Book read: Cosmos by Carl Sagan

I bought this book on the back of watching the iconic 1980s series Cosmos. It is an interesting and thought provoking read, covering similar areas to the series but going into more detail on some areas.

Clearly a big thing for Sagan is the search for extra terrestrial life and how we would go about it, or even recognise any signals we might receive. The book also gives a general treatment of scientific advance right through to Einstein's ground breaking work on relativity. It also analyses missions such as Voyager, and theoretical missions of how far we could travel in the vast distances of space.

Of course the book feels like a bit of history now, Sagan sadly died in 1996 at 62. He would have been fascinated by the continued discoveries like exoplanets and images from space telescopes.
