Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity flips, when magnetic north and south swap places, happen several times per ...

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

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

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

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

The sun’s surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

Most of the time, the shape of Earth’s magnetic field is quite similar to that which would be produced by a bar magnet ...

For decades, scientists have suspected the presence of a magnetic field that holds the Milky Way together, but only now has ...

Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun's outermost layers. If confirmed, the findings could help scientists better predict space ...
