Study: Earth's precious metals from spaceBoulder, Colo. (UPI) Dec 9, 2010 Gigantic collisions 4.5 billion years ago injected precious elements such as gold and platinum into on Earth, the moon and Mars, a study suggests. In the final period of planet formation, a body possibly as big as Pluto probably collided with the Earth after the planet had been hit by an even large object, scientists at the Southwest Research Institute in Boulder, Colo., said. Mars and the moon absorbed smaller but still devastating blows, they said. Gold, platinum, palladium and ... read more |
