The Veil Nebula

Roughly 8,000 years ago a supernova was seen in what we now know as the constellation Cygnus, the Swan. Today the Veil Nebula, also known as the Cygnus Loop, is the only known remnant of this star. The entire loop is about three degrees wide and  comprises  two primary sections with a number of fainter ones. A large amateur telescope reveals all the twisted, filamentary detail seen here. The nebula continues to expand and will eventually disperse into invisibility.
