Pac-Man Moons

I've heard of life imitating art, but this is ridiculous. NASA has released these Thermal Images of Saturn's Moons Mimas (2010) and Tethys (2012) which clearly show two stages in the animation of the 1980s arcade character Pac-Man. Both images were captured by the Cassini-Huygens mission, launched in 1997 to study the Saturn system. Astronomers reckon that fast-moving electrons create the temperature differences that make these Pac-Man shapes (CLICK).
