Astronomy Picture of the Day - Fleming's Triangular Wisp

Explanation: These chaotic and tangled filaments of shocked, glowing gas are spread across planet Earth's sky toward the constellation of Cygnus as part of the Veil Nebula. The Veil Nebula itself is a large supernova remnant, an expanding cloud born of the death explosion of a massive star. Light from the original supernova explosion likely reached Earth over 5,000 years ago. The glowing filaments are really more like long ripples in a sheet seen almost edge on, remarkably well separated into the glow of ionized hydrogen atoms shown in red and oxygen in blue hues. Also known as the Cygnus Loop and cataloged as NGC 6979, the Veil Nebula now spans about 6 times the diameter of the full Moon. The length of the wisp corresponds to about 30 light years, given its estimated distance of 2,400 light years. Often identified as Pickering's Triangle for a director of Harvard College Observatory, it is perhaps better named for its discoverer, astronomer Williamina Fleming, as Fleming's Triangular Wisp.

It looks like an anaglyph. However, the Three-D glasses didn’t show anything

It reminds me of the time I swallowed and ate so-called “abusive” spicy chicken wings as they flowed down through my throat and esophagus. I think they were more red chili peppers than chicken...

And every dot of light is either a star or another galaxy. Millions of planets, the universe has no end, think about that. Yet we are a mere speck in this vast universe of spectacular divinity. Where is the end and where is the beginning?

Amazing fan-made film for Rush's "Cygnus X-1" chock full of cosmic imagery for astronomy and sci-fi fans.

Not Rush Limbaugh, though he may be out there somewhere.
