It’s been a while since I posted one of these…it’s an animation made up of 16 raw images from the Cassini spacecraft, taken on March 12, showing Saturn’s moons Dione and Titan passing each other. The small, cratered and frozen Dione couldn’t be more different than her much larger, haze-enshrouded sister Titan, but we’re reminded that they both share a place in orbit around Saturn…along with 51 other officially named moons, with more on the way.
