Saturn’s rings were thought to be under 100M years old (younger than butterflies) because they're so pristine, but this model says they’re a billion years old with a built-in epilator vaporising the space-blemishes to stay pretty, and either way I’m like slay girl www.nature.com/articles/s41...

Pollution resistance of Saturn’s ring particles during micrometeoroid impact - Nature Geoscience

Simulations of micrometeoroid impacts into Saturn’s icy ring particles find limited pollution of the particles by non-icy material, suggesting Saturn’s rings may appear younger than their actual age.
