Where does gold come from?

Did you know that gold is extraterrestrial? Instead of arising from our planet’s rocky crust, it was actually cooked up in space and is present on Earth because of cataclysmic stellar explosions called supernovae. CERN Scientist David Lunney outlines the incredible journey of gold from space to Earth.

David Lunney is the Director of Research at France’s CNRS and Head of the nuclear physics group at the CSNSM, Université de Paris-Sud. After slinging protons through the McGill University cyclotron for his PhD, he now hangs around CERN’s radioactive beam facility ISOLDE, transmuting lead atoms into gold. Always ready to discuss physics topics – especially over a beer – David believes that nuclear physicists have much to offer society and are not nearly as dangerous as most people think.
