Dust and the Western Veil Nebula
Explanation: It's so big it is easy to miss. The
entire Veil Nebula spans six times the diameter of the
full moon, but is so dim you need
binoculars to see it. The nebula was created about
15,000 years ago when a star in the
constellation of the Swan (
Cygnus) exploded. The
spectacular explosion would have
appeared brighter than even
Venus for a week - but there is
no known record of it. Pictured is the western edge of the still-expanding gas cloud. Notable gas filaments include the
Witch's Broom Nebula on the upper left near the bright foreground star
52 Cygni, and
Fleming's Triangular Wisp (formerly known as
Pickering's Triangle) running diagonally up the image middle. What is rarely imaged -- but seen in the featured long exposure across many color bands -- is the reflecting brown
dust that runs vertically up the image left, dust likely created in the cool atmospheres of massive
stars.

Great Picture.
The whole SNR structure reminds me a lot of the internal structure of SNR CAS A.
I conclude that similar processes were probably at play here, even though in my opinion there are no good explanations for the sausage-like characteristics of the structures...

The witch's broom appears to be a functional space broom, it's sweeping dust away from the centre of the Veil.

I must say. This one has a striking resemblance to the dragon in the Teen Titans Go episodes, The Light Begins to Shine.

The Veil Nebula turns me off! I don't like nebulas that look as if they have escaped out of a horror movie!
The horrible grin of the eastern Veil Nebula.
It should be illegal for a nebula to look like that! Go back to your horror movie (or Batman movie?), Eastern Veil Nebula!
Anyway. I like this image that puts the Veil Nebula in its place:

When stars die; they leave such specular
remnants!
