Lights across the earth are pictured in this NASA handout satellite image obtained by Reuters Dec 5, 2012. This new image of the Earth at night is a composite assembled from data acquired by the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite over nine days in April 2012 and thirteen days in Oct 2012. It took 312 orbits and 2.5 terabytes of data to get a clear shot of every parcel of Earth's land surface and islands. [Photo/Agencies]
