# List of supernovae

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.

## List of supernovae

In most entries, the year when the supernova was seen is part of the designation (1st column).
| Supernova designation (year) | Constellation | Observations | Apparent magnitude | Distance (light years) | Type | Galaxy | Comments |
| SN 185 | Centaurus | 7 December 185 | −4 (?) | 9,100 | Ia (?) | Milky Way | Surviving description sketchy; modern estimates of maximum apparent magnitude vary from +4 to −8.
