Tiny Specks Reveal Secrets of Asteroids: Scientists Discover Need for Bolder Measures to Prevent Collisions
Scientists have uncovered some of the secrets of asteroids by studying tiny specks of dust from an asteroid called Itokawa. The research, published in the journal Proceedings of the National Academy of Sciences, shows that these space rocks are vastly older than previously thought and much tougher than expected. This new information could mean that we need bolder ways to prevent catastrophic collisions with Earth.
