Deep in a South African cave, an astounding discovery reveals clues to what made us human
NOVA 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
A team of historians and expert boat builders investigates the fascinating Noah's Ark flood legend and sets out to rebuild a tantalizing, ancient forerunner of the Ark
NOVA examines the science and technology behind cyber warfare and asks if we are already in the midst of a deadly new arms race
NOVA 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
The 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
How 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
The 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
On 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
During 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
Four 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
Tiny, transparent, and threatened, krill are crucial to the Antarctic ecosystem. But the population of krill is crashing for reasons that continue to baffle the experts. A leading theory says that krill’s life cycle is driven by an internal body clock that responds to the waxing and waning of the Antarctic ice pack, and as climate change alters the timing of the ice pack, their life cycle is disrupted
On April 25, 2015, a devastating earthquake rocked Nepal. As it ripped across the Himalayas, it wiped out villages and left thousands dead. Hear the harrowing stories of the Nepalese people who lived near the epicenter and of survivors trapped on Everest
On a summer’s night, there’s nothing more magic than watching the soft glow of fireflies switching on and off. Few other life forms on land can light up the night, but in the dark depths of the oceans, it’s a different story: nearly 90% of all species shine from within. Whether it’s to scare off predators, fish for prey, or lure a mate, the language of light is everywhere in the ocean depths, and scientists are finally starting to decode it
Memory is the glue that binds our mental lives. Without it, we’d be prisoners of the present, unable to use the lessons of the past to change our future. From our first kiss to where we put our keys, memory represents who we are and how we learn and navigate the world
He was stalked, attacked and left to die alone. Murdered more than 5,000 years ago, Otzi the Iceman is Europe’s oldest known natural mummy. Miraculously preserved in glacial ice, his remarkably intact remains continue to provide scientists, historians, and archeologists with groundbreaking discoveries about a crucial time in human history
Machines are everywhere. They run our factory assembly lines and make our coffee. But humanoid robots—machines with human-like capabilities—have long been the stuff of science fiction
