The heart of our planet has been spinning unusually slowly for the past 14 years, new research confirms. And if this mysterious trend continues, it could potentially lengthen Earth's days — though the ...

"A strong magnetic field is very important for life on a planet," study lead Miki Nakajima, an associate professor in the ...

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth’s crust through its core. The very center of the planet, a solid ball of iron and nickel ...

A bullet-speed experiment reveals that the Earth's inner core may be softer and more dynamic than previously thought.

How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it — very, very carefully. This is ...

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 inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal Nature ...

(CNN) — Scientists who just months ago confirmed that Earth’s inner core recently reversed its spin have a new revelation about our planet’s deepest secrets — they identified changes to the inner core ...

The Chinese-led research team based its findings on seismic readings from NASA's InSight lander on Mars, which recorded more than 1,300 marsquakes before shutting down in 2022. The spacecraft landed ...

In addition to shaping the interior of rocky planets, molten rock located deep within these planets may also contribute to ...
