Report

The International Astronomical Union's Commission 51 was established in 1982 as ``Bioastronomy: Search for Extraterrestrial Life''. As the interests of Commission members expanded to include all aspects of the study of the origin, evolution, and distribution of life in the universe, C51 was renamed simply ``Bioastronomy'' in 2006. Thus, the term ``bioastronomy'' became for the Commission essentially synonymous with the NASA-coined term ``astrobiology``. Since the latter term has been adopted by many scientific societies around the world with similar interests, under the new Division and Commission structure of the IAU the Commission has been again renamed and is now Commission F-3 ``Astrobiology''.
