A blinding flash of light streaked across the Russian sky, followed by a shuddering blast strong enough to damage buildings and send more than 1,000 people to the hospital. On the morning of February 15, 2013, a 7,000-ton asteroid crashed into the Earth’s atmosphere.

The elephant, Earth’s most charismatic and majestic land animal, today faces market forces driving the value of its tusks to levels once reserved for gold. In this groundbreaking National Geographic special, follow journalists Bryan Christy and Aidan Hartley as they go undercover and inside the criminal network behind ivory's supply and demand.
Crows live everywhere in the world except Antarctica and are a part of myths and legends in many cultures. Their reputation in the stories varies from comical to frightening, godlike or wise, bringers of light and bringers of death, though a “murder” of crows refers to a flock of crows, and not to anything murderous, at all. They may be all these things, but what we are learning is that they are especially smart.
Earth From Space is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet. Produced in extensive consultation with NASA scientists, NOVA takes data from earth-observing satellites and transforms it into dazzling visual sequences, each one exposing the intricate and surprising web of forces that sustains life on earth.
In Attenborough’s Life Stories, “Our Fragile Planet”, Sir David Attenborough reflects on the dramatic impact that we have had on the natural world during his lifetime, such as the disappearing rain forests and coral reefs, endangered species such as the blue whale, manatees, sea otters, chimpanzees, and orangutans. He notes how the vulnerable Panamanian golden frog is now quarantined for safety so it doesn’t succumb to a highly infectious fungus which has already made the Monteverde Toad from Costa Rica extinct.
In 1957, decades before Steve Jobs dreamed up Apple or Mark Zuckerberg created Facebook, a group of eight brilliant young men defected from the Shockley Semiconductor Company in order to start their own transistor business. Their leader was 29-year-old physicist with a brilliant mind and the affability of a born salesman who would co-invent the microchip -- an essential component of nearly all modern electronics today, including computers, motor vehicles, cell phones and household appliances.
In “Understanding the Natural World,” Sir David Attenborough shares his memories of the scientists and the breakthroughs that helped shape his own career. He also recalls some of his more hair-raising attempts to bring new science to a television audience: standing in the shadow of an erupting volcano as lumps of hot lava crashed around him or being charged by a group of armed New Guinean tribesmen.
Drones. These unmanned flying robots—some as large as jumbo jets, others as small as birds—do things straight out of science fiction. Much of what it takes to get these robotic airplanes to fly, sense, and kill has remained secret. But now, with rare access to drone engineers and those who fly them for the U.S. military, NOVA reveals the amazing technologies that make drones so powerful as we see how a remotely-piloted drone strike looks and feels from inside the command center.
In the Rocky Mountains, archeologists uncover a unique fossil site packed with astonishingly well-preserved bones of mammoths, mastodons, and other giant extinct beasts. The discovery opens a highly focused window on the vanished world of the Ice Age in North America.
One hundred thousand years ago, on planet Earth, huge sheets of ice surge and retreat. Now, a stunning find in an ancient lake promises a glimpse into this exotic Ice Age realm and at the fantastic creatures that ruled the land: ancient elephants like mammoths and mastodons; giant bison; sloths and camels.
Over 60,000 years ago, the first modern humans—people physically identical to us today—left their African homeland and entered Europe, then a bleak and inhospitable continent in the grip of the Ice Age. But when they arrived, they were not alone: the stocky, powerfully built Neanderthals had already been living there for hundreds of thousands of years.
So what happened when the first modern humans encountered the Neanderthals? Did we make love or war? That question has tantalized generations of scholars and seized the popular imagination.
