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

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

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 ...

Fish, birds, reptiles, amphibians, and even a few mammals rely on magnetoreception for navigation. But the exact mechanism ...

Two enormous, supercontinent-sized 'islands' buried deep within the mantle have been revealed to have fundamental differences—contrary to previous assumptions—and they may even lead to Earth's ...

In the blink of an eye in geological time, Canada has lost one north pole but gained another, a new and different claim to be ...

The solar wind flows around Earth's magnetic field. A new NASA study suggests that the amount of oxygen in the atmosphere and strength of the magnetic field have been correlated for more than half a ...

Earth’s magnetic north pole has shifted toward Russia, prompting updates to GPS and navigation systems worldwide. Scientists track this invisible movement to keep technology accurate.

External sources, such as the early solar wind or Earth’s magnetic field, were too weak or faded too early. Internal sources like a magma ocean or mantle-core precession might have helped, but ...

Neanderthals have long been the subject of intense scientific debate. This is largely because we still lack clear answers to some of the big questions about their existence and supposed disappearance.

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...
