Glad to see models evolving to incorporate more nuanced factors for potential habitability – atmospheric composition, stellar activity, planetary geology, etc.

What are some of the most surprising or counter-intuitive parameters these new models are highlighting as crucial for life? For example, could a planet be technically outside the traditional liquid water zone but still be habitable due to extreme greenhouse effects or significant tidal heating? And how do these models account for the possibility of life forms that are radically different from Earth-based biology, potentially thriving in conditions we'd consider hostile?
