Measurements of seismic waves over many years suggest the Earth's core is deformed and reshaped by conditions of extreme heat and pressure.

Most of the time, the shape of Earth’s magnetic field is quite similar to that which would be produced by a bar magnet aligned with the planet’s rotation axis. This is what makes a magnetic compass ...

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

Deep beneath our feet, far below the crust and mantle, Earth is quietly sending out a slow magnetic heartbeat. Every seven ...

"A strong magnetic field is very important for life on a planet." ...

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 ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

Cartoon of the Earth with cutaway showing the mantle and inner and outer core. Magnetic field lines produced by the geodynamo extend into space and interact with the solar wind. The iron-rich core at ...
