David Attenborough brings to life, in unprecedented detail, the last days of the dinosaurs. Palaeontologist Robert DePalma has made an incredible discovery in a prehistoric graveyard: fossilised creatures, astonishingly well preserved, that could help change our understanding of the last days of the dinosaurs. Evidence from his site records the day when an asteroid bigger than Mount Everest devastated our planet and caused the extinction of the dinosaurs. Based on brand new evidence, witness the catastrophic events of that day play out minute by minute.

NASA launches its most ambitious hunt for traces of life on Mars, landing a car-sized rover in a rocky, ancient river delta. The rover will stow samples for possible return to Earth and test technology that may pave the way for human travel to Mars.

Thundering across the sky on elegant white wings, the Concorde was an instant legend. But behind the glamour of jet setting at Mach 2 were stunning scientific innovations and political intrigue. Fifteen years after Concorde's final flight, this documentary takes you inside the historic international race to develop the first supersonic airliner. Hear stories from those inside the choreographed effort to design and build Concorde in two countries at once - and the crew members who flew her.

Astrophysicists show how black holes might hold answers to how the universe evolved, leading to life on Earth and, ultimately, the human race.

Could scientists recreate Hollywood's Jurassic Park using 100-million-year-old dinosaur DNA? Director Steven Spielberg, author Michael Crichton, actor Jeff Goldblum, and a host of scientific experts answer this compelling question in the award-winning Nova documentary, The Real Jurassic Park. Behind-the-scenes clips, interviews, and demonstrations with leading paleontologists investigate the viability of reviving the extinct species. All phases of logistics are addressed, including extracting prehistoric insect DNA, creating embryos for placement in host eggs, and more. The scientific analysis of the process leads to the examination of the ethics of recreating a vanished life form.

In 1889, Gustave Eiffel decides to attempt the impossible for the Universal Exhibition in Paris: to build the tallest tower in the world. Before this project, this pioneer and visionary had created more than 300 metal structures around the world.

Spacecraft OSIRIS-REx attempts to grab a piece of an asteroid to bring back to Earth so scientists can study it to learn about the planet's origins.

Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?

Predictions underlie nearly every aspect of our lives, from sports, politics, and medical decisions to the morning commute. With the explosion of digital technology, the internet, and 'big data,' the science of forecasting is flourishing. But why do some predictions succeed spectacularly while others fail abysmally? And how can we find meaningful patterns amidst chaos and uncertainty? From the glitz of casinos and TV game shows to the life-and-death stakes of storm forecasts and the flaws of opinion polls that can swing an election, 'Prediction by the Numbers' explores stories of statistics in action. Yet advances in machine learning and big data models that increasingly rule our lives are also posing big, disturbing questions. How much should we trust predictions made by algorithms when we don't understand how they arrive at them? And how far ahead can we really forecast?

For 25 centuries the Parthenon has been shot at, set on fire, rocked by earthquakes, looted for its sculptures, and disfigured by catastrophic renovations. To save it from collapse, the modern restoration team must uncover the secrets of how the ancient Greeks built this icon of western civilization in less than nine years without anything resembling an architectural plan.

A post-modern theater adaptation of a classic Greek tragedy takes place in a central theater of Athens. Like every night, the audience take their seats and the play begins. Suddenly, the lights on stage go out. A group of young people, dressed in black and carrying guns, come up on stage. They apologize for the interruption and invite people from the audience to participate on stage. The play resumes with a main difference; life imitates art and not the opposite.

Twenty-three bizarre looking vehicles line up at the starting gate of the DARPA Grand Challenge with one thing in common: there's nobody behind the wheel. Sponsored by the Pentagon's research agency, this race for robotic, driverless vehicles has a $2 million prize. Its ultimate goal is to gather new ideas for the future of unmanned warfare.

Murdered more than 5,000 years ago, Otzi the Iceman is the oldest human mummy on Earth. Now, newly discovered evidence sheds light not only on this mysterious ancient man, but on the dawn of civilization in Europe.

' Red string tied, wrapped in the creel, please turn kicks tale n'archinisei 'used to say older before they start their tales. But Knit Red Thread of Costas Charalambous does not narrate a tale but a nightmare that haunts the Greek history for more than 60 year. The nightmare of civil war.

In Egypt's Sahara Desert, massive skeletons with strange skulls and gigantic teeth jut out from the sandy ground. This fossil graveyard, millions of years old, is known as the "Valley of the Whales." Now, paleontologists have unearthed a whole new species of ancient whale dating to 43 million years ago, and this predator wasn't just able to swim – it also had four legs and could walk. Follow scientists as they search for new clues to the winding evolutionary path of mammals that moved from the land into the sea to become the largest animals on Earth.

Can we harness the power of artificial intelligence to solve some of the world’s most challenging problems without creating an uncontrollable force that ultimately destroys us? New A.I. tools like ChatGPT can now answer complex questions, write essays, and generate realistic-looking images in a matter of seconds. In NOVA “A.I. REVOLUTION,” correspondent Miles O’Brien meets some of the scientists who are at the forefront of A.I. advancement and explores the promise, perils, and possible future of this unprecedented technology taking the world by storm.

Leonardo da Vinci was a Renaissance genius. Not only did he paint masterpieces of art, but he was an obsessive scientist and inventor, dreaming up complex machines centuries ahead of his time, including parachutes, armored tanks, hang gliders and robots. On the 500th anniversary of Leonardo’s death, with the help of biographer Walter Isaacson, NOVA investigates the secrets of Leonardo’s success. How did his scientific curiosity, from dissections of cadavers to studies of optics, shape his genius and help him create perhaps the most famous painting of all time, the "Mona Lisa"?

Three million years ago, camels roamed through Greenland’s endless forests and our ancestors lived in the trees. It all came to an end with the Ice Ages. What died and what survived, as natural selection shaped the evolutionary tree during this epochal shift from hot to cold? Until now, scientists have known less about the natural world before the Ice Age than they did about the age of dinosaurs, which ended 64 million years ago. A new discovery is set to reveal this lost world, species by species. Led by Danish gene-hunter Eske Willerslev, a team of scientists for the first time in history is sequencing DNA from before the Ice Age. The picture that emerges is of a hot planet, when forests blanketed the Arctic and carbon levels matched those in our atmosphere today. Is this a portrait of our own climate future?

The events and coincidences that led to rapid advances in human intelligence 50,000 years ago.

Dinosaurs are generally considered tropical animals. So what are their fossils doing north of the arctic circle? Paleontologists battle the fierce climate to find out if the arctic was warmer then than it is now, or the arctic was farther from the North Pole, or the dinosaurs were migratory animals, or if they were warm-blooded.
