This edition: The Search for Life Beyond Earth
Are we alone? This question has driven individuals to look up at the starry sky and ponder this question since the beginning of human existence. As a first step toward answering this question in our search for life amongst the stars and distant planets, we are required to define what life is. In this video, leading astronomers from the SETI Institute and other planetary scientists reveal how current research may (or may not) uncover life beyond Earth within the next few decades. Each result will affect how we look at ourselves and our place in the cosmos.
