Space music: NASA listens in on Enceladus

Saturn and its moon Enceladus are communicating through plasma waves that are constantly being exchanged, and scientists have recorded these conversations, Popular Mechanics noted. The field is like a direct circuit between the planet and its Moon where energy flows back and forth, making unusual sounds along the way.

NASA's Cassini spacecraft's Grand Finale orbits found a powerful interaction of plasma waves moving from Saturn to its rings and its moon Enceladus. Similar interactions take place between Saturn and its rings, as they are also very dynamic.

Moving along the magnetic field lines the plasma particles - electrons and ions - are accelerated and radiate electromagnetic waves, which scientists call plasma waves. The recording time was compressed from 16 minutes to 28.5 seconds. Our own Moon does not interact in the same way with Earth.

The latest audio was recoded September 2, 2017, just two weeks before Cassini began its final plunge into Saturn's atmosphere.

'Now we find that Saturn responds by launching signals in the form of plasma waves, through the circuit of magnetic field lines connecting it to Enceladus hundreds of thousands of miles away'.

Air or water can generate waves to carry energy, and so does plasma-the fourth state of matter- explains the release. The probe Cassini used his tool radobenko wave (RPWS) to capture the sounds of plasma waves that move between Saturn and Enceladus, reports "UKRINFORM" with reference to Science Alert.

Previously HB reported that an global group of researchers discovered complex organic molecules in the ocean on Saturn's moon Enceladus. The geologically active hotspot Enceladus emits clouds of hot vapor into the ionosphere of Saturn thereby intervening in the electrical energy of the ringed planet.

According to the lead author of the new paper published in the journal "Geophysical Research Letters", Ali Sulaiman from the University of Iowa, Enceladus has been identified as a continuous source of energy revolving Saturn and Saturn's response was recognized in the signals launched as plasma waves. The recording was converted by the RPWS team at the University of Iowa, led by physicist and RPWS Principal Investigator Bill Kurth.
