Eastern Veil Nebula - NGC6992

This is the eastern part of a large but relatively faint supernova remnant in the constellation of Cygnus. The rope-like filamentary structures of the nebula are the visible remnants of the shock-wave from the supernova explosion that occurred some 5,000 to 8,000 years ago.
