William Shatner explores our earth, and beyond, in search of the universe’s most fascinating, strange and inexplicable mysteries. Each episode features contributions from scientists, historians, astronauts and other experts—each seeking to shed light on how the seemingly impossible actually can happen. Seeking answers to age-old questions that have mystified mankind for centuries. Things like, how was our earth born? Will we go back to the moon—or venture even farther? What dangers might lurk in the deep expanse of outer space? And perhaps the biggest of all—are we alone?
