Several observations indicate that the cloud deck of the venusian atmosphere may provide a plausible refuge for microbial life. Having originated in a hot proto-ocean or been brought in by meteorites from Earth (or Mars), early life on Venus could have adapted to a dry, acidic atmospheric niche as the warming planet lost its oceans. The greatest obstacle for the survival of any organism in this niche may be high doses of ultraviolet (UV) radiation. Here we make the argument that such an…

Water–Sulfuric Acid Foam as a Possible Habitat for Hypothetical Microbial Community in the Cloud Layer of Venus

TLDR
It is hypothesize that the unified internal volume of a microbial community habitat is represented by the heterophase liquid-gas foam structure of Venusian clouds, which could harbor a microbialcommunity of different species of (poly)extremophilic microorganisms that are capable of photo- and chemosynthesis and participate in chemical and photochemical reactions, thus supporting ecosystem stability.

A possible biogenic origin for hydrogen peroxide on Mars: the Viking results reinterpreted

TLDR
The conclusion is that the hitherto mysterious oxidant in the Martian soil, which evolves oxygen when humidified, might be H2O2 of biological origin, which has consequences for site selection for future missions to search for life on Mars.

The Venusian Lower Atmosphere Haze as a Depot for Desiccated Microbial Life: A Proposed Life Cycle for Persistence of the Venusian Aerial Biosphere.

TLDR
It is proposed for the first time that the only way life can survive indefinitely is with a life cycle that involves microbial life drying out as liquid droplets evaporate during settling, with the small desiccated "spores" halting at, and partially populating, the Venus atmosphere stagnant lower haze layer.

The prospect of alien life in exotic forms on other worlds

TLDR
A detailed discussion of two possible habitats for alien life which are generally not considered as such: the lower cloud level of the Venusian atmosphere and Titan’s surface environment are provided.

On the possibility of microbiota transfer from Venus to Earth

The possibility of the clouds of Venus providing habitats for extremophilic microorganisms has been discussed for several decades. We show here that the action of the solar wind leads to erosion of

The pale featureless cloud tops of Venus reveal a rich complexity when viewed in ultraviolet. These features result from an unknown absorber brought up from lower atmospheric levels by convection,

Exobiology of the Venusian Clouds: New Insights into Habitability through Terrestrial Models and Methods of Detection.

TLDR
To detect putative venusian organisms, potential biosignature detection methods are described, which include metal-microbial interactions and optical methods, and currently available technology that can potentially be used for modeling and simulation experiments are described.

Proposed energy-metabolisms cannot explain the atmospheric chemistry of Venus

Life in the clouds of Venus, if present in sufficiently high abundance, must be affecting the atmospheric chemistry. It has been proposed that abundant Venusian life could obtain energy from its

Phosphine gas in the cloud decks of Venus

Measurements of trace gases in planetary atmospheres help us explore chemical conditions different to those on Earth. Our nearest neighbour, Venus, has cloud decks that are temperate but hyperacidic.

Pigmentation as a survival strategy for ancient and modern photosynthetic microbes under high ultraviolet stress on planetary surfaces

TLDR
Using non-intrusive laser Raman spectroscopy to recognize the component parts of biomolecules, this work has shown not only the abundance of microbial photosynthetic and photoprotective pigments in situ, but also their spatial distribution within their microhabitat.

UV-B protecting compounds in the marine algaPhaeocystis pouchetii from Antarctica

Phaeocystis pouchetii (Hariot) Lagerheim is widely distributed in polar waters, and forms massive near-surface blooms in the marginal ice-edge zone around Antarctica during spring and summer. UV

Chloroflexus aurantiacus and ultraviolet radiation: Implications for archean shallow-water stromatolites

TLDR
The apparent UV resistance of chloroflexus and the effectiveness of iron as a UV-absorbing screen in sediments and microbial mats are suggested to be likely mechanisms of survival of early phototrophs in the Precambrian in the absence of an ozone shield.

Reassessing the possibility of life on venus: proposal for an astrobiology mission.

TLDR
With their similar size, chemical composition, and distance from the Sun, Venus and Earth may have shared a similar early history and it is possible that life could exist in restricted environmental niches, where it may have retreated after conditions on the surface became untenable.

A new purple sulfur bacterium isolated from a littoral microbial mat, Thiorhodococcus drewsii sp. nov.

TLDR
A new strain of purple sulfur bacterium was isolated from a marine microbial mat sampled in Great Sippewissett Salt Marsh at the Atlantic coast and physiologically differs considerably from all other members of the Chromatiaceae, including Trc.

Venus, Mars, and the ices on Mercury and the moon: astrobiological implications and proposed mission designs.

TLDR
A hierarchical mission design is envisioned that includes spaceborne (orbital), atmosphere, surface, and subsurface agents working in concert to allow for sufficient mission safety and redundancy, to perform extensive and challenging reconnaissance, and to lead to a thorough search for evidence of life and habitability.

An archaeal iron-oxidizing extreme acidophile important in acid mine drainage.

TLDR
The presence of this and other closely related Thermoplasmales suggests that these acidophiles are important contributors to acid mine drainage and may substantially impact iron and sulfur cycles.

UV PROTECTION IN CYANOBACTERIA

TLDR
The effects of and responses to UV-B at the physiological and molecular levels are summarized and data on the influence ofUV-B irradiation on the proteome of the terrestrial cyanobacterium Nostoc commune is presented.

Energetics of overall metabolic reactions of thermophilic and hyperthermophilic Archaea and bacteria.

TLDR
It is shown that values of DeltaGr(0) for many microbially mediated reactions are highly temperature dependent, and that adopting values determined at 25 degrees C for systems at elevated temperatures introduces significant and unnecessary errors.
