Lasers melt rocks to reveal development of super-Earths and how giant impacts make magma

Advanced laser shock technique puts magmas under highest-ever pressures New experiments provide insight into how Earth-type planets form when giant asteroids or planetesimals collide and how the interiors of such planets develop. Researchers at Hiroshima University, Osaka University, Ehime University, University of Tokyo, and the Chiba Institute of Technology collaborated to publish their research in… Read more
