Laut ESA ziemlich genau so. „The result is pretty scary.“ Das will ja quasi gesamplet werden.
Launched in 2013, ESA’s trio of Swarm satellites are being used to understand exactly how our magnetic field is generated by measuring precisely the magnetic signals that stem not only from Earth’s core, but also from the mantle, crust and oceans, as well as from the ionosphere and magnetosphere. Swarm is also leading to new insights into weather in space.
Musician and project supporter Klaus Nielsen, from the Technical University of Denmark, explains, „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.“
It might sound like the stuff of nightmares, but, remarkably, this audio clip represents the magnetic field generated by Earth’s core and a solar storm.
