Welcome to the Planetary Systems Biochemistry database

While we know at least one example of planetary life, our own biosphere, we currently have no predictive theories to guide our search for others. To move from an era of speculation about what life could be, to an era of predictions about what life is and where it is, we need new quantitative tools. Life in one environment may differ from life in another. Understanding how planetary processes couple to signatures of life, universally - not just here on Earth - is critical to developing these tools. This motivates our team to address the compelling focus question: What detectable universal patterns distinguish living chemistries through various stages of planetary evolution?
