In stunning new images of Earth taken at night, the Suomi NPP satellite shows how the lights from our cities illuminate the black marble globe. The composite image, taken in April and October, was mapped over existing Blue Marble imagery of Earth to provide a realistic view of the planet.

The nighttime view was made possible by the new satellite's "day-night band" of the Visible Infrared Imaging Radiometer Suite. VIIRS 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.

The night side of Earth twinkles with the light, and the first thing to stand out is the cities. "Nothing tells us more about the spread of humans across the Earth than city lights," asserts Chris Elvidge, an NOAA scientist who has studied them for 20 years.

This image of the United States at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October. 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.
