A study published in Science Advances demonstrates, through experiments conducted at very high pressure and high temperature at the Institute of Earth Physics of Paris (IPGP), that ...

A rocky planet beyond gas dwarfs in LHS 1903 indicates that planetary systems form in unexpected ways.

Plate subduction traverses multiple Earth spheres, transporting surface and lithospheric materials to the deep interior and reaching the core-mantle boundary (CMB). Conversely, mantle plumes convey ...

Understanding where Earth’s essential elements came from—and why some are missing—has long puzzled scientists. Now, a new study reveals a surprising twist in the story of our planet’s formation.

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics. Researchers have made a new discovery that changes ...

(CNN) — Researchers say they have uncovered evidence that early Earth was home to more hydrogen than previously thought, calling into question widely held beliefs about the origins of water and the ...

Earliest inner solar system planetesimals shaped the inventory of moderately volatile elements in terrestrial planets. Understanding where Earth's essential elements came from -- and why some are ...
