Maintaining its appealing style and presentation, the Yearbook of Astronomy 2023 contains comprehensive jargon-free monthly sky notes and an authoritative set of sky charts to enable backyard astronomers and sky gazers everywhere to plan their viewing of the year's eclipses, comets, meteor showers and minor planets as well as detailing the phases of the Moon and visibility and locations of the planets throughout the year. To supplement all this is a variety of entertaining and informative articles, a feature for which the Yearbook of Astronomy is known. Presenting the reader with information on a wide range of topics, the articles for the 2023 edition include, among others, The Incomparable Sir Patrick Moore; Shining a Light on Jupiter's Atmosphere; A Brief History of the End of the Universe; The Closing of Historic Observatories; The Ability to Believe: Bizarre Worlds of Astronomical Antireality; Optical SETI at Harvard; The Future of Spaceflight; and Male Family Mentors for Women in Astronomy: Caroline and William Herschel. This iconic publication made its first appearance way back in 1962, shortly after the dawning of the Space Age. Now into its seventh decade of production, the Yearbook continues to be essential reading for anyone lured and fascinated by the magic of astronomy and who has a desire to extend their knowledge of the Universe and the wonders it plays host to. The Yearbook of Astronomy is indeed an inspiration to amateur and professional astronomers alike, and warrants a place on the bookshelf of all stargazers and watchers of the Universe. AUTHOR: Brian Jones hails from Bradford in the West Riding of Yorkshire and was a founder member of the Bradford Astronomical Society. He developed a fascination for astronomy at the age of five when he first saw the stars through a pair of binoculars, and his interest took him into the realms of writing sky guides for local newspapers, appearing on local radio and television, teaching astronomy and space in schools and, in 1985, becoming a full time astronomy and space writer. He has penned around 20 books to date which have covered a range of astronomy and space-related topics for both children and adults. His passion for bringing an appreciation of the universe to his readers is reflected in his writing. 60 colour illustrations
