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 ...

Regularly—at least in the geological sense—Earth’s magnetic field flips. In plain English: the magnetic North Pole heads to the South, while the South Pole pays a visit up north. This has happened, on ...

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 ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

Deep inside the planet, the churning of molten iron generates a magnetic field that shields the surface and guides every ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation. For at least 4 billion years, an invisible force field has enveloped our planet ...
