Stars leave streaks of light in concentric circles in this March 16, 2012, view from the International Space Station. To create this composite long exposure, NASA astronaut Don Pettit combined multiple 30-second exposures from a mounted camera on the space station into one image.
The orbiting laboratory travels 5 miles per second, traveling around our planet every 90 minutes.
