On Wednesday 5 December 2012, NASA released a composite image of the Earth at Night – the “Black Marble” – showing the extent of human activity in unprecedented detail. The accompanying video (link below) takes the viewer on a remarkable journey through the night – from gas flares in Saudi Arabia to fishing fleets worldwide and bush fires across Australia.
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.
