This image of the Veil Nebula was taken with the Mosaic camera on the WIYN 0.9-meter telescope at Kitt Peak National Observatory. The Veil Nebula (NGC 6960) is part of a supernova remnant known as the Cygnus Loop. It is the shattered remains of one, and possibly two, supernovae that exploded more than 15,000 years ago at a distance of 2,500 light-years from Earth in the direction of the constellation of Cygnus, the Swan. At the time of the explosion, it would have been seen as a very bright star, rivaling the crescent Moon. The bright star near the center of the image, known as 52 Cygnus, is not associated with the supernova. The color image was generated by combining data from narrowband filters; data from H-alpha was assigned a red color, [OIII] is blue and [SII] is green. North is to the left and East is down.
