Menacing flying forms and garish colors are a mark of the Halloween season. They also stand out in this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the exp
anding
debris cloud from the death explosion of a massive star. While the Veil
is roughly circular in shape covering nearly 3 degrees on the sky in
the constellation Cygnus, this portion of the eastern Veil spans only
1/2 degree, about the apparent size of the Moon. That translates to 12
light-years at the Veil's estimated distance of 1,400 light-years from
planet Earth. In this composite of image data recorded through narrow
band filters, emission from hydrogen atoms in the remnant is shown in
red with strong emission from oxygen atoms in greenish hues. In the
western part of the Veil lies another seasonal apparition, the Witch's
Broom.
