It is 400 years since Galileo first turned the newly invented telescope towards the heavens and saw things that few had ever seen before. His discoveries, along with those of his contemporaries, completely changed our view of the world. Since that time, there have been many revolutions in our understanding of the universe, some perhaps even more revolutionary than the ones from Galileo’s time. In this book, the author leads us through various recent advances in modern astronomy that have increased our understanding of the universe and seen it grow from a single Solar System full of intriguing worlds to a galaxy filled with other star systems and their own planets and, maybe even Earthlike worlds. This is a journey like no other. What is glimpsed through the author’s keyole is vast, breathtakingly beautiful, and sometimes utterly bizarre, certainly unfamiliar to those of us on Terra Firma. From the desolate plains of Mars and the frozen moons of the outer Solar System, from the Milky Way to the ends of the universe, the author reveals wonders often hard to describe and sometimes even harder to fathom, some of the enthralling secrets of the universe. This book focuses on some of the most important discoveries, but also discoveries which people are most interested in. It provides interviews with the people who made the discoveries and includes their own insight and analysis and asks some important questions on the prevalence of life, the future of modern astrophysical problems and what we might discover in the far off reaches of our Solar System.
