Hear the sounds of Earth's magnetic field from 41,000 years ago
Scientists recreate haunting sound of Earth's 'Laschamp Event' from more than 41,000 years ago.
In a recent study released on Oct. 10 by the European Space Agency, researchers from the German Research Centre for Geosciences and the Technical University of Denmark created a soundscape visualization of the Laschamp event by mapping the previous movements of Earth's magnetic field lines. According to NASA, the Laschamp event, occurred about 41,000 years ago, which caused a short reversal of Earth's magnetic field. “The team used data from European Space Agency’s Swarm satellites, as well as other sources, and used these magnetic signals to manipulate and control a sonic representation of the core field.
