Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner ...

A new analysis of meteorite isotopes challenges long-held ideas about Earth’s origins, suggesting our planet may have formed ...

Planetary scientists led by Paolo Sossi have determined that Earth assembled almost entirely from material originating in the ...

For years, planetary scientists have argued that some of the material that built Earth must have drifted in from beyond ...

The chemical composition of meteorites and asteroids acts as a kind of fingerprint, providing information about the origin of ...

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. A new study shows that Earth formed under ...

Earth may have won a cosmic chemistry lottery. Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements, ...

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

Over 4.6 billion years ago, Earth took shape from a spinning cloud of dust and gas surrounding the young sun. Tiny particles within this cloud collided and clumped together, driven by gravity and ...

Earth likely formed from inner Solar System material alone, raising fresh questions about the origin of water on our planet.

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 volatile ...
