Our neighboring planets may have the answer to this question. Scientists have already identified ice caps on Mars and what appear to be enormous oceans underneath the ice of Jupiter's moons. The atmosphere on Venus appeared harsh and insupportable of life, composed of a toxic atmosphere and oceans of acid -- until scientists concluded that Earth's atmosphere was eerily similar billions of years ago. An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities, showing the emotions, the controversy, and the egos involved in arguably the most important scientific pursuit ever begun.

This book describes a wide variety of speculations by many authors about the consequences for humanity of coming into contact with extraterrestrial intelligence. The assumptions underlying those speculations are examined, and some conclusions are drawn. The book emphasizes the consequences of contact rather than the search, and takes account of popular views. As necessary background, the book also includes brief summaries of the history of thinking about extraterrestrial intelligence, searches for life and for signals, contrasting paradigms of how contact might take place, and the paradox that those paradigms allegedly create.

Interest in exoplanets--the worlds of other stars--is not new. From the late 17th century until the end of the 19th, almost all educated people believed that the stars are suns surrounded by inhabited planets--a belief that was expressed not in science fiction, but in serious speculation, both scientific and religious, as well as in poetry. Only during the first half of the 20th century was it thought that life-bearing exoplanets are rare. This is not a science book--rather, it belongs to the category known as History of Ideas. First published by Atheneum in 1974, it tells the story of the rise, fall, and eventual renewal of widespread conviction that we are not alone in the universe. In this 2012 updated edition the chapters dealing with modern speculation have been revised to reflect the progress science has made during the past 40 years, including the actual detection of planets orbiting other stars. However, it is not intended to be more than a brief introduction to today's views; its focus is on little-known facts about those of the past. Why should we care what our forebears believed? Now, the question of ET life is a matter for investigation by science. Yet it's significant that most educated people of past centuries were convinced that other inhabited worlds exist, without any scientific evidence whatsoever. This historical fact reveals that human beings have an instinctive sense of kinship with the wider universe and a desire to see the realms that lie beyond this one small planet--and perhaps, eventually, to go there. Our ancestors conceived of such voyages only in a spiritual sense, as occurring after death. But we who have taken our first small steps into space are aware that our descendants may set foot on the worlds of other suns. Just as in the 17th century people were initially upset by the new knowledge that the stars are suns scattered in space rather than lights fixed to a nearby sphere, the growing awareness that Earth is not safely isolated from whatever lies beyond makes many of our contemporaries uneasy. Thus today's predominant feelings about spaceships are ambivalent. Nevertheless, if an impulse toward belief that we are not alone in the universe is indeed an innate characteristic of human beings, as the past spread of belief in inhabited exoplanets suggests, we can be sure that those who follow us will not turn back from becoming spacefarers.

If we have learned anything from recent advances in cosmology and astronomy, it is that we have only barely begun to comprehend the vastness of our universe and all that it contains. For Christians, this raises some fascinating questions: If there are intelligent beings out there, what would be their relationship to what Christianity claims is a special history on Earth of life with God? Would the fact of persons on other planets banish or modify our understanding of God? Would it reduce the importance of Jesus? What role might goodness and evil play in extraterrestrial civilizations? Might God have incarnated himself among other races of creatures, as he became incarnate as Jesus among us? Respectful of the sciences that disclose the reality of the universe, Thomas O'Meara wonders about good and evil, intelligence and freedom, revelation and life as they might exist in other galaxies. In this book, one possible aspect of the universe we live in meets the perspective of Christian revelation.
