Are We Alone? (EP3)
Résumé de l'épisode 3
We live in a galaxy with over 200 billion star systems, many of which will be home to planets which could support life. The question is: is there anybody there? After all, if the universe has thrown up one intelligent civilization - us - why not more? Brian Cox investigates our human urge to contact alien intelligence, visiting the deserts of Northern California to join the hunt using the world's most sensitive alien hunting radio telescope.
