Excerpt:

Earth-watching scientists over at NASA today rolled out what they call the “Black Marble,” a series of new images and video featuring Earth as seen from space at night. The images come from a new sensor on board the Suomi National Polar-orbiting Partnership satellite (NPP) launched last year by NASA and NOAA. NASA’s composite animation was stitched together with images gathered over 312 satellite orbits.   It took that many passes to get cloud-free images of every continent and island on the planet. NASA claims the new sensor — called VIIRS, or the Visible Infrared Imaging Radiometer Suite — is so sensitive it can pick up the light of a single ship in the middle of the ocean.
