NGC 2736 - Pencil Nebula in the Constellation Vela (the Sails)

The Pencil Nebula is a very small part of a giant supernova remnant in the constellation Vela. The currently 650,000 kilometers per hour fast shock front of the star, which exploded 11,000 years ago, hits the denser interstellar gas and excites it to glow.
