Commander Chris Hadfield has been tweeting photos from the International Space Station for months now, and many of his images are utterly gorgeous.

Post your favorite pictures of Earth from space. For inspiration, here is Hadfield's Twitter feed, and here is a gallery on NASA of satellite photos taken from Earth orbit.
