Earth’s magnetic field has flipped about 170 times in the last 100 m years, and the next reversal is not a matter of if but when. Far from a cinematic instant catastrophe, a flip would unfold over ...

Earth’s magnetic field, the invisible barrier that deflects solar radiation and makes surface life possible, is not permanent in its current orientation. Geologic records show that magnetic north and ...

Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes itself over thousands of years before settling again. For decades, researchers ...

Long before life thrived in Earth’s oceans, the planet’s magnetic field became disorganized. Deep within the ancient rocks of Morocco, scientists have recovered one of the clearest records of that ...

Hundreds of millions of years ago, Earth’s magnetic field behaved in a way that has long baffled scientists, showing wild and seemingly chaotic shifts unlike anything seen before or since. A new study ...

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

Simulations and satellite data reveal that Earth's magnetic field is more complex than scientists had thought. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...
