Sound of electromagnetic energy moving between saturn, enceladus

The perceptions appear out of the blue that the waves travel on magnetic field lines interfacing Saturn straightforwardly to Enceladus. It is similar to electromagnetic waves that can be translated into music and amplified and played through a speaker. (And ours.) We now know that Cassini also recorded a soundtrack of sorts-data that has now yielded a series of thrillingly eerie whooshes and warbles that represent the relationship between the ringed planet and Enceladus, one of its moons.

Air or water can generate waves to carry energy, and so does plasma-the fourth state of matter- explains the release.

Previously HB reported that an global group of researchers discovered complex organic molecules in the ocean on Saturn's moon Enceladus.

"We have now discovered that Saturn responds to perturbations from its companion in the form of waves in plasma, using the contour lines of the magnetic field, linking it to Enceladus, at a distance of hundreds of thousands of kilometers away", said one of the researchers Ali Suleiman.


Enceladus is immersed in Saturn's magnetic field and is geologically active, emitting plumes of water vapor that become ionized and fill the environment around Saturn. Our own Moon does not collaborate similarly with Earth. Now NASA has compressed the audio time to 28.5 seconds, and decreased the wave frequency by a factor of 5, and you can conveniently tune in on your computer.

The "circuitry" between the planet and its moon is the subject of two recent papers in the journal Geophysical Research Letters.

Saturn isn't just a handsome planet with its distinct set of rings, it's also a giant electric generator.

The recording was captured by the Radio Plasma Wave Science (RPWS) instrument September 2, 2017, two weeks before Cassini was deliberately plunged into the atmosphere of Saturn. The recording was converted by the RPWS team at the University of Iowa, led by physicist and RPWS Principal Investigator Bill Kurth. The RPWS instrument was built by the University of Iowa, working with team members from the USA and several European countries.
