Southern Milky Way and Gum Nebula

Southern Milky Way from the constellation Orion and Taurus (at top right, with Jupiter) to the Southern Cross and Centaurus (lower left) where the lights of a camping site is visible. The Large Magellanic Cloud appears in the lower middle. In the center of this deep exposure, made with a modified DSLR camera, the extensive Gum nebula is visible. Gum 12 is an emission nebula that is hard to distinguish because it extends across 40° in the southern constellations 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. © Juan Carlos Casado
