The Fate of Planetary Habitability - An AGU session by SETI Institute Researchers in the News
This session was an opportunity to see recent works on the adaptability of life in abrupt climate crises. Recent discoveries that inspire us to re-examine our understanding of how rapidly planetary habitats can be redistributed were discussed.
An article published in Space.com reports on one of the talks of this session. Jack Lissauer, researcher at NASA Ames, and his team conducted simulations which show that a large moon is not needed to stabilize the inclination of a planet. This work suggests that the presence of a large moon is not a necessary condition for an exoplanet to have a biosphere.
