As the geological structure and formation of other planets becomes better
known, the Earth is increasingly seen from a planetary perspective. Jonathan
Lunines’s Earth: Evolution of A Habitable World provides an excellent,
up-to-date introduction to this way of looking at our world. It should prove
attractive to the new generation of cosmological rock enthusiasts. Published by
Cambridge University Press, £19.95/$29.95, ISBN 0521644232.
