From prehistoric times, to the 21st century, humanity has had a fascination with the stars overhead. Ever-changing and yet perfectly constant, the secrets of the constellations remained locked away in their icy vastness for countless centuries. The sun and stars seemed to rotate around our planet and we thought Earth was the center of the universe, even as we longed to travel among the stars. Beginning with Galileo's use of the early telescope, man began to look deeper into the heavens, discovering our place in the solar system, our Galaxy, and the infinite Universe beyond. By the late 20th century, man had taken his first tentative steps into the future, walking on the moon and sending probes into the depths of space. Science and technology now allow astronomers to look even deeper into space and back in time to the very origins of our universe, and as some mysteries are solved, more appear. This special 2 DVD set, featuring distinguished scientists and guest narrators, takes you on a journey into these mysteries. Along with stunning color photography of deep space, far away galaxies and supernovas, you will confront the most perplexing and fascinating questions of all time.
