Voyager - Ai confini della conoscenza (DVD Collection) is a DVD series by the Italian publishing house De Agostini distributed in newsstands in 2007. It re-proposes in 50 issues the best of the Rai2 program of the same name and in some issues material never treated on TV. The series is part of the merchandising linked to the Voyager program which between 2003 and 2018 achieved considerable public success allowing the flourishing of books, magazines and, precisely, this series of DVDs linked to the theme of alleged unsolved mysteries (mysterious archaeology, ufology, paranormal, and pseudosciences in general).
