      • UFO Hunters II (5)

        The Real Roswell. The story of a spacecraft crashing in Roswell, New Mexico, is the most famous case in UFO history. Now, a theory has emerged that there was more than one crash site.

      • Ancient Aliens IX (11)

        Space Station Moon. What if the Moon is not the natural object we believe it to be? Unidentified lunar objects in NASA photography may point to extra-terrestrial structures on the moon, and possibly evidence of what lies beneath the surface.

      • Project Impossible (9)

        Conquering The Arctic. Above the arctic circle, projects are underway that are opening up the Arctic to the rest of the world. On this episode: building a nuclear-powered icebreaker in Russia; and constructing a modern airport on Baffin Island.

      • Evolve (5)

        Communication. A look at communication as a key tool for survival, from simple bacteria cooperating to take down creatures a million times their size, to mankind's complex systems of interacting.

      • Evolve (6)

        Flight. How did flying creatures come to be? From the first vertebrates to take flight to the creatures that have conquered the sky, examine the animals which have evolved to fly.

      • The Universe II (17)

        Gravity. Gravity is the most powerful and exacting force in the universe. It is pervasive and penetrating. Gravity binds us together, its reach hangs stars in the sky and its grip crushes light.

      • Doomsday: 10 Ways The World Will End (2)

        Black Hole. Human civilisation is under attack from a catastrophic - but unseen - threat from space. As a supermassive black hole approaches our planet, its enormous gravitational forces trigger earthquakes, volcanic eruptions and tsunamis of unprecedented size.

      • Brad Meltzer's Decoded II (11)

        Houdini: Murdered? Most contend the world's most famous magician died when one of his tricks went fatally wrong, but new evidence suggests that his death may have been no accident.

      • The Universe II (18)

        Cosmic Apocalypse. The Universe as we know it is condemned to death. Space, matter and even time will one day cease to exist and there's nothing we can do about it. Harsh realities are revealed about the future of our Universe.

      • Doomsday: 10 Ways The World Will End (3)

        Rogue Planet. What might happen if a ringed planet the size of Neptune were on a collision course with Earth? Total destruction in just four hours.

      • Brad Meltzer's Decoded II (12)

        Devils Graveyard, Alaska. The Alaska Triangle--the region between Anchorage, Juneau and Barrows--has a disappearance rate sixteen times the national average, and scientists are entirely incapable of explaining why.

      • UFO Hunters II (6)

        Arizona Lights. On March 13, 1997, a string of fiery globes were seen over Arizona, but earlier that night some eyewitnesses saw something even more shocking - a huge boomerang-shaped object.

      • Ancient Aliens IX (12)

        Russia's Secret Files. Russia is the home of 'cosmism', a belief that human civilisation originated in the cosmos and is destined to return to space. But many believe the rise of communism led to a wall of secrecy surrounding extraterrestrial contact in Russia.

      • U-Boat Wargamers (6)

        The End Game. WATU faces a crucial encounter for ONS.5 in the Battle of the Atlantic. Dönitz unleashes the new torpedo that targets the escort ships. Roberts and Laidlaw must counteract the new weapon and recapture the waves.

      • Lost Worlds II (8)

        Sin City Of The West. The Wild West was full of gambling, frenzied gold rushes and legendary racketeers. It was a lawless age when people wanted two things: money and a good time.

      • Doomsday: 10 Ways The World Will End (9)

        Alien Invasion. When rogue aliens launch a surprise attack on Earth, people are left dying in the streets, world governments are obliterated, cities are destroyed and a deadly virus is unleashed. Can mankind survive, or is this the end?
