It’s a golden age for planet hunters: NASA's Kepler mission has identified more than 3,500 potential planets orbiting stars beyond our Sun. Some of them, like a planet called Kepler-22b, might even be able to harbor life. How did we come upon this distant planet?

It was the strongest cyclone to hit land in recorded history. On November 8, 2013, Typhoon Haiyan slammed into the Philippines, whipping the low-lying and densely-populated islands with 200 mph winds and sending a two-story-high storm surge flooding into homes, schools, and hospitals. It wiped villages off the map and devastated cities, including the hard-hit provincial capital Tacloban. Estimates count more than 5,000 dead and millions homeless. What made Haiyan so destructive? Meteorologists charged with tracking Pacific storms reveal why the Pacific is such fertile ground for cyclones, and NOVA’s film crew documents how conditions dramatically deteriorated in the storm’s aftermath, as impassable roads and shuttered gas stations paralyzed the critical relief effort, leaving food, water, and medicine to pile up at the airport. Disaster preparedness experts scramble to understand why the Philippines was so vulnerable. As climate change and sea level rise threaten millions of the world’s most impoverished people with stronger, and perhaps more frequent, storms, how can we prepare for the next monster typhoon?

The asteroid that exploded over Siberia—injuring more than 1,000 and damaging buildings in six cities—was a shocking reminder that Earth is a target in a cosmic shooting range. From the width of a football field to the size of a small city, these space rocks have the potential to be killers. In a collision with Earth, they could set off deadly blast waves, raging fires and colossal tidal waves. But some audacious entrepreneurs look up at asteroids and see payday, not doomsday. Some asteroids are loaded with billions of dollars’ worth of elements like iron, nickel, and platinum. NASA is planning an ambitious mission to return samples from a potentially hazardous asteroid, and would-be asteroid miners are dreaming up their own program to scout for potentially profitable asteroids. Will asteroids turn out to be our economic salvation—or instruments of extinction?

In the rolling hills of Ireland's County Tipperary, a laborer harvesting peat from a dried-up bog spots the remnants of a corpse and stops his machine just in time, revealing a headless torso almost perfectly preserved and stained dark brown by the bog. Archeologists recognize the corpse as one of Europe's rare bog bodies: prehistoric corpses flung into marshes with forensic clues often suggesting execution or human sacrifice. The corpse will eventually be dated to the Bronze Age, over 3,000 years ago. Many of these were victims of shocking violence, showing evidence of axe blows, hanging, and stab wounds. Like a crime thriller, NOVA follows archaeologists and forensic experts in their methodical hunt for clues to the identity and the circumstances of this and other violent deaths of bog body victims. A new theory emerges that they are those of ritually murdered kings, gruesomely slain to assure the fertility of land and people. NOVA’s ancient detective story opens a tantalizing window on the strange beliefs of Europe's long vanished prehistoric peoples.

Between the blue sky above and the infinite blackness beyond lies a frontier that scientists have only just begun to investigate. In "At the Edge of Space," NOVA takes viewers on a spectacular exploration of the Earth-space boundary that's home to some of nature's most puzzling and alluring phenomena: the shimmering aurora, streaking meteors, and fleeting flashes that shoot upwards from thunderclouds, known as sprites. Only discovered in 1989, sprites have eluded capture because they exist for a mere split-second—40-times faster than an eye blink. NOVA rides with scientists in a high-flying weather observation plane on a hunt for sprites, finally snaring them in 3D video and gaining vital clues to unraveling their mystery. Combining advanced video technology with stunning footage shot from the International Space Station, "At the Edge of Space" probes the boundary zone and offers an entirely new perspective on our home planet.
Tập 14
Beneath the streets of Rome lies a city of the dead known as the Catacombs—a labyrinth of tunnels, hundreds of miles long, lined with the neatly laid out tombs of the citizens of ancient Rome. Here, in 2002, maintenance workers fixing a broken water main stumbled upon a previously unknown burial chamber like none other in the complex. It was a mass grave of hundreds of bodies spread across six roughly carved caverns, locked away for nearly 2000 years. Who were these people? And can we discover, after all these centuries, what killed them? Could they be Christian martyrs massacred by the Emperor? Or were they felled by a deadly plague? In “Roman Catacomb Mystery,” NOVA’s forensic investigation follows a trail of ancient clues to uncover new secrets of life, death, and disease in the heyday of a mighty empire.
Tập 7
For decades, the assassination of John F. Kennedy has fueled dark rumors of conspiracies and mishandled evidence. Now, fifty years later, NOVA asks: Could modern investigators do better? We’ll see how state-of-the art forensic tools would be applied to the investigation were it to happen today. At the same time, NOVA takes a critical look at contemporary cases, like the murders of Nicole Brown Simpson and Ronald Goldman, to reveal how charges of evidence mishandling and human error can mar even scientifically sophisticated detective work.

The dome that crowns Florence’s great cathedral of Santa Maria del Fiore—the Duomo—is a towering masterpiece of Renaissance ingenuity and an enduring source of mystery. Still the largest masonry dome on earth after more than six centuries, it is taller than the Statue of Liberty and weighs as much as an average cruise ship. Historians and engineers have long debated how its secretive architect, Filippo Brunelleschi, managed to keep the dome perfectly aligned and symmetrical as the sides rose and converged toward the center, 40 stories above the cathedral floor. His laborers toiled without safety nets, applying novel, untried methods. Over 4 million bricks might collapse at any moment—and we still don’t understand how Brunelleschi prevented it. To test the latest theories, a team of U.S. master bricklayers will help build a unique experimental model Duomo using period techniques. Will it stay intact during the final precarious stages of closing over the top of the dome?
Tập 6
The world has always been a dangerous place, so how do we increase our odds of survival? In "Making Stuff Safer," David Pogue explores the cutting-edge research of scientists and engineers who want to keep us out of harm’s way. Some are countering the threat of natural disasters with new firefighting materials and safer buildings. Others are at work on technologies to thwart terrorist attacks. A next-generation vaccine will save millions from deadly disease. And innovations like smarter cars and better sports gear will reduce the risk of everyday activities. We’ll never eliminate danger—but science and technology are making stuff safer.
Tập 16
Over the last few centuries we have shot, trapped, and skinned the predators that formerly thrived at the top of the food chain in the wild. Wild bears, wolves, and big cats are all in retreat, and a growing number of scientists are discovering that by eliminating predators, we have changed the environment. Removing predators from the wild has thrown ecosystems off-kilter, triggering domino effects that scientists are just beginning to understand. In "Wild Predator Invasion," NOVA follows scientists who are trying a simple but controversial solution: returning apex predators—like wolves, bears, and panthers—to their natural environments. Can these newly reintroduced predators restore the natural balance of their ecosystems without threatening the humans who live among them?
Tập 5
Cold is the new hot in this brave new world. For centuries we've fought it, shunned it, and huddled against it. Cold has always been the enemy of life, but now it may hold the key to a new generation of science and technology that will improve our lives. In "Making Stuff Colder," David Pogue explores the frontiers of cold science from saving the lives of severe trauma patients to ultracold physics, where bizarre new properties of matter are the norm and the basis of new technologies like levitating trains and quantum computers.
Tập 17
When it comes to intelligence, we humans are clearly the most gifted animals around. But what make us so special? Is it our ability to make and use tools? To solve complex problems? Or plan for the future? It might seem that way, but today, researchers are discovering other creatures with impressive brains that have mastered all those skills. Surprisingly, many are bird brains. Crows bend and shape sticks to create custom-made spears for hunting grubs, and they are just one among a growing list of bird species whose impressive problem-solving abilities are shocking scientists and revolutionizing our understanding of animal intelligence. At the head of the class, we meet animals like Muppet, a cockatoo with a talent for picking locks; 007, a wild crow on a mission to solve an eight-step puzzle for the first time ever; and Bran, a tame raven who can solve a puzzle box so quickly that his performance has to be captured with high-speed photography. But are these skills really evidence of high intelligence, or just parlor tricks, the result of training and instinct? To find out, NOVA tests the limits of some of the planet’s brainiest animals, searching for the secrets of a problem-solving mind.
