This is a list of observed supernova remnants (SNRs) in the Milky Way, as well as galaxies nearby enough to resolve individual nebulae, such as the Large and Small Magellanic Clouds and the Andromeda Galaxy.
Supernova remnants typically only survive for a few tens of thousands of years, making all known SNRs fairly young compared to many other astronomical objects.
