NGC-6960, the western arc of the Veil Nebula. This diffuse nebula is a supernova remnant, the remains of a titanic explosion of a star which took place more then 45,000 years ago. It and the eastern arc (NGC-6992, 2.5 degrees WSW) are still expanding from this explosion, forming an immense bubble of gas that is expanding outward at a rate of more than 45 miles per second. The yellowish star in this image is 52 Cygni, which is a double star. NGC-6960 lies approximately 1500 light years from Earth.
