Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...

A rare magnetic phenomenon, once thought confined to the sun’s outer atmosphere, has been seen to twist its way through Earth ...

Though you might think that compasses will always point towards the geographic north pole, the magnetic and geographic poles do not always align. As well as a few temporary reversals, the Earth's ...

Ever seen the northern lights? You have a magnetic layer in Earth’s atmosphere to thank for those beautiful displays. But the magnetosphere does a lot more than create auroras.

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

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 ...
