How many stars are in the sky? How did the universe begin? Where did it come from? This is the story of Edwin Hubble, a boy fascinated by the stars who surmounted many hurdles to follow his dreams of becoming an astronomer. Using the insights of great mathematicians and endlessly observing the sky, he succeeded in confirming two things that altered human life forever: that there are more galaxies than our own, and that the universe is always expanding. Hubble's message to us is to find peace in the vastness of the mystery surrounding us, and to be curious. "We do now know why we are born into the world," he said, "but we can try to find out what sort of world it is."
