Could there be plate tectonics on other worlds? One former Idaho scientist thinks it’s possible. Until now, the movement of pieces of a planet’s crust was found nowhere else in the universe except Earth.
It was the late 1990s and University of Idaho planetary geologist Simon Kattenhorn was looking at one of Jupiter's moons named Europa. NASA’s Galileo orbiter took the pictures of it. Using those images, Kattenhorn discovered something remarkable.
