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 ...

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

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 ...
