Over 40,000 years ago, Earth’s magnetic field underwent a full reversal, a rare phenomenon in which the North and South ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

Magnetic deposits laid down during the Ediacaran Period, 630 million years ago to 541 million years ago, are not inexplicable fluctuations, some researchers argue. Instead, there is a pattern encoded ...

The sun’s surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed ...

Our Sun is far from a smooth, white ball in the sky. Twisting and looping magnetic field lines rise from its surface like hair, causing dark, transient patches on the surface called sunspots wherever ...
