Pale Blue Dot is about the Earth, humans, our place in the Cosmos, and the Solar System and our exploration of it. The title comes from the eponymous image taken by the Voyager 1 spacecraft. It tries to convey a sense of how small and fragile the Earth really is (if you want to get a real sense of it, I recommend Celestia), how the Universe really isn't made for us (sulfuric acid on Venus, for instance, or the black vacuum that covers most of the Universe), and how we've traditionally viewed the Universe. A large chunk of the book goes into explaining the exploration of our solar system and the findings we've made. It also advocates that we use the other planets as warnings for what may happen to our own if we spoil it (after all, so far this is the only place we've got).
This is a very engagingly-written account of the history of space flight, as well as a beautifully arranged advocacy of prudence when it comes to dealing with our planet.
