Happy Earth Day! - UNIVERSE

Earth as seen by the NASA/NOAA DSCOVR satellite on July 6, 2015.

Orbiting at the L1 point between the Earth and the Sun, DSCOVR takes images of the illuminated hemisphere of the Earth as it rotates underneath.  This is in contrast to geostationary satellites, which orbit at the same speed that the Earth rotates, seeing day and night pass over the same location.
