Extra-terrestrial Intelligences Publication date : October 1, 1992

With J. Heidmann, chief astronomer at the Paris Observatory and head of the MegaSETI project (the search for artificial extragalactic signals), we explore the ultimate frontier of the cosmos. Far removed from parascientific aspects, the autor explains bioastronomy, the search for life in the universe. This fantastic voyage concludes with a down-to-earth debate. What will happen the day a message from elsewhere is heard on Earth?
