This recording resembles a lot first minutes of "Velvet Voyage" from 1977 album "Mirage" by Klaus Schulze.

Sampling it for à Dark Ambient track would sound perfect to me ahah

The joint ESA/Jaxa BepiColombo mission flew past Mercury for the first time on 1 October 2021, capturing data with the magnetometer onboard ESA’s Mercury Planetary Orbiter. A sonification of the magnetic field data is presented here.  
 
Two synthesizers can be heard, which are controlled by three characteristics of the magnetic field. The first synthesizer's pitch represents the slowly changing magnitude of the background magnetic field. First the solar wind is heard, then the increase and decrease of the planetary magnetic field, and then the solar wind again. The lower the pitch, the more intense the magnetic field. 
 
The pitch of the second synthesizer is controlled by the variations of the magnetic field magnitude. A more turbulent magnetic field is represented by a faster change in pitch. The magnetosheath crossing after closest approach is very prominent. 
 
Using the amplitude envelope as a control for the volume of the second synthesizer emphasises the different magnetospheric regions.

Sound of the solar wind at Mercury

NASA’s InSight lander brought a seismometer to the Red Planet to study “marsquakes.” On Sept, 5, 2021, the seismometer detected a meteoroid impacting the planet’s surface, creating several craters in the process.
It was the first time the sound of a meteoroid impact was captured occurring on another planet, and it might not be what you expect. In the audio, you hear three “bloops” representing distinct moments of the impact: the meteoroid entering Mars’ atmosphere, exploding into pieces, and striking the ground. The peculiar sound is caused by an atmospheric effect that’s also been observed in deserts on Earth, where lower-pitched sounds arrive before high-pitched sounds.

InSight Captures Sound of a Meteoroid Striking Mars

Despite being essential to life on Earth, the magnetic field isn’t something we can actually see in itself, or ever hear. But, remarkably, scientists at the Technical University of Denmark have taken magnetic signals measured by ESA’s Swarm satellite mission and converted them into sound – and for something that protects us, the result is pretty scary.

The scary sound of Earth’s magnetic field

This sonification is of the signals recorded by NASA’s InSight Mars lander, which detected a giant meteoroid strike on Dec. 24, 2021, the 1,094th Martian day, or sol, of the mission. InSight’s seismometer records seismic signals that are not in the range of human hearing. In order to make the signals audible, the data was sped up 100 times.

NASA’s InSight Records the Sound of a Martian Impact

One year ago, the Hunga Tonga-Hunga Ha’apai volcano erupted, causing widespread destruction to the Pacific Island Nation of Tonga. It spewed volcanic material up to 58 km into the atmosphere, brought a nearly 15 m tsunami that crashed ashore, destroying villages, and created a sonic boom that rippled around the world – twice. 

Even one year on, interest in the extraordinary explosive eruption remains. A sound artist has recently recreated the sonification of the underwater volcanic eruption using rayleigh signal intensity data provided by the Aeolus Virtual Research Environment platform.

Using wind data obtained on one of its overpasses over the ash cloud of the Hunga Tonga explosion, Jamie Perera used an audio sample of one of the shock waves, time-stretched it into a ghostly tone, and assigned it to harmonic values transcribed from 90 Aeolus readings taken over a duration of approximately 15 minutes. 
The listener hears one reading every two seconds, in a harmonic range that spans six piano octaves, the highest of which can be heard at around 01:18 minutes when the readings show the eruption’s dust plume at its highest peak (over 20.5 km). The artistic intention behind the sonification was to evoke the otherworldly landscape of Hunga Tonga and other volcanoes.

Sound of the Hunga Tonga Volcanic Eruption

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 February 21-22, 2012, whistle sounds are repeatedly heard over ambient background whooshes and crunches. The whistles decrease and increase in pitch as a THEMIS spacecraft moves toward and away from Earth on one orbit, 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.

In this clip from March 19-20, 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 one orbit, with a maximum altitude of about 50,000 miles. These sounds are related to Earth’s magnetic harp. We normally expect the whistles to have lower pitches farther away from Earth where the harp strings are longer, but the first part of this clip goes against this trend: the pitch increases or stays the same as the satellite moves away from Earth. 

 Thanks to volunteers on the HARP project who uncovered this pattern, researchers are now able to study these unusual vibrations and their connection to space weather.

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 blowing past Earth at a speed of about 1,200,000 miles per hour, which is fast even by solar wind standards! There’s often more harp activity during fast solar wind conditions. The solar wind also causes many other types of magnetic vibrations, most of which sound like background whooshes and crunches.

Instant Tranquility Tune-Up: Music for Immediate Peace

Another gem from the ESA archives: 

Tracks left behind by the November 2000 Leonids shower, as detected by ESA scientists.

Each time a meteor crosses the atmosphere, it leaves behind a short trail of ionised particles. This trail reflects high-frequency radio signals from stations around the world for just a few seconds. The motion of the meteor trail due to the upper atmosphere winds changes the frequency of the reflected signal (Doppler effect). You 'hear' the trail as it is blown around by the winds before it is eventually dispersed.
