One of the most important recent finds in Biblical archaeology is uncovered in this National Geographic exclusive. The Gospel of Judas gives a different view of the relationship between Jesus and Judas, offering new insights into the disciple who betrayed Jesus. Unlike the accounts in the canonical Gospels of Matthew, Mark, Luke, and John, in which Judas is portrayed as a reviled traitor, this newly discovered Gospel portrays Judas as acting at Jesus' request when he hands Jesus over to the authorities.

In the spring of 2005, acclaimed environmental photographer James Balog headed to the Arctic on a tricky assignment for National Geographic: to capture images to help tell the story of the Earth's changing climate. Even with a scientific upbringing, Balog had been a skeptic about climate change. But that first trip north opened his eyes to the biggest story in human history and sparked a challenge within him that would put his career and his very well-being at risk. Chasing Ice is the story of one man's mission to change the tide of history by gathering undeniable evidence of our changing planet. Within months of that first trip to Iceland, the photographer conceived the boldest expedition of his life: The Extreme Ice Survey. With a band of young adventurers in tow, Balog began deploying revolutionary time-lapse cameras across the brutal Arctic to capture a multi-year record of the world's changing glaciers. As the debate polarizes America and the intensity of natural disasters ramps up globally, Balog finds himself at the end of his tether. Battling untested technology in subzero conditions, he comes face to face with his own mortality. It takes years for Balog to see the fruits of his labor. His hauntingly beautiful videos compress years into seconds and capture ancient mountains of ice in motion as they disappear at a breathtaking rate. Chasing Ice depicts a photographer trying to deliver evidence and hope to our carbon-powered planet.

This film documents, one of the least-known yet most remarkable pharaohs of ancient Egypt. Psusennes I, who reigned around 1000 BC, was buried in a casket of solid silver and surrounded by treasures which rival those of Tutankhamun; the tomb of Psusennes is the only pharaoh's tomb ever found which hadn't previously been entered by tomb-raiders. His remarkable story has been overlooked partly because the initial discovery was made in 1940, overshadowed by the outbreak of World War II.

In this global mega-doc, National Geographic tells the story of the 1980s like never before. An epic rollercoaster ride told through astonishing archive and dramatic reconstruction, The 80s features interviews with music and film superstars as well as titans of technology, business, media and politics. We'll bring you ten years of breakneck innovation, glamour, success, and ambition, all shot through fascinating trends. Welcome back to the 1980s.

Nonstop glamour and excess find a new poster girl in the 1980s when a hot young singer sees her chance to create her own brand. Madonna inspires countless girls across the globe to hit the nearest shopping mall to match her distinctive style. Young men with money to burn are buying into the young professional - or "yuppie" - lifestyle, and scooping up the latest expensive gadget: the cell phone. And, marketers learn an important lesson about the power of these new consumers in 1985 when Coca Cola's disastrous launch of New Coke threatens its position against Pepsi.

With the mantra "greed... is good," Gordon Gekko encapsulates the 1980's drive for excess and ruthless ambition in Oliver Stone’s "Wall Street" while big traders mirror his notoriously bad behaviour with insider trading and drug use in real life. In the 80s, CEOs see their salaries skyrocket while women struggle to overcome office boys' clubs. And, the quest to climb higher also leads to one of the '80s biggest tragedies, as NASA's Space Shuttle Challenger explodes during lift off, claiming the lives of all on board.

The 80s - often described as the decade when greed was good. But it also marked the beginning of a potent alliance between charity and celebrity. Huge events are staged to deal with the crisis of poverty abroad and at home. President Reagan has set out a vision of a better future for Americans in the famous campaign ad, Morning in America. His foreign policy, however, is paying dividends - he is breaking down barriers as he pushes for an end to the Cold War.

As the 1980s draw to a close, the Cold War might be thawing, but the Berlin Wall still stands. America deploys a powerful 'weapon' to hasten its fall: pop culture. American movies, TV shows, music, and even the news, carry U.S. values and ideas out to the world and into the Soviet Bloc, swaying hearts and minds.

This is the extraordinary untold story of the heroism and sacrifice of the New York Police Department's elite rescue squad on September 11.

It was the day before the day that changed everything... Moment by moment, relive the final day before 9/11 and the 'war on terror' became part of our everyday vernacular.

We explore the middle-to-late 2000s, as man-made and natural calamities interplay with technological and cultural marvels, such as the rise of the iPhone, the fall of the stock market and The Iraq War.
