List of supernovae
This is a list of supernovae that are of historical significance. These include supernovae that were observed prior to the availability of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
(Crab Nebula)
An alternative, complete and updated list can be found in the Open Supernova Catalog. Recent supernovae can be found at Latest Supernovae. Supernovae in 2023 include SN 2023ixf in Messier 101 (May 2023),[1] SN 2023idj in NGC 4568 (May 2023) and SN 2023gfo in NGC 4995 (April 2023).
List of supernovae edit
In most entries, the year when the supernova was seen is part of the designation (1st column).
