In this image obtained from NASA, on October 13, 2012, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured this nighttime view of the Nile River Valley, its Delta (C), the Sinai (C-R) and the rest of the Middle East. This image is from the VIIRS day-night band, which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe signals such as gas flares, auroras, wildfires, city lights, and reflected moonlight. = RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / NASA" - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS =
