The book details astromonical discoveries from its roots during the earliest civilisations right through to its latest developments in the 21st century. It is excellently and richly illustrated, with many informative historical pictures, timelines, diagrams, computer representations, tables and, of course, photographs, including those of distinguished scientists, their discoveries and various astronomical features.
The text is informative, easily understandable and never dull. The story itself is compelling. There are many entertaining details concerning, for example, how the calendar was fine-tuned, how Bruno was burned by the Church for his supposedly heretical ideas (that the earth revolved around the sun, for one), the "problems" of Einstein's e=mc˛, and more.
A well researched and highly readable account.
