Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are ...

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

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain unresolved. A team of researchers from the Center for Advanced Systems ...

Earth's magnetic field dramatically flipped roughly 41,000 years ago. We can now experience this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

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 ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

A tree-ringed African lake has yielded a record of Earth's magnetic field spanning the past 150,000 years. A core of rock and sediment drilled from the bottom of Lake Chala, a picturesque crater lake ...

Earth’s magnetic north pole has shifted toward Russia, prompting updates to GPS and navigation systems worldwide. Scientists track this invisible movement to keep technology accurate.
