Hat tip to astronomer Phil Plait over at Bad Astronomy for digging up this gem of an image snapped by astronaut Don Petit aboard the International Space Station. Culled from NASA's Flickr stream, the composite is a series of eighteen 30-second exposures stitched together to capture the motion of the ISS around the Earth, trailing the light from cities and auroras below as well as stars above.

The result is something close to psychedelic. Download the wallpaper-worthy super high-res version over at NASA: 2Explore's Flickr stream, which, by the way, is chock full of interesting astrophotography. Like this. And this.
