P43G:
Climate and Habitability of Rocky Planets in the Solar System and Beyond I Posters


Submit an Abstract to this Session


Session ID#: 45719

Session Description:
Recent advances in understanding the early habitability of Mars and Venus, the imminent exploration of rocky exoplanets by the James Webb Space Telescope, and mission proposals to search for life in the outer Solar system motivate us to consider planetary habitability from a wide range of angles.

Questions of particular interest include: What does the solar system tell us about the habitability of exoplanets, and how can exoplanets inform our understanding of habitability? What drives Earth’s long-term climatic stability and how will it end? What planetary conditions affect the emergence and maintenance of life, such as long-term volatile cycling or the evolution of a planet’s host star? Finally, what insight can we glean from lifeless worlds about the conditions necessary for sustaining life?

We invite studies that use observations, experiments, and theory to expand our understanding of the climates and habitability of rocky planets in our Solar System and beyond.
