Where 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 fact that the Earthly amino acids have a specific handedness provides an important clue for that explanation. The book discusses several models that purport to explain the handedness, ultimately proposing a new 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. ### Review From the reviews: Book shows the reader first the beginning of atoms and molecules, and how they formed, and then continues with the intriguing question of chirality in molecules, and in amino acids in particular.  presented in an easily understandable way with several schematics and images to explain some of the concepts.  presents an interesting topic, that is certainly exciting and informative for the general reader, showing connections between various fields of research, and different astronomical objects and life on Earth. (Kadri Tinn, AstroMadness.com, April, 2014) Boyd  presents a summary of his work and that of his colleagues in which the left-handed symmetry is postulated to result from exposure of the amino acids to circularly polarized starlight during their formation in space.  the book serves as an in-depth introduction to the topic of the extraterrestrial origin of amino acids.  The text is very lucid and accessible to general readers  . Summing Up: Recommended. Lower-division undergraduates through graduate students; informed general readers. (A.
