Summary

Story summary

A study indicates that Earth's life-supporting conditions resulted from a collision with the protoplanet Theia, which provided essential volatile elements.
Initially, Earth was dry and inhospitable, lacking vital compounds for life, suggesting habitable planets may be rarer than previously believed.
Researchers from the University of Bern dated Earth's chemical profile formation to within three million years after the solar system's origin. Further research is required to explore Theia's impact on Earth's habitability.
