In 1900, a storm blew a boatload of sponge divers off course and forced them to take shelter by the tiny Mediterranean island of Antikythera. Diving the next day, they discovered a 2,000 year-old Greek shipwreck. Among the ship's cargo they hauled up was an unimpressive green lump of corroded bronze. Rusted remnants of gear wheels could be seen on its surface, suggesting some kind of intricate mechanism. The first X-ray studies confirmed that idea, but how it worked and what it was for puzzled scientists for decades. Recently, hi-tech imaging has revealed the extraordinary truth: this unique clockwork machine was the world's first computer. An array of 30 intricate bronze gear wheels, originally housed in a shoebox-size wooden case, was designed to predict the dates of lunar and solar eclipses, track the Moon's subtle motions through the sky, and calculate the dates of significant events such as the Olympic Games. No device of comparable technological sophistication is known from anywhere in the world for at least another 1,000 years. So who was the genius inventor behind it? And what happened to the advanced astronomical and engineering knowledge of its makers? NOVA follows the ingenious sleuthing that finally decoded the truth behind the amazing ancient Greek computer.

In September 2024, Hurricane Helene dumped more than 14 inches of rain on North Carolina, triggering flash floods and mudslides, causing over $50 billion of damage, and killing more than 100 people. A shocked nation wondered how the city that bore the brunt of the destruction – Asheville, at 2,000 feet above sea level and more than 250 miles inland – could have suffered such a fate. With eyewitness testimony, dramatic unseen videos, drone flyovers, and 3D animations, NOVA pieces together a moment-by-moment account of the Asheville disaster. And it looks to other recent flash floods – including the devastating Fourth of July 2025 floods in the Texas Hill Country, and catastrophic flooding in Valencia, Spain – for lessons that might help prevent the next disaster. Are these violent floods becoming more frequent and ferocious? And what can communities do to protect themselves in the future?

Ultimate Crash Test: Countdown
Surprisingly little is known about the behavior of cars and drivers in uncontrolled, real-world accidents, despite rigorous testing in laboratory-controlled crashes. Now, a first-of-its-kind experiment aims to discover what really happens in a multi-vehicle pileup and how cars and driving could be made safer.In the first episode of this two-part special, go behind the scenes as scientists make a series of high-stakes decisions to ensure the ambitious experiment goes off without a hitch. They only have one shot. The plan is for 8 drivers to drive 8 different cars by remote control at 70 mph down a hazardous straightaway. But how can they best represent real-world conditions to create a crash, especially when the drivers have no idea what's about to happen? How do they ensure that the remote drivers feel natural behind the wheel? And what is needed to fully capture every data-point possible? The intense preparation for the most ambitious crash test ever conducted culminates in the moment of truth as the cars barrel down an airport tarmac and collide in a massive, multi-vehicle pile-up.

Surprisingly little is known about the behavior of cars and drivers in uncontrolled, real-world accidents, despite rigorous testing in laboratory-controlled crashes. Now, a first-of-its-kind experiment aims to discover what really happens in a multi-vehicle pileup and how cars and driving could be made safer.In the second episode of this two-part special, forensic analysis is put to the test. Real-life crash scene investigations have very little data to work with, so are they accurate? And what can we learn about car safety when there is actual data to show exactly what happened? Follow scientists, engineers, and accident investigators as they analyze a treasure trove of data – more than they've ever been able to work with before. Interviews with drivers offer valuable clues into what they saw and how they reacted, and a LIDAR scan of the scene is stitched together into a digital version of the entire event that can be analyzed millisecond by millisecond. In this unprecedented look at a major multi-vehicle accident, discover insights about driver behavior and vehicle design that could save lives.

A half-century after American astronauts walked on the Moon, NASA and its international partners are taking the dream of Apollo a giant step further. In the coming years, the Artemis missions – named after Apollo's twin sister in Greek mythology – aim to bring astronauts back to the Moon and establish a lunar space station for scientific and commercial exploration. Follow the four members of the Artemis II crew as they embark on a perilous 10-day journey to orbit the Moon, venturing beyond Earth orbit for the first time since Apollo and farther into the Solar System than any humans have gone before. And get an inside look at the preparations needed to overcome the extreme engineering challenges of human-crewed spaceflight, all the way from launch to splashdown.Correction: This film previously stated that the four engines of the core stage generate 8.8 million pounds of thrust at liftoff. In fact, that much thrust is generated by the entire rocket including the boosters, not the core stage alone. The film has been updated accordingly.

Solar System: Wandering Worlds
The classic view of our solar system contains eight orderly planets, some with moons in neat orbits – but when we look closer, we discover a bunch of stuff missing from this simple, clockwork model. Wandering worlds that seem out of place, found in the gaps between and beyond the planets, offer clues that our cosmic neighborhood is far more dynamic than we once thought. From the meteorites that impact Earth, to a moon that orbits backwards, to an imposter lurking in the asteroid belt, these wandering worlds are rewriting what we know – and even how we think about – our solar system.

Around 300,000 years ago, Homo sapiens emerged in Africa – one of at least seven human species alive at the time. Now, we are the only remaining human line, and our impact on the planet is undeniable.In this stunningly cinematic five-part series, paleoanthropologist Ella Al-Shamahi takes viewers back in time to trace the surprising story of human origins. Remarkable new fossil evidence, modern DNA sequencing, and other cutting-edge scientific tools are shedding new light on the lives and journeys of long-vanished human species, and how our encounters with them helped make us who we are today. This evidence also reveals how our ancestors survived as they encountered new landscapes, developing the physical and cultural tools to help them survive – and eventually, with the rise of cities and complex civilizations, thrive – as no species has ever done.

How big is the universe? If it began with the Big Bang, will it also have an end? Is there life beyond our planet? Questions like these inspired the launch of Voyager I in 1977 and have driven innovative space research and exploration ever since. Trace the ground-breaking discoveries that have transformed our picture of the universe, from an age when we knew of no planets beyond our solar system, to today, when we have evidence of thousands and estimate trillions more. And follow the teams trying to solve two of the biggest mysteries in cosmology today: What are dark matter and dark energy?

Contrary to popular belief, dinosaurs never went extinct. They're still alive among us – in the form of birds! Birds are the only dinosaurs that survived the cataclysmic mass extinction caused by an asteroid the size of Mt. Everest crashing into Earth about 66 million years ago. The big question is: How? How did birds manage to not only live through the apocalypse, but also go on to diversify and populate every corner of our planet? Now, rare fossil discoveries are revealing the secrets of bird evolution going back more than 100 million years, telling the story of how some resilient feathered dinos persevered and transformed into the vast array of colorful bird species that fill our skies today.

On a remote hillside in modern-day Turkey sits Gpbekli Tepe, the oldest temple on Earth. For centuries, archaeologists believed it was a religious center built by nomadic hunter-gatherers before the rise of civilization. But groundbreaking new evidence reveals that a sophisticated community of settled hunter-gatherers, not nomads, lived here year-round for centuries. This startling discovery could be the missing link in humanity's momentous transition from hunting to farming. Follow experts as they use new digs and shattered skulls to piece together a captivating story that could forever change our understanding of the roots of civilization.
