Exciting stuff , more discoveries every day





Commenting, Professor Richard Carlson (Carnegie Institute of Washington), Past President of the Geochemical Society said: "This exciting result is adding to the observational evidence that important aspects of Earth's composition were established during the violent birth of the planet and is providing a new look at the physical processes by which this can occur".

According to lead researcher Associate Professor Sujoy Mukhopadhyay (Harvard): "The energy released by the impact between the Earth and Theia would have been huge, certainly enough to melt the whole planet. But we believe that the impact energy was not evenly distributed throughout the ancient Earth. This means that a major part of the impacted hemisphere would probably have been completely vaporised, but the opposite hemisphere would have been partly shielded, and would not have undergone complete melting".
