Craig Posted November 27, 2012 Share Posted November 27, 2012 http://www.bbc.co.uk/news/science-environment-20510109 stronomers have seen that the temperature of Saturn's moon Tethys has hotter regions uncannily like the 1980s arcade game character Pac-Man. A similar feature was spotted in 2010 on Mimas, another Saturnian moon. A report in Icarus suggests the effect is due to high-energy electrons bombarding the sides of the moons that face their direction of orbital travel. That compacts the surfaces to a hard, icy texture that does not heat or cool as rapidly as the unaffected surface. Link to comment Share on other sites More sharing options...
