Flight Engineer Don Pettit, one of the Expedition 30 crew members aboard the International Space Station, took this picture of a four-inch polished metal sphere in the U.S. Laboratory Destiny on Feb. 28, 2012. Pettit used an 8-mm lens to achieve what he called a "double fisheye" effect because the sphere itself provides a fisheye reflection. A close look of the sphere reveals a mirrored Pettit.
