A small section of the expanding remains of the Veil Nebula, a massive star that exploded about 8,000 years ago, is seen in an image from NASA's Hubble Space Telescope released September 24, 2015. The entire nebula is 110 light-years across, covering six full moons on the sky as seen from Earth, and resides about 2,100 light-years away in the constellation Cygnus, the Swan, according to NASA.
