This stunning field frames the nebulae Gum 14, 15 and 17 as well as some of the teal coloured filaments of the Vela Supernovae
Remnant. 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 enormous cosmic cloud of glowing hydrogen gas. The
faint emission region is otherwise easy to lose against the background of Milky Way stars. The large and complex nebula
is thought to be a supernova remnant over a million years old, sprawling across the southern constellations Vela and
Puppis. The teal coloured spiderweb like filaments in the top right quarter of the image are the shock fronts of the
more recent Vela Supernova explosion, moving through the interstellar medium.
