The search for life in the universe is one of the most challenging topics of science. It is not a modern topic at all, since more than 100 years ago, it was speculated that on the Moon, there are oceans and seas; on Venus, there are swamps and also Mars is inhabitated. However, now we have the scienti?c background and the scienti?c tools to answer this question and it is also certain that the answer would have deep imp- cations for our culture, philosophy, and religions. If we ?nd that life has developed on other planets or satellites of giant planets, then this would be the ?nal breakdown of our central position in the universe. But is life a widespread phenomenon? How vulnerable is it to changing conditions and even catastrophic events? These topics will be discussed in this book. If life is in the extreme case a unique phenomenon found only on planet Earth, which seems to be highly unrealistic, then also it is important to discuss how it is adaptable to changing external conditions. Can we survive a cosmic catastrophe? How do these catastrophes change habitability? Which forms of life are more v- nerable? It was mentioned that now science has made great progress to answer such qu- tions. Let us give some examples. In modern biology, in connection with organic chemistry, the origin of life is studied.

A trio of editors [Professors from Austria, Germany and Israel] present Life on Earth and other Planetary Bodies. The contributors are from twenty various countries and present their research on life here as well as the possibility for extraterrestrial life. This volume covers concepts such as life’s origin, hypothesis of Panspermia and of life possibility in the Cosmos. The topic of extraterrestrial life is currently ‘hot’ and the object of several congresses and conferences. While the diversity of “normal” biota is well known, life on the edge of the extremophiles is more limited and less distributed. Other subjects discussed are Astrobiology with the frozen worlds of Mars, Europa and Titan where extant or extinct microbial life may exist in subsurface oceans; conditions on icy Mars with its saline, alkaline, and liquid water which has been recently discovered; chances of habitable Earth-like [or the terrestrial analogues] exoplanets; and SETI’s search for extraterrestrial Intelligence.

The Great Silence explores the multifaceted problem named after the great Italian physicist Enrico Fermi and his legendary 1950 lunchtime question "Where is everybody?" In many respects, Fermi's paradox is the richest and the most challenging problem for the entire field of astrobiology and the Search for ExtraTerrestrial Intelligence (SETI) studies. This book shows how Fermi's paradox is intricately connected with many fields of learning, technology, arts, and even everyday life. It aims to establish the strongest possible version of the problem, to dispel many related confusions, obfuscations, and prejudices, as well as to offer a novel point of entry to the many solutions proposed in existing literature. Milan Cirkovic argues that any evolutionary worldview cannot avoid resolving the Great Silence problem in one guise or another.

When it premiered on NBC in September 1966, Star Trek was described by its creator, Gene Roddenberry, as “Wagon Train to the stars.” Featuring a racially diverse cast, trips to exotic planets, and encounters with an array of alien beings who could be either friendly or hostile, the program opened up new vistas for television. Along with The Twilight Zone and The Outer Limits, Star Trek represented one of the small screen’s rare ventures into science fiction during the 1960s. Although the original series was a modest success during its three-year run, its afterlife has been nothing less than a cultural phenomenon. To celebrate the show’s debut fifty years later, it’s time to reexamine one of the most influential programs in history. In Gene Roddenberry’s Star Trek: The Original Cast Adventures, Douglas and Shea T. Brode present a collection of essays about the series and its various incarnations over the years. Contributors discuss not only the 1960s show but also its off-shoots, ranging from novels and graphic novels to toys and video games, as well as the films featuring Captain Kirk, Mr. Spock, and the rest of the Enterprise crew. Essays address the show’s religious implications, romantic elements, and its role in the globalization of American culture. Other essays draw parallels between the series and the Vietnam War, compare Star Trek II to Milton’s Paradise Lost, posit Roddenberry as an auteur, and consider William Shatner as a romantic object. With its far-reaching and provocative essays, this collection offers new insights into one of the most significant shows ever produced. Besides television and film studies, Gene Roddenberry’s Star Trek—a companion volume to The Star Trek Universe—will be of interest to scholars of religion, history, gender studies, queer studies, and popular culture, not to mention the show’s legions of fans.

th th Mars, the Red Planet, fourth planet from the Sun, forever linked with 19 and 20 Century fantasy of a bellicose, intelligent Martian civilization. The romance and excitement of that fiction remains today, even as technologically sophisticated - botic orbiters, landers, and rovers seek to unveil Mars’ secrets; but so far, they have yet to find evidence of life. The aura of excitement, though, is justified for another reason: Mars is a very special place. It is the only planetary surface in the Solar System where humans, once free from the bounds of Earth, might hope to establish habitable, self-sufficient colonies. Endowed with an insatiable drive, focused motivation, and a keen sense of - ploration and adventure, humans will undergo the extremes of physical hardship and danger to push the envelope, to do what has not yet been done. Because of their very nature, there is little doubt that humans will in fact conquer Mars. But even earth-bound extremes, such those experienced by the early polar explorers, may seem like a walk in the park compared to future experiences on Mars.

In The Earth as a Distant Planet, the authors become external observers of our solar system from a distance and try to determine how one can understand how Earth, the third in distance to the central star, is essentially unique and capable of sustaining life. The knowledge gained from this original perspective is then applied to the search for other planets outside the solar system, or exoplanets. Since the discovery in 1992 of the first exoplanet, the number of planet detections has increased exponentially and ambitious missions are already being planned for the future. The exploration of Earth and the rest of the rocky planets are Rosetta stones in classifying and understanding the multiplicity of planetary systems that exist in our galaxy. In time, statistics on the formation and evolution of exoplanets will be available and will provide vital information for solving some of the unanswered questions about the formation, as well as evolution of our own world and solar system. Special attention is paid to the biosignatures (signs of life) detectable in the Earth's reflected spectra and the search for life in the universe. The authors are experts on the subject of extrasolar planets. They provide an introductory but also very much up-to-date text, making this book suitable for researchers and for advanced students in astronomy and astrophysics.

Due to its specific chemical and physical properties, water is essential for life on Earth. And it is assumed that this would be the case for extraterrestrial life as well. Therefore it is important to investigate where water can be found in the Universe. Although there are places that are completely dry, places where the last rainfall happened probably several 100 million years ago, surprisingly this substance is quite omnipresent. In the outer solar system the large satellites of Jupiter and Saturn are covered by a thick layer of ice that could be hiding a liquid ocean below. This of course brings up the question of whether the recently detected extrasolar planets could have some water on their surfaces and how we can detect this. Water molecules are also found in interstellar gas and dust clouds. This book begins with an introductory chapter reviewing the physical and chemical properties of water. Then it illuminates the apparent connection between water and life. This is followed by chapters dealing with our current knowledge of water in the solar system, followed by a discussion concerning the potential presence and possible detection of water on exoplanets. The signature of water in interstellar space and stars are reviewed before the origin of water in the Universe is finally discussed. The book ends with an appendix on detection methods, satellite missions and astrophysical concepts touched upon in the main parts of the book. The search for water in the Universe is related to the search for extraterrestrial life and is of fundamental importance for astrophysics, astrobiology and other related topics. This book therefore addresses students and researchers in these fields.
