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

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

Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...

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

Add Yahoo as a preferred source to see more of our stories on Google. Earth's Flipping Magnetic Field Heard as Sound Is an Unforgettable Horror In 2024, researchers transformed readings of an epic ...

A team of geologists found for the first time evidence linking regions of low seismic velocity and the shape of the Earth’s magnetic field.

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of ...

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 ...

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

Hidden mega-structures deep inside Earth may have been quietly steering our planet’s magnetic field—and rewriting what we thought we knew about Earth’s past.

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

Some bacterial species possess an astonishing ability: They use Earth's magnetic field to orient themselves. To better understand this mechanism, the team led by Argovia-Professor Martino Poggio from ...
