NASA launches TRACERS satellites to reveal how solar energy penetrates Earth's magnetic shield and triggers space storms.

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...

A view of the center of our galaxy shows the Sagittarius C (Sgr C) region, where cold dust (magenta) and warmer gas and dust (cyan) surround a cluster of massive stars. The stars generate high-speed ...

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 ...

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 ...

How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery" operating ...

In 2008, Erez Ben-Yosef unearthed a piece of Iron Age "trash" and inadvertently revealed the strongest magnetic-field anomaly ever found. Ben-Yosef, an archaeologist at Tel Aviv University, had been ...

If our planet flips and no one’s around to hear it, does it still make a sound? Scientists have managed to put a chilling soundtrack to the flipping of Earth’s magnetic field — and the result is ...

The vestibular system, a set of structures in the inner ears that helps with balance, may grant the birds their special ...
