The Vela Supernova Remnant (Gum 16), Vela

A young supernova remnant, the remains of a star that exploded about 12,000 years ago, is visible as the turquoise and red filaments to right of centre (contains the Vela pulsar, a neutron star, the degenerate core of the dead star), superimposed on the much larger Gum Nebula. It lies roughly 800ly away.  Below are two other objects from Gum's catalogue, Gum 17  and Gum 15. The stars, g Velorum is upper left of centre, z Velorum is lower left and l Velorum is right of centre.
