Saturn’s rings are much younger than we thought

A team of researchers arrived at the new birth date estimate for Saturn’s rings by studying the build-up of dust around the gas giant planet. Tiny grains of rock stream through the solar system on a near-constant basis, resulting in thin layers of the material building up on planets, moons and asteroids and in icy ring systems like that of Saturn. To try and arrive at a new age estimate for Saturn’s ring system, researchers studied how rapidly this dust layer gathers, similar to determining how long a surface in your house has been left untouched by running a finger over it.
