I Zwicky 18. Sounds like a robot from Star Wars, doesn't it? Close. It's a galaxy that found itself in list25's Most Bizarre Galaxies In The Universe because: a large amount of ionized helium is present, making scientists wonder what is emitting radiation strong enough to kick electrons off their helium atoms.
I think it's pretty.
And that's a wrap, folks! Twenty-six days of weird science! Huzzah! Over and out. Stick a fork in me. You can go get "Zwicky" with it, but I need a nap.
