Veil Nebula Complex

The full Veil Nebula complex spans about 3 degrees of sky — roughly six full Moon widths — and represents the complete shell of a supernova remnant in Cygnus around 2,100 light-years away. This mosaic captures the Western Veil (NGC 6960), Eastern Veil (NGC 6992), and Pickering’s Triangle (IC 1340), a fainter central section discovered photographically by Williamina Fleming in 1904. The entire structure is still expanding at over 150 km/s.
