Habitability and Cosmic Catastrophes: Advances in Astrobiology and Biogeophysics

Autor Arnold Hanslmeier
en Limba Engleză Paperback – 22 oct 2010
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.

Recenzii

From the reviews:
"Habitability and Cosmic Catastrophes, part of the ‘Advances in Astrobiology and Biogeophysics’ series, is an interesting read. Hanslmeier … provides information that spans numerous disciplines, from solar and galactic astrophysics and geology to biology. The book’s reach is tremendous: attempting to assess the risk to life from various cosmic catastrophes that range from supernovae to asteroid collisions and almost everything in between. … Summing Up: Recommended. Upper-division undergraduates through professionals/practitioners." (E. S. Perlman, Choice, Vol. 46 (11), 2009)

Textul de pe ultima copertă

The solar system has a rather well-known history. Looking at the present situation, one might get the impression that it was a rather stable and well-defined system: the orbits of the planets appear to be stable, climate and atmospheres on the planets have been determined, the risk of collision with other bodies (comets, asteroids, meteorites) seems to be small. However it is known today that the evolution of life on Earth was neither a steady progression nor uniform. There were several periods of mass extinction. These catastrophic events played a crucial role in the rise of new species. Events of astrophysical origin include:
• Asteroid impacts
• Major solar variabilty (space weather)
• Nearby supernovae
• The passage of the solar system through dense interstellar clouds
Catastrophic cosmic events of this type appear in the range of some 100 million years. The author discusses whether and how such events could have occurred in the solar system as well as in recently found extrasolar planetary systems.
In this text, which addresses readers in the field of Astrophysics and Astrobiology but also Geophysics and Biology these cosmic catastrophic events are described at an intermediate student's level.
