There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

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 ...

Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

The heart of our planet has been spinning unusually slowly for the past 14 years, new research confirms. And if this mysterious trend continues, it could potentially lengthen Earth's days — though the ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface ...

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth’s crust through its core. The very center of the planet, a solid ball of iron and nickel ...

“It’s probably benign, but we don’t want to have things we don’t understand deep in the Earth.” Now, a recent study published in the scientific journal Nature Geoscience reveals a curious new detail ...
