Discovered 18 months ago, Comet Hale-Bopp has grown steadily larger and brighter as it approaches the Sun and Earth. It will be numbered among the great comets of our lifetime. Comet Hale-Bopp will be at its best from January to May 1997. It promises to be an outstanding sight, visible anywhere on Earth (although especially fine for the northern hemisphere). For everyone interested in seeing this new celestial wonder, here's a detailed guide to the coming apparition: how to see the comet, what to look for, how to photograph it - even how to discover a comet on your own. Fully illustrated in colour, this book also explains what comets are and tells of their place in the solar system and human civilization.
