NASA Probe Finds Second Pac-Man Moon on Saturn

Could be a normal heat distribution on some moons


Cassini already spotted the Pac-Man thermal shape on the Mimas moon in 2010, and this second shape—found in Tethys, one of Saturn's 62 icy moons—shows that warmer areas in this pattern could be pretty normal for moons.

"Finding a second Pac-Man in the Saturn system tells us that the processes creating these Pac-Men are more widespread than previously thought," said Carly Howett, lead author of a paper on Tethys.
