ESA shared the sound of the magnetic waves generated in the magnetic foreshock above the earth on their official Instagram page. They also asked the followers to remix the mesmerizing sound and tag them.
The Cluster mission Of ESA has recorded the magnetic waves: Watch the Video
“Open you ears and listen to Earth’s magnetic song 🧲
Our Cluster mission has recorded the magnetic waves generated in the magnetic foreshock above Earth – the first region of our planet’s magnetic environment that solar wind particles encounter – during calm space weather conditions. The audio is a ‘sonification’ of the data, where sounds were obtained by transforming the frequencies of these magnetic waves into audible signals.⠀⠀⠀⠀
The timelapse was recorded separately by @astro_paolo from the @iss during his VITA mission in 2017 while orbiting from Africa to eastern Europe.⠀⠀⠀⠀
Remix the sound of this #ESAReels and tag us in your own reels so we can see your creative takes on this sound.”

Data from ESA’s Cluster mission has provided a recording of the eerie “song” that Earth sings when it is hit by a solar storm. Cluster consists of four spacecraft that orbit Earth in formation, investigating our planet’s magnetic environment and its interaction with the solar wind—a constant flow of particles released by the sun into the Solar System.
As part of their orbits, the Cluster spacecraft repeatedly fly through the foreshock, which is the first region that particles encounter when a solar storm hits our planet. The team found that in the early part of the mission, from 2001 to 2005, the spacecraft flew through six such collisions, recording the waves that were generated.
