The putative ocean of Europa has focused considerable attention on the potential habitats for life on Europa. By generally clement Earth standards, these Europan habitats are likely to be extreme environments. The objectives of this paper were to examine: (1) the limits for biological activity on Earth with respect to temperature, salinity, acidity, desiccation, radiation, pressure, and time; (2) potential habitats for life on Europa; and (3) Earth analogues and their limitations for Europa… 
Extremophiles: from abyssal to terrestrial ecosystems and possibly beyond
The anthropocentric term “extremophile” was introduced more than 30 years ago to describe any organism capable of living and growing under extreme conditions—i.e., particularly hostile to human and
Polyextremophiles and the Constraints for Terrestrial Habitability
Life on Earth occupies a multidimensional niche space that has yet to be fully described. The niche space of terrestrial life is knowable, and thus, it guides the search for hypothesized life. Since
Multiplication of microbes below 0.690 water activity: implications for terrestrial and extraterrestrial life.
TLDR
Water activity in relation to the limits of Earth's present-day biosphere; the possibility of microbial multiplication by utilizing water from thin, aqueous films or non-liquid sources; whether prokaryotes were the first organisms able to multiply close to the 0.605-aw limit; and whether extraterrestrial aQueous milieux of ≥ 0.605 aw can resemble fertile microbial habitats found on Earth.
Insights Into the Microbiology of the Chaotropic Brines of Salar de Atacama, Chile
TLDR
It is suggested that the characterization of bacterial isolates from a highly lithium-enriched environment has revealed that even at such extreme salinities with high concentrations of chaotropic solutes, scope for microbial life exists, and this work extends the window of life beyondhigh concentrations of MgCl2 to LiCl.
Limits of life in MgCl2-containing environments: chaotropicity defines the window.
TLDR
The exceptional chaotropicity of MgCl(2) is document here, and it is shown that this property, rather than water activity reduction, inhibits life by denaturing biological macromolecules, in hypersaline environments.
Engineering methods for europan relevant biosignature development
One of the primary driving forces for space exploration in the foreseeable future is astrobiology, and specifically the search for a plausible sign of life beyond Earth. Because of the size of the
Astrobiology and the Search for Life in the Universe
TLDR
The requirements for life as the authors know it are examined, with constraints for life, biosignatures, and geosignatures as guidelines, and a strategy to search for life in the universe is elaborated on.
Is Extraterrestrial Life Suppressed on Subsurface Ocean Worlds due to the Paucity of Bioessential Elements?
The availability of bioessential elements for "life as we know it", such as phosphorus (P) or possibly molybdenum (Mo), is expected to restrict the biological productivity of extraterrestrial

TLDR
It is now appreciated that bacteria on Earth can utilize almost any redox couple that yields energy, taking advantage of this energy, while transforming the elements during metabolism, to grow at the expense of inorganic redox couples.

TLDR
“life is a self-sustained chemical system capable of undergoing Darwinian evolution” is one working definition of life that has become influential in the origins-of-life community and is unlikely to prove useful to a remote in situ search for life.
Biodiversity in extreme aquatic environments: Lakes, ponds and streams of the Ross Sea sector, Antarctica
The Ross Sea Sector (RSS) of Antarcticallies between the lines of longitude 150°E and 150°W and contains diverse landscapes with a variety of lakes, ponds and streams. Neither insects nor crustacean
Biogenesis and early life on Earth and Europa: favored by an alkaline ocean?
TLDR
Alkaline brine bubbles embedded in ice in freezing and impact-thawing oceans could have provided a suitable environment for protocell formation and the large number of trials needed for biogenesis, suggesting the existence of an alkaline ocean on Europa.
Water as a Limiting Factor in the Antarctic Terrestrial Environment: A Biogeographical Synthesis
The question is posed: "what limits the presence, distribution, and abundance of life in Antarctica?" Traditionally, continental isolation has been considered to restrict the arrival of new species
Survival of Microorganisms under the Extreme Conditions of the Atacama Desert
TLDR
The solar fluences causing 63% loss in viability (F37-values) have been determined and data are discussed with respect to possible similarities between the climatic conditions of the recent Atacama Desert and the deserts of early Mars.
Biodiversity and ecology of acidophilic microorganisms
TLDR
In view of the continuing expansion of microbial mineral processing as a cost-effective and environmentally sensitive method of metal extraction, and the ongoing concern of pollution from abandoned mine sites, acidophilic microbiology will continue to be of considerable research interest well into the new millennium.
Energy cycling and hypothetical organisms in Europa's ocean.
TLDR
Using reasonable assumptions based on known organisms on Earth, these calculations suggest that chemical oxidation-reduction cycles in Europa's subsurface ocean could support life.
Metabolic Activity of Permafrost Bacteria below the Freezing Point
TLDR
It is suggested that the stationary phase, which is generally considered to be reached when the availability of nutrients becomes limiting, was brought on under conditions by the formation of diffusion barriers in the thin layers of unfrozen water known to be present in permafrost soils, the thickness of which depends on temperature.
