New research reveals they formed from a two-stage catastrophe: first, a moon called Proto-Hyperion collided with Titan ~400 million years ago. The resulting chaos destabilized the inner moon system, triggering a second collision that scattered debris inside Saturn's Roche limit, where it could never reassemble into a moon — only spread into rings. Based on Ćuk et al. (Planetary Science Journal, 2026).","shortDescription":"The collisions that created Saturn's rings"}}
