The South Atlantic Anomaly (SAA), a known region of Earth’s magnetic field weakness, has been under the observation of the ...

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

The weak spot, known as the South Atlantic Anomaly, was identified in the 19th century and expanded in recent years.

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 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 ...

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 ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...
