Earth’s magnetic field nearly vanished in a terrifying close call
Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...
An illustration of what the aurora might have looked like during a polar reversal about 41,000 years ago. Earth’s magnetic field is created by its rotation, as well as the rotation of our planet’s ...
During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...
