When the magnetic field around the Earth grows stronger, oxygen levels rise. That is the surprising finding of a new study looking at more than half a billion years of planetary history. Researchers ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are ...

As with any such correlation, one has to entertain the notion that said correlation might be spurious or indirectly related before assuming a strong causal link. Here it is for example known already ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

Earth's magnetic field dramatically flipped roughly 41,000 years ago. We can now experience this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...

Earth’s magnetic field seems steady and true — reliable enough to navigate by. Yet, largely hidden from daily life, the field drifts, waxes and wanes. The magnetic North Pole is currently careening ...

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency, researchers ...

Rocks in West Greenland resemble cake marbled with chocolate and vanilla. They’re now the oldest evidence of Earth’s magnetic field. Isua Supracrustal Belt rocks contain an alternating banded iron ...
