Acclaimed National Geographic photographer James Balog was once a skeptic about climate change. But through his Extreme Ice Survey, he discovers undeniable evidence of our changing planet. In Chasing Ice, Balog deploys revolutionary time-lapse cameras to capture a multi-year record of the world's changing glaciers". His hauntingly beautiful videos compress years into seconds and capture ancient mountains of ice in motion as they disappear at a breathtaking rate. Traveling with a team of young adventurers across the brutal Arctic, Balog risks his career and his well-being in pursuit of the biggest story facing humanity. As the debate polarizes America, and the intensity of natural disasters ramps up globally, Chasing Ice depicts a heroic photojournalist on a mission to deliver fragile hope to our carbon-powered planet.

We think of comets as beautiful glowing balls of light streaking across our skies with their long sweeping tails, yet comets are so much more than just a cosmic firework display. Comets have a uniquely important place in modern science. As time machines from the early universe, they could hold the key to unlock the secrets of the cosmos. Comets could even be the origin of life itself. We follow the incredible odyssey of a comet as it sails through the solar system, watching it's every move as it evolves from a dormant chunk of ice and rock into a tumbling, violently active nucleus engulfed in a gaseous haze. What we learn is a revelation; comets are even more mysterious and fascinating than we had ever imagined.

Many consider it the greatest team ever assembled, in any sport. Yet even that description fails to give it proper credit for its impact. The original the Dream Team, the first U.S. Olympic team to include NBA stars was a phenomenon on and off the court. It mattered not that it dominated the Olympic competition. It won the gold medal at the 1992 Olympics in Barcelona, beating its eight opponents by an average of 44 points. What was important was that the Dream Team, gave fans a glimpse of basketball at its finest, and an entire world responded. The film is the definitive documentary of the historic 1992 USA Basketball team, featuring recent interviews with all 12 members, including Michael Jordan, Magic Johnson, Larry Bird, and Charles Barkley. Includes rare footage from USA Basketball's film library, and the untold story behind what has become part of basketball legend. Since 1992, basketball has exploded in popularity around the globe, rising to a place where it truly challenges soccer's status as the world's most popular sport. Much of that is due to the impact of the Dream Team, which attracted fans and followers wherever it went. "It was," said Coach Chuck Daly, "like Elvis and the Beatles put together. Traveling with the Dream Team was like traveling with 12 rock stars. That's all I can compare it to." And what a band it was. Start with three of the game's all-time greats: Michael Jordan, Magic Johnson and Larry Bird. Add the irrepressible Charles Barkley for a little spice, as well as seven more NBA All-Stars: centers David Robinson and Patrick Ewing, power forward Karl Malone, swingmen Scottie Pippen, Chris Mullin and Clyde Drexler and point guard John Stockton. Complete the roster with Christian Laettner, the best college player of 1991-92 and a future NBA All-Star. Opponents didn't have a chance, but they didn't care.

Push the limits of your imagination as astronomers attempt to grasp the mind-boggling extremes of size, distance and speed within our universe by bringing them down to earth. In this episode, our cast uses awesome analogies to bring the biggest objects, farthest distances and fastest speeds down to earth. To truly understand the scale of the cosmos, we jump behind the wheel of monster trucks, scale the Golden Gate Bridge, and race across the desert in a rocket-powered car.

Titanic 100 Years combines stunning imagery of the wreck with powerful untold stories of passengers and crew, letting audiences experience the real life drama of Titanic in a way never before possible. In 2010, an unprecedented expedition by Woods Hole Oceanographic Institute and RMS Titanic, Inc. went on location to document the entire wreck site of Titanic, using high-resolution optical video, sonar, acoustic imaging, and 3D HD video and acoustic modeling.
These incredible visuals are accompanied by the untold stories of people who were on the ship and linked with one or more recovered artifacts that connect to that passenger or crewmember. These haunting artifacts and unforgettable personal stories of average people take viewers back in time, making the history of Titanic as vivid as it was yesterday.

The human eye is a remarkable piece of precision engineering, but it is also extremely limited. Beyond the narrow range of light that makes up the familiar colours of the rainbow is a vast spectrum of light, entirely unseen. Richard Hammond does just that, using ground-breaking new imaging technologies to take the viewer on a breath-taking journey of discovery beyond the visible spectrum, seeing the world, quite literally, in a whole new light. From death-defying aerial repairmen in the United States using ultraviolet cameras to seek out an invisible force that lurks unseen on power lines, to German scientists unlocking the secrets of animal locomotion with the world's most powerful moving x-ray camera, to infrared cameras that can finally reveal the secrets within a humble beehive, he shows how new technologies are letting us see our world anew.
