Saturn's 'Death Star' Moon May Hide Subsurface Ocean

astroengine writes With its heavily cratered, geologically dead surface, Saturn's moon Mimas was considered to be scientifically boring. But appearances can be deceiving. Using data from NASA's Cassini spacecraft, new research shows something strange inside Mimas that is causing the moon to sway as it orbits around the ringed gas giant. Computer models point to two possibilities. First is that Mimas, which is about 250 miles in diameter, has an oblong or football-shaped core, a clue that the moon may have formed inside Saturn's ice rings. The second option is that Mimas has a global ocean located 16 miles to 19 miles beneath its icy crust.

      Have you even looked at much science from the 19th century? If you are only considering the people and work that are famous for standing the test of time, then it shouldn't be a surprise that their work is still viewed as good. There were all sorts of crazy ideas for generating energy, and some horrendous measurements of the speed of light that were off by an order of magnitude. There always have been a share of bad scientists, the difference now is that mistakes for some of those things are in the parts per million or billion, something far beyond the detail of previous centuries.
