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.
