Galileo’s Journal: 1609-1610

On his summer vacation, Galileo hears about a remarkable new invention: a tube that makes far-off things look like they are right in front of you. Driven by curiosity, he doesn't rest until he builds his own telescope. He uses it to spot rabbits in his garden and ships far off at sea.Then Galileo points his telescope at the night sky. He sees things that no one has ever seen before --from unknown stars to mountains on the moon. And one night, he makes a discovery that will change the world forever.
