Hot Plasma Explosions Inflate Saturn’s Magnetic Field

>From a JPL press release:

A new analysis based on data from NASA’s Cassini spacecraft finds a causal link between mysterious, periodic signals from Saturn’s magnetic field and explosions of hot ionized gas, known as plasma, around the planet.

Scientists have found that enormous clouds of plasma periodically bloom around Saturn and move around the planet like an unbalanced load of laundry on spin cycle. The movement of this hot plasma produces a repeating signature “thump” in measurements of Saturn’s rotating magnetic environment and helps to illustrate why scientists have had such a difficult time measuring the length of a day on Saturn.
