Treating ancient Earth and Theia as solid geological bodies transforms simulations of the collision that may have created the ...

Although the Earth has long been studied in detail, some fundamental questions still have to be answered. One of them concerns the formation of our planet, about whose beginnings researchers are still ...

New simulations suggest the moon may have formed almost instantly after a giant impact, not slowly from a debris disk.

A peculiar property of the Earth's magnetic field could help us to work out how our planet was created 4.5 billion years ago, according to a new scientific assessment. There are several theories about ...

The findings, published in The Astrophysical Journal Letters, account for the material strength of the two colliding worlds ...

A study on the Earth's formation titled "Stochastic accretion of the Earth" has been published in the journal Nature Astronomy. Researchers from ETH Zurich have used a new modeling approach to ...

Crystals hidden in Australia’s oldest rocks have revealed new clues about how Earth and the Moon formed. The study suggests Earth’s continents didn’t begin growing until hundreds of millions of years ...

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 ...
