The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. [ 4 ] It constitutes the visible portions of the Cygnus Loop , [ 5 ] a supernova remnant , many portions of which have acquired their own individual names and catalogue identifiers.
The Cygnus Loop (radio source W78, or Sharpless 103) is a large supernova remnant (SNR) in the constellation Cygnus, an emission nebula measuring nearly 3° across. [1] Some arcs of the loop, known collectively as the Veil Nebula or Cirrus Nebula, emit in the visible electromagnetic range. [1] Radio, infrared, and X-ray images reveal the ...

Part of another diffuse nebula IC 4703. Rosette Nebula: 130 ly (40 pc) [43] H II region: Only 36 stars were known to be in this nebula but the Chandra telescope increased the number of known stars to 160. Lagoon Nebula: 110 ly (34 pc) [44] H II region: Veil Nebula: 100–130 ly (31–40 pc) [45] Supernova remnant: Located in the Cygnus Loop ...
NGC 6992 (Eastern Veil Nebula – center) and NGC 6960 (Western Veil Nebula – upper right) photographed from a dark site. To the south of Epsilon Cygni is the Veil Nebula (NGC 6960, 6979, 6992, and 6995), a 5,000-year-old supernova remnant covering approximately 3 degrees of the sky - [66] it is over 50 light-years long.
