A new simulation puts forth a different theory -- the Moon may have formed immediately, in a matter of hours, when material from the Earth and Theia was launched directly into orbit after the impact.

How did Earth, alone among the solar system's rocky planets, become the home for life? How, among all this frigid ...

Scientists have developed supercomputer simulations that may explain how the Moon may have formed after a collision between the Earth and Theia, a Mars-sized planet about 4.5 billion years ago.

Seismic imaging has revealed two colossal regions deep within Earth’s mantle that could reshape our understanding of the ...

How did Earth, alone among the Solar System's rocky planets, become the home for life? How, among all this frigid ...

Conducted by researchers from Durham University's Institute for Computational Cosmology, the simulation suggests Earth’s collision with Theia 4.5 billion years ago may not have been the cause of ...

Researchers ran simulations to track material from the early Earth and Theia for four days after their collision, then ran other simulations after spinning Theia like a pool ball.

Billions of years ago, a version of our Earth that looks very different than the one we live on today was hit by an object about the size of Mars, called Theia – and out of that collision the ...

This new simulation posits that an object the size of Mars may have collided with the Earth of that time, creating what would later become our Moon. The object in question is called Theia. This ...

Bob McDonald's blog: Researchers at NASA and in the UK developed the highest resolution simulation of the collision between a hypothetical rogue planet dubbed Theia and a primitive Earth that is ...

Researchers ran simulations to track material from the early Earth and Theia for four days after their collision, then ran other simulations after spinning Theia like a pool ball.

Most theories claim the Moon formed out of the debris of this collision, coalescing in orbit over months or years. A new simulation puts forth a different theory – the Moon may have formed immediately ...
