Scientists have revealed exactly when the next shortest days will occur as Earth's rotation speeds up once again.

Here’s what you’ll learn when you read this story: Although the Earth completes one full rotation in 86,400 seconds on average, that spin fluctuates by a millisecond or two every day. Before ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a ...

Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes influence surface habitability.

High-quality magnetic materials and assemblies – from rare earth magnet components to complex magnetic assemblies, the company's products power the most advanced technologies critical to the ...

Earth’s oxygenated atmosphere and magnetic field make life possible, but scientists have discovered that there’s a hidden link between the two that’s stronger than we originally imagined.

Study reveals that high-energy cosmic rays are born in magnetic fields during neutron star mergers, a prelude to black holes.

In 2021, researchers predicted that a geomagnetic reversal could lead to mass extinctions and climate chaos—not from the flip itself, but from the collapsing magnetic field. With Earth’s shield ...

A space physicist has suggested that a reversal of the Earth’s magnetic poles may have wiped out the Neanderthals.

The strength of Earth’s magnetic field and the amount of oxygen in its atmosphere seem to be correlated—and scientists want to know why ...
