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

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

A diagram of Earth's interior with water leaking toward the core Scientists may have finally found the cause of a mysterious, crystal-forming layer that surrounds Earth's core — "leaking water" that ...

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 ...

Scientists believe that Earth's core is a massive ball of iron. However, a new discovery suggests that the Earth's core is surrounded by an unexpected ancient structure. A high-resolution map of the ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field. The two odd formations – one ...

Earth's core isn't exactly aligned with its mantle, which results in a cyclical wobble, new research finds. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

French novelist Jules Verne delighted 19th-century readers with the tantalizing notion that a journey to the center of the Earth was actually plausible. Since then, scientists have long acknowledged ...

Helium-3, a rare isotope of helium gas, is leaking out of Earth’s core, a new study reports. Because almost all helium-3 is from the Big Bang, the gas leak adds evidence that Earth formed inside a ...
