   Explanation: [5]A ghostly visage on a cosmic scale, these remains of
   shocked, glowing gas haunt planet Earth's sky toward the constellation
   of Cygnus and form [6]the Veil Nebula. The nebula itself is a large
   [7]supernova remnant, an expanding cloud born of the death explosion of
   a massive star. Light from the original supernova explosion likely
   reached Earth over 5,000 years ago. Also known as the Cygnus Loop, the
   [8]Veil Nebula now spans nearly 3 degrees or about 6 times the diameter
   of the full Moon. That translates to over 70 light-years at its
   estimated distance of 1,500 light-years. In fact, the Veil is so large
   its brighter parts are recognized as separate nebulae, including The
   [9]Witch's Broom (NGC 6960) below and right of center. At the top left
   you can find the Spectre of [10]IC 1340. [11]Happy Halloween!
