After completing all of its objectives and its propellant exhausted, the Cassini spacecraft was sent plunging to its demise into Saturn's atmosphere in September of 2017 after performing a "Grand Finale" by zooming through the gap between the planet and its rings.

Data compiled by the intrepid probe allowed for scientists to peer into the depths of Saturn’s interior makeup where its massive magnetic field churns. In new research paper published in the online journal, AGU Advances, two planetary scientists at Johns Hopkins University employed computer simulations to test the theory of whether the implementation of a helium rain layer at the top of Saturn’s dynamo zone might influence and reproduce a magnetic field similar to the planet’s surface magnetic field.
