An emission nebula which spans 36° dominates the southern skies, in the constellations of Vela and Puppis. It is believed to be the greatly expanded (and still expanding) remains of a supernova that took place about a million years ago. The Gum nebula, named after it’s discoverer, is an emission nebula and is rich in the red ionised hydrogen gases seen in this image. In this narrower 4° view of the Gum nebula, we can see Gum 10 along with cometary globules CG 30-31. Imaged on my Takahashi E160 scope installed in DeepSky Chile remote observatory
