Host and Executive Producer William Shatner explores our earth-and beyond-in search of the universe's most fascinating, strange and inexplicable mysteries.
Unidentified objects, witnessed by military pilots... Extraterrestrial probes, flying through our solar system... And a potential alien home world that may be hidden--in the darkness of space.
As we make plans to travel beyond the Moon to new worlds, how are we preparing to become human extraterrestrials? Just how will we survive this trip into the unknown?
This glowing yellow orb that's about the same size as our world is covered in massive volcanoes, poisonous clouds of acid rain, and a surface temperature hot enough to melt lead. Is Venus our evil twin--or a warning about the future of Earth?
From massive asteroids and deadly bursts of radiation to microscopic alien viruses, each one of these cosmic dangers may end human civilization as we know it. Can we prepare for the inevitable calamity that may be coming our way?
We humans want to boldly go into uncharted territories to make new discoveries. As the next era of space exploration begins, what will we find when we reach other planets? What dangers will we face when we try to conquer these new frontiers?
Earth's moon is only one of hundreds in the solar system--each of them a mysterious and often bizarre world. Could alien moons offer a key to exploring outer space and perhaps even finding a new home for humanity?
Humanity has worshipped the Sun since the beginning of time, and yet even with our modern technology, we still know so little about it. Could unlocking the mysteries of the Sun be the difference between life and death for human civilization?
