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 ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

Apollo moon rocks show the Moon had short bursts of strong magnetism, not a long lasting magnetic field, changing how we ...

Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun's outermost layers. If confirmed, the findings could help scientists better predict space ...
