The hypothesis that there may be microbial life in the clouds of Venus is revisited, presenting a life cycle enabling such life to persist amid extreme conditions.
We argue that it is essential for life to reside within liquid droplets to prevent critical water loss, a fate that befalls free-floating microorganisms.
The droplets in Venusian atmosphere inevitably grow larger, leading them to sink to hotter layers of the atmosphere, thus posing a challenge for microbial survival.
Our proposed life cycle suggests that for life to survive indefinitely in Venus' clouds, microbial organisms must undergo a drying process to endure the harsh conditions.
