Where did the universe come from? Where is it headed? And does it harbor intelligent life elsewhere? Today, sophisticated technology is bringing scientists closer and closer to answering those big questions. Join veteran science educator Adam Hart-Davis and his colleagues as they meet investigators probing the very nature of the cosmos--at the edges of space, as well as right here on Earth. Go far beneath Geneva as a supercollider attempts to unlock the secrets of the Big Bang. Follow humankind's deepest space probe as it travels beyond our solar system. And see the spectacular, often violent events revealed by new-generation telescopes and sensors. This eye-opening, six-part series shows how scientists are using ingenious tools to achieve breakthroughs in understanding the stars, planets, and our place among them.
