Fate of Planetary Habitability highlighted at the AGU Fall Meeting

Leave a comment

Together with Cynthia Phillips, one of my SETI Institute colleagues, I will convene a session at the AGU Fall meeting tomorrow afternoon (oral) and Friday December 13 (poster) entitled “Rapid Environmental Change and the Fate of Planetary Habitability“.

This session will be an opportunity to see recent works on the adaptability of life in abrupt climate crises. Recent discoveries inspire us to re-examine our understanding of how rapidly planetary habitats can be redistributed. Past habitable environments on Mars from the Curiosity rover, possible subsurface lakes on Europa, and potentially habitable exoplanets from the Kepler spacecraft continue to expand our definition of the habitable zone.

slide_frontThe submitted abstracts intertwined aspects of changing habitability, including the complex interactions among astronomical, geological, and climatic forces, on the Earth and beyond.

Below the complete schedule which includes eight talks and four posters.

See you tomorrow at 1:40pm, room 2007 in Moscone West if you want to hear about habitability in our solar system and elsewhere.

About Franck Marchis

Dr. Franck Marchis is a Senior Researcher and Chair of the Exoplanet Group at the Carl Sagan Center of the SETI Institute since July 2007. Over the past 19 years, he has dedicated his research to the study of our solar system, specifically the search for asteroids with moons, using mainly ground-based telescopes equipped with adaptive optics. More recently he has been also involved in the definition of new generation of AOs for 8 -10 m class telescopes and future Extremely Large Telescopes. He has developed algorithms to process and enhance the quality of images, both astronomical and biological. His currently involved in the Gemini Planet Imager Exoplanet Survey, which consists in imaging exoplanets using an extreme AO system for the Gemini South telescope. This new instrument is be capable of imaging and recording spectra of young Jupiter-like exoplanets orbiting around nearby stars.
