This book is a combination of the two seasons of Cosmos that Neil deGrasse Tyson hosted, his Star Talk TV show, and the Star Talk podcast/webisodes mixed together. The book was written by Tyson and co-author James Trefil. In it, Tyson explains what the various sciences (basically physics, chemistry, biology, and astrophysics) have figured out about the origin of the universe, the formation of our solar system, life on Earth, the possibility of alien life elsewhere in the universe, and how the universe may ultimately end. As importantly he goes through things that there is evidence for, but is not well understood (e.g., dark matter and dark energy). He is able to explain the concepts clearly without throwing a bunch of equations in the book that would require multiple years of calculus to even begin to understand. In fact, the only equation in the book is the famous Drake Equation that is used to try to predict the number of planets or moons that may have intelligent life, and even in that case, he is really just explaining what the variables in the equation represents.
The book is what I consider an intermediate length, at just over 300 pages. There are a lot of pictures in the book, both actual photographs taken through telescopes or the various probes we have sent out into the solar system, and artist renderings of how we think things look. And, some of the tweets that Tyson has tweeted over the years on various topics are included. So, the book reads fairly quickly. My only complaint is that throughout the book the authors include what amount to margin notes that delve a bit more deeply into something that was mentioned in the main text. However, the font used for these asides is smaller and the ink used is much lighter than the main text. So, unless you have really good eyesight, they can be hard to read, especially if you are at the point in your life where you need to use reading glasses or progressive lenses. That aside, it is still a good read for anyone who is interested in Astronomy and Astrophysics.
