Saturn's icy rings likely formed from lost moon Chrysalis

Phys · · 656 words · By Laurence Tognetti

The article discusses a scientific study presented at the 57th Lunar and Planetary Science Conference regarding the origin of Saturn's rings. Researchers used computer models to suggest that the rings formed approximately 100 million years ago from the gravitational dismantling of an ancient moon named Chrysalis.
