SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
Novae are initially designated via a "Nova [genitive form of constellation name] [year of discovery]" format, e.g. "Nova Cygni 1974" and "Nova Scorpii 2010". An official permanent name is usually soon assigned by the General Catalog of Variable Stars using the GCVS format for the naming of variable stars. When more than one nova is discovered ...
Type Ia supernova; Type Ib and Ic supernovae; Type II supernova; Superluminous supernova; Pair-instability supernova; Hypernova; Supernova impostor, stellar explosions that appear similar to supernova, but do not destroy their progenitor stars Failed supernova; Luminous red nova, an explosion thought to be caused by stellar collision
Map showing various supernova candidates, most of which are within one kiloparsec from the Solar System. [1] This is a list of supernova candidates, or stars that are believed to soon become supernovae. Type II supernova progenitors include stars with at least 8~10 solar masses that are in the final stages
The word supernova has the plural form supernovae (/-v iː /) or supernovas and is often abbreviated as SN or SNe. It is derived from the Latin word nova, meaning ' new ', which refers to what appears to be a temporary new bright star. Adding the prefix "super-" distinguishes supernovae from ordinary novae, which are far less luminous.
Note that this list is mainly about the development of knowledge, but also about some supernovae taking place. For a separate list of the latter, see the article List of supernovae. All dates refer to when the supernova was observed on Earth or would have been observed on Earth had powerful enough telescopes existed at the time.
