Great Attractor
The Great Attractor is a concentration of mass hidden behind the Milky Way in the Hydra-Centaurus region, whose gravity draws nearby galaxies, including our own Local Group.
Hydra–Centaurus Supercluster
The Hydra–Centaurus Supercluster, or Hydra–Centaurus concentration, is a nearby complex of galaxy clusters in the southern sky that supplies much of the mass of the Great Attractor.
Laniakea Supercluster
Laniakea Supercluster, the supercluster of galaxies containing the Milky Way, was defined in 2014 as the region where galaxy motions flow toward a common gravitational center.
Ophiuchus Supercluster
The Ophiuchus Supercluster is a large concentration of galaxies behind the Galactic Bulge, centered on the Ophiuchus galaxy cluster about 390 million light-years away, known for the most powerful AGN outburst recorded in any cluster.
Supercluster
A supercluster is one of the largest known assemblies of galaxies, a chain or sheet of clusters and filaments spanning tens to hundreds of millions of light-years.
Virgo Supercluster
The Virgo Supercluster, also called the Local Supercluster, is the large flattened assemblage of galaxy groups and clusters containing the Milky Way's Local Group, centered on the Virgo Cluster.
