Overview
Advanced view of Extremophiles & Habitability
Extremophiles are organisms that thrive under conditions humans consider extreme, such as high temperature, acidity, salinity, pressure, cold, or radiation. They expand the range of known biological tolerances but do not imply that life can survive under arbitrary conditions.
Extremophile research informs planetary protection, Mars and ocean-world exploration, biosignature interpretation, and models of possible subsurface ecosystems.
