NGC 6992 - The Network Nebula (a.k.a. the Eastern Veil Nebula)

The Veil Nebula is the remnant of a supernova explosion that occurred thousands of years ago. At its peak, the "new star" could have been as bright as the crescent Moon but it soon faded to become invisible to human vision. Discovered by William Herschel in 1784, the Veil Nebula is the expanding cloud of the gases of the exploded star, plowing through space and exciting interstellar atoms to glow with characteristic light - red for atomic hydrogen and blue-green for oxygen.

The distance to this object is not accurately known but has been calculated to be about 2,000 light years away.

The Veil nebula is an extended object and consists of different parts, each catalogued with a different name. This image was shot with a small refractor telescope and a DSLR camera and depicts the eastern part of the Veil, which is often referred to as the Network nebula. For an image of the western part of the Veil (NGC 6960), see:
