In You Are Here, celebrated astronaut Chris Hadfield gives us the really big picture: this is our home, as seen from space.The millions of us who followed Hadfield's news-making Twitter feed from the International Space Station thought we knew what we were looking at when we first saw his photos.But we may have caught the beauty and missed the full meaning.Now, through photographs – many of which have never been shared – Hadfield unveils a fresh and insightful look at our planet.He sees astonishing detail and importance in these images, not just because he's spent months in space but because his in-depth knowledge of geology, geography and meteorology allows him to reveal the photos' mysteries. Featuring Hadfield's favourite images, You Are Here is divided by continent and represents one (idealized) orbit of the ISS.Surprising, thought-provoking and visually delightful, it opens a singular window on our planet, using remarkable photographs to illuminate the history and consequences of human settlement, the magnificence of never-before-noticed landscapes, and the power of the natural forces shaping our world and the future of our species.
