- Arctic Ghost Ship
E2Arctic Ghost ShipNOVA presents an exclusive breakthrough in the greatest unsolved mystery in Arctic exploration. In 1845, British explorer Sir John Franklin set off to chart the elusive Northwest Passage, commanding 128 men in two robust and well-stocked Royal Navy ships, the Erebus and Terror. They were never heard from again. - Krigen i cyberspace
E4Krigen i cyberspaceKrigen i cyberspace bliver varmere og varmere og er ikke længere begrænset til den virtuelle verden. Takket være Edward Snowdons afsløringer kender vi nogenlunde omfanget af den amerikanske sikkerhedstjeneste, NSA's, overvågning af hele verdens elektroniske kommunikation, men ud over det forsøger NSA også at få overtaget på en ny slagmark, cyberspace. Er et nyt våbenkapløb i gang? - Animal Mummies
E5Animal MummiesNOVA joins a team of leading Egyptologists who deploy the latest medical imaging to peer beneath the wrappings of Egyptian mummified beasts without damaging the animal bodies inside. The results are enlightening, often surprising insights into the weird beliefs and practices that clung to the Egyptian quest for immortality. - Making North America: Origins
E6Making North America: OriginsThe epic 3 billion-year story of how our continent came to be. From the palm trees that once flourished in Alaska to titanic eruptions that nearly tore the Midwest in two, discover how forces of almost unimaginable power gave birth to North America. - Making North America: Life
E7Making North America: LifeHow did life emerge on our primeval continent? Why was North America home to so many iconic dinosaurs like T. rex? And how did a huge sea filled with giant marine reptiles end up covering Kansas? We tell the surprising intertwined story of life and the landscape in North America. - Making North America: Human
E8Making North America: HumanThe history of North America since the arrival of humans is chronicled. Natural resources, including gold and oil, have enabled humans to transform the land almost as much as the geological forces that created it. However, geology may, some day, play another role in reshaping the continent: the Cascadia fault line in the Pacific Northwest could unleash a massive earthquake and tsunami; and the super-volcano beneath Yellowstone could obliterate half the continent if it erupts. - Inside Einstein's Mind
E9Inside Einstein's MindOn November 25th, 1915, Einstein published his greatest work: general relativity. The theory transformed our understanding of nature’s laws and the entire history of the cosmos, reaching back to the origin of time itself. Now, in celebration of the 100th anniversary of Einstein’s achievement, NOVA tells the inside story of Einstein’s masterpiece. The story begins with the intuitive thought experiments that set Einstein off on his quest and traces the revolution in cosmology that is still playing out in today’s labs and observatories. Discover the simple but powerful ideas at the heart of relativity, illuminating the theory—and Einstein’s brilliance—as never before. From the first spark of an idea to the discovery of the expanding universe, the Big Bang, black holes, and dark energy, NOVA uncovers the inspired insights and brilliant breakthroughs of “the perfect theory.” - Secret Tunnel Warfare
E10Secret Tunnel WarfareDuring World War I, the Allies and Germans repeatedly struggled to break the hideous stalemate of trench warfare. In the winter of 1916, Allied engineers devised a massive surprise attack: over 1 million pounds of explosives hidden in secret tunnels driven under German lines. Building the tunnels was desperate work, with tunnelers at constant risk from flooding, cave-ins, and enemy digging teams. In June of 1917, the planted mines at Messines were simultaneously triggered, killing an estimated 10,000 German troops instantly. Now, archaeologists are revealing the extraordinary scale and risks of the Allied tunneling operations in one of the biggest excavations ever undertaken on the Western Front. “Secret Tunnel Warfare” opens a unique window on the frenzy of Allied mining activity that led up to the attack and its bitter aftermath. - Life's Rocky Start
E11Life's Rocky StartFour and a half billion years ago, the young Earth was a hellish place—a seething chaos of meteorite impacts, volcanoes belching noxious gases, and lightning flashing through a thin, torrid atmosphere. Then, in a process that has puzzled scientists for decades, life emerged. But how? NOVA joins mineralogist Robert Hazen as he journeys around the globe. From an ancient Moroccan market to the Australian Outback, he advances a startling and counterintuitive idea—that the rocks beneath our feet were not only essential to jump-starting life, but that microbial life helped give birth to hundreds of minerals we know and depend on today. It's a theory of the co-evolution of Earth and life that is reshaping the grand-narrative of our planet’s story. - Himalayan Megaquake
E13Himalayan MegaquakeOn April 25, 2015 a devastating earthquake rocked Nepal, wiping out villages and leaving thousands dead. Through eyewitness footage, expert interviews, and stunning graphics, NOVA reveals the anatomy of this megaquake while scientists race to answer urgent questions: Is another big one coming? - Vikings Unearthed
E18Vikings UnearthedThey were pioneering warriors, expert seafarers, and colonists of the North Atlantic realm. The Vikings even claimed in their sagas to have reached America. Now, renowned archaeologist Sarah Parcak uncovers new clues about their legendary expeditions and settlements. - Can Alzheimer's Be Stopped?
E19Can Alzheimer's Be Stopped?Alzheimer's ravages the minds of over 40 million victims worldwide. Join scientists as they untangle the cause of this tragic illness and go behind the scenes of major drug trials to discover the therapies that may slow and even prevent the disease.
