Pacman has been spotted on the surface of one of the solar system’s most striking moons. Saturn’s moon Mimas has previously been compared with the Death Star because of a large scar on its surface called the Herschel crater. Now NASA’s Cassini probe created the best temperature map yet of the moon, using data collected during a fly-by in February. It reveals a pattern that resembles Pacman eating a dot centred on the distinctive crater. It’s unclear what has caused the pattern. “We suspect the temperatures are revealing differences in texture on the surface,” says John Spencer at Southwest Research Institute in Boulder, Colorado.
