The Ghostly Veil Nebula Image Credit & [3]Copyright: [4]Anis Abdul 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!
