Soon after the Earth coalesced in the early solar system, it was hit by another ... suggesting that instead of bouncing off each other like pool balls, Theia and Earth got mixed together like ...

A new study suggests that portions of the moon-forming impactor Theia survived throughout Earth's history deep in our planet's mantle. Some 4.5 billion years ago, the solar system was a giant game ...

The prevailing theory of the moon’s formation is called the giant impact hypothesis, in which a Mars-sized object called Theia slammed into Earth and was blown to bits, creating the moon from ...

We found big chunks of the impactor Theia.” With those five words to The New York Times, Caltech geophysicist Qian Yuan ...

Long ago, our solar system lost a planet. The planet, which scientists have since named Theia, found itself barreling uncontrollably toward a young Earth. The resulting impact destroyed Theia ...

Try this experiment — all you need is a ball, pen, candle ... That rock has a name: Theia. This requires an explanation. You probably know about the asteroid that smashed into Earth about 66 million ...

A big piece of early Earth ... named Theia slammed into Earth, scattering debris that congealed into the moon. Models suggested that the collision totally melted our planet, creating a ball ...

The most prevalent and accepted idea has been a collision between Earth ... Theia) colliding. As the simulation ran, the ultimate "victors" were three or four terrestrial worlds in the inner-solar ...

The simulated collision with the early Earth produced different results depending upon the size and direction of Theia’s initial spin, from no spin at all to 'spinning like a pool ball', both ...

Along the way, they worked out that the Earth-Theia impact must've occurred around 4.47 billion years ago, or about 95 million years after the Solar System came into existence. [Research paper ...
