Studies suggest ancient moon collision formed Saturn's iconic rings

New computer simulations indicate a giant impact between Saturn's ancient moons likely created the planet's rings.
Data from NASA's Cassini mission helped analyze the potential formation of the rings from such an impact.
The simulations show a collision between moons similar to Dione and Rhea could explain the rings' existence.
The impact would have scattered icy fragments that dispersed around Saturn as rings, while rocky cores formed new moons.
While providing a possible origin, mysteries remain about the rings' formation and Saturn's history.
