A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new ...

Early Earth lacked life’s essentials until a collision with Theia added them. This chance event made life possible. After the Solar System formed, it took no more than three million years for the ...

Analysis by researchers at the University of Bern suggests that water and other volatile compounds arrived on Earth from ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.

A high-precision time measurement system based on the radioactive decay of manganese-53 was used to determine the precise age. This isotope was present in the early Solar System and decayed to ...

Continental clues: 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 ...

Researchers used atomic-scale computer simulations to discover the importance of carbon in forming a solid planetary core.

Late-stage planetary collisions reshaped Earth and its neighboring planets, delivering water, altering their atmospheres, and ...

A small asteroid has been quietly following Earth’s orbit for decades—unseen, unbothered and, until recently, completely ...
