Light of the Stars: Alien Worlds and Fate Earth

Astrophysicist and NPR commentator Adam Frank reveals what the latest research on alien civilisations may tell us about our own. Light of the Stars tells a radically new story about what we are: one world in a universe awash in planets. Building on his widely discussed scientific papers and The New York Times op-eds, astrophysicist Adam Frank shows that not only is it likely that alien civilisations have existed many times before but that many of them have driven their own worlds into dangerous eras of change. He explains how dust storms on Mars, the greenhouse effect on Venus, Gaia Theory, the threat of nuclear winter, and efforts to prove or disprove the plurality of worlds from Aristotle to Copernicus to Carl Sagan have contributed to our understanding of our place in the universe and the growing challenge of climate change. And he explores what may be the largest question of all: if there has been life on other worlds, what its presence can tell us about our own fate.

**Winner of the 2019 Phi Beta Kappa Award for Science "A valuable perspective on the most important problem of our time." —Adam Becker, NPR** Light of the Stars tells the story of humanity’s coming of age as we realize we might not be alone in this universe. Astrophysicist Adam Frank traces the question of alien life from the ancient Greeks to modern thinkers, and he demonstrates that recognizing the possibility of its existence might be the key to save us from climate change. With clarity and conviction, Light of the Stars asks the consequential question: What can the likely presence of life on other planets tell us about our own fate?
