When: May 14 - 18, 2018
Where: Earth Life Science Institute, Tokyo Institute of Technology, Tokyo, Japan
What: For decades (if not centuries) scientific researchers have wondered about the existence of extra-terrestrial life. Due to recent technological advances we now know that the Milky Way galaxy is filled to the brim with planets of all shapes and sizes, opening up the prospect of other galaxies hosting similar worlds.
The field of Astrobiology is an umbrella term that combines scientific expertise from astrophys-ics, planetary and Earth science, chemistry, biology and other scientific disciplines to under-stand how habitable worlds form and evolve with time. Yet the nature of the formation and evolution of these worlds and their proclivity to support a (long-term) biosphere remains ob-scure. It makes sense at this time to synthesise what we know, highlight key points of agreement and contention, and to provide recommendations for scientific progress.
Focus: Our goal is to host a small meeting of thirty to thirty-five people of broad scope with key speakers of international standing. We aim to unite ourselves to discuss barriers to progress, propose solutions and identify and foster future collaboration that will advance the field as a whole. We intend to formulate a coherent pathway towards the necessary conditions that nur-tures extra-terrestrial life on billion-year timescales.
Structure: The meeting will last four and a half days and will be a mélange of presentations and discussions. All days will consist of contributed presentations from invited members showing the current state-of-the-art in their fields, and possible summary presentations at the end. The final session before dinner comprises an open forum for discussion and voluntary contribution of new ideas and/or results that encourage understanding and future collaboration.
