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]
NGC 1259 is a lenticular galaxy [2] located about 243 million light-years away [3] in the constellation Perseus. [4] The galaxy was discovered by astronomer Guillaume Bigourdan on October 21, 1884 [5] and is a member of the Perseus Cluster. [6] [5] A type Ia supernova designated as SN 2008L was discovered in NGC 1259 on January 14, 2008. [7] [8 ...
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. [1] [2]
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 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.
NGC 1220 is a young compact open cluster in the constellation Perseus. It was discovered by John Herschel in 1831. [5] The cluster is located at l = 143.04°, b = −3.96° in the galactic coordinate system, and is 120 parsecs above the galactic plane. [1] [2] It is approximately 6 m 42 s east and 10′ 12″ south from the nearest visible star ...
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]
NGC 1528 is an open cluster in the constellation Perseus. It was discovered by William Herschel in 1790. It is located in the north-eastern part of the constellation, just under 3 degrees north of μ Persei. Less than 1.5° to the southeast is the open cluster NGC 1545 (m = 6.2).
