Listen to haunting sounds of Earth’s magnetic field flipping 41,000 years ago in eerie new animation

An exciting brand-new video clip shows how Earth’s magnetic field went crazy and nearly completely disappeared during our planet’s newest “polar turnaround occasion,” around 41,000 years earlier. A haunting soundscape of “alien-like” squeaking noises highlights the pressure placed on our world’s unseen protective shield.

The last time this took place was around 41,000 years earlier, when the magnetosphere all of a sudden deteriorated and briefly flipped over the program of numerous centuries. Evidence of this geomagnetic trip, known as the Laschamp occasion, can be found in ancient lava flows, which consist of abnormally high ratios of particular isotopes brought on by boosted degrees of planetary rays. Past research study right into fossilized tree rings likewise exposed that the magnetosphere was minimized to around 5% of its current strength, enabling solar radiation to paint auroras across the equator.

“The procedure of changing the sounds with information resembles making up music from a score,” the researchers wrote in a statement. Instead of utilizing musical tools, the team utilized recordings of natural noises, such as wood creaking and rocks falling, to create strange “alien-like audios.”

The brand-new video clip, launched Oct. 10 by the European Room Company (ESA), shows how magnetic-field lines within the magnetosphere deformed and damaged during the Laschamp occasion. The animation, which covers around 3,000 years, was developed utilizing data from ESA’s Throng goal, a trio of satellites that have actually been keeping an eye on the magnetosphere because 2013. The information also assisted the scientists create a disturbing “soundscape” to accompany the video, which highlights the enormous pressure placed on the magnetosphere during the occasion.
