Where does the metal in meteors come from?
Outer space is far from empty. There are chunks of space rock zipping around, and occasionally one of them finds its way through our atmosphere to smack into Earth’s surface. There’s usually metal contained within those space rocks…but where does the metal come from? We asked planetary geologist Paul Byrne to help us find the answer.Got a question that’s totally metal? Send it to us at BrainsOn.org/contact, and we’ll STARt looking for an answer!
