Viewing Our World From Space, at Night

Today, April 22nd, is Earth Day. This is a unique view of what our world looked like last year, courtesy of the U.S. space agency, NASA, and the National Oceanic and Atmospheric Administration. It is our planet on cloudless nights, with electric light, wildfires, and natural and political borders visible, as seen from the Suomi National Polar-orbiting Partnership mission satellite.
