“Nightmare”: Scientists achieve a sound representation of the Earth’s magnetic field

Earth ‘s magnetic field that protects us from cosmic radiation and charged particles streaming in from the Sun.


This essential part of our planet cannot be seen or heard…until now.

The European Space Agency (ESA) published the result of the work of scientists at the Technical University of Denmark, giving us a clue as to what the Earth’s magnetic field sounds like.

Sounds of the Earth’s magnetic field: How was this achieved?

The scientists used magnetic signals measured by ESA ‘s Swarm satellite mission to produce these sounds.

“The team used data from ESA ‘s Swarm satellites , as well as other sources, and used these magnetic signals to manipulate and control a sonic representation of the core. The project has been a successful exercise in bringing art and science hand in hand,” Klaus Nielsen, a musician and project collaborator at the Technical University of Denmark , told ESA .

Sound of a “nightmare”

The ESA notes that these sounds seem “out of nightmares”, but incredibly represent the magnetic field generated by the Earth’s core and a solar storm.

The sounds reflect a geomagnetic storm produced by a solar flare on November 3, 2011.

If you are lucky enough to be in Solbjerg Square in Copenhagen, you will be able to listen to these sounds during this week from October 24 to 30 at three times: 08:00 and 13:00 and 19:00.
