Earth From Space
"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. Viewers witness how dust blown from the Sahara fertilizes the Amazon; how a vast submarine "waterfall" off Antarctica helps drive ocean currents around the world; and how the Sun's heating up of the southern Atlantic gives birth to a colossally powerful hurricane. From the microscopic world of water molecules vaporizing over the ocean to the magnetic field that is bigger than Earth itself, the show reveals the astonishing beauty and complexity of our dynamic planet.

Secrets of the Sun
It contains 99.9 percent of all the matter in our solar system and sheds hot plasma at nearly a million miles an hour. The temperature at its core is a staggering 27 million degrees Fahrenheit. It convulses, it blazes, it sings. You know it as the sun. Scientists know it as one of the most amazing physics laboratories in the universe. Now, with the help of new spacecraft and Earth-based telescopes, scientists are seeing the sun as they never have before and even recreating what happens at its very center in labs here on Earth. Their work will help us understand aspects of the sun that have puzzled scientists for decades. But more critically, it may help us predict and track solar storms that have the power to zap our power grid, shut down telecommunications, and ground global air travel for days, weeks, or even longer. Such storms have happened before—but never in the modern era of satellite communication. "Secrets of the Sun" reveals a bright new dawn in our understanding of our nearest star—one that might help keep our planet from going dark.
Secrets of the Sun
With new tools, scientists are striving to better grasp our star and its potentially widely destructive solar storms.

Japan's Killer Quake
In its worst crisis since World War II, Japan faces disaster on an epic scale: a death toll likely in the tens of thousands, massive destruction of homes and businesses, shortages of water and power, and the specter of nuclear meltdown. With exclusive footage, NOVA captures the unfolding human drama and offers a clear-headed investigation of what triggered the earthquake, tsunami, and subsequent nuclear crisis. Can science and technology ever prevent devastation in the face of overwhelmingly powerful forces of nature?

Extreme Cave Diving
Follow a fearless team of scientists as they venture into blue holes—underwater caves that formed during the last ice age, when sea level was nearly 400 feet below what it is today. These caves, little-known treasures of the Bahamas, are one of Earth's least explored and most dangerous frontiers. The interdisciplinary team of biologists, climatologists, and anthropologists discover intriguing evidence of the earliest human inhabitants of the islands, find animals seen nowhere else on Earth, and recover a remarkable record of the planet's climate.

Deadliest Volcanoes
Millions of people around the world live in the shadow of active volcanoes. Under constant threat of massive volcanic eruptions, their homes and their lives are daily at risk from these sleeping giants. From Japan's Mount Fuji to the "Sleeping Giant" submerged beneath Naples to the Yellowstone "supervolcano" in the United States, we will travel with scientists from around the world who are at work on these sites, attempting to discover how likely these volcanoes are to erupt, when it might happen, and exactly how deadly they could prove to be.

What's the Next Big Thing?
In this episode of NOVA scienceNOW, come face to face with social robots that understand human feelings, carry on conversations, even make jokes. Then travel to Haiti, where geologists investigate the 2010 earthquake not long after it struck for clues to how to better forecast future quakes. Afterwards, join engineers at General Motors who are testing tiny, two-wheeled cars called EN-Vs, which one day might drive themselves through city streets. Learn about proposals for making our outdated electric grid "smart." And meet Nebraska native Jay Keasling, a pioneer in synthetic biology who shares his work on developing "designer" microbes that produce biofuels and medicines.
What's the Next Big Thing?
Greet the future: social robots, a "smart" electric grid, microbes that make diesel fuel, and more.

Mt St Helens: Back From the Dead
One of the most violent natural disasters of our time, the colossal eruption of Mt. St. Helens in 1980 blasted away an entire mountainside. Over 200 square miles of pristine forest were buried under millions of tons of lava, ash, mud, and avalanche debris. How could life ever return to this barren moonscape? A lone ecologist, Charlie Crisafulli, spent months in the blast zone and was astonished and puzzled by how quickly plants and animals colonized the wasteland. In this program, stunning cinematography and time-lapse photography trace the dramatic story of how Crisafulli witnessed life's return and figured out the puzzle. Now another question arises: How soon could another catastrophic eruption occur?
