Creation of Molecules in the Interstellar Medium,obtained from meteorites that have come to Earth, as well as the anticipated further information at it is hoped will be obtained from future from space missions to comets. Finally, the Drake equation, which characterizes the possibility that we will receive signals from another civilization, is discussed.

How Have Scientists Explained the Amino Acid Chirality?, case, the experimental documentation for the hypothetical model is presented. The chapter then discusses amplification mechanisms, notably, autocatalysis, which could operate either in outer space or on Earth. Finally, experiments that have demonstrated amplification toward homochirality are discussed.

Book 2012w explanation that involves cosmic processing of the amino acids produced in space. The book provides a tour for laypersons that includes a definition of life, the Big Bang, stellar nucleosynthesis, the electromagnetic spectrum, molecules, and supernovae and the particles they produce.

1614-659X l by which their handedness could have been produced.RelatesWhere were the amino acids, the molecules of life, created: perhaps in a lightning storm in the early Earth, or perhaps elsewhere in the cosmos? This book argues that at least some of them must have been produced in the cosmos, and that the

Amino Acids and Chirality,near and circular polarization of light, again for non-experts. This leads to the discussion of the Buckingham effect (Chem Phys Lett 398:1, 2004; Chem Phys 324:111, 2006), by which one can discriminate between left- and right-handed amino acids given the right conditions. A short description of qu

How Have Scientists Explained the Amino Acid Chirality?,y polarized light could create chiral amino acids, both on Earth and in outer space, are detailed. Next, several models that rely on the weak interaction to select chirality are described. And, finally, the possibility that chiral selection might have occurred on solid surfaces is mentioned. In each
