The Loch Ness Monster is one of the world's most enduring mysteries. But there have also been accounts of similar cryptids all over the planet. Sightings of these mysterious creatures have been documented for hundreds of years in various cultural folklores. Are these fantastic creatures leftover dinosaurs, mythical animals or something that traveled to Earth millions of years ago? Or might the sightings of these strange beasts be a glimpse into the past caused by a disturbance in the space-time continuum? Ancient Astronaut theorist Giorgio Tsoukalos travels from the Highlands of Scotland to the shores of Vermont's Lake Champlain in his quest to learn more about these elusive lake monsters. Could there be a link between two of the most famous creatures in the world--Nessie and Champ? Is there a correlation between the geology of their locations? And what surprising role might physics play in understanding just what eyewitnesses claim to have seen?

All over the planet, strange events suggest that aliens are among us: A Colorado farmer discovers a cow mysteriously mutilated by unknown forces; a Texas man is repeatedly abducted and claims he is the subject of extra-terrestrial experiments; and, an Ohio astronomer intercepts a mysterious message from outer space.

We are not alone. A mysterious email leads us to what could be a massive underwater UFO base off the Malibu Coast. Could an alien satellite, nicknamed the Black Knight be spying on us from orbit? An investigation of Area Fifty-One takes a dangerous turn...and what is Area Fifty-Two?

A mountain climber goes missing near Mt. Hayes, where UFO sightings are rampant. Our team of investigators head into alien territory and risk close encounters to find answers about his mysterious disappearance. Using eyewitness and expert testimonials, the team searches for evidence of potential extraterrestrial abductions in the Alaska Triangle.

Delve into the myths, misconceptions, truths, and amazing mysteries of our unique universe. Could life exist on Mars? Is time travel possible, and does Einstein's theory of relativity support it?

They've discovered water on other planets, and snatched the actual building blocks of life from a comet's tail. But can space probes find a new Earth...and even make contact with alien life?

Warp speed, transporters, wormholes, and lasers--they are all staples of science fiction books, movies, and TV shows. But the fantastic world of tomorrow is quickly becoming the futuristic world of today.

Take a tour of the cosmic hot zones--black holes, galaxy mergers, gamma ray bursts and magnetars. Super massive black holes can literally "lasso" the Earth out of the solar system. A clash between two galaxies can result in a barbaric ritual called "galactic cannibalism" in which the dominant galaxy's super massive black hole literally eats the weaker one. Magnetars are a cosmic magnetic force so strong it could wipe out data on every credit card on the planet. Cutting-edge computer graphics are used to bring the universe down to earth to show what life would be like on other planets, and to imagine what kind of life forms might evolve in alien atmospheres.
