High-voltage proton beam data for stone formed outside solar system

Caption

A high-voltage proton beam shows three trace elements in the extraterrestrial Hypatia stone, and their concentrations. Here, we see sulphur, iron and nickel for targets 1 and 2 within region 14 on the sample. Dr Georgy Belyanin (University of Johannesburg) used a 3-million Volt proton beam to analyse the tiny fragment of the stone.
