Saturn's spectacular rings are 'very young'

By Jonathan Amos

We're looking at Saturn at a very special time in the history of the Solar System, according to scientists.

They've confirmed the planet's iconic rings are very young - no more than 100 million years old, when dinosaurs still walked the Earth.

The insight comes from the final measurements acquired by the American Cassini probe.

The satellite sent back its last data just before diving to destruction in the giant world's atmosphere in 2017.

"Previous estimates of the age of Saturn's rings required a lot of modelling and were far more uncertain. But we now have direct measurements that allow us to constrain the age very well," Luciano Iess from Sapienza University of Rome, Italy, told BBC News.

Did the same planetary event lead to both Saturn's rings, and the asteroid crashing into the earth to kill the dinosaurs? Saturn is a long way from here, but it's an interesting coincidence.
