Saturn is a Harsh Mistress

Scientists have a new entry in the "where did Saturn's rings come from?" This time, the thought is that, at the start of the solar system, a Titan-sized moon got peeled like an onion as it fell into, and was destroyed by, the planet. I wish they'd spent a little more time on the predictions this theory makes, but it does seem as if the composition of the small inner moons will go a long way toward proving or disproving the idea.
