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 .
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 1245 is an open cluster in the constellation Perseus. It was discovered by William Herschel in 11 December 1786. [2] It is located 3° southwest of alpha Persei and can be spotted with 10x50 binoculars. [3] The cluster is nearly 1 billion years old. [4] NGC 1245 has about 200 members the brightest of which are of 12th magnitude. [5]
MACS J0152.5-2852 is a massive galaxy cluster. Almost every pixel seen in the image is a galaxy, each containing billions of stars. [1]Galaxy groups and clusters are the largest known gravitationally bound objects to have arisen thus far in the process of cosmic structure formation. [2]

The supergalactic coordinate system is a reference frame for the supercluster of galaxies that contains the Milky Way galaxy, referenced to a local relatively flat collection of galaxy clusters used to define the supergalactic plane. The supergalactic plane is more or less perpendicular to the plane of the Milky Way; the angle is 84.5°.
Photons emitted from the center of a galaxy cluster should lose more energy than photons coming from the edge of the cluster because gravity is stronger in the center. Light emitted from the center of a cluster has a longer wavelength than light coming from the edge. This effect is known as gravitational redshift. Using the data collected from ...
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.
