"Scientists say Earth and Mars are different to the core<br />SCIENCE AND TECHNOLOGY FACILITIES COUNCIL NEWS RELEASE<br />Posted: June 28, 2007<br /><br />Research comparing silicon samples from Earth, meteorites and planetary materials, published in Nature (28th June 2007), provides new evidence that the Earth's core formed under very different conditions from those that existed on Mars. It also shows that the Earth and the Moon have the same silicon isotopic composition supporting the theory that atoms from the two mixed in the early stages of their development. <br /><br />This latest research which was carried out by scientists from Oxford University along with colleagues from University of California, Los Angeles (UCLA) and the Swiss Federal Institute of Technology in Zurich (ETH) compared silicon isotopes from rocks on Earth with samples from meteorites and other solar system materials. This is the first time that isotopes have been used in this way and it has opened up a new line of scientific investigation into how the Earth's core formed.
