Four hundred and sixty-six million years ago, there was a giant collision in outer space. Something hit an asteroid and broke it apart, sending chunks of rock falling to Earth as meteorites since before the time of the dinosaurs. But what kinds of meteorites were making their way to Earth before that collision? In a new study in Nature Astronomy, scientists have tackled that question by creating the first reconstruction of the distribution of meteorite types before the collision. They discovered...
