That old question about the age of Saturnís rings

A team of researchers has reignited the debate about the age of Saturn’s rings with a study that dates the rings as most likely to have formed early in the Solar System. In a paper published today in Nature Astronomy and presented at the EPSC-DPS Joint Meeting 2019 in Geneva, the authors suggest that processes that preferentially eject dusty and organic material out of Saturn’s rings could make the rings look much younger than they actually are. Cassini’s dive through the rings during the mission’s Grand Finale in 2017 provided data that was interpreted as evidence that Saturn’s rings formed just a few tens of millions of years ago, around the time that dinosaurs walked the Earth. Gravity measurements taken during the dive gave a more accurate estimate of the mass of the rings, which are made up of more than 95% water ice and less than 5% rocks, organic materials and metals. The mass estimate was then used to work out how long the pristine ice of the rings would need to be expo
