Scientists have identified two massive thermochemical formations at Earth's core-mantle boundary that refine understanding of ...

Earth is the only known planet to host life, a fact that has long intrigued scientists. While Venus and Mars present extreme ...

Deep below Earth's surface lie two gigantic structures with mysterious origins. Now, seismologists have found new clues about their composition that could upend our understanding of the whole planet's ...

Fresh evidence suggests early Earth wasn’t locked under a rigid stagnant lid but was already experiencing intense subduction.

Southwest Research Institute’s Dr. Simone Marchi collaborated on a new study finding the first geophysically plausible scenario to explain the abundance of certain precious metals — including gold and ...

An interdisciplinary international research team has recently discovered that a massive anomaly deep within the Earth’s interior may be a remnant of the collision about 4.5 billion years ago that ...

The evolution of our Earth is the story of its cooling: 4.5 billion years ago, extreme temperatures prevailed on the surface of the young Earth, and it was covered by a deep ocean of magma. Over ...

This schematic illustrates the most geophysically plausible explanation for the abundance of HSE metals present in the Earth’s mantle. During the long period of bombardment, impactors would strike the ...
