Amy's crack is real and we've got proof!
Turns out it's the image of the day and referred to as a "Ghost Snake" in the article (apparently sketched by the same Disney cartoonist that worked on the Jungle Book, in this animation) at the Daily Galaxy website. The article states:
"A cosmic snake appears to slither across the plane of our Milky Way galaxy in this image from NASA's Spitzer Space Telescope. The snake-like object located about 11,000 light-years away in the constellation Sagittarius is actually the core of a thick, sooty cloud large enough to swallow dozens of solar systems and may be harboring beastly stars in the process of forming."
There's much more of it and quite interesting. But the really fun bit are the comments. I bet those astronomers weren't expecting those. Doctor Who fans are awesome. That's all. Click here to go directly to the article.
