The Cool Universe

The Cool Universe is the name astronomers give to the matter between the stars.These great clouds of dust and gas are not hot enough to be detected by optical telescopes.But over the last few decades, they have increasingly become the focus of infrared telescopy.Astronomers had long encountered dark, apparently starless patches in the night sky. When they discovered that these were actually areas obscured by dust, they found a way to see through these vexing barriers, using infrared telescopes, to the light beyond.However, more recently, the dust itself has become a source of fascination.The picture now being revealed by infrared astronomy is of a universe that is dynamic.In this dynamic universe, matter is recycled - and so the dust and gas of the Cool Universe play a vital role. They are the material from which the stars are created, and into which they finally disintegrate, enriching the reservoir of cool matter from which new stars will eventually be formed. As a result of the new research, we are now beginning to see first-hand the way our planet was formed when the solar system was born.With:Carolin CrawfordMember of the Institute of Astronomy, and Fellow of Emmanuel College, at the University of CambridgePaul MurdinVisiting Professor of Astronomy at Liverpool John Moores University's Astronomy Research InstituteMichael Rowan-RobinsonProfessor of Astrophysics at Imperial College, LondonProducer: Phil Tinline.

Politics in the 20th Century

Politics in the 20th Century

Melvyn Bragg talks to Gore Vidal and Alan Clarke about the future of the nation-state; is the concept dead and buried? And what is the relationship between politics and morality - have salaciousness and self-righteousness taken over where seriousness of intent and a strong nerve left off, or was it ever thus? With Gore Vidal, American writer, commentator and author of The Smithsonian Institution; Alan Clarke, historian, politician and author of The Tories: Conservatives and the Nation State, 1922-97.

War in the 20th Century

War in the 20th Century

In the first programme of a new series examining ideas and events which have shaped thinking in philosophy, religion, science and the arts, Melvyn Bragg and guests discuss warfare and human rights in the 20th century. He talks to Michael Ignatieff about the life of one of the 20th century’s leading philosophers, Isaiah Berlin, and to Sir Michael Howard about the 20th century will be remembered; as a century of progress or as one of the most murderous in history. When we see pictures on television of starving people in war torn areas most of us feel we must ‘do’ something. Where does the feeling that we are in some way responsible for our fellow human beings originate historically? How has technology affected the concept of the Just War? And what are the prospects for world peace as we enter the next century? With Michael Ignatieff, writer, broadcaster and biographer of Isaiah Berlin; Sir Michael Howard, formerly Regius Professor of History, Oxford University and joint editor of the new Oxford History of the Twentieth Century.
