The Network Nebula
is the eastern portion of the much larger complex known as the Veil Nebula
complex. It is caused by an expanding shockwave from a supernova that
exploded in the area some 10,000 years ago. The Nebula is not part of the
remains of the original supernova star, but the result of the expanding
shockwave interacting with pre-existing gases in the area heating them to
millions of degrees and causing them to glow with their characteristic
colors.
NGC6992 lies at a distance of 1500 light years.
