About this title
It's one of the great mysteries of life - and perhaps the most intriguing question humans have: Are we alone? Or do we have unknown relatives on distant planets? And if yes - where are they? A group of scientists tries to find answers to these questions - SETI, the Search for Extraterrestrial Intelligence.
