There are several theories about how the Earth and the Moon were formed, most involving a giant impact. They vary from a model where the impacting object strikes the newly formed Earth a glancing blow ...

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 ...

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.

Old crystals found in Western Australia are drawing fresh attention from geologists studying how the planet first took shape.

Violent collisions between the growing Earth and other objects in the solar system generated significant amounts of iron vapor, according to a new study by LLNL scientist Richard Kraus and colleagues.

Scientists suggest that huge reserves of hydrogen inside the Earth may have been key in the formation of water.

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 ...

Billions of years ago, in the giant disk of dust, gas, and rocky material that orbited our young sun, larger and larger bodies coalesced to eventually give rise to the planets, moons, and asteroids we ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

Earth held a deep ocean of magma beneath its surface in its early history, new research finds, potentially explaining odd anomalies seen in the mantle today. This basal magma ocean has been hotly ...
