Astrobiology and Solar System Exploration

     How does life begin and evolve? Does life exist elsewhere in the Universe? How do planetary systems form? What makes a planet habitable?

     This workshop will be dedicated to the presentation of the latest results from ongoing space missions to Mars, Saturn, and Titan. We also invite contributions related to future exploratory programs and missions in the solar system, planetary protection, the formation and detection of rocky (exo)planets, the origin and early evolution of life on Earth, life in Earth extreme environments potentially analogous to extraterrestrial habitats, and the characterization of biosignatures for the detection of life in our solar system and beyond.

Extension: Astrobiology in Belgium, July 8th, 2005

     Astrobiology is the study of life's origin, evolution and distribution in the Universe. It is thus interdisciplinary, gathering researchers from astronomy, biology, chemistry, engineering, geology, physics and even law and philosophy. Several national Astrobiology groups/centres have been established within the EU (e.g. in France, Poland, Spain, Sweden and the United Kingdom), and are coordinated since 1999 by the European Astrobiology Network Association (EANA). Belgium is also a member of EANA but is represented by only a few people. The objective of this one-day workshop is to group Belgian researchers interested by astrobiology, and to encourage multidisciplinary and national collaborations in research, teaching and outreach related to astrobiology. The workshop will consist in short scientific presentations (made accessible to scientists of all disciplines) and a round-table discussion about the development of Astrobiology in Belgium. We invite contributions by Belgian scientists on all topics related to astrobiology.

Registration (free) to July 8th workshop "Astrobiology in Belgium" only.
