Their dramatic birth may have taken place a mere hundred million years ago, more recent than the reign of many dinosaurs. “Moons are always changing their orbits. That’s inevitable,” says Matija Cuk, principal investigator at the SETI Institute. “But that fact allows us to use computer simulations to tease out the history of Saturn’s inner moons...
