Between Earth and the Sun, space is not truly empty but is filled with a soup of charged particles called plasma. This plasma comes from the Sun, pumped out in a steady stream called the solar wind and sporadically blasted away in explosive solar eruptions. When this solar plasma strikes Earth, it causes the magnetic field lines and plasma around Earth to vibrate like the plucked strings of a harp, producing ultralow-frequency waves.

In 2007, NASA launched five satellites to fly through Earth’s magnetic “harp” – its magnetosphere – as part of the THEMIS mission (Time History of Events and Macroscale Interactions during Substorms). Since then, THEMIS has been gathering a bounty of information about plasma waves across Earth’s magnetosphere. 

The frequencies of the waves THEMIS measures are too low for our ears to hear, however. So a NASA citizen science project called HARP – or Heliophysics Audified: Resonances in Plasmas – has sped up the waves recorded by THEMIS to convert them to sound waves.

In this clip from March 2-5, 2012, whistle sounds are repeatedly heard over ambient background whooshes and crunches. The whistles change in pitch as a THEMIS spacecraft moves toward and away from Earth on three orbits, with a maximum altitude of about 50,000 miles. These sounds are related to Earth’s magnetic harp, which has longer magnetic strings and lower pitches farther away from Earth. These three orbits happened when the solar wind was relatively quiet, but it’s still able to pluck the strings of Earth’s magnetic harp while also causing many other types of magnetic vibrations, most of which sound like background whooshes and crunches.

Grave Height River (Local Classic)

Brief excerpt from a recording actually made during dawn on Friday 2nd May 2025, because the weather was perfect, and because I could get out there; whereas the forecast for Sunday 4th May wasn't as good, and I couldn't get out there that day. Raw recording. Just a friendly postcard from the other pole, where it's not spring, but on the way to winter. (They say 'Down Under': but, of course, there is no 'up' or 'down' in Space.)

2025.05.02 For the Northern Hemisphere's 'Dawn Chorus Day', from the Southern Hemisphere.

This is Prurient's set from the "Fun From None" DVD on Load Records. Feedback sirens forcefully rape the ears of the listener and make them submit to their rage. Enjoy your downward spiral! Filmed by Chris Habib.
