• Planetary habitabilityRelated: Extremophiles show that terrestrial life tolerates conditions once thought to exclude habitability.

• ArchaeaNarrower topic: Some archaea tolerate heat, salinity, acidity, or pressure, though many live in ordinary habitats.

• Dead SeaRelated: Salt-adapted microbes thrive where most organisms cannot survive.

• PanspermiaRelated: Its resilience helps define which environmental stresses a traveling microbe might endure.
