The name of this galaxy is based on a Redshift (z) measurement of nearly 7 (actually, z = 6.604). [ 5 ] Galaxy Cosmos Redshift 7 is reported to be the brightest of distant galaxies (z > 6) and to contain some of the earliest first stars ( first generation ; Population III ) that produced the chemical elements needed for the later formation of ...
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek galaxias, literally 'milky', a reference to the Milky Way galaxy that contains the Solar System.
A black hole (artist concept); Vela Pulsar, a rotating neutron star; M80, a globular cluster, and the Pleiades, an open star cluster; The Whirlpool galaxy and Abell 2744, a galaxy cluster; Superclusters, galactic filaments and voids
The name was originally Arabic: الذيل aḏ-ḏayl (the train, lit. 'the tail'). /əˈdɪl/ Taurus: ε Tauri Aa1: Ain: The name is originally from Arabic: عين ʿayn ('eye') and was reviewed and adopted by the Working Group on Star Names.

Listed below are galaxies with diameters greater than 700,000 light-years. This list uses the mean cosmological parameters of the Lambda-CDM model based on results from the 2015 Planck collaboration, where H 0 = 67.74 km/s/Mpc, Ω Λ = 0.6911, and Ω m = 0.3089. [3]
A spiral galaxy is a type of galaxy characterized by a central bulge of old Population II stars surrounded by a rotating disc of younger Population I stars. A spiral galaxy maintains its spiral arms due to density wave theory.

Voids are particularly galaxy-poor regions of space between filaments, making up the large-scale structure of the universe. Some voids are known as supervoids . In the tables, z is the cosmological redshift , c the speed of light , and h the dimensionless Hubble parameter , which has a value of approximately 0.7 (the Hubble constant H 0 = h × ...
