From these indirect observations, scientists have calculated that the scorchingly hot inner core, with temperatures ...

A new analysis of marsquakes measured by NASA’s InSight lander indicates Mars has a solid inner core – but other researchers ...

A new chapter of the Earth's history may be about to be written after boffins discovered evidence there may be another layer ...

The Earth's inner core was once liquid, but has turned solid over time. As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it ...

WASHINGTON, D.C. — Earth’s inner core, a solid metal ball gyrating within the molten outer core, may be both slowing down and changing shape. Recent analyses of earthquake waves have suggested ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about ...

Opinions expressed by Forbes Contributors are their own. Jamie Carter is an award-winning reporter who covers the night sky. A single rotation of our planet takes 24 hours and constitutes a day.

The Earth has a shell-like structure. It is divided into a core (inner and outer core), a mantle (lower and upper mantle, separated by a transition zone), and the earth's crust. The Earth’s ...

Volcanic eruptions long ago brought the 2,492-carat diamond—the latest in a string of stunning discoveries over the last decade—to the surface Rudy Molinek The record-setting rock samples will ...

Electrically charged, liquid iron flows around the solid inner core driven by Earth's rotation and convection currents.

Earth’s inner core, a solid metal ball gyrating within the molten outer core, may be both slowing down and changing shape. Recent analyses of earthquake waves have suggested that around 15 years ago, ...

Geophysicists studying seismic waves from earthquakes have found evidence suggesting that Earth's inner core not only rotates differently but also changes shape. Analysis of earthquake waveforms ...
