New Theory on Titan's Formation and Saturn's Rings

New research, led by Matija Ćuk of the SETI Institute, proposes a novel origin story for Saturn's largest moon, Titan, and its rings. Combining data from United States===NASA's Cassini–Huygens spacecraft and computer simulations, the study suggests that Titan formed about half a billion years ago from a collision and merger of two earlier moons, Proto-Titan and Proto-Hyperion. This event is hypothesized to explain Titan's drifting orbit, Saturn's current tilt, and the subsequent formation of Saturn's rings through disturbances to inner moons. The theory also accounts for the relatively young age of Titan's surface and Hyperion's chaotic orbit. United States===NASA's upcoming Dragonfly mission to Titan is expected to provide crucial evidence to test this hypothesis.
