It is tidally disturbed by the smaller lenticular galaxy IC 4970. The largest known spiral galaxy, it has a diameter of over 665,300 light-years (204.0 kiloparsecs).
Named after a condor, a type of vulture that is one of the largest flying birds. The comet effect is caused by tidal stripping by its galaxy cluster, Abell 2667. This galaxy is named after its unusual appearance, looking like a comet. Named after its resemblance to the Pinwheel Galaxy and its location in the Coma Benerices constellation. Named after the constellation it is located in ( Circinus). Its visual appearance is similar to that of a spoked cartwheel. Named for Johann Elert Bode who discovered this galaxy in 1774. It has a spectacular dark band of absorbing dust in front of the galaxy's bright nucleus, giving rise to its nicknames of the "Black Eye" or "Evil Eye" galaxy. It appears to rotate backwards, as the tips of the spiral arms point in the direction of rotation. The two will eventually merge into a single new galaxy called Milkdromeda.Īppearance is similar to an insect's antennae. This is a list of galaxies that are well known by something other than an entry in a catalog or list, or a set of coordinates, or a systematic designation.Īndromeda, which is shortened from "Andromeda Galaxy", gets its name from the area of the sky in which it appears, the constellation of Andromeda.Īndromeda is the closest big galaxy to the Milky Way and is expected to collide with the Milky Way around 4.5 billion years from now. Mostly they are identified by their celestial coordinates together with the name of the observing project ( HUDF, SDSS, 3C, CFHQS, NGC/IC, etc.) There is no universal naming convention for galaxies, as they are mostly catalogued before it is established whether the object is or isn't a galaxy. Galaxy Zoo is a project aiming at a more comprehensive list: launched in July 2007, it has classified over one million galaxy images from The Sloan Digital Sky Survey, The Hubble Space Telescope and the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey. In the 1980s, the Lyons Groups of Galaxies listed 485 galaxy groups with 3,933 member galaxies. The first attempts at systematic catalogues of galaxies were made in the 1960s, with the Catalogue of Galaxies and Clusters of Galaxies listing 29,418 galaxies and galaxy clusters, and with the Morphological Catalogue of Galaxies, a putatively complete list of galaxies with photographic magnitude above 15, listing 30,642. The discovery of the nature of galaxies as distinct from other nebulae ( interstellar clouds) was made in the 1920s. There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe. The following is a list of notable galaxies. You can help by adding missing items with reliable sources. This is a dynamic list and may never be able to satisfy particular standards for completeness.
