Galileo's Battle for the Heavens

In this two-hour special, NOVA celebrates the story of the father of modern science and his struggle to get Church authorities to accept the truth of his astonishing discoveries. The program is based on Dava Sobel's bestselling book, Galileo's Daughter, which reveals a new side to the famously stubborn scientist—that his closest confidante was his illegitimate daughter, Sister Maria Celeste, a cloistered nun.
