Pisces–Cetus Supercluster Complex(Redirected from Pisces-Cetus Supercluster Complex)
The Pisces–Cetus Supercluster Complex is a galaxy filament. It includes the Virgo Supercluster which in turn contains the Local Group, the galaxy cluster that includes the Milky Way. (However, a 2014 study indicates that the Virgo Supercluster is only a lobe of a greater supercluster, Laniakea.) This filament is adjacent to the Perseus–Pegasus Filament.
The Pisces–Cetus Supercluster Complex is estimated to be about 1.0 billion light-years (Gly) long and 150 million light years (Mly) wide. It is one of the largest structures known in the observable universe, but is exceeded by the Sloan Great Wall (1.3 Gly), Clowes–Campusano LQG (2.0 Gly), U1.11 LQG (2.5 Gly), Huge-LQG (4.0 Gly), and Hercules–Corona Borealis Great Wall (10 Gly), respectively.
- The Pisces-Cetus Supercluster
- The Perseus-Pegasus chain, including the Perseus-Pisces Supercluster
- The Pegasus-Pisces chain
- The Sculptor region, including the Sculptor Supercluster and Hercules Supercluster
- The Laniakea Supercluster, which contains our Virgo Supercluster (Local Supercluster) as well as the Hydra-Centaurus Supercluster.
The complex was named after the Pisces-Cetus Superclusters, which are its richest superclusters.
