HEFEI -- Chinese and international scientists have, for the first time, discovered a solid inner core, with a radius of about 600 km, inside Mars, thereby providing crucial clues to the evolutionary ...

Begin 2026 with intention by shifting from inherited beliefs and automatic reactions to conscious choice and inner authority.

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

She pointed to evidence that the Earth’s inner core was solid — not liquid, as scientists had believed — a discovery that was ahead of its time. Inge Lehmann in 1932. She overcame discrimination in ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from earthquakes travel about 3 to 4 percent faster along the planet’s rotation axis ...

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

For years, the secrets of Earth’s inner core have remained concealed beneath layers of rock and metal, making it one of the most challenging areas of study in planetary science. Despite its ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...

The findings will help guide scientists towards a better understanding of Mars’ evolution as a planet. Credit: JPL-Caltech Seismic studies reveal Mars may have a solid inner core. The result deepens ...

The iron-rich core at the centre 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, ...

Alfred Wilson-Spencer receives funding from the Natural Environment Research Council (NERC) grants NE/T000228/1 and NE/V010867/1. He works for the University of Leeds. The iron-rich core at the centre ...
