Saturn Devoured Its Own Moon: The Moon That Became Saturn's Rings

[00:00:00]100 million years. That's all Saturn's rings have existed in a solar system 4 and 1/2 billion years old. They shouldn't be there, not anymore. For decades, the official story was simple.

[00:00:11][music] The rings formed with Saturn, but they're too bright, too pristine, like fresh ice on a world older than anything alive. Then in 2022, MIT found what was missing. Buried in orbital simulations, [music] a ghost, a moon they named Chrysalis. It had circled Saturn for billions of years, stable, faithful, [music] until Neptune drifted.

[00:00:33]Its gravity nudged Saturn's axis [music] and Chrysalis swung too close. Saturn's tidal forces seized it and over centuries [music] tore it apart from the inside. The debris spread into a disk of ice and shattered rock. Scientists still can't fully explain the timing. [music] What you see through a telescope tonight is what's left of a world Saturn pulled apart with its own gravity. Every photograph of Saturn [music] is an aftermath, and the rings, they're still disappearing.
