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

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

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

A groundbreaking study published in Nature Communications offers new insights into Earth’s inner core, potentially solving ...

Chinese researchers have discovered that interstitial carbon in iron-carbon alloys behaves in a superionic, liquid-like state ...

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 ...

Researchers have uncovered a previously unknown "supersonic state" lurking deep within our planet. Scientists at China's ...

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, ...

A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new constraint on the chemistry of Earth's core, by showing how it was able 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 ...

But despite its importance, many of the most fundamental properties of the core are unknown. We do not know exactly how hot the core is, what it is made of or when it began to freeze. Fortunately, a ...

In 2025, NASA faced unprecedented uncertainty as it grappled with sweeping layoffs, looming budget cuts, and leadership ...
