The Space Book is massive in scope, covering the beginning of time to the supposed end of the universe. With beautiful illustrations and instructive diagrams, the 250 Milestones in Astronomy and Cosmology is wonderfully informative and interesting.

Although I suppose if you have read one of the books in this series, you will find more of the same here, only on a different subject. The format is pretty much the same, and a lot of bias enters into the mix since they have a limit of what can be covered. For instance, separate entries are given for each planetary discovery and for discoveries of other moons. This book also contains an entry on Einstein's "Miracle Year" of 1905. At first, I didn't understand why that was included, but I suppose the photoelectric effect and other discoveries would allow scientists to use other methods of detection. ( )
