Ancient Venus and Earth may have been similar in crucial ways for the development of life, such as liquid water oceans, land-ocean interfaces, favorable chemical ingredients, and energy pathways. If life ever developed on, or was transported to, early Venus from elsewhere, it might have thrived, expanded, and then survived the changes that have led to an inhospitable surface on Venus today. The Venus cloud layer may provide a refugium for extant life that persisted from an earlier more…

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.
Production of ammonia makes Venusian clouds habitable and explains observed cloud-level chemical anomalies
TLDR
The model predicts that the clouds of Venus are not entirely made of sulfuric acid, but are partially composed of ammonium salt slurries, which may be the result of biological production of ammonia in cloud droplets, and predicts that they are more habitable than previously thought, and may be inhabited.
Potential for Phototrophy in Venus' Clouds.
TLDR
Venus' signature phototrophic windows and subwindows overlap with the absorption profiles of several photosynthetic pigments, especially bacteriochlorophyll b from intact cells and phycocyanin, and Venus' light, with limited UV flux in the middle and lower clouds, is likely quite favorable for phototrophy.
Phosphorus in the Clouds of Venus: Potential for Bioavailability.
TLDR
The VeGa data indicate that a plentiful phosphorus layer exists within a layer that reaches into the lower venusian clouds and exceeds minimum P abundances for terrestrial microbial life and the work combines the results of the VeGa measurements and focuses on P as an inorganic nutrient component and its potential sources and chemical behavior as part of multiple transformations of atmospheric chemistry.

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.

Astrobiology and Venus exploration
For hundreds of years prior to the space age, Venus was considered among the most likely homes for extraterrestrial life. Since planetary exploration began, Venus has not been considered a promising
Venusian Habitable Climate Scenarios: Modeling Venus through time and applications to slowly rotating Venus-Like Exoplanets
One popular view of Venus' climate history describes a world that has spent much of its life with surface liquid water, plate tectonics, and a stable temperate climate. Part of the basis for this
Was Venus the first habitable world of our solar system?
TLDR
A suite of 3-D climate simulations using topographic data from the Magellan mission, solar spectral irradiance estimates for 2.9 and 0.715 Gya, present-day Venus orbital parameters, an ocean volume consistent with current theory, and an atmospheric composition estimated for early Venus find that such a world could have had moderate temperatures if Venus had a rotation period slower than ~16 Earth days.
Life in the Clouds of Venus?
WHILE the surface conditions of Venus make the hypothesis of life there implausible, the clouds of Venus are a different story altogether. As was pointed out some years ago1, water, carbon dioxide
Causes and timing of future biosphere extinction
We present a minimal model for the global carbon cycle of the Earth containing the reservoirs mantle, ocean floor, continental crust, biosphere, and the kerogen, as well as the aggregated reservoir
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 Hot Spring Hypothesis for an Origin of Life
TLDR
The hypothesis that protocells aggregating into a hydrogel in the intermediate moist phase of wet-dry cycles represent a primitive progenote system is proposed and used to posit where life might also have emerged in habitats such as Mars or Saturn's icy moon Enceladus.
