Africa at night. Black marble satellite image of Africa at night. More densely populated areas are brighter. The Nile is illuminated by the many boats along its length. The nocturnal glow produced by the Earth's atmosphere is shown as well as man-made light. Data acquired by the day-night band of the Visible Infrared Imaging Radiometer Suite (VIIRS) on board the NASA-NOAA Suomi National Polar-orbiting Partnership (NPP) satellite, over nine days in April 2012 and 13 days in October 2012.
