By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Deep inside Earth, researchers see signs that the solid inner core may be arranged in multiple chemical layers far below.

Researchers have found evidence that Earth's core is leaking gold and other precious metals, according to a new study. The vast majority (99.9%) of Earth's gold and other precious metals are hidden in ...

Earth's day-night cycle is defined precisely, each a span of 24 hours before the next begins. Such is the yardstick by which we live our lives, strictly adhering to the ticking of the clock. Earth, ...

Deep under the crust and mantle of our Earth lies its core. Earth’s core was formed during the Iron Catastrophe, a major ...

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

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 ...

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 ...

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 ...

With modern seismic tomography, Earth scientists have discovered that above Earth's core-mantle boundary (CMB), about 2,900 ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...
