Ancient rocks show Earth’s magnetic field followed deep heat patterns inside the planet for hundreds of millions of years.

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

The recent Australia Magnetic Anomaly mapping was done using regional aeromagnetic data gathered during the Northern ...

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own ...

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields from the Big Bang may offer a solution.

Earth’s magnetic field is constantly swirling and shifting thanks to a colossal ocean of liquid metal sloshing around in its ...

For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon ...

Earth’s magnetic field is easy to forget. It doesn’t make noise, it doesn’t flash, and it doesn’t ask for attention. Yet it ...

The continent-sized blobs are much hotter than the lower mantle, creating a significant temperature gradient in the rocky ...

In collaboration with international partners, researchers at the University of Stuttgart have experimentally demonstrated a ...

Yale researchers may have solved a longstanding puzzle as to why certain metallic meteorites show traces of a magnetic field — a finding that may shed light on the formation of magnetic dynamos at the ...
