A vast, magnetically tangled sunspot has rotated into direct view of Earth, raising the prospect of powerful solar eruptions ...

On Earth, hurricane season isn’t just surface level. The ionosphere, an upper layer of the atmosphere charged by solar radiation, also contains swirling storms of plasma dubbed “space hurricanes.” ...

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 dramatically flipped a little more than 40,000 years ago. We can now experience this upheaval as an unnerving clatter interpreted from information collected by the European ...

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 ...

Life on Earth may exist thanks to a brief faltering in our planet's protective magnetic field shell, scientists have found. A bizarre drop in the strength of the magnetic field has been found to have ...

Every new generation of eyes sees a new version of our galaxy, the Milky Way. This Impressionistic swirl of color represents the churning magnetic fields in giant dust clouds near the center of the ...

Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...
