👉When the Sky Glowed Everywhere — The Laschamp Event 🌍✨ About 41,000 years ago, Earth went through a powerful magnetic shift known as the Laschamp geomagnetic excursion. During this rare event, our planet’s magnetic field dropped to only 10% of its normal strength. The magnetic poles swung wildly — drifting close to Africa and Australia — which caused Earth’s protective magnetic bubble, the magnetosphere, to shrink dramatically. With less protection from space radiation, brilliant auroras fill
