Earth At Night
This NASA image from a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012 shows the city lights of earth at night. The new data was mapped over existing Blue Marble imagery of Earth to provide a realistic view of the planet. 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.
