Long before life thrived in Earth’s oceans, the planet’s magnetic field became disorganized. Deep within the ancient rocks of ...

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 ...

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have discovered that the weak region in Earth's magnetic field over the South ...

A major dip in the Earth’s magnetic field over the South Atlantic has been puzzling scientists for over a century. An international team of researchers analyzed data collected by the European Space ...

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 ...

Satellite data reveal that a weak region in Earth's magnetic field has grown by an area roughly half the size of continental Europe in the last 10 years. A weak region in Earth's magnetic field has ...

The magnetic barrier that protects Earthlings from radiation almost collapsed some 565 million years ago. Here’s what saved it. Those millions of dead people supposedly claiming Social Security? It’s ...

Based on the grazing view, the general consensus was that the plasma cells and the magnetic field shifted poleward more slowly than at the equator. But Solar Orbiter has shown that the speed is higher ...

Scientists have discovered that a 'weak spot' in Earth's magnetic field is growing at an alarming rate. Known as the South Atlantic Anomaly (SAA), the region has expanded by an area nearly twice the ...

A weak spot in the Earth's magnetic field is growing over the South Atlantic Ocean, according to more than a decade's worth of satellite data collected by scientists. The magnetic field surrounding ...
