Sir Patrick Moore's new collection of Sky at Night articles covers the period from 2001 until early 2005. It is the 12th Sky at Night book (the second to be published by Philip's), and it accompanies the hugely successful BBC television series. Sir Patrick has presented the programme since it began in 1957, entering the record books as the longest-serving television presenter. The programme itself is the world's longest-running television series. The episodes have been turned into 40 highly readable and fully illustrated essays, which incorporate fascinating discussions between Sir Patrick and the leading astronomers who appear on the programme. The topics range across the whole spectrum of astronomy, space exploration and astrophysics, with essays on Unveiling Saturn and Titan, Galactic Whirlpools, Dobsonian Telescopes, the Transit of Venus, Gamma-Ray Bursters, and the Unseen Universe. All are illustrated with photographs from world-class telescopes and observatories, and space probes.
