P31D:
The Physical Conditions Controlling Life's Origin, Evolution, and End I Posters


Session ID#: 7574

Session Description:
New insights into Mars’ wet past, the confirmation of a liquid ocean on Ganymede, and the ongoing stream of exoplanet discoveries raise the prospect of an ever-wider range of environments that could sustain life. This session explores how such environments emerge, are sustained, and eventually decline.

Questions of particular interest include: What is Earth’s long-term climatic stability and how will it end? How long did habitable conditions persist on Mars and did they ever exist on Venus? What habitable environments exist in the outer Solar System and how do they continue to evolve? How do the Faint Young Sun Problem, the Runaway Greenhouse, and long-term climate feedbacks play out across different planets and outside the Solar System?

We invite case studies and comparisons that use observations, experiments and/or modeling to expand our understanding of the habitability of diverse environments in our Solar System and beyond.
