Super galaxy
Super galaxy, also written as super-galaxy or supergalaxy, is an astronomical term used either to describe giant galaxies, formed from multiple galaxies,[1] or to describe superclusters of galaxies.[2] The newest Super galaxy was discovered in 2022, and the size of it dwarfs anything ever discovered before. It is 16.3 million light-years wide and was named the Alcyoneus (galaxy).
Description
The term has a long history, first being used in 1912. Super galaxies were theorized to exist before they were first observed. Misunderstandings due to early observations led to the belief that galaxy clusters were actually one giant galaxy.
Notable examples are Abell 2029, Perseus A, Centaurus A (NGC 5128), NGC 6166, and the Perseus-Pisces super galaxy cluster. The creation of a super galaxy, by the destruction of smaller galaxies, is a recent understanding in astrophysics.
The Antennae galaxies, currently in collision, are predicted to eventually form a supergalaxy.[3][4]
A super galaxy is not the same as a supercluster. (de Vaucouleurs first called the nearest cluster of galaxies the "Local Supergalaxy," but in 1958 he renamed it the Local Supercluster.[5])
