A major solar storm has been pummeling Earth's magnetic field Thursday, raising the risk of power grid problems and satellite ...

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 ...

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 ...

Earth’s Magnetic Field. Credit: NASA Goddard Space Flight Center / Flickr / CC BY 2.0 A weak zone in Earth’s magnetic field, known as the South Atlantic Anomaly, has expanded at an alarming rate over ...

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 ...

The magnetic field that protects our planet is shifting – and one region is fading fast. Over the South Atlantic, a weak spot in Earth’s magnetic shield has grown steadily since 2014. It now stretches ...

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 ...

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 ...

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 ...

The Sun looks like a warm yellow sphere with a surface covered with glowing messy hair. The yellow glow extends to the edges of the image, with some regions brighter than others. Many bright yellow ...
