Explanation: Braided and serpentine filaments of glowing gas suggest this nebula's popular name, The Medusa Nebula. Also known as Abell 21, this Medusa is an old planetary nebula some 1,500 light-years away in the constellation Gemini. Like its mythological namesake, the nebula is associated with a dramatic transformation. The planetary nebula phase represents a final stage in the evolution of low mass stars like the sun as they transform themselves from red giants to hot white dwarf stars and in the process shrug off their outer layers. Ultraviolet radiation from the hot star powers the nebular glow. The Medusa's transforming star is the faint one near the center of the overall bright crescent shape. In this deep telescopic view, fainter filaments clearly extend above and right of the bright crescent region. The Medusa Nebula is estimated to be over 4 light-years across.

This post is a blatant attempt at a thread hijack.
The mods should step in, but they are all at Happy hour in Fresno.

That’s just too weird for me right now.
I’m gonna smoke some weed and look again later.
I’ll let you know how that goes...

5 minutes of that can possibly drive someone insane.
I wonder how long the original animation is? Then again, it’s probably computer generated and would go on forever.
