Starting with our solar system, National Geographic explores the true meaning of the words "big" and "small."

But every giant object in our expansive universe is made of tiny bits of matter — the atom – which is a universe within itself on a minute scale. Peer into the atomic world where scientists are using nanotechnology to develop lifesaving cures and ingenious inventions.
