Listen to spooky plasma waves moving between Saturn and its moon Enceladus

Elijah Vega | 12 July, 2018, 00:38

New research data of the mission Grand Finale of the probe Cassini discovered a previously unknown interaction between Saturn and its satellite Enceladus plasma waves between them.

So, Cassini was able to capture the sounds of plasma waves that move between Saturn and Enceladus.

This is the first time that waves that travel on magnetic fields on lines directly connecting Saturn with Enceladus have been detected.

Dr. Sulaiman and colleagues then converted these recordings into a "whooshing" audio file that we can hear - in the same way a radio translates electromagnetic waves into music.

Plasma is called "the fourth state of matter" and it is not the gas, liquid or solid. At the end of the day, Cassini recognized electromagnetic waves in the sound recurrence extend - and on the ground, we can open up and play those signs through a speaker.

Plumes of water vapor that spurt from Enceladus interact with Saturn's magnetic field, according to NASA and the Jet Propulsion Laboratory at the California Institute of Technology.

Djokovic prevails over Nishikori to reach Wimbledon semifinals
Asked whether he was a "man on a mission" to get back to where he left off, the Serb could only agree: "Of course, that's why I'm here", he said.

These particular intense plasma waves were detected during Cassini's one of the closest encounters to Saturn and picked up by spacecraft's Radio Plasma Wave Science (RPWS) instrument.

NASA's Glen Nagle says the Earth also sings to our moon - but there isn't much evidence the moon sings back. "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". Comparable associations happen amongst Saturn and its rings, as they are additionally extremely powerful. Scientists have turned these signals into audio and accelerated it with 16 minutes to 28.5 seconds.

Sulaiman is lead author of a pair of papers describing the findings, published recently in Geophysical Research Letters.

While we know that there is no "sound" as such traveling between Saturn and Enceladus since that would require air, radio waves can and do travel through space, and we are able to pick up plasma waves from probes like Cassini.

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.
