Just for fun: The Earth at night


Recently, NASA and NOAA (the National Oceanic and Atmospheric Administration) produced this short film of the Earth at night. They used the Suomi National Polar-orbiting Partnership (NPP) satellite, which can detect the light coming from a single street light, to scan the night side of the Earth and then superimposed those images over prior Blue Marble ones. 

As Chris Elvidge, NOAA scientist, states:

Nothing tells us more about the spread of humans across the Earth than City lights.
