The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Researchers have identified a period of sluggish magnetic field flipping for planet Earth, some 40 million years ago – ...

Protective force fields exist and you’re already living inside one. About 1,800 miles beneath the ground you’ll reach the border of Earth’s outer core, a subterranean ocean of liquid iron and nickel 1 ...

A surprising observation has recently highlighted a close relationship between our planet's magnetic field and the oxygen content of its atmosphere. Over more than half a billion years, these ...

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of years. Using ancient magnetic records and advanced simulations, scientists ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

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

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 ...
