Earth’s magnetic field acts as a protective shield, deflecting dangerous solar radiation and helping make life possible on the planet. But scientists know that throughout history the planet’s magnetic ...

Scientists discover that the Earth's magnetic poles can take up to 70,000 years to reverse, much longer than previously ...

Something massive is happening beneath your feet right now, and most people have absolutely no idea. Earth's magnetic field, ...

Earth is a giant bar magnet, and its north and south poles have been quietly swapping places over eons, scrambling what compasses would point to, if a.

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 ...

Japanese researchers say they are closing in on the mystery of Earth’s “missing” geomagnetic polarity reversals, identifying where they believe scientists should look for evidence of their unusual ...

Two vast, mysterious blobs of hot rock around Earth’s core may have been instrumental in producing Earth’s magnetic field and caused it to be slightly wonky for millions of years. Scientists have ...

Earth’s magnetic field comes from the restless motion of molten metal in the planet’s outer core. It’s our invisible shield, and it’s also surprisingly changeable. Every so often, the field ...

Earth’s magnetic field is often treated as a steady planetary shield, but geological records reveal a far more dynamic and variable system. New research examining ancient ocean sediments suggests that ...

Earth’s magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...
