400 Years of the Telescope

In the 400 years since Galileo turned his spyglass to the skies and discovered that Jupiter has four moons, and since that time telescopes have provided us a better understanding of space and how it works. In those days, many thought that Earth was the center of the universe. But we've come a long was since the 17th Century, and in this documentary, filmmakers explore the history of the telescope from the time of Copernicus to the development of the Hubble telescope.
