Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and ...

The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in ...

Earth’s magnetic field is essential to life on our planet. It protects Earth from cosmic radiation and acts as a shield ...

Researchers have created DNA-like magnetic nanostructures that form strong inter-helix magnetic bonds. These produce topological textures in the magnetic field, opening the door to the next generation ...

The Swarm satellites of the European Space Agency have tracked the grown of a weak spot in the magnetic field of the Earth.

Our Sun is far from a smooth, white ball in the sky. Twisting and looping magnetic field lines rise from its surface like hair, causing dark, transient patches on the surface called sunspots wherever ...

The sun’s surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed ...
