Earth’s molten outer core is critical to life on our planet. Churning some 2,900 kilometers beneath the surface, it’s a vast ...

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 feels permanent, but science tells a far more fragile story. Long before modern life emerged, the invisible shield protecting the planet from solar radiation weakened to a ...

Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in the final phase have now moved on to launching their satellites within the ...

The liquid iron in Earth's outer core doesn't always behave as expected. When it changed direction in an unexplained way, ESA ...

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 ...

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 ...

The same magnetic phenomenon that causes auroras on Earth has now surprisingly been discovered creating giant magnetic bubbles around Venus, a planet without a magnetic field. These findings could ...

Particle detector Calculations suggest that millicharged dark matter could be detected by observing its interaction with ...

Earth’s magnetic field has been acting restless, with the north magnetic pole racing across the Arctic and the field itself weakening in some regions. Those shifts have fueled viral claims that a ...

For all we’ve learned about places far away in outer space, we may have barely scratched the surface of the places lying deep within Earth. As a result, there’s a lot of information we seem to be ...
