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.
