Well, technically it's a brain photographed from space. Astronaut Chris Hadfield, current Commander of the International Space Station, snapped the photograph while orbiting over South America.
"I have no idea what this Brazilian outcrop looks like on the ground," Hadfield tweeted, along with the picture (the latest in a long string of beautiful photographs that Hadfield has taken from aboard the ISS), "but from orbit, it's a brain."
Yes. Yes it is.
