NGC-6992 is the eastern arc of the Veil Nebula, a supernova remnant which lies about 2.5 degrees to the ENE of NGC-6960, the western arc. These two arcs are part of a huge bubble of gas that is the result of a titanic explosion of a star which took place over 45,000 years ago. This bubble is still expanding at a rate of 45 miles per second! Both arcs of the Veil Nebula lie at a distance of 1500 light years from Earth.
