Name: Cassini: Saturn Radio Emissions #1 by NASA in Spooky Sounds from Across the Solar System
Duration: 19 s
Description: Saturn is a source of intense radio emissions, which were monitored by our Cassini spacecraft. The radio waves are closely related to the auroras near the poles of the planet. These auroras are similar to Earth's northern and southern lights. This is an audio file of radio emissions from Saturn.

Soaring to the depths of our universe, gallant spacecraft roam the cosmos, snapping images of celestial wonders. Some spacecraft have instruments capable of capturing radio emissions. When scientists convert these to sound waves, the results are eerie to hear.

In time for Halloween, we've put together a compilation of elusive "sounds" of howling planets and whistling helium that is sure to make your skin crawl.

Spooky Sounds from Across the Solar System

Saturn’s ocean-bearing moon also bears some spooky sounds! Here’s one captured by our Cassini spacecraft.

Before settling into orbit around Saturn, Cassini faced a white-knuckle ride through the plane of the planet’s rings. When converted into an audio file, the interstellar cacophony is reminiscent of a hellstorm on Earth.

Cassini Shields Up

These melodious tones are created at a special frequency in a plasma with a magnetic field. The frequency is set by the number of electrons in a given volume (the electron density) and the strength of the magnetic field. Hence, the frequency of these waves, called upper hybrid waves, can provide a very accurate measure of the density of the plasma; a fundamental property of the Jovian environment of interest to scientists. These emissions were acquired by Voyager 2 as it passed through the outer magnetosphere in 1979.

Voyager Plasma Sounds

New research from the up-close Grand Finale orbits of NASA’s Cassini mission shows a surprisingly powerful interaction of plasma waves moving from Saturn to its moon Enceladus. Researchers converted the recording of plasma waves into a “whooshing” audio file that we can hear -- in the same way a radio translates electromagnetic waves into music. Much like air or water, plasma (the fourth state of matter) generates waves to carry energy. The recording was captured by the Radio Plasma Wave Science (RPWS) instrument Sept. 2, 2017, two weeks before Cassini was deliberately plunged into the atmosphere of Saturn.

Sounds of Saturn: Hear Radio Emissions of the Planet and Its Moon Enceladus

The Stanford Experimental Physics Lab sonified data from the European Space Agency and NASA's Solar and Heliospheric Observatory (SOHO). This humming sound captures the Sun’s natural vibrations and provides scientists with a concrete representation of its dynamic movements.

Sun Sonification

Using data from NASA's THEMIS mission, scientists have discovered that when the magnetopause -- the outer boundary of Earth's protective magnetic field -- is struck by a jet of plasma from the Sun, it vibrates like a drum. Waves echo back and forth along its surface, much like they do on top of a drumhead.  Read the full story: https://go.nasa.gov/2RUS7Le
