     This photo of Earth is actually comprised of several photos taken by Suomi NPP (an Earth observing satellite launched by NASA) and a VIIRS instrument ( Visible/Infrared Imager Radiometer Suite- the primary imaging tool onboard Suomi NPP).  In order to put together such a photograph, the satellite had to make four orbits.  The data collection was done earlier in January.
