The new findings don’t tell us exactly how the rings came to be, but the team thinks it’s likely some sort of dramatic, catastrophic collision within the Saturnian system played a role. “Something blew apart and made these gazillion ring particles that we see today,” says Militzer. Given that the rings are so young, “it did not happen when the solar system formed.” Coincidentally, the timeframe of formation of the rings—10 to 100 million-years-old—is the same timeframe of when the dinosaurs were wiped out (65 million years ago), also by an impact. It’s far from clear whether those events are related in any sort of way, but these new findings suggest that perhaps the solar system was in the midst of some sort of unusual upheaval of objects and collisions at the time. Iess adds that some colleagues think the findings help support the idea that even the inner moons of Saturn are young bodies.
