"a combination of two base metals, nickel and iron, which were cooled over millions of years as meteoroids and asteroids tumbled through space. That process created a unique compound with a particular set of characteristics that make it ideal for use in the high-end permanent magnets that are an essential component of a vast range of advanced machines, from electric vehicles to space shuttle turbines... scientists have found a way to make it in a lab"
