New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions about its solidity.

Recent research has revealed that Earth’s core is undergoing a slowdown in its rotation, a phenomenon that has piqued the interest of scientists around the world. Understanding the causes and ...

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 ...

A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could be more viscous ...

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years. These ...

Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the ...

What is the speed and timing of the Earth’s inner core cooling? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated the composition ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...
