No one knows why the river of liquid iron flowing 1,400 miles beneath our feet just reversed course.

Scientists discovered a mysterious reversal in Earth’s molten core flow beneath the Pacific using satellite data from space.

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, ...

ESA satellites detected a dramatic reversal in Earth’s molten core flow beneath the Pacific, revealing unexpected changes ...

Deep beneath our feet, approximately 2,890 kilometers underground, lies one of Earth's most mysterious regions. The boundary between our planet's molten outer core and solid mantle acts like a massive ...

PCWorld reports that scientists discovered Earth’s inner core has slowed its rotation relative to the crust, even appearing to stop moving in a phenomenon that occurs every 35 years. This iron-nickel ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's ...

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, ...

LONDON — Picture all of Earth's oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth's core, possibly ...
