Vela Supernova Remnant
The expanding cloud of gaseous debris thrown out by a supernova in Vela that occurred about 11,000 years ago (although this age is uncertain either way by a factor of two). The Vela Supernova Remnant now spans about 55 light-years from the site of the explosion. At a distance of only 815±98 light-years it is one of the closest supernova remnants to the Sun – so close that sprawls across more than 5° of the sky. It lies within the more extensive and much older Gum Nebula. At its heart is the Vela Pulsar.
