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

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

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

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, ...

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 ...

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

Scientists have long been probing the universe to determine how elements came together to form planets and (at least in Earth’s case) gave rise to life. One disconnect was that the universe contained ...

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 ...
