Scientists at Tokyo Institute of Technology have demonstrated that the relatively high levels of precious metals (gold, platinum, etc.) in the Earth's mantle likely originated from one large-scale planetary impact prior to the formation of the Earth's crust. This implies that the early Earth was a more benign place than previously thought, with fewer impacts from space. The findings are published in Earth and Planetary Science Letters, 4 October 2016.
