Astronomer, physicist, and philosopher Galileo Galilei was referred to as "The Father of Modern Science," because of his groundbreaking research.

Join Galileo on his pioneering journey to see why his work had such long-lasting implications, and why the Catholic Church even condemned him for heresy.
