Galileo's Telescope

Galileo Galilei built dozens of telescopes back in the 16th Century when he changed the world and sparked a debate between religion and science that's still raging. Only two of the instruments exist today. One of them is now in Philadelphia, at the Franklin Institute, the centerpiece of an new exhibit: "Galileo, the Medici and the Age of Astronomy." We talk with Derrick Pitts, chief astronomer at the Franklin Institute who's peered down the lens of Galileo's looking glass and got a peak at history
