2006 Annual Science Report

University of Washington Reporting  |  JUL 2005 – JUN 2006

Executive Summary

In this, our fifth (and final?) year, our group continues its Year 4 drive at full productivity. It was also the year of Stardust, the highly successful comet return mission with co-I Don Brownlee serving as Mission PI. As in past years, our NAI sponsored research at the University of Washington has concentrated on the following important astrobiological questions:

  1. What are the characteristics of planets that can evolve complex organisms?
  2. Where might such planets occur?
  3. How does biological complexity evolve on a planet, and how might it end?
  4. What are the limits and permissible chemistries of life and how might they arise?

During the 2005-2006 period significant progress into these problems was made. Below, our results and progress is summarized based on specific research problems defined in our original proposal.

How often, where, and under which conditions do habitable planets form and persist?

Assessing the ...
