NASA may have just gotten one step closer to the answering the question: are we alone? The Spitzer Telescope has made a groundbreaking discovery of exoplanets that could be similar to our own. And as Kepler also continues its search, our understanding of the universe continues to be redefined.

There are some who believe that Darwin's theory of evolution has weakened religion. Conor Cunningham argues that nothing could be further from the truth.He travels to the Middle East where he shows that from the very outset, Christianity warned against literal readings of the biblical story of creation. In Britain, he reveals that, at the time, Darwin's theory of evolution was welcomed by the Anglican and Catholic Churches. Instead, he argues that the conflict between Darwin and God was manufactured by American creationists in the 20th century for reasons that had very little to do with science and religion and a great deal to do with politics and morality. Finally, he comes face to face with some of the most eminent evolutionary biologists, geneticists and philosophers of our time to examine whether the very

In 1971, after being rejected by Hollywood, Bruce Lee returned to his parents' homeland, Hong Kong. Over the next two years, he'd complete four iconic films that would define his legacy, a legacy cut short when he died, stunningly, in the summer of 1973. He was 32 years old. Directed by Bao Nguyen, 'Be Water' is a gripping, fascinating, intimate look at not just those final, defining years of Lee's life, but the complex, often difficult, and seismic journey that led to Lee's ultimate emergence as a singular icon in the histories of film, martial arts, and even the connection between the eastern and western worlds.
The film chronicles Lee's earliest days, as the son of a Chinese opera star born while his father was on tour in San Francisco, and then raised in Hong Kong over what became an at times troubled childhood. Sent to live in America at the age of 18, he began teaching Kung Fu in Seattle, and established a following that included his future wife, Linda. His ambition ever rising, Lee eventually made his way to Los Angeles, where he strove to break into American film and television. There, despite some success as a fight choreographer and actor, it was clear Hollywood wasn't ready for an Asian leading man - and so he returned to Hong Kong to make the films that would in fact make him a legend, his international star skyrocketing just as his life was cut short.
'Be Water' is told by the family, friends, and collaborators who knew Bruce Lee best, with an extraordinary trove of archive film providing an evocative, immersive visual tapestry that captures Lee's charisma, his passion, his philosophy, and the eternal beauty and wonder of his art.

In the third programme of the series, Aleks gives the lowdown on how, for better and for worse, commerce has colonized the web - and reveals how web users are paying for what appear to be 'free' sites and services in hidden ways. Joined by some of the most influential business leaders of today's web, including Eric Schmidt (CEO of Google), Chad Hurley (CEO of YouTube), Bill Gates, Martha Lane Fox and Reed Hastings (CEO of Netflix), Aleks traces how business, with varying degrees of success, has attempted to make money on the web. She tells the inside story of the gold rush years of the dotcom bubble and reveals how retailers such as Amazon learned the lessons. She also charts how, out of the ashes, Google forged the business model that has come to dominate today's web, offering a plethora of highly attractive, overtly free web services, including search, maps and video, that are in fact funded through a sophisticated and highly lucrative advertising system which trades on what we users look for. Aleks explores how web advertising is evolving further to become more targeted and relevant to individual consumers. Recommendation engines, pioneered by retailers such as Amazon, are also breaking down the barriers between commerce and consumer by marketing future purchases to us based on our previous choices. On the surface, the web appears to have brought about a revolution in convenience. But, as companies start to build up databases on our online habits and preferences, Aleks questions what this may mean for our notions of privacy and personal space in the 21st century

Iain sets sail on one of the fastest racing boats ever built to explore the story of our turbulent relationship with the wind. Travelling to iconic locations including the Sahara desert, the coast of West Africa and the South Pacific, Iain discovers how people have exploited the power of the wind for thousands of years. The wind is a force which at first sight appears chaotic. But the patterns that lie within the atmosphere have shaped the destiny of continents, and lie at the heart of some of the greatest turning points in human history.

Carl Sagan teaches students in a classroom in his childhood home in Brooklyn, New York, which leads into a history of the different mythologies about stars and the gradual revelation of their true nature. In ancient Greece, some philosophers (Aristarchus of Samos, Thales of Miletus, Anaximander, Theodorus of Samos, Empedocles, Democritus) freely pursue scientific knowledge, while others (Plato, Aristotle, and the Pythagoreans) advocate slavery and epistemic secrecy.
