Gr 7 Up A history of our understanding of these ``hairy stars'' from ancient times to the present, with almost equal treatment given to Halley's Comet and comets in general. There are many color illustrations and star charts for locating Halley's Comet and meteor showers. The space probes being sent by Japan, Russia and the European Space Agency are discussed in some detail. Theories on what comets are, ideas on how they originated and practical advice on how to observe Halley's Comet and meteor showers are included. Procedures for building a model comet and a three-dimensional chart to position the Earth and Halley's Comet in space are outlined.Dennis Ford, Canandaigua Junior Academy Library, N . Y .
