Micrometeorites and the Mysteries of Our Origins

Micrometeorites and the Mysteries of Our Origins by Michel Maurette
English | PDF (True) | 2006 | 333 Pages | ISBN : 3540258167 | 23.7 MB

Micrometeorites played an essential role in the formation of the atmosphere of the Early Earth and also served as a significant source of activation for organic prebiotic chemistry on mineral surfaces. The present book gives a coherent account of this scenario, embedding the more specific results within a broader framework that considers the creation and evolution of the Early Earth. It thus addresses students and nonspecialist researchers in the fields of planetary atmospheres, biogeophysics and astrobiology. The experienced researcher will find this volume to be a modern and compact reference, as well as a source of material for lectures in this field.

Life in the Universe: Expectations and Constraints

Life in the Universe: Expectations and Constraints by Dirk Schulze-Makuch, Louis N. Irwin
English | PDF(True) | 2008 | 260 Pages | ISBN : 3540768165 | 7.6 MB

Energy, chemistry, solvents, and habitats – the basic elements of living systems - define the opportunities and limitations for life on other worlds. This class-tested text examines each of these parameters in crucial depth and makes the argument that life forms we would recognize may be more common in our solar system than many assume. It also considers, however, exotic forms of life that would not have to rely on carbon as basic chemical element, solar energy as a main energy source, or water as primary solvent. Finally the question of detecting bio- and geosignature of such life forms is discussed, ranging from Earth environments to deep space.

Water in the Universe (Repost)

Water in the Universe by Arnold Hanslmeier
English | PDF,EPUB | 2011 | 249 Pages | ISBN : 9048199832 | 16.35 MB

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.
