Far below the deepest boreholes, Earth’s core appears to keep its own rhythm, a slow magnetic throb that repeats roughly ...

Deep beneath the familiar blue of the oceans, Earth may be hiding a far larger sea of potential. New high pressure experiments suggest the planet’s metallic heart could store hydrogen equivalent to ...

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion ...

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 ...
