This is a small piece of
the entire Veil Nebula in
Cygnus. The Veil is
supposedly another
supernova remnant,
though the post-nova
star that is exciting the
gas to glow has not
been clearly identified.

Please contrast this
image with the wider
field version shown
here.

Please contrast with
another famous
supernova remnant, the
Crab Nebula.
