
- Abell 3565,
- Abell 3574,
- Abell 3581,
and the proximate
- Hydra Cluster (A1060) and
- Norma Cluster (A3627).
Apart from the central clusters, which are 150 to 200 millions of light years away, several smaller clusters belong to the group.
Within the proximity of this supercluster lies the Great Attractor, dominated by the Norma Cluster (Abell 3627). This massive cluster of galaxies exerts a large gravitational force, causing all matter within 50 Mpc to experience a bulk flow of 600 km/s toward the Norma Cluster[1]
Laniakea
A 2014 announcement says that the Centaurus Supercluster (Hydra-Centaurus) is just a lobe in a greater supercluster, Laniakea, that is centered on the Great Attractor. That supercluster would include the Virgo Supercluster, and be our local supercluster.[2]
