Sind wir allein im Universum? Auf diese Frage geben der Geologe Peter D. Ward und der Astrobiologe Donald Brownlee überraschende Antworten. Sie widersprechen der allgemeinen Annahme, dass höher entwickeltes Leben außerhalb der Erde existiert, vielleicht sogar weit verbreitet ist. Auf der Suche nach Leben im Universum nehmen sie den Leser mit auf eine spannende Reise von den heißen vulkanischen Quellen des Ozeanbodens bis zu dem frostigen Antlitz von Europa, dem Jupiter-Mond. Dabei lernt der Leser, dass niedrig entwickeltes Leben vielleicht weiter verbreitet ist, als bisher angenommen, die Entstehung höher entwickelten Lebens aber zu komplex ist, um außerhalb der Erde stattfinden zu können. Ein faszinierendes, erfrischend geschriebenes Buch, das auf dem neuesten Stand der Wissenschaft beruht.

What determines whether complex life will arise on a planet, or even any life at all? Questions such as these are investigated in this groundbreaking book. In doing so, the authors synthesize information from astronomy, biology, and paleontology, and apply it to what we know about the rise of life on Earth and to what could possibly happen elsewhere in the universe. Everyone who has been thrilled by the recent discoveries of extrasolar planets and the indications of life on Mars and the Jovian moon Europa will be fascinated by Rare Earth, and its implications for those who look to the heavens for companionship.

Seit wenigen Jahren haben wir den Beweis: Es gibt sie, fremde Welten, auf denen ideale Bedingungen für die Entstehung von Leben herrschen. Dank der Erkenntnisse moderner Astrophysik erhöht sich die Wahrscheinlichkeit täglich, dass wir dieses Leben irgendwo dort draußen aufspüren. Florian Freistetter schildert, wie die moderne Astronomie erst lernen musste, das Unsichtbare zu sehen, um Supererden und Heiße Jupiter zu finden. Wie die fremden Welten beschaffen sein müssen, damit auf ihnen Leben entstanden sein kann – und wie wir mit Hilfe neuer Teleskope bald herausbekommen, wie Außerirdische wirklich aussehen. "Die Neuentdeckung des Himmels" ist die Chronik eines der größten Abenteuer der Menschheit: der Suche nach einer Antwort auf die Frage "Sind wir allein im Universum?".

Das neueste Wissen über die Entwicklung des Lebens auf der Erde Eine neue Geschichte des Lebens vereint erstmals die erst in den letzten Jahrzehnten gewonnenen Erkenntnisse verschiedener Fächer von der Geologie über Paläontologie, Geo- und Astrobiologie, Physik, Chemie bis zur Genetik, Zoologie und Botanik in einer großen, umfassenden Erzählung – und schreibt in entscheidenden Punkten die bisherige Darstellung der Evolution des Lebendigen auf der Erde um. Nach Darwin waren wir davon ausgegangen, dass sich die Veränderungen eher gleichförmig und allmählich vollzogen, aber der jetzt mögliche Blick in die Erdgeschichte zeigt, dass die Entwicklung stärker durch Katastrophen geprägt wurde und zwar nicht nur solche, die Meteoriteneinschläge von außen verursachten. Peter Ward und Joe Kirschvink schildern das spannende Zusammenspiel von Lebewesen und Ökosystemen, von Atmosphäre und Klima, das mehrmals im Lauf der Evolution dazu führte, dass sich die Bedingungen auf der Erde gravierend veränderten und Lebensformen massenhaft ausstarben. Sie geben einen faszinierenden Einblick in die seit 4,6 Milliarden Jahren dauernde Geschichte des Lebens und zeigen zugleich, wie fragil unsere heutige Lebenswelt ist.

In The Medea Hypothesis, renowned paleontologist Peter Ward proposes a revolutionary and provocative vision of life's relationship with the Earth's biosphere--one that has frightening implications for our future, yet also offers hope. Using the latest discoveries from the geological record, he argues that life might be its own worst enemy. This stands in stark contrast to James Lovelock's Gaia hypothesis--the idea that life sustains habitable conditions on Earth. In answer to Gaia, which draws on the idea of the "good mother" who nurtures life, Ward invokes Medea, the mythical mother who killed her own children. Could life by its very nature threaten its own existence? According to the Medea hypothesis, it does. Ward demonstrates that all but one of the mass extinctions that have struck Earth were caused by life itself. He looks at our planet's history in a new way, revealing an Earth that is witnessing an alarming decline of diversity and biomass--a decline brought on by life's own "biocidal" tendencies. And the Medea hypothesis applies not just to our planet--its dire prognosis extends to all potential life in the universe. Yet life on Earth doesn't have to be lethal. Ward shows why, but warns that our time is running out. Breathtaking in scope, The Medea Hypothesis is certain to arouse fierce debate and radically transform our worldview. It serves as an urgent challenge to all of us to think in new ways if we hope to save ourselves from ourselves.

The history of life on Earth is, in some form or another, known to us all--or so we think. A New History of Life offers a provocative new account, based on the latest scientific research, of how life on our planet evolved--the first major new synthesis for general readers in two decades. Charles Darwin's theories, first published more than 150 years ago, form the backbone of how we understand the history of the Earth. In reality, the currently accepted history of life on Earth is so flawed, so out of date, that it's past time we need a 'New History of Life.' In their latest book, Joe Kirschvink and Peter Ward will show that many of our most cherished beliefs about the evolution of life are wrong. Gathering and analyzing years of discoveries and research not yet widely known to the public, A New History of Life proposes a different origin of species than the one Darwin proposed, one which includes eight-foot-long centipedes, a frozen “snowball Earth”, and the seeds for life originating on Mars. Drawing on their years of experience in paleontology, biology, chemistry, and astrobiology, experts Ward and Kirschvink paint a picture of the origins life on Earth that are at once too fabulous to imagine and too familiar to dismiss--and looking forward, A New History of Life brilliantly assembles insights from some of the latest scientific research to understand how life on Earth can and might evolve far into the future.

This book explains how it came to be that Venus and Earth, while very similar in chemical composition, zonation, size and heliocentric distance from the Sun, are very different in surface environmental conditions. It is argued here that these differences can be accounted for by planetoid capture processes and the subsequent evolution of the planet-satellite system. Venus captured a one-half moon-mass planetoid early in its history in the retrograde direction and underwent its “fatal attraction scenario” with its satellite (Adonis). Earth, on the other hand, captured a moon-mass planetoid (Luna) early in its history in prograde orbit and underwent a benign estrangement scenario with its captured satellite.

By looking backward at the course of great extinctions, a paleontologist sees what the future holds. More than 200 million years ago, a cataclysmic event known as the Permian extinction destroyed more than 90 percent of all species and nearly 97 percent of all living things. Its origins have long been a puzzle for paleontologists. During the 1990s and the early part of this century, a great battle was fought between those who thought that death had come from above and those who thought something more complicated was at work. Paleontologist Peter. D. Ward, fresh from helping prove that an asteroid had killed the dinosaurs, turned to the Permian problem, and he has come to a stunning conclusion. In his investigations of the fates of several groups of mollusks during that extinction and others, he discovered that the near-total devastation at the end of the Permian period was caused by rising levels of carbon dioxide leading to climate change. But it's not the heat (nor the humidity) that's directly responsible for the extinctions, and the story of the discovery of what is responsible makes for a fascinating, globe-spanning adventure. In Under a Green Sky, Ward explains how the Permian extinction as well as four others happened, and describes the freakish oceans—belching poisonous gas—and sky—slightly green and always hazy—that would have attended them. Those ancient upheavals demonstrate that the threat of climate change cannot be ignored, lest the world's life today—ourselves included—face the same dire fate that has overwhelmed our planet several times before.

Cardinal Christoph Schnborns article on evolution and creation in The New York Times launched an international controversy. Critics charged him with biblical literalism and creationism. In this book, Cardinal Schnborn responds to his critics by tackling the hard questions with a carefully-reasoned the "theology of creation." Can we still speak intelligently of the world as creation and affirm the existence of the Creator, or is God a delusion? How should an informed believer read Genesis? If God exists, why is there so much injustice and suffering? Are human beings a part of nature or elevated above it? What is man's destiny? Is everything a matter of chance or can we discern purpose in human existence? In his treatment of evolution, Cardinal Schnborn distinguishes the biological theory from evolutionism, the ideology that tries to reduce all of reality to mindless, meaningless processes. He argues that science and a rationally-grounded faith are not at odds and that what many people represent as science is really a set of philosophical positions that will not withstand critical scrutiny. Purpose or Chance? directly raises the philosophical and theological issues many scientists today overlook or ignore. The result is a vigorous, frank dialogue that acknowledges the respective insights of the philosopher, the theologian and the scientist, but which calls on them to listen and to learn from each another.

Where do the unrighteous go after death? What is the plight of the guilty after the Day of Judgment? Are places like heaven, hell, and the lake of fire physical locations in the universe? Biblically based and scientifically reasoned answers to these questions, and more, lead to locating the planet Venus as one possible place for perdition. The book Venus: Don't Go There-What Science and Religion Reveal about Life after Death reviews past and present discoveries and provides future evidence for alliance between the physical sciences and the Bible. God ordained the sciences and religion to work together for the common good and to lead toward a comprehensive understanding of the future. Correlation between the Holy Scriptures and the sciences can work together to provide reasonable and meaningful truths. Through interdisciplinary study, the author deduces the ultimate destiny for unsaved humanity could be within the solar system, while providing a unique perspective to life after death.

Over the course of the twentieth century, scientists came to accept four counterintuitive yet fundamental facts about the Earth: deep time, continental drift, meteorite impact, and global warming. When first suggested, each proposition violated scientific orthodoxy and was quickly denounced as scientific—and sometimes religious—heresy. Nevertheless, after decades of rejection, scientists came to accept each theory. The stories behind these four discoveries reflect more than the fascinating push and pull of scientific work. They reveal the provocative nature of science and how it raises profound and sometimes uncomfortable truths as it advances. For example, counter to common sense, the Earth and the solar system are older than all of human existence; the interactions among the moving plates and the continents they carry account for nearly all of the Earth's surface features; and nearly every important feature of our solar system results from the chance collision of objects in space. Most surprising of all, we humans have altered the climate of an entire planet and now threaten the future of civilization. This absorbing scientific history is the only book to describe the evolution of these four ideas from heresy to truth, showing how science works in practice and how it inevitably corrects the mistakes of its practitioners. Scientists can be wrong, but they do not stay wrong. In the process, astonishing ideas are born, tested, and over time take root.

Evolution and the Emergent Self is an eloquent and evocative new synthesis that explores how the human species emerged from the cosmic dust. Lucidly presenting ideas about the rise of complexity in our genetic, neuronal, ecological, and ultimately cosmological settings, the author takes readers on a provocative tour of modern science's quest to understand our place in nature and in our universe. Readers fascinated with "Big History" and drawn to examine big ideas will be challenged and enthralled by Raymond L. Neubauer's ambitious narrative. How did humans emerge from the cosmos and the pre-biotic Earth, and what mechanisms of biological, chemical, and physical sciences drove this increasingly complex process? Neubauer presents a view of nature that describes the rising complexity of life in terms of increasing information content, first in genes and then in brains. The evolution of the nervous system expanded the capacity of organisms to store information, making learning possible. In key chapters, the author portrays four species with high brain:body ratios—chimpanzees, elephants, ravens, and dolphins—showing how each species shares with humans the capacity for complex communication, elaborate social relationships, flexible behavior, tool use, and powers of abstraction. A large brain can have a hierarchical arrangement of circuits that facilitates higher levels of abstraction. Neubauer describes this constellation of qualities as an emergent self, arguing that self-awareness is nascent in several species besides humans and that potential human characteristics are embedded in the evolutionary process and have emerged repeatedly in a variety of lineages on our planet. He ultimately demonstrates that human culture is not a unique offshoot of a language-specialized primate, but an analogue of fundamental mechanisms that organisms have used since the beginning of life on Earth to gather and process information in order to buffer themselves from fluctuations in the environment. Neubauer also views these developments in a cosmic setting, detailing open thermodynamic systems that grow more complex as the energy flowing through them increases. Similar processes of increasing complexity can be found in the "self-organizing" structures of both living and nonliving forms. Recent evidence from astronomy indicates that planet formation may be nearly as frequent as star formation. Since life makes use of the elements commonly seeded into space by burning and expiring stars, it is reasonable to speculate that the evolution of life and intelligence that happened on our planet may be found across the universe.

Is it Reasonable to Believe? Remarkably, even though millions upon millions of us do believe in God, when we are asked why we have such faith, we become tongue-tied and struggle to give a reason for our hope. No wonder those who don't believe God exists remain unconvinced—there's too few of us ready to speak on God's behalf! Ken Boa and Robert Bowman have provided a resource that tackles the most profound arguments from philosophy, science, sociology, psychology, and history ... and presents twenty clear, concise, and compelling evidences that show that faith in God—and specifically Jesus Christ—is reasonable.
