East Veil Nebula
is part of the large Cygnus Loop, a super-nova remnant that covers
about 3 degrees of the sky. The West Veil Nebula, NGC6960 would be
located off the bottom of this image. Both nebulas show red and blue
colors indicating the presence of Ha and OIII gases, respectively. They
are believed to be about 1500 light-years from us, and about 90
light-years across. The remnant was formed when a star exploded into a
super-nova about 8000 years ago. North is to the right.
