The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

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 ...

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through ...

It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a ...

Scientists discovered Earth’s magnetic field is weakening over the Atlantic Ocean, but what does that mean for life on the ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

Earth’s core dynamics and conductivity underpin the generation and evolution of the geomagnetic field, influencing the thermal history and long‐term sustainability of the geodynamo. Studies over ...

Previous calculations have suggested that 800-1000 °C of supercooling would be needed to initiate freezing of the core if it were made of pure iron. However, if the core is supercooled to this degree, ...

Deep inside Earth, researchers see signs that the solid inner core may be arranged in multiple chemical layers far below.

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

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 ...

The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in the direction of Africa over the past decade. When you purchase through ...
