The Vela Supernova is a supernova that occurred about 290  parsecs away in the southern constellation Vela 11,000-12,300 years ago.

On the one hand, the supernova gave rise to the predecessor star, the Vela pulsar , which was observed by astromen at the University of Sydney in 1968 as the first direct evidence of a neutron star as the result of a supernova. On the other hand, the gas thrown into space by the supernova forms a supernova remnant , the Vela Nebula , which has an extension of 35 parsecs or around 100  light years ; the pencil nebula also belongs to the supernova remnant .

X-ray sky survey ( GLAST )

The supernova remnant apparently overlaps with that of Puppis A , which is four times further away. In fact, the Vela supernova is one of the closest to Earth - only the much older supernova, from which the Geminga pulsar arose, is a little closer and possibly also the RX J0852.0-4622 , discovered in 1998 , which like Puppis A. overlaps the appearance of the Vela supernova. The Vela Supernova, Puppis A and Geminga are among the brightest celestial phenomena in the X-ray range .
