Explanation:
Frightening
forms and scary faces are a mark of the Halloween season.
They also haunt
this
cosmic close-up of the eastern Veil Nebula.
The Veil Nebula itself is a
large supernova remnant, the expanding
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
reassuring estimated distance of 1,400 light-years from planet Earth.
In the 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 blue-green hues.
In the western part of the Veil lies another seasonal apparition,
the Witch's Broom.
