Revised age estimate for Saturn's rings suggests they are much younger than previously believed.
TL;DR Summary
A new study led by physicist Sascha Kempf at CU Boulder has found that Saturn's rings are much younger than previously thought, with an age of no more than 400 million years old. The researchers arrived at this conclusion by studying the buildup of dust on the rings, which suggests that the rings have only been gathering dust for a few hundred million years. The study also raises questions about how the rings formed in the first place.
