You’ve heard sounds of the sea, now check out what Earth’s magnetic field sounds like from space. Technical University of Denmark scientists took magnetic signals measured by ESA’s Swarm satellite mission and transformed them into sound. Our planet’s magnetic field is basically a complex and dynamic bubble that protects us from cosmic radiation and charged solar wind particles.
As these charged solar wind particles collide with atoms and molecules (oxygen + nitrogen) in the upper atmosphere, some of this energy is converted into the green-blue light that is typical of the aurora borealis. When this is turned into sound, you get this slightly creepy soundtrack that represents the magnetic field generated by Earth’s core and its interaction with a solar storm.

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 field. The project has certainly been a rewarding exercise in bringing art and science together,” said Klaus Nielsen, Musician and project supporter from the Technical University of Denmark.
