In the last 15 years we have made progress in understanding the origin and fate of life and the universe. Within the new standard cosmological model, constraints on the formation of terrestrial planets and life can be quantified. For example, we are beginning to be able to answer the questions: When did terrestrial planets first appear in the universe? How common are they? What are the dispersions in the abundances of the most important ingredients of terrestrial planets and life, as a function of time. These quantifications involve connections between cosmology, stellar evolution, the chemical enrichment of the universe, comparative planetology, geology and biochemistry and form the basis of new astrobiological efforts to determine how we fit into the universe.
