Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate than a simple metal ball. Instead of a single solid sphere, the inner core ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

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 ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field. The two odd formations – one ...

Scientists have discovered that Earth’s inner core may not be fully solid. (Image: Canva) Earth's inner core may be superionic, behaving as both solid and liquid. Discovery explains slow earthquake ...

New research from Florida State University and Rice University is providing a better estimate of the amount of carbon in the Earth’s outer core, and the work suggests the core could be the planet’s ...

ANU geophysicist Professor Hrvoje Tkalčić says that the dynamics of Earth's magnetic field is an area of strong interest in the scientific community. A doughnut-shaped region thousands of kilometres ...
