The ancient history of Earth has always been hard to read. Most of the planet’s earliest crust has been lost, buried, or melted by geologic processes over billions of years.

However, light that leaves our star also contains UVC radiation, which has a shorter wavelength than UVA or UVB light and ...

Thick clay deposits on Mars hint at long-lived lakes that may have sheltered early life - and preserved clues beneath layers ...

A recently published study has revealed a little-known tectonic process unfolding beneath Turkey’s Central Anatolian Plateau, where part of the Earth’s crust is “dripping” deep into the planet’s ...

Let's say we want to build a model of the sun and Earth alone. Earth has a radius of about 6,371 kilometers (3,959 miles), but let's represent this with a marble 1 centimeter in diameter.

The Earth is made up of a total of 7 layers which are- crust, lithosphere (crust and uppermost mantle), asthenosphere (upper mantle directly below the lithosphere), lower mantle, outer core and ...

The solid metal core of Earth does not rotate perfectly in time with the outer layers of the planet, and new research ...

This layer, known as the D" layer, is about 1,900 miles underneath the Earth's surface, resting between the liquid outer core and the solid mantle, and varies massively in thickness across the globe.

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 ...
