However, our understanding of planetary magnetic fields is limited to the eight planets in our solar system, as we haven't yet accrued much data on the magnetic fields of exoplanets. That could be ...

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...

The Sun’s magnetic field is invisible to our eyes, but it quietly shapes everything from the shimmering auroras over the ...

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic field?

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...

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 ...
