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

Some bacterial species possess an astonishing ability: They use Earth's magnetic field to orient themselves. To better understand this mechanism, the team led by Argovia-Professor Martino Poggio from ...

A sediment core from the North Atlantic has revealed that one ofEarth’s magnetic field reversals during the Eocene lasted far ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

Scientists at the University of Oxford have finally settled a decades-long mystery about the Moon’s magnetic field — and it turns out both sides were right. By reanalyzing Apollo mission rocks, they ...
