Earth at night NASA photos

This image provided by NASA from a composite assembled from data acquired by the Suomi NPP satellite shows Great Britain, Ireland, and part of northwestern Europe, including France, Belgium and the Netherlands, as they appeared on the night of March 27, 2012. The image was made possible by the new satellite's "day-night band" of the Visible Infrared Imaging Radiometer Suite (VIIRS), which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as city lights, gas flares, auroras, wildfires and reflected moonlight.
