Belgium. A nighttime view of Liege, Belgium is featured in this image photographed by an Expedition 34 crew member on the International Space Station. To paraphrase the old expression, "all roads lead to Liege" -- or at least one could get that impression from this nighttime photograph. The brightly lit core of the Liege urban area appears to lie at the center of a network of roadways—traceable by continuous orange lighting—extending outwards into the rural, and relatively dark, Belgium countryside. For a sense of scale the distance from left to right is approximately 70 kilometers. The region at upper left to the southeast of Verviers includes agricultural fields and forest; hence it appears almost uniformly dark at night. [NASA]
