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]
The Perseus cluster (Abell 426) is a cluster of galaxies in the constellation Perseus. It has a recession speed of 5,366 km/ s and a diameter of 863 ′ . [ 1 ] It is one of the most massive objects in the known universe , containing thousands of galaxies immersed in a vast cloud of multimillion-degree gas.
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 ...
NGC 1275 (also known as Perseus A or Caldwell 24) is a type 1.5 Seyfert galaxy [3] located around 237 million light-years away [2] in the direction of the constellation Perseus. NGC 1275 is a member of the large Perseus Cluster of galaxies.

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.
Other notable features in Perseus include X Persei (a binary system containing a neutron star), GK Persei (a nova that peaked at magnitude 0.2 in 1901), the Double Cluster (comprised of two open clusters near each other in the sky), and the Perseus Cluster (a massive galaxy cluster). Perseus also hosts the radiant of the annual Perseids meteor ...
NGC 1271 is a compact elliptical or lenticular galaxy [2] located about 250 million light-years away [4] in the constellation Perseus. [5] The galaxy was discovered by astronomer Guillaume Bigourdan on November 14, 1884. [6] NGC 1271 is a member of the Perseus Cluster [7] [6] and has a nuclear dust disk in its center. [3]
