NASA's €œBlack Marble€ Project released HD images that shows night-time
views of the earth. This new global view of Earth's city lights is a
composite assembled from data acquired by the Suomi National
Polar-orbiting Partnership (NPP) satellite. The data was acquired over
nine days in April 2012 and 13 days in October 2012. It took 312 orbits
to get a clear shot of every parcel of Earth's land surface and islands.
This new data was then mapped over existing Blue Marble imagery of
Earth to provide a realistic view of the planet.

The image was made possible by the satellite's "day-night band" of the
Visible Infrared Imaging Radiometer Suite, 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.
