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

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

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

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

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

How did the Moon form and how fast did it happen? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of | Space ...

A new scientific study is challenging ideas about how quickly the Moon formed, with researchers suggesting it may have taken ...

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.

Many of the most interesting bodies in our Solar System aren’t planets, but the moons that orbit them. They have active volcanoes, hydrocarbon oceans, geysers, and moon-wide oceans buried under icy ...

It seems a large companion is difficult for a planet that size and distance from the Sun to hold on to, which might be bad ...
