Ripples in Saturn’s Rings Reveal the Planet’s “Fuzzy” Core
[ad_1] Previously, researchers thought Saturn’s core was rocky. But data collected by NASA’s Cassini spacecraft, which orbited the ring planet for 13 years before intentionally plunging into its atmosphere in 2017, suggests a larger-than-expected core. Rather than solid rock, Saturn’s core is probably what scientists call “fuzzy,” or a mixture of ice, rock, and metallic … Read more
