Life on Earth may exist thanks to an incredible stroke of luck — a chemical sweet spot that most planets miss during their formation but ours managed to hit.

Earth's core contains nine to 45 times more hydrogen than the planet's oceans do, according to a new study that could settle a debate about when and how hydrogen was delivered to Earth.

Parts of ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought.

An experiment to quantify the amount of the universe’s lightest element in Earth’s core suggests that the planet’s water has mostly been here since the beginning ...

Amino acids from asteroid Bennu suggest that some of life’s building blocks formed in icy conditions in the early solar system.

Earth’s habitability may trace back to a precise chemical balance during its formation, one that kept life-critical elements from disappearing into the core or drifting into space.

A study published in the journal Earth and Planetary Science Letters posits that Mars formed in what today is the Asteroid Belt, roughly one and a half times as far from the sun as its current ...

Researchers investigate the effects of oxygen content on the melting of mantle rocks and the formation of early Earth magma It is widely accepted that the early Earth largely consisted of molten magma ...

Scientists have identified what could be the oldest rocks on Earth from a rock formation in Canada. The Nuvvuagittuq Greenstone Belt has long been known for its ancient rocks — plains of streaked gray ...

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that ...
