Angkor Wat, Cambodia, is the world's largest ancient religious temple. Within its megalithic ruins, researches have discovered a depiction of a species of dinosaur--a stegosaurus. But how could the ancients have had knowledge of animals that mainstream science says died out millions of years ago? Why are dinosaurs extinct? Did an alien race of beings kill off the dinosaurs to make room for humankind?

Scott Wolter investigates the mysterious disappearance of vast amounts of copper from Lake Superior. Through scientific testing a connection is made to a pre-historic civilization and the Bronze Age.

Geologist Scott Wolter visits a Minnesota farmer who wants to investigate the possible existence of bones from a giant he unearthed in his yard. The bones raise the question of whether Vikings could have traveled all the way to America.

Might an examination of Leonardo Da Vinci's masterful paintings, highly technical hand-drawn sketches, and private journals reveal knowledge of otherworldly technology and extraterrestrial beings?

Military innovation is consistently at the cutting edge of technological advances. Almost all technology on the planet today owes its origins to inventions driven by one purpose--war. From apocalyptic skyscraper siege machines to ancient landmines and flamethrowers which had the potential to extinguish hundreds of lives in minutes, most of today's lethal weapons owe their origins to the inventors of the ancient world.

In Mexico, explorers use a sacred ancient Mayan temple code to search for an occult underworld engineered in the depths of the earth--a mysterious site where no TV cameras have ever ventured. In Britain, investigators uncover the secret technologies behind a life size statue of Jesus Christ that miraculously came to life. Weapons experts reveal the science that saved a holy military order from certain annihilation in the bloodiest siege in history. In Greece, archaeologists solve the mystery of the oracle of the dead; an eerie sanctuary where flying ghosts appeared from the depths of hell.

There really are ice worlds like Hoth from Star Wars. In this episode, we explore icy planets and moons, discover the role of cold in the Universe, and learn about the importance of ice to the development of habitable worlds.

To know our place in the universe take a look far, far away to the realm of Alien Galaxies. Our galaxy is one of hundreds of billions in the universe. The Milky Way consists of more than a billion stars, our sun being only one of them. Take a view of the universe through the Hubble Space telescope and go back almost all the way to the Big Bang. 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 life forms might evolve in alien atmospheres.

Director and host James Fox assembles the most credible UFO witnesses from around the world to testify on the subject and share their experiences and observations. Air Force generals, astronauts, military and commercial pilots, government and FAA officials from seven countries gather at the National Press Club in Washington D.C. to tell stories that, as former Arizona governor Fife Symington states, "will challenge your reality." These accounts reveal a behind-the-scenes U.S. operation whose policy, in the eyes of some observers, seems to involve confiscation of substantiating evidence from close encounters--to the extent that even Presidents have failed to get straight answers.

The apocalyptic future of our gambling meccas. In Las Vegas, a new rat pack takes over, wax figures of celebrities melt, and iconic hotels crumble. In Atlantic City, the ocean tears apart casinos, but the boardwalk refuses to be destroyed.

January 7, 1610: Galileo, one of history's most brilliant men, trains a new invention on the night sky. His machine is the telescope, and what it reveals will challenge the Church's view of the universe and the very word of God. Galileo is about to unlock the secrets of the heavens, but his work will put him in mortal danger and lead him to a pivotal moment of trial by the Holy Roman Inquisition.
