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

A groundbreaking study published in Nature Communications offers new insights into Earth’s inner core, potentially solving ...

Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid ...

Around 3,000 kilometers (1,864 miles) beneath our feet, there's a mysterious band of material called the D" layer, which has long fascinated scientists for its lumpiness. Thin in patches and thick ...

Oxygen began entering Earth's oceans around 2.32 billion years ago, and shallow seas followed within a few million years.

There's a lot more to Earth than meets the eye. Far from being just a roundish rock barreling through space, our planet is composed of several layers held together by intense forces of gravity. Our ...

At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth fans). Scientists infer features of this innermost geographic layer—like the ...

A new study confirms that Earth's inner core has been rotating more slowly than usual since 2010. This mysterious "backtracking" could also end up slightly altering the planet's overall rotation, ...

The Earth with the upper mantle revealed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock in a key region just below the tectonic ...

Far out in the North Atlantic, Bermuda sits atop a broad rise in the seafloor that has troubled Earth scientists for decades.
