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.
