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 ...

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 ...

A giant dent in Earth's magnetic field is continuing to expand, according to the latest data from a trio of satellites monitoring our world. It's called the South Atlantic Anomaly, stretching across ...

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 ...

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 ...

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 ...

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 ...

Here’s what you’ll learn when you read this story: The South Atlantic Anomaly (SAA) is a particularly weak region of the magnetic field stretching from South America to western Africa. Wherever the ...

High above the Sun’s blazing equator lie its mysterious poles, the birthplace of fast solar winds and the heart of its magnetic heartbeat. For decades, scientists have struggled to see these regions, ...
