Using data from ESA’s Swarm mission, scientists transformed this ancient phenomenon into an unsettling soundscape, offering a unique auditory glimpse into Earth’s magnetic past. Sounding the Chaos of Earth’s Magnetic FieldThe process of turning raw data into sound involved a combination of scientific mapping and creative sound design. Scientists took data that described the magnetic field lines and how they moved during the Laschamp event and…
