Story summary

SETI Institute researchers propose Titan formed about 400 million years ago from the collision of two massive moons, an event that also helped form Saturn's rings.
The study suggests Hyperion formed from debris of this collision.
The findings challenge beliefs about the rings’ age and link Titan’s young surface to fewer impacts.
NASA's Dragonfly mission is scheduled to reach Titan in 2034 to test the hypothesis.
