The Perseus–Pisces Supercluster is one of two dominant concentrations of galaxies (the other being the Local supercluster) in the nearby universe (within 300 million light years). This supercluster also borders a prominent void, the Taurus Void, and is part of the Perseus–Pegasus Filament which stretches for roughly a billion light years. [1]
Perseus–Pegasus Filament (1985) 1,000,000,000: This galaxy filament contains the Perseus–Pisces Supercluster. Pisces–Cetus Supercluster Complex (1987) 1,000,000,000: Contains the Milky Way, and is the first galaxy filament to be discovered. (The first LQG was found earlier in 1982.) A new report in 2014 confirms the Milky Way as a member ...

It consisted of two known rich clusters and one newly discovered cluster as a result of the study that discovered it. The then known clusters were Cl 1604+4304 (z=0.897) and Cl 1604+4321 (z=0.924), which then known to have 21 and 42 known galaxies respectively. The then newly discovered cluster was located at 16 h 04 m 25.7 s, +43° 14′ 44.7 ...
The Perseus–Pegasus Filament is a galaxy filament containing the Perseus–Pisces Supercluster and stretching for roughly a billion light-years (or over 300/h Mpc). Currently, it is considered to be one of the largest known structures in the universe. [note 1] This filament is adjacent to the Pisces–Cetus Supercluster Complex.
NGC 1272 is a massive [2] elliptical galaxy [3] located about 230 million light-years away [4] in the constellation Perseus. [5] It was discovered by astronomer Heinrich d'Arrest on February 14, 1863. [6] NGC 1272 has an active nucleus and is the second brightest [2] member of the Perseus Cluster [7] [6] after NGC 1275.

NGC 1193 is an open cluster in the Perseus constellation. [1] It was first observed and catalogued by astronomer William Herschel in 1786. [ 3 ] The cluster is estimated to be approximately 4.2 billion years old.
NGC 1279 is a lenticular galaxy estimated to be 324 million light-years away from the Milky Way [3] in the constellation Perseus. [4] It has diameter of about 110,000 ly, [3] and is a member of the Perseus Cluster. [5] [6] It was discovered on December 12, 1876, by astronomer John Louis Emil Dreyer. [6]
