The Perseus molecular cloud (Per MCld) is a nearby (~1000 ly) giant molecular cloud in the constellation of Perseus and contains over 10,000 solar masses of gas and dust covering an area of 6 by 2 degrees. Unlike the Orion molecular cloud it is almost invisible apart from two clusters, IC 348 and NGC 1333, where low-mass stars are formed. It is ...
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.
Perseus A, [1] PGC 12429, [1] UGC 2669, [1] QSO B0316+413, Caldwell 24, 3C 84 [1] 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 1277 is a lenticular galaxy in the constellation of Perseus.It is a member of the Perseus Cluster of galaxies and is located approximately 73 Mpc (megaparsecs) [2] or 220 million light-years from the Milky Way.
The Double Cluster in Perseus (lower left of center, wide angle view) Greek astronomer Hipparchus cataloged the object (a patch of light in Perseus) as early as 130 BCE. To Bedouin Arabs the cluster marked the tail of the smaller of two fish they visualized in this area, and it was shown on illustrations in Abd al-Rahman al-Sufi's Book of Fixed Stars. [4]
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 star has about 1.5 [6] times the mass of the Sun and 9 [4] times the Sun's radius. It radiates 40 [6] times the solar luminosity from its outer atmosphere at an effective temperature of 4,857 K. [6] Kappa Persei B is at an angular separation of 44.10 arc seconds along a position angle of 319°, as of 2009. [9]
Messier 34 (also known as M34, NGC 1039, or the Spiral Cluster) is a large and relatively near open cluster in Perseus.It was probably discovered by Giovanni Batista Hodierna before 1654 [4] and included by Charles Messier in his catalog of comet-like objects in 1764.
