The Network Nebula

NGC6992 was originally discovered by William Herschel in 1784 in the constellation of Cygnus.  The Network Nebula is only the eastern section of a much larger object called the Veil Nebula.  The Veil Nebula, which appears as a giant loop of Hydrogen Alpha ionized gas, is a large-scale remnant of a supernova that occurred approximately 30,000 to 40,000 years ago and is still expanding at a speed of 116 kilometers per second.  This is one of the oldest known supernova remnants and lies about 2,500 light years from Earth.
