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. 2010, Gebunden, Neuware, 588g, 248, sofortueberweisung.de, PayPal, Banküberweisung.

The evolution of life on Earth during the last four billion years has not been uniform. Several distinct periods of mass extinction are known, the last led to the extinction of the dinosaurs some 60 million years ago. The causes for these mass extinctions are, at least in some cases, cosmic catastrophes, such as impacts of asteroid sized bodies, nearby supernova explosions etc. It is also well known that the last ice ages are triggered by variations of different parameters of the Earth'r orbit about the Sun. Cosmic catastrophes therefore have to be considered when evolution of life on planets are discussed, especially the question of habitability on them. In this book we first discuss habitability not only on planets (in the solar system as well in extrasolar planetary systems) but also on satellites of giant planets. Life needs some energy source which is provided either by the central star of a planetary system or by tidal forces exerted by a giant planet on a large satellite of it. On Earth it took about four billion years for intelligent life to evolve. Such a long time span (which is about 1/3 of the total age of the universe) requires rather stable conditions. We therefore investigate in detail how cosmic catastrophes may destroy life, and at the same time lead to the evolution of new species. Catastrophes therefore seem to be essential for evolution to higher lifeforms. With the recent advances of biology, the detection of extrasolar planetary systems, the great advancement of our knowledge about the chemical and physical processes that enable life, these questions can be answered in much more detail than several years ago. The reader is provided with an introduction into the various topics and for further details recent literature is cited. It will be also stressed that the evolution of life on Earth is not only connected with the existence of a stable long-lived star, the Sun, but also depends on conditions and distribution of mass in the planetary.

It will be also stressed that the evolution of life on Earth is not only connected with the existence of a stable long-lived star, the Sun, but also depends on conditions and distribution of mass in the planetary system (the existence of giant planets at a certain distance from the Sun), the existence of the Moon (which stabilizes the Earth's rotational axis), the location of the solar system in the galaxy and other factors. Primitive forms of life, however, may require less stringent environmental conditions as the detection of extremophiles has proven.
