Book Description
If we send a message into space, will extraterrestrial beings receive it? Will they understand? The endlessly fascinating question of whether we are alone in the universe has always been accompanied by another, more complicated one: if there is extraterrestrial life, how would we communicate with it? In this book, Daniel Oberhaus leads readers on a quest for extraterrestrial communication. Exploring Earthlings' various attempts to reach out to non-Earthlings over the centuries, he poses some not entirely answerable questions: If we send a message into space, will extraterrestrial beings receive it? Will they understand? What languages will they (and we) speak? Is there not only a universal grammar (as Noam Chomsky has posited), but also a grammar of the universe? Oberhaus describes, among other things, a late-nineteenth-century idea to communicate with Martians via Morse code and mirrors; the emergence in the twentieth century of SETI (the search for extraterrestrial intelligence), CETI (communication with extraterrestrial intelligence), and finally METI (messaging extraterrestrial intelligence); the one-way space voyage of Ella, an artificial intelligence agent that can play cards, tell fortunes, and recite poetry; and the launching of a theremin concert for aliens. He considers media used in attempts at extraterrestrial communication, from microwave systems to plaques on spacecrafts to formal logic, and discusses attempts to formulate a language for our message, including the Astraglossa and two generations of Lincos (lingua cosmica). The chosen medium for interstellar communication reveals much about the technological sophistication of the civilization that sends it, Oberhaus observes, but even more interesting is the information embedded in the message itself. In Extraterrestrial Languages, he considers how philosophy, linguistics, mathematics, science, and art have informed the design or limited the effectiveness of our interstellar messaging.

Book Description
Are alien civilizations really possible? If extraterrestrials exist, where are they? How likely is it that somewhere in the universe an Earth-like planet supports an advanced culture? Why do so many people claim to have encountered Aliens? In this gripping exploration, scientist Don Lincoln exposes and explains the truths about the belief in and the search for life on other planets. In the first half of Alien Universe, Lincoln looks to Western civilization's collective image of Aliens, showing how our perceptions of extraterrestrials have evolved over time. The roots of this belief can be traced as far back as our earliest recognition of other planets in the universe—the idea of them supporting life was a natural progression of thinking that has fascinated us ever since. Our captivation with Aliens has, however, led to mixed results. The world was fooled in the nineteenth century during the Great Moon Hoax of 1835, and many people misunderstood Orson Welles's 1938 radio broadcast, The War of the Worlds, leading to significant anxiety among some listeners. Our continuing interest in Aliens is reflected in entertainment successes such as E.T., The X-Files, and Star Trek. The second half of the book explores the scientific possibility of whether advanced Alien civilizations do exist. For many years, researchers have sought to answer Enrico Fermi’s great paradox—if there are so many planets in the universe and there is a high probability that many of those can support life, then why have we not actually encountered any Aliens? Lincoln describes how modern science teaches us what is possible and what is not in our search for extraterrestrial civilizations. Whether you are drawn to the psychological belief in Aliens, the history of our interest in life on other planets, or the scientific possibility of Alien existence, Alien Universe is sure to hold you spellbound.

Book Description
From this book, the reader will gain an insight into one of the most creative minds in the history of space exploration. Krafft Ehricke's contribution to space exploration encompasses details of new, innovative ideas, but also how to think about the importance and value of space exploration for society. The reader will gain an understanding of the early history of the space pioneers, what they have helped accomplish, and how Ehricke's vision of where we should be going can shape the future. At this time, when there are questions about the path of the space program for the next decades, Krafft Ehricke has laid out the philosophical framework for why space exploration must be pursued, through his concept of the "Extraterrestrial Imperative," and the fight that he waged, over many years, for a long-range vision for the program. Readers will find it a very imaginative work, and a very up-lifting story. Krafft Ehricke's Extraterrestrial Imperative is the summation of his work on encouraging the exploration and development of space. The book contains all of his reasons why we need to get off the planet and explore space.

Book Description
Unmasking the mysteries of alien life on earth! Make mention of the word “alien” and it conjures images of black-eyed, large-headed, dwarfish beings that have come to be known as the Greys. Indeed, Greys have become a staple part of pop-culture, never mind just the field of UFO research. They’ve appeared in Steven Spielberg’s classic 1977 movie, Close Encounters of the Third Kind. They regularly popped up in The X-Files. And, of course, there are numerous people – all across the world – who claim to have been abducted by the Greys and subjected to intrusive medical experiments. Yet, before the 1950s, the Greys were nowhere in sight. The Alien Book: A Guide to Extraterrestrial Beings on Earth shows that extraterrestrial life comes in all kinds, appearances, sizes, and bodies. They all have one thing in common, however: the human race has encountered them, and we continue to do so today. Not just dozens, or even hundreds, but thousands of eyewitness experiences have been reported. Covering hundreds of extraterrestrial life forms in more than 40 thematic chapters, this absorbing look at the mysteries of aliens on earth includes ... the Space Brothers: long-haired, very human-looking ETs the fiendish Reptilians: seven-to-eight-foot-tall predatory shapeshifters Men in Black beings: extremely pale-skinned, tall, and with huge eyes Black-eyed Children: anemic-looking kids with solid black eyes that might be ET-human hybrids Bigfoot the werewolf-like Dogmen jellyfish-style aliens that soar around the skies of our world the Shadow People: dangerous humanoids that terrorize people legendary Nephilim space-vampires: insect-like aliens that resemble a giant praying mantis and many, many more! The Alien Book investigates the full range of sentient, alien life forms. Some are benign and others downright deadly. Some are small, like a germ or virus that has NASA, creating guidelines to deal with an outbreak of an extraterrestrial germ. Some are big like a giant praying mantis or the biblical Goliath. They all lurk on Earth and in this chilling book! With more than 120 photos and graphics, this tome is richly illustrated. Its helpful bibliography and extensive index add to its usefulness.

Book Description
Witty and thought provoking, two Vatican astronomers shed provocative light on some of the strange places where religion and science meet. “Imagine if a Martian showed up, all big ears and big nose like a child’s drawing, and he asked to be baptized. How would you react?” —Pope Francis, May, 2014 Pope Francis posed that question—without insisting on an answer!—to provoke deeper reflection about inclusiveness and diversity in the Church. But it's not the first time that question has been asked. Brother Guy Consolmagno and Father Paul Mueller hear questions like that all the time. They’re scientists at the Vatican Observatory, the official astronomical research institute of the Catholic Church. In Would You Baptize an Extraterrestrial? they explore a variety of questions at the crossroads of faith and reason: How do you reconcile the The Big Bang with Genesis? Was the Star of Bethlehem just a pious religious story or an actual description of astronomical events? What really went down between Galileo and the Catholic Church—and why do the effects of that confrontation still reverberate to this day? Will the Universe come to an end? And… could you really baptize an extraterrestrial? With disarming humor, Brother Guy and Father Paul explore these questions and more over the course of six days of dialogue. Would You Baptize an Extraterrestrial will make you laugh, make you think, and make you reflect more deeply on science, faith, and the nature of the universe.

Book Description
"A cogent, engaging history of humanity's most ambitious quest--seeking outward for other minds."--David Brin, author of Existence "A fascinating perspective on humankind's obsession for knowing if there is anyone else out there."--Gerrit L. Verschuur, author of The Invisible Universe: The Story of Radio Astronomy "Squeri has written what will likely be the definitive history of the early days of SETI that includes profiles of some of its leading characters."--Ben Zuckerman, coeditor of Extraterrestrials: Where Are They? "An insightful history that explores the scientific foundations of the modern-day search for our place in the cosmos. Waiting for Contact delivers unparalleled access to the inner history of SETI and invites us to ride along on the journey to answer one of science's ultimate questions: Are we alone?"--Douglas Vakoch, president, METI International "Waiting for Contact is a balanced account, telling the tale of the search for extraterrestrial intelligence without the overpromise usually trumpeted by enthusiastic proponents and the hyperventilation so commonly added by UFO enthusiasts. If you are simply interested in the history, unvarnished by an agenda, you'll enjoy this book."--Don Lincoln, author of Alien Universe: Extraterrestrial Life in Our Minds and in the Cosmos Imagine a network of extraterrestrials in radio contact with each other across the universe, superior beings who hail from advanced civilizations quadrillions of miles away, just waiting for Earth to tune in. Some people believe it’s only a matter of time before we discover the right "station." Waiting for Contact tells the story of the Search for Extraterrestrial Intelligence (SETI) movement, which emerged in 1959 as astronomers began using radio telescopes to listen for messages from space. New technological developments turned what once was speculation into science. Boosted by support from Frank Drake, Philip Morrison, Carl Sagan, and the genre of science fiction, the SETI movement gained followers and continues to capture imaginations today. In this one-of-a-kind history, Lawrence Squeri looks at the people, reasons, goals, and mindsets behind SETI. He shows how it started as an expression of the times, a way out of Cold War angst with hope for a better world. SETI's early advocates thought that with guidance from technically and ethically advanced outsiders, humanity might learn how to avoid horrors like nuclear annihilation and societal collapse from overpopulation. Some hoped that good news from outer space might reveal a cure for cancer or even the secret of immortality. Squeri also describes the challenges SETI has faced over the years: the struggle to be taken seriously by the scientific community and by NASA, competition for access to radio telescopes, perpetual lack of funding, and opposition from influential politicians. He covers the rise and fall of Soviet SETI and the few rare meetings between Soviet and American astronomers. Despite many setbacks, the movement pressed forward with the aid of private donations and developed outreach programs. Volunteers can now help search for new civilizations on their personal computers by joining the SETI@Home project. Today, SETI researchers continue to see themselves as explorers. They often identify with Columbus, and just as Columbus never realized the full implications of his discovery, we cannot predict what will happen if contact is made. This book points out that if, against all expectations, the embattled SETI movement finally succeeds, the long-awaited first signal picked up by its radio antennas will usher the greatest shift in human history. A new adventure will begin. Lawrence Squeri is professor emeritus of history at East Stroudsburg University.
