Astrobiology
Monica M. Grady

Grady (head of petrology and meteoritics at The Natural History Museum) provides a general reader's introduction to a relatively old area of inquiry—whether and where there is life elsewhere in the universe. Using dozens of large color photos and diagrams, she describes how life evolved on Earth, the likeliness of life in other parts of the solar system, the search for Earth-like planets, and SETI.
