The giant-impact hypothesis posits that billions of years ago a Mars-sized body named Theia collided with the early Earth. The immense energy from this impact not only significantly altered Earth ...

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 simulations corroborate the hypothesis that materials from Theia were introduced into Earth's lower mantle during the impact event. Ongoing debates persist among scientists regarding the ...

Other scientists propose that after the impact all of the oxygen was able to move around in the hot vapor surrounding the Earth and moon, mixing up all the different oxygen isotopes and erasing any ...

Caption MFM simulation of the canonical Moon-Forming giant impact. Here different colors trace different components of Gaia and Theia. The lower mantle of Gaia, denoted by the dashed circle with a ...

Before Earth and the Moon, there were proto-Earth and Theia (a roughly Mars-sized planet). The giant-impact model suggests that at some point in Earth's very early history, these two bodies collided.

EclipseSource introduces Theia Coder, an AI coding assistant in the Theia IDE. Developers can generate and customize code using natural language. According to EclipseSource, Theia Coder gives ...
