- This new global view and animation of Earth’s city lights is a composite assembled from data acquired by the Suomi 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.
