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

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 ...

For desert ants, Earth’s magnetic field isn’t just a compass: It may also sculpt their brains. Stepping outside their nest for the first time, young ants need to learn how to forage. The ants train ...

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 ...

When the sun reaches its period of peak activity, known as solar maximum, our star's magentic field will suddenly reverse. But why does it happen, and will it impact Earth? When you purchase through ...

How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery" operating ...

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...
