On May 28th, 2011, the day before Endeavour undocked from the International Space Station, an astronaut snapped this amazing shot out a window of the ISS. Endeavour is partially seen, payload bay doors open wide, as well as ISS equipment, and some stars in the night sky. But the scene-stealer is the Earth itself, blurred slightly in this time exposure, cities streaking by as this man-made structure orbits 400 kilometers (250 miles) above the Earth, traveling at 28,000 kph (17,000 mph).
