Spring 2021 Seminal Papers in Astrobiology schedule is now finalized! Guests, we welcome you to sit in on the presentations and discussions. Because this is a course with participation points given for students taking it for a grade, guests are asked to please reserve questions/comments until the end of the discussion period. Course meetings are Wednesdays 9:30-11:25 am Eastern on Blue Jeans: https://gatech.bluejeans.com/891027890
Please join us in congratulating EAS PhD Candidate Pengxiao Xu, 2021 recipient of a GT Astrobiology Graduate Certificate !

You are invited to participate in the Inaugural Prebiotic Chemistry and Early Earth Environments (PCE3) Community Workshop, which is intended to form bridges between disparate fields of astrobiology.
Registration is free and required to attend. You will receive an email with log-in after being approved. There is no cost to register. Register here: http://prebioticchem.org/workshop/workshop.html
The workshop is designed to cross-pollinate between different areas of research addressing origins of life, including early earth geoscience and prebiotic chemistry. This workshop will foster intellectual cooperation and innovation across the community and thereby give rise to novel research avenues. A central goal is to root models for the emergence of prebiotic pathways in realistic planetary conditions and fully integrate the dynamics and constraints of early Earth environments into origins hypotheses. Beyond our planet, PCE3 aims to identify planetary conditions that can or cannot give rise to life’s chemistry, thus guiding future missions that target the discovery of habitable worlds.
Please read this new Nature Astronomy paper to prepare for the discussion.
Recipe for a Habitable Planet
The discovery of numerous small exoplanets has brought the search for life beyond the Solar System into sharp focus on many potentially habitable worlds where life may exist. However, many factors
and processes can affect planetary climate and habitability, most of which are currently unconstrained by observations, and their effects must be understood to accurately determine a planet’s habitability potential and prioritize planets for observational follow-up. Professor Shields will describe the methods used by her research group to quantify the effects on planetary climate of a range of factors important for planetary habitability, and share recent results from this work, which demonstrates how the unique interactions between a star and a planet’s atmosphere and surface can produce either a recipe of successful ingredients for habitable surface conditions, or one that reveals less favorable planetary prospects for life.
