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.

OK, the neither the moons nor the Pac-Man features are "on" Saturn; they orbit around Saturn as all moons do around their primaries.

The headline is ambiguous, and my first interpretation is that a new moon had been found; this is a newly discovered feature of a moon which we've known about for over 200 years.
