The Veil Nebula - Sharpless 103
Located 1,500 light-years away in the constellation Cygnus is a cloud of heated and ionized gas and dust known as the Veil Nebula. The Veil Nebula is the visible portion of a massive supernova that erupted around 7,000 years ago to form what is now known as the Cygnus Loop. The Veil Nebula has a diameter of 100 light-years which appears to be 6 times the diameter of the full moon in the night sky. Due to the scale of the Veil, astronomers often segment the nebula into western (Caldwell 34), eastern (Caldwell 33) and northern portions. This particular images shows the western portion of the nebula with NGC 6960 (the Witches Broom), NGC 6979 (Pickering’s Triangle), and other significant cataloged objects.
