Book excerpt: During his younger days working as a bush mechanic and pearl diver in remote WA, Greg Quick spent countless nights lying in a swag and staring at the stars. That daily distraction grew into a passion that has seen him become one of Australia's best known and most engaging astronomers. In recent years Greg - aka 'Space Gandalf' - has taken on cult status among audiences via his appearances alongside Professor Brian Cox in the hit TV series Stargazing Live. Greg's practical explanations of the complexities of space have also earned him respect from astronomers around the world. Is The Moon Upside Down? is an absorbing guided tour of the cosmos as seen through Greg's eyes. Unlike many of his peers who studied at university he offers a unique and refreshing perspective on astronomy that was instead forged on cliff tops outside Alice Springs, in the endless expanse of the Great Sandy Desert, on the floor of the Indian Ocean and in his own front yard in Broome. No matter what mysteries you've pondered about Earth's astral dance with the Sun, planets, Moon and the stars, it's guaranteed Greg has thought about them too, and the answers can be found in the pages of this book.
