Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

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 ...

During the Sturtian glacial period during the Neoproterozoic Era, Earth underwent periods of global glaciation, which have ...

New AI features in Google Earth let users ask chatbot-style questions to find changes in the climate. The system could eventually predict disasters and identify the communities likely to be affected.

NOAA and the University of Colorado Boulder’s CIRES have released the 2026 High Definition Geomagnetic Model (HDGM), delivering a 20% boost in resolution for mapping Earth’s magnetic field. By ...
