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

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

Scientists have discovered that the Moon-forming collision may have depended heavily on how hot and physically strong early ...

The research could also influence the hunt for exomoons, which orbit planets outside our solar system.

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

One day in history about 4.5 billion years ago was a dramatic one for Earth, potentially giving our planet an instant moon and an almighty headache all in one go.

The moon could have formed within just five hours of a colossal collision that rocked the early Solar System 4.5 billion ...

The Moon is believed to have formed when a hypothetical object called Theia slammed into the primordial Earth. Theia is ...

How did the Moon form and how fast did it happen? This is what a recent study published in The Astrophysical Journal Letters ...

How did Earth get its Moon? New simulations suggest a Mars-sized body called Theia collided with Earth 4.5 billion years ago, and the Moon could have formed within hours.

Scientists in a recent breakthrough have discovered new clues regarding the formation of the moon, thereby challenging ...

For 50 years, models of the Moon's origin assumed it assembled slowly from a debris disk. Simulations that correct a key ...
