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.

Following a run of chamber recordings, Samuel Reinhard returns with a suite of electroacoustic collages. 

"Movement", the New York–based composer’s latest offering, is built from notes softly held. In his ongoing investigation of musical duration, perception, and attention, Reinhard deemphasizes progress through an embrace of repetition and negative space, inviting listeners to linger in time. Instrumental recordings are arranged according to a predetermined system, iterating fragments of sound in overlapping intervals of various sizes. Delicately layered snippets of decaying piano are joined by cello (Leila Bordreuil), bass flute (John Also Bennett), double bass (Vincent Yuen Ruiz), baritone sax (Michael Biel), and harp (Shelley Burgon). This breadth of instrumentation, arriving as individual notes stretched and overlapped, is treated not as an opportunity for immersive coalescence, but rather a gentle augmentation of texture, free-floating counterpoint. Notes are accompanied by the traces of the bodies and actions that produce them: a hand pressing a key or an arm keeping a bow aloft; breath filling an instrument’s body or glancing off its surface; a string vibrating and then softening to stillness. In sum, we hear resonance in the process of being sustained, as well as in the release that follows.

Movement is a joint release from Hallow Ground and Präsens Editionen, and follows offerings by Kali Malone, Lawrence English, and FUJI||||||||||TA  on Hallow Ground, and Robert Turman, Magda Drozd, and Anna Homler on Präsens Editionen.

Plasmawaves - Chorus

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.

Aphex Twin - 21 Forgotten T

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.
