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 ...

Astronomers detect radio signals directly from exoplanet Beta Pictoris b, revealing clues about its magnetic field and powerful auroras.

Exoplanet magnetic field measurement became possible for first time as astronomers used MeerKAT to detect circularly ...
