NOVA Wonders Are We Alone?
Hunt for clues in the universe to answer one of humanity's biggest questions: Are we alone?
The search for extraterrestrial life is an age-old quest. But recent breakthroughs make today an era like no other in the history of astronomy. From the exhilarating probing of our own solar system and the Kepler mission’s astounding discovery of thousands of extrasolar planets, to the next-generation telescopes under development, the prospects for finding life beyond Earth have never been stronger. Still, daunting hurdles remain. How can we study anything light years away, let alone a little planet? In the vast universe, where should we even start to look? Is our failure to hear any other voices in the galaxy a sign that we are special? NOVA Wonders joins leading explorers now searching the galaxy for life and intelligence on other planets—and asks, if we do find other life in the universe…what would that mean?
