New research from the up-close Grand Finale orbits of NASA's Cassini mission shows a surprisingly powerful interaction of plasma waves moving from Saturn to its moon Enceladus.
Sounds of Saturn:
Hear Radio Emissions of a Planet and Its Moon
Cassini's final orbits revealed a powerful interaction between Saturn and the moon Enceladus. Scientists observed plasma waves moving in a circuit from planet to moon. The waves were converted into audio we can hear.

Time was compressed from 16 minutes to 28.5 seconds, and wave frequency was
decreased by a factor of 5. Cassini captured the data on September 2, 2017, two weeks before the spacecraft plunged into Saturn's atmosphere.
