Earth spins, shifts, and now… flips? Our planet’s gymnastics routine continues underneath our feet nearly every day, but researchers at the Helmholtz Centre for Geosciences in Germany recently mapped ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

Earth's magnetic field acts as a vital shield against radiation arriving from space, but it is not constant. A new ...

Earth’s magnetic field seems steady and true — reliable enough to navigate by. Yet, largely hidden from daily life, the field drifts, waxes and wanes. The magnetic North Pole is currently careening ...

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ends of the magnetosphere, which surrounds the Earth like a giant, invisible ...

A dramatic shift in Earth’s magnetic field occurred roughly 41,000 years ago during what scientists now call the Laschamps Event. Recent studies, including a detailed analysis presented at the ...

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 ...

A study on past reversals of Earth’s magnetic field has found that a rapid shift occurred within two centuries — such an event in future would increase our exposure to the Sun’s radiation that may ...

Several studies have predicted that not all geomagnetic reversals have been discovered, but it was unknown in which periods they might be hidden. Researchers led by the National Institute of Polar ...
