The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in ...

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

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 ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

As they whirl around in low-Earth orbit, satellite configurations are far more sensitive to changes in Earth's gravity field ...

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

The South Atlantic Anomaly (SAA) is a particularly weak region of Earth’s magnetic field that can cause satellites to ...

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 ...

A giant dent in Earth's magnetic field is continuing to expand, according to the latest data from a trio of satellites ...

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 ...
