Uninhabitable
- While the present day surface of Venus is uninhabitable, the lower-cloud layer lies in the region of the atmosphere where pressure-temperature conditions are suitable for life (47–57 km altitude).

Feb 22, 2023 · For early Venus, the question of stable surface water is closely related to tectonics. We discuss potential transitions between stagnant lid and (episodic) tectonics with crustal recycling, as well as consequences for volatile cycling between Venus’ interior and atmosphere.
Aug 21, 2020 · Top panel: Cloud cover on Venus is permanent and continuous, with the middle and lower cloud layers at temperatures that are suitable for life. Bottom panel: Proposed life cycle.
Sep 26, 2023 · Venus is remarkably similar to Earth in many ways, but saying its surface is unsuitable for life is a drastic understatement. In this episode of Dead Planets Society, our hosts attempt to...
3 days ago · The surface of Venus is a hellish place. Suffocated by a thick atmosphere, pressure on the Venusian surface is 92 times greater than on the surface of Earth. Temperatures sit at a staggering 863°F (462°C), which is sufficient to melt lead.
Oct 7, 2021 · The water activity of Venus, which is hypothesized to be suitable for the survival and proliferation of life, is further discussed below. While present Venus is a parched world (Donahue and Hodges, 1992 ), hypothetical life may have found safe haven in the clouds, where some water vapor remains.

The surface itself is unlikely to be habitable to life as we know it: Temperatures on the Venusian ground average around 464 degrees Celsius (867 Fahrenheit). Life's chemistry requires a solvent (here on Earth, that's water), and those temperatures are incompatible with any liquid.
It has long been known that the surface of Venus is too harsh an environment for life [1, 2]. Observations from Mariner 2 and Venus 4 spacecraft seem to indicate that the surface of Venus is a hot dielectric carrying temperatures of roughly 427 C.
