Hear the Earth's voice for the first time in human history
A scientist from the Technical University of Denmark was able to record the sound of the Earth’s magnetic field by a satellite belonging to the European Space Agency.
Earth's magnetic field is a complex and dynamic bubble that keeps us safe from cosmic radiation and charged particles carried by the powerful winds flowing from the sun. When these particles collide with atoms and molecules — primarily oxygen and nitrogen — in the upper atmosphere, some of the energy in the collisions is converted into the blue-green light that characterizes the aurora, which can sometimes be seen from higher northern latitudes.
While the aurora borealis provide a visual display of charged particles from the sun interacting with Earth's magnetic field, being able to actually hear the magnetic field generated by Earth or its interaction with the solar wind is another matter.
Our magnetic field is generated largely by an ocean of superheated liquid iron and vortex that forms the outer core about 3,000 kilometers below our feet, creating electric currents, which in turn generate our ever-changing electromagnetic field.

Launched in 2013, the European Space Agency's trio of Swarm satellites are designed to understand precisely how our magnetic field is created by precisely measuring magnetic signals that stem not only from the Earth's core, but also from the mantle, crust and oceans, as well as from the ionosphere and mantle. magnetic. y
Musician and project supporter Klaus Nielsen, from the Technical University of Denmark, explains, “The team used data from the European Space Agency's Swarm satellites, as well as other sources, and used these magnetic signals to manipulate and control the audio representation of the underlying field. The project was certainly a useful exercise in combining art and science.”
It may sound like nightmarish stuff, but, remarkably, this audio clip represents the magnetic field generated by the Earth's core and the solar storm.
“Scientists have come up with a very interesting sound system consisting of more than 30 speakers that have been dug into the ground at Solbjerg Square in Copenhagen.
“The gurgling of the Earth’s magnetic field is accompanied by a representation of a geomagnetic storm caused by the solar flare on November 3, 2011, and it really does look very scary.”
