Scientists have pinned Earth’s inner core temperature at roughly 5,400 degrees Celsius, a figure that rivals the surface of the Sun. That number rests on high-pressure laboratory experiments that ...

Earth's inner core, composed primarily of iron with a small percentage of light elements, may enter a superionic state at extreme pressure and temperature, according to experimental results from ...

Iron hydride was compressed in a laser-heated diamond-anvil cell and analyzed using synchrotron X-ray diffraction, revealing evidence of a superionic state. Earth's inner core, composed primarily of ...

It was a journey to the center of the Earth, if only for the briefest of moments. But rather than tunneling thousands of miles from Earth's surface, researchers from Lawrence Livermore National ...

What the research is about Earth's inner core is thought to consist mainly of iron, yet many questions remain about its ...

Earth's core: solid or liquid? Yes — we know more about distant galaxies than our own interior. Is Earth's core solid or liquid? Yes. Our planet's interior has been harder to study than the cosmos. We ...
