Ancient volcanic rocks reveal how two giant hot regions beneath Africa and the Pacific have shaped Earth's magnetic shield.

From galaxies to the Sun, new research explains how turbulent motion can produce large-scale magnetic fields that remain ...

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 ...

An electric field transforms an iron oxide nanoparticle suspension into a model for the emergence of complex dissipative structures. Researchers at Aalto University have shown that a nanoparticle ...

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 ...
