The Earth's magnetic field has been getting weaker over the past few centuries. This weakening can be seen in data gathered ...

Recent research has revealed a surprising discovery about Earth’s magnetosphere that challenges long-standing theories, ...

Recent research has revealed that Earth’s core is undergoing a slowdown in its rotation, a phenomenon that has piqued the interest of scientists around the world. Understanding the causes and ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and ...

As early as 2024, scientists from the US and China discovered that the Earth’s core had slowed down and even stopped moving in relation to the Earth’s crust. But until now, the general public—that’s ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

What is the speed and timing of the Earth’s inner core cooling? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated the composition ...

New satellite data show Earth’s magnetic field changing fast, with a growing weak spot over the South Atlantic.

Learn about the growth of the South Atlantic Anomaly, a region where Earth's magnetic field has significantly weakened.

We know the temperature of Earth ’s inner core is very roughly about 5,000 Kelvin (K) (4,727°C). It was once liquid, but has cooled and become solid over time, expanding outwards in the process. As it ...

CAPE CANAVERAL, Fla. — Scientists revealed Wednesday that Mars’ innermost core appears to be a solid hunk of metal just like Earth’s. The Chinese-led research team based their findings on seismic ...
