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 ...

Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many ...

Intriguingly, the inner core's rotation affects life on the surface, according to researchers involved in the study. "It has effects on the magnetic field and the Earth's rotation, and perhaps the ...

The new research from the University of Southern California, now published in Nature, noticed that the Earth’s inner core was moving slower than the surface, termed “backtracking,” and has ...

The structure of Earth's core could be unlike any other state of matter, researchers have found. Yu He, a physicist at the Chinese Academy of Sciences and lead author of a study published this ...

The latest discoveries about the inner core have fueled vigorous disagreements among the world's top Earth scientists and given rise to competing theories of varying credibility, Vidale says. Some ...

More than 5,000 kilometers beneath us, Earth's solid metal inner core wasn't discovered until 1936. Almost a century later, we're still struggling to answer basic questions about when and how it first ...

The Earth’s inner core is separated from the rest of the solid Earth by its liquid outer core, so it rotates at a different pace and direction than the planet itself.

Even more intriguing, though, is that this new study claims that the Earth’s inner core has halted its spin relative to the mantle. To discover this, the researchers look at earthquakes between ...

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 ...

The inner Earth is a mysterious place, and now scientists may have uncovered a strange new secret. According to a new study, the Earth’s inner core may have recently stopped rotating, relative ...
