Journalist, author and broadcaster, Stuart Clark has devoted his career to presenting the dynamic world of astronomy to the general public. He is a Fellow of the Royal Astronomical Society and a former Vice Chair of the Association of British Science Writers. In 2000, UK daily newspaper The Independent placed him alongside Stephen Hawking and the Astronomer Royal, Professor Sir Martin Rees, as one of the 'stars' of British astrophysics teaching. He divides most of his time between writing books and writing for the European Space Agency in his capacity as senior editor for space science, alongside producing features for the BBC and many publications. He has written seventeen books to date, selling more than 250,000 copies worldwide, which have been translated into twelve languages so far. He regularly lectures throughout the UK and, increasingly, across the world. www.stuartclark.com
