To find out, the team used whole-Earth oscillation data from 104 past earthquakes to create a detailed 3D model of the upper ...

This sample, which is more than six times longer than the previous core of mantle rock, has given us a glimpse into the composition of this mostly inaccessible layer of the Earth. You can read ...

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

"The composition of mantle domains reflects not only surface processes but also activity deep within Earth," Doucet noted. Understanding these dynamics can help geoscientists identify regions ...

Over 25 years ago, researchers discovered that some of these deep Earth reverberations pointed to the existence of two ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds.

According to scientists from the California Institute of Technology and Swiss research university ETH Zurich, a new method for analyzing the Earth’s mantle — the layer below the crust and abov ...

A team of geophysicists created a detailed model of Earth's lower mantle using earthquake waves. This indicates the presence of zones of rocks that are colder, or have a different composition ...

An exoplanet about 800 light-years away is spilling its guts into space, and new observations with the James Webb Space Telescope, or JWST, have let astronomers read the entrails, astronomers report ...

The mantle, a zone between our planet’s thin ... a professor of structure and composition of Earth’s deep interior at Utrecht University. “There was no information about that,” Deuss ...

Continent-size islands deep inside Earth's mantle could be more than a billion ... Another feature, such as a change in composition, must be responsible for the unexpected result, the team suspected.
