A celebration of the career of the musician, whose death from cancer was announced 11th Jan 2016. Bowie's work was the soundtrack to a generation and influenced countless musicians and this features memorable music videos and performances, as well as tributes from friends and fans around the world". Singer, songwriter, multi-instrumentalist, record producer, painter, and actor. He was a figure in popular music for over five decades, and was considered by critics and other musicians as an innovator, particularly for his work in the 1970s. Bowie's impact was enormous; he changed the nature of rock music, and changed his own approach repeatedly. During his career, he sold an estimated 140 million records worldwide. In the UK, he was awarded nine platinum album certifications, eleven gold and eight silver, and in the US received five platinum and seven gold certifications. He was inducted into the Rock and Roll Hall of Fame in 1996. Bowie stopped concert touring after 2004, and last performed live at a charity event in 2006. In 2013, he returned from a decade-long recording hiatus, remaining musically active until his death from liver cancer three years later.

Dash Snow rejected a life of privilege to make his own way as an artist on the streets of downtown New York City in the late 1990s. Developing from a notorious graffiti tagger into an international art star, he documented his drug- and alcohol-fueled nights with the surrogate family he formed with friends and fellow artists Ryan McGinley and Dan Colen before his death by heroin overdose in 2009.
Drawing from Snow's unforgettable body of work and involving archival footage, Cheryl Dunn's exceptional portrait captures his all-too-brief life of reckless excess and creativity.

Sir Roger Penrose is more than just a fan of MC Escher's mind-bending art. During the course of a long creative collaboration, the British mathematician and the Dutch artist exchanged ideas and inspirations. Some of Escher's most iconic images have their origin in Penrose's mathematical sketches - while the artist's work has served as a starting point for the professor's own explorations of new scientific ideas". To coincide with the first ever Escher retrospective in the UK, Penrose takes us on a personal journey through Escher's greatest masterpieces - marvelling at his intuitive brilliance and the penetrating light it still sheds on complex mathematical concepts.

For centuries, the precise workings of gravity have confounded the greatest scientific minds - from Newton to Faraday and Einstein - and the idea of controlling gravity has been seen as little more than a fanciful dream. Yet in the mid 1990s, UK defence manufacturer BAE Systems began a ground-breaking project code-named Greenglow. Nasa was simultaneously running its own Breakthrough Propulsion Physics Project". It was concerned with potential space applications of new physics, including concepts like 'faster-than-light travel' and 'warp drives'. Looking into the past and projecting into the future, Horizon explores science's long-standing obsession with the idea of gravity control. It looks at recent breakthroughs in the search for loopholes in conventional physics and examines how the groundwork carried out by Project Greenglow has helped change our understanding of the universe. Gravity control may sound like science fiction, but the research that began with Project Greenglow is very much ongoing, and the dream of flying cars and journeys to the stars no longer seems quite so distant.

In part two, Professor Al-Khalili looks at the 19th century chemists who struggled to impose an order on the apparently random world of the elements. From working out how many there were to discovering their unique relationships with each other, the early scientists' bid to decode the hidden order of the elements was driven by false starts and bitter disputes. But ultimately the quest would lead to one of chemistry's most beautiful intellectual creations - the periodic table.

Professor Brian Cox tackles some of the most challenging and intriguing questions facing science. He looks back on a decade of discovery and towards the next space frontier.
Brian believes we are at the start of a new age of space travel, where space flight is on the verge of becoming routine. In this episode, he explores the latest science and takes a new look at his old films and asks: how far can we go in our exploration of the cosmos?
