The Sky at Night book series, formerly published by Philips, documents the 40 most recent episodes of Sir Patrick Moore's record-breaking TV program of the same name. This program is the only major long-running TV program featuring astronomy topics in both the U.S. and the U.K. Each episode reviews current events and hot topics in the field of astronomy. As in the twelve earlier volumes, each of the episodes has been re-written into short, punchy essays from the past four years of broadcasting. Each chapter covers the subject of a particular show in The Sky at Night TV series. As such, this book presents a synopsis of the most significant events in astronomy during this 40-episode period. Patrick Moore has fans the world over, for whom these volumes are essential reading. The Sky at Night programs (and, of course, the books) feature many of the greatest living astronomers, astrophysicists, cosmologists, and astronauts - people such as Sir Martin Rees (President of the U.K.'s prestigious Royal Society, and Astronomer Royal), Prof. Gerry Gilmore, astronaut Eugene Cernan, and many more. Chris Lintott, the co-star of the latest episodes of Sky at Night, has a massive fan base that derives equally from The Sky at Night and from his paradigm-shifting astronomy website Galaxy Zoo, which has some 150,000 members.
