Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

Sometimes the geologic record obscures evidence of these important reversals in field direction, but statistical techniques ...

Earth's magnetic field exhibits a significant weakening in the South Atlantic Anomaly, a region expanding and becoming more ...

Researchers have identified a period of sluggish magnetic field flipping for planet Earth, some 40 million years ago – raising big questions about how long these reversals actually take, and how we ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

Webb has delivered the first detailed 3D view of Uranus’s upper atmosphere, uncovering glowing auroras, heat peaks thousands of kilometers high, and the powerful influence of its tilted magnetic field ...

The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM spectrum ...

A lab in China has produced the most powerful steady magnetic field in the world. The Steady High Magnetic Field Facility (SHMFF) in Hefei, China, recorded a field strength of 45.22 Tesla (T) on ...
