Southern Supercluster Strand
The Southern Supercluster Strand is a galaxy filament that incompasses the Southern Supercluster and the Telescopium−Grus Cloud. In 2014, it was announced that the Southern Supercluster Strand is a lobe in a greater supercluster, Laniakea Supercluster, Laniakea, that is centered on the Great Attractor. This would mean that the Southern Supercluster Strand's components, the Telescopium−Grus Cloud and the Southern Supercluster would be part of this new supercluster. The Virgo Supercluster would also be part of this greater supercluster, thus becoming the local supercluster. Physical characteristics The Southern Supercluster Strand is a galaxy filament that emerges from the Centaurus Cluster. The filament then branches off into two forks, SSCa, and SSCb, also known as the Southern Supercluster and the Telescopium−Grus Cloud respectively. The Southern Supercluster is a long major chain of galaxies, consisting of the major Dorado Group, Dorado, Fornax Cluster, Fornax, and Eri ...

Laniakea Supercluster
The Laniakea Supercluster (; Hawaiian language, Hawaiian for "open skies" or "immense heaven") or the Local Supercluster (LSC or LS) is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies. It was defined in September 2014, when a group of astronomers including R. Brent Tully of the University of Hawaiʻi at Mānoa, University of Hawaiʻi, Hélène Courtois of the University of Lyon, Yehuda Hoffman of the Hebrew University of Jerusalem, and Daniel Pomarède of CEA Université Paris-Saclay published a new way of defining superclusters according to the Radial velocity, relative velocities of galaxies. The new definition of the local supercluster subsumes the prior defined Virgo Supercluster, Virgo and Hydra-Centaurus Supercluster as appendages, the former being the prior defined local supercluster. Follow-up studies suggest that the Laniakea Supercluster is not gravitationally bound. It will disperse rather than continue to maintai ...
