Jupiter is an extraordinarily colourful and dynamic planet. Over minutes, one can watch tiny shadows cast by its moons slide over its surface; over days and weeks parades of diverse, giant swirling storms can be seen to move and evolve. It is because of this richness of visual and physical properties that Jupiter has intrigued amateur and professional astronomers and has been the goal of several space missions. This highly illustrated volume provides a comprehensive and accessible account of Jupiter and its satellites. It reviews systematic telescopic observations that have stretched over more than a hundred years, in addition to modern observations and theories, and the wealth of data from the Pioneer, Voyager and Ulysses space missions. As well as a thorough survey of the planet's atmosphere, this volume presents an up-to-date account of our present knowledge of Jupiter's satellites and magnetosphere, at a level accessible to the non-specialist. This volume provides the definitive account of Jupiter for advanced amateur astronomers, professional astronomers and planetary scientists.
