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 ...

Earth’s magnetic field feels permanent, but science tells a far more fragile story. Long before modern life emerged, the invisible shield protecting the planet from solar radiation weakened to a ...
