Earth's moon formed inside a cloud of molten rock, and may have done so before our planet itself formed, a new theory suggests. Scientists call such a cloud a synestia, a doughnut-shaped ring of ...

Cosmic dust found in meteorites that crashed on Earth has revealed the shocking detail that the planet formed within 5 million years, significantly faster than first believed.

Anke Wohlers and Bernard Wood use high-pressure experiments to show that the addition of a reduced Mercury-like body to the early Earth, rich in sulfur, could have generated both the ...

In a new study released in Nature this week, researchers say Earth formed within just 3 million years. That’s notably faster than previous estimates that place the timeline as high as 100 ...

The Earth formed relatively quickly from the cloud of dust and gas around the sun, trapping water and gases in the planet’s mantle, according to research published Dec. 5 in the journal Nature. Apart ...

Earth probably formed in a hotter, drier part of the solar system than previously thought, which could explain our planet's puzzling shortage of water. Skip to main content.

The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing ...

How can the metal content of stars influence the formation of Earth-like exoplanets? This is what a recent study published in The Astronomical Journal hopes to address as an international team of ...

A rare form of helium may have flooded Earth’s core during the planet’s formation in the hot, early stage of our solar system, according to a study published this week.

This graphic illustrates how the moon may have formed after multiple collisions on Earth. Moon- to Mars-sized impactors strike the Earth and leave a disk of debris orbiting the planet.

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.
