First Steps in the Origin of Life in the Universe

The Sixth Trieste Conference on Chemical Evolution for the first time has also been a Euroconference. This year we focused on First Steps in the Origin of Life in the Universe. (Both this Centre and the ICGEB have been sponsors since we first started planning the series with Professors Abdus Salam and Cyril Ponnamperuma. ) The conference had the following 11 sponsors: The Abdus Salam International Centre for Theoretical Physics, The European Commission, The SETI Institute, Consiglio Nazionale delle Ricerche, Rome, Italy, The International Centre for Genetic Engineering and Biotechnology, Trieste, The European Space Agency (ESA), National Aeronautics and Space Administration (NASA) Universite Paris 12, The ICTP Public Information Office, La Fondazione Internazionale Trieste per il Progresso e la Liberta della Scienza, and II Laboratorio dell'Immaginario Scientifico. of our Over 90 participants allowed us to make a truly comprehensive review subject. In 82 presentations we had contributions from experts in questions related to the origin, evolution, distribution and destiny of life in the universe, topics that are known together as the science ofastrobiology. The publication ofthese proceedings was largely due to a generous grant form the Consiglio Nazionale delle Ricerche, Rome, Italy. The general topic of the conference concerned the origin, evolution, distribution and destiny of life in the Universe, a subject referred to as astrobiology and also as exobiology. In this report we prefer the synonym Astrobiology.
