In other words, Cbadini has detected electromagnetic waves in the audio frequency range – and in the field, we can amplify and play these signals through a loudspeaker . The recording time was compressed from 16 minutes to 28.5 seconds
Just like air or water, plasma (the fourth state of matter) generates waves to carry l & # 39; energy. The Plasma Wave Science Instrument (RPWS) instrument aboard NASA's Cbadini spacecraft recorded intense plasma waves at one of its closest encounters with Saturn
"Enceladus is this little generator around Saturn and we know that it is a source of continuous energy, "said Ali Sulaiman, a planet scientist at the University of Iowa, Iowa City, and a member of the University of Iowa. RPWS team. "Now we find that Saturn responds by throwing signals in the form of plasma waves, through the circuit of magnetic field lines that connect it to Enceladus hundreds of thousands of kilometers away."
Sulaiman is the principal author of a pair of papers describing the results, published recently in Geophysical Research Letters.
The interaction of Saturn and Enceladus is different from the relationship of the Earth and its Moon. Enceladus is immersed in the magnetic field of Saturn and is geologically active, emitting plumes of water vapor that ionize and fill the environment around Saturn. Our own Moon does not interact in the same way with the Earth. Similar interactions take place between Saturn and its rings, because they are also very dynamic.
The recording was captured on September 2, 2017, two weeks before Cbadini was deliberately immersed in the atmosphere of Saturn. The recording was converted by the RPWS team from the University of Iowa, led by physicist and principal investigator of the RPWS, Bill Kurth.

The Cbadini-Huygens mission is a cooperative project of NASA, ESA (European Space Agency) and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, manages the mission of the NASA Science Missions Directorate in Washington.
The JPL designed, developed and badembled the Cbadini orbiter. The RPWS instrument was built by the University of Iowa, in collaboration with members of the United States and several European countries

<p> The observations show for the first time that the waves travel on magnetic field lines connecting Saturn.The field lines are like an electrical circuit between the two bodies, the circu energy lant back and forth. </p>
