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

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

When trying to identify the nature of dark matter, sometimes it’s the things it doesn’t do that tell us the most, like ...

The weak spot, known as the South Atlantic Anomaly, was identified in the 19th century and expanded in recent years.

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have ...

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

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

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

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

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 ...

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 ...

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 ...
