For years, scientists have pondered the mysterious structures deep within the Earth. Research indicates that they are ...

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 ...

These structures are theorized to contain remnants of Theia's materials, offering valuable insights into the ancient collision. The presence of large low-velocity provinces in Earth's mantle ...

The Earth and Moon system we see today was formed when Theia, an ancient planet about the size of ... Most theories claim the ...

"Most planetary collision scenarios are classified ... much like how Earth's moon was born after our planet collided with a Mars-sized world dubbed "Theia." In the wake of this colossal impact ...

The prevailing theory was that the Moon was the result of a collision between the early Earth and the protoplanet Theia. New measurements indicate that the Moon formed from material ejected from ...

A recent study by researchers from the University of Göttingen and the Max Planck Institute for Solar System Research has ...
