Western Veil Nebula, "Witch's Broom"
is part of the large Cygnus Loop, a super-nova remnant that covers
about 3 degrees of the sky. The Eastern Veil Nebula, NGC6992 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 left.
