"Cassini" recorded the electromagnetic songs of Saturn and Enceladus

An analysis of the data collected during the last orbits of the Cassini apparatus presented a new discovery. A team of researchers from the University of Iowa (University of Iowa) discovered an unexpectedly strong interaction of plasma waves between Saturn, its rings and satellite Enceladus.

The researchers turned the recording of Cassini data, made with an RPWS (Radio Plasma Wave Science) plasma spectrometer, into an accessible audio file. This is similar to how radio transforms electromagnetic waves into music. The recording was made on September 2, 2017 - two weeks before the completion of the mission. Her time was compressed from 16 minutes to 28.5 seconds.
The interaction of Saturn and Enceladus is special. In the depths of Enceladus contains the subsurface ocean, the water from which is actively released into the surrounding space through a network of faults at the south pole of the satellite.These emissions are then ionized. The interaction of the plasma medium and the Saturn magnetosphere leads to the appearance of waves moving along the magnetic field lines connecting the gas giant and its oceanic world.
