December 6, 2012

Almost 40 years to the day after the Apollo 17 crew snapped the famed "blue marble" image of Earth floating in space on December 7, 1972, NASA unveiled an unprecedented new look at our planet at night.

The cloud-free pictures, taken with a high-resolution visible and infrared imager aboard a NASA and National Oceanic and Atmospheric Administration satellite, capture the night lights of Earth in unprecedented detail. The so-called day-night band of the Visible Infrared Imaging Radiometer Suite, or VIIRS.
