A detailed simulation of Theia crashing into Earth. While the collision was violent, it was not energetic enough to melt the Earth's lower mantle -- meaning that remnants of Theia could be ...

In this image, the proposed hit-and-run collision is simulated in 3D, shown about an hour after impact. A cut-away view shows the iron cores. Theia (or most of it) barely escapes, so a follow-on ...

"Most planetary collision scenarios are classified as ... Pictured: the researchers' simulation, showing Pluto and Charon (center frame) separating mere hours after their "kiss"-like collision.

This discovery highlights the profound impact of the Moon-forming collision on Earth's structure and composition. Using computational fluid dynamics and a novel simulation method called Meshless ...
