Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

For decades, scientists have been trying to understand why some rocks on the moon are strongly magnetized even though the moon has no magnetic field today. "The majority of the strong magnetic fields ...

From galaxies to the Sun, new research explains how turbulent motion can produce large-scale magnetic fields that remain ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields ...

Explorers have long trusted compasses to navigate Earth's land and oceans, using our planet's global magnetic field as their ...

In A Nutshell Two massive hot regions deep beneath Africa and the Pacific Ocean have been influencing Earth’s protective ...

Our Sun is far from a smooth, white ball in the sky. Twisting and looping magnetic field lines rise from its surface like hair, causing dark, transient patches on the surface called sunspots wherever ...

When will the pole shift happen? Researchers say it's definitely a matter of when and not if. The poles have shifted in the past and will likely do so again. When the pole shift occurs, it will happen ...

A new model contradicts previous theories that the sun's magnetic field originates deep inside its interior. Deep origin theories could not explain rotation patterns of the sun's gas near its surface ...
