This volume contains papers from the 9th International Bioastronomy
Conference in 2007, was organized around four broad themes: the origin of prebiotic material in space and delivery to the Earth; investigation of habitable worlds in the solar system and the building blocks of life; the origin of early life and its co-evolution with the environment; and extrasolar planets and biosignatures.
In early July, however, Michel Mayor of Geneva Observatory and his colleagues reported at a bioastronomy
meeting in Capri, Italy, that they had discovered or confirmed the existence of six brown dwarfs orbiting nearby stars and having masses between 16 and 40 times Jupiter's.
The journal's international editorial board includes 75 noted scientists from 16 countries whose expertise covers the fields of meteoritics, cosmochemistry, gravitational biology, planetary geology and habitability, exobiology, microbial paleobiology, ecogeology, origins of life, bioastronomy
, life detection and space exploration technology, microbial ecology, genomics, computational biology, and proteomics, among others.
