The brightly lit metropolitan areas of Torino (Italy), Lyon, and Marseille (both in France) stand out amidst numerous smaller urban areas in this dramatic photo from the international space station. The image captures the nighttime appearance of the France-Italy border. The southwestern end of the Alps Mountains separates the two countries. The island of Corsica is visible in the Ligurian Sea to the south (image top). The full moon reflects brightly on the water surface and also illuminates the tops of low patchy clouds over the border (center). Photo courtesy of NASA.
