Ripples in Saturn's rings reveal planet's 'fuzzy' core

Washington: A rippling detected within the rings around Saturn has helped scientists determine that the giant planet may be "fuzzy" at its core.

Previously, researchers believed Saturn's core was rocky. But data gathered by NASA's Cassini spacecraft, which orbited the ringed planet for 13 years before intentionally plunging into its atmosphere in 2017, suggests a larger core than previously estimated. Rather than solid rock, Saturn's core is likely what scientists refer to as "fuzzy," or a slushy mix of ice, rock and metallic fluids.
