Vela supernova remnant

(SNR G263.9-03.3)
(nearby supernova remnant)

The Vela supernova remnant (or Pup A) is a supernova remnant about 800 light-years away for a supernova that would have become visible to Earth about 12,000 years ago. It is one of the nearest know SN remnants and is very bright in X-rays. I believe the first noting of it was that of a nebula that forms part of it labeled NGC 2736 or the Pencil Nebula.
