A rigorous and scientific analysis of the myriad possibilities of life beyond our planet.

“Are we alone in the universe?” This tantalizing question has captivated humanity over millennia, but seldom has it been approached rigorously. Today the search for signatures of extraterrestrial life and intelligence has become a rapidly advancing scientific endeavor. Missions to Mars, Europa, and Titan seek evidence of life. Laboratory experiments have made great strides in creating synthetic life, deepening our understanding of conditions that give rise to living entities. And on the horizon are sophisticated telescopes to detect and characterize exoplanets most likely to harbor life.

Life in the Cosmos offers a thorough overview of the burgeoning field of astrobiology, including the salient methods and paradigms involved in the search for extraterrestrial life and intelligence. Manasvi Lingam and Avi Loeb tackle three areas of interest in hunting for life “out there”: first, the pathways by which life originates and evolves; second, planetary and stellar factors that affect the habitability of worlds, with an eye on the biomarkers that may reveal the presence of microbial life; and finally, the detection of technological signals that could be indicative of intelligence. Drawing on empirical data from observations and experiments, as well as the latest theoretical and computational developments, the authors make a compelling scientific case for the search for life beyond what we can currently see.

Meticulous and comprehensive, Life in the Cosmos is a master class from top researchers in astrobiology, suggesting that the answer to our age-old question is closer than ever before.

"The search for intelligent alien life continues to motivate and inspire generations of scientists and the public alike…The authors separate themselves from other treatments of similar topics by focusing on ‘extraterrestrial technological intelligences’ rather than alien life more generally." - Nature Astronomy

"Boldly goes where few academic books have gone before by seriously and open-mindedly considering the possibility of extraterrestrial technological intelligence on par with or far beyond humans…Chock-full of interesting topics and insights…A stellar achievement that deserves the undivided attention of readers who are ready to take a deep dive into astrobiology." - Inquisitive Biologist

"An excellent primer on life on earth, from the very beginnings…Both incredibly wide-ranging and constantly fascinating." - Complete Review
