NASA has released an extraordinary tape of the sound picked up by the Cassini spacecraft as it plunged into Saturn on its final mission in 2017. The craft captured plasma waves from Saturn to its rings and into one of its moons, Enceladus. It is mesmerizing. It has been describing as Saturn singing and it is strangely beautiful.
The sound is the result of plasma waves moving through magnetic field lines on the way to Enceladus.
NASA took the waves and converted them into an audio file the way that radio converts electromagnetic waves into music. It then reduced the 16 minutes to 28.5 seconds. The result is a cosmic hit.
