Explanation: The Gum Nebula is so large and close it is actually hard to see. In fact, we are only about 450 light-years from the front edge and 1,500 light-years from the back edge of this cosmic cloud of glowing hydrogen gas. The complex nebula is thought to be a supernova remnant over a million years old, sprawling across the southern constellations Vela and Puppis.
