He was a friend of Queen guitarist and astrophysicist Brian May, who was an occasional guest on "The Sky at Night". May bought Moore's Selsey home in 2008, leasing it back to him for a peppercorn rent the same day to provide financial security. May, Moore and Chris Lintott co-wrote a book "Bang! The Complete History of the Universe". In February 2011, Moore completed (with Robin Rees and Iain Nicolson) his comprehensive "Patrick Moore's Data Book of Astronomy" for Cambridge University Press. In 1986 he was identified as the co-author of a book published in 1954 called "Flying Saucer from Mars", attributed to Cedric Allingham, which was intended as a money-making venture and practical joke on UFO believers; Moore never admitted his involvement. He once joined the Flat Earth Society as an ironic joke.
