Astronauts always say the view of Earth is the best part of being in space. Here’s a beautiful shot of northwestern Europe at night. The landscape is dotted with clusters of lights from individual urban areas; visible are London, Paris, Brussels, Milan and Amsterdam, which stand out due to their large light “footprints,” while the English Channel is completely dark.
This photograph was taken by one of the Expedition 28 crewmembers on the International Space Station (ISS) and was taken with a short camera lens, providing the wide field of view. To give a sense of scale, the centers of the London and Paris metropolitan areas are approximately 340 kilometers (210 miles) from each other.
