The liquid iron in Earth's outer core doesn't always behave as expected. When it changed direction in an unexplained way, ESA ...

Scientists are working to solve a mystery of Earth’s molten outer core, which lies more than 2,000 kilometers beneath our ...

Deep beneath the Pacific near the equator, Earth’s outer core now flows east instead of west. Dynamics deeper within our planet’s core may help explain the change and what to expect in the near future ...

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

Discover how recent changes in Earth's outer core influence its magnetic field and reveal new geological patterns.

The Global Positioning System works because satellites carry atomic clocks. Those satellites orbit high above Earth, where ...

New research suggests giant structures beneath Earth's mantle significantly influence the planet's magnetic field over long ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of these ...

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 ...

Instead of the atoms or molecules of an ordinary liquid, it consists of electrons and ‘holes,’ or the positively charged ...

When you look up at the sky on a sunny day, the sun might seem like a bright spot, unchanging in the sky. But the sun is a ...

NASA's Fermi Gamma-ray spacecraft has observed a super-bright, supercharged supernova explosion powered up by the creation of ...
