Taxi drivers love to talk, and when astrobiologist Charles Cockell is their passenger, they love to talk about aliens. This humorous, insightful collection gathers essays inspired by conversations with cabbies, ranging over the possible nature of alien societies, the inevitability of life, and links between environmentalism and space exploration.

"In this EK title Roush investigates a topic that has fascinated him since college -- the possibility and probability of life, intelligent or otherwise, in the universe. The book covers the history and science of our search for extraterrestrial life, and investigates what that search means for us as a species, as well as what the implications of finding life on other planets might mean for life on Earth. The book covers various iterations of SETI, or the search for extraterrestrial intelligence, both in listening for messages from space as well as sending them. Roush also covers more recent efforts to find exoplanets, worlds similar enough to our own to possibly harbor life in even very basic forms. Some of this research is driven by discoveries of 'extremophile' life here on Earth in places and conditions previously considered to be unconducive to life forms. Roush co-taught a course on this topic last year at MIT"--

Mathematics is as much a part of our humanity as music and art. And it is our mathematics that might be understandable, even familiar, to a distant race and might provide the basis for mutual communication. This book discusses, in a conversational way, the role of mathematics in the search for extraterrestrial intelligence. The author explores the science behind that search, its history, and the many questions associated with it, including those regarding the nature of language and the philosophical/psychological motivation behind this search.

Although we have done extensive studies of the Solar System and thus far found over 300 extrasolar planets – planets outside our Solar System – we have not yet found life, even primitive life, on any planet other than Earth. Might there be life on some of these newly discovered extrasolar planets? Not likely, as most are gas giants or are too close or too far from their sun. However, of late we are finding more and more Earthlike planets. It is now estimated that about 15 percent of the planets in the galaxy are Earthlike, and many of these will likely orbit their suns at the right distance to support life as we know it. No one knows yet if radio searches or other means of detection will reveal that we are not alone in the universe. But if we do discover intelligent life elsewhere, how will we communicate with it? Are there some “universal” methods of communication we can use? Is music or mathematics a universal language? Are there alien intelligences right here on Earth we can use to help us figure out ways of communicating? The answers may surprise you. All of these issues and more are covered in this exciting, readable, and authoritative book on a subject that is not mere idle speculation anymore. We are certainly getting closer to finding out who, if anybody, is out there. This book will not only inform you about the search and the likelihood of finding life, it will also actually teach you how to talk to aliens!

Astronomer Peter Linde takes the reader through the story of the search for extraterrestrial life in a captivating and thought-provoking way, specifically addressing the new research that is currently devoted towards discovering other planets with life. He discusses the methods used to detect possible signals from other civilizations and the ways that the space sciences are changing as a result of this new field. “Are we alone?” is a mystery that has forever fascinated mankind, gaining momentum by scientists since the 1995 discovery of the existence of exoplanets began to inspire new ways of thinking in astronomy. Here, Linde tries to answer many philosophical questions that derive from this area of research: Is humanity facing a change of paradigm, that we are not unique as intelligent beings? Is it possible to communicate with others out there, and even if we can—should we?
