This view of Earth at night is a cloud-free view from space as acquired by the United States's NASA program. This new image is a composite of data acquired over nine days in April and thirteen days in October 2012. It took 312 satellite orbits and 2.5 terabytes of data to get a clear shot of every parcel of land surface.
