The magnetosphere, formed by Earth's magnetic field, acts as a protective shield that deflects solar wind—the flow of charged ...

Did ancient sunscreen and sewing needles save humanity? In a nutshell 41,000 years ago, Earth’s magnetic field weakened to just 10% of its current strength, causing auroras to appear globally ...

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 ...

It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied scientists for generations. It sits over 3,000 miles below the surface, smaller ...

At planetary scale, Earth’s magnetic field induces such a current, which regenerates the magnetic field, which induces more current, and so on in a self-sustaining process known as a geodynamo. German ...

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency ...

Eyes to the sky! More aurora displays may be on the way following a powerful solar flare and the eruption of an exceptionally ...

However, Earth’s magnetic field almost collapsed 591 million years ago, and this change, paradoxically, may have played a pivotal role in the blossoming of complex life, new research has found.
