Life on Venus Confirmed by 2035


The lower cloud layer of Venus (47.5–50.5 km) is an exceptional target for exploration due to the favorable conditions for microbial life, including moderate temperatures and pressures (∼60°C and 1 atm), and the presence of micron-sized sulfuric acid aerosols.

Recently, scientists have discovered phosphine gas in the atmosphere of Venus that was earlier proposed as a biosignature gas in exoplanet atmospheres.

Will life on Venus be confirmed before 2035?

The question will resolve positive based on strong and conclusive evidence of an extraterrestrial life on Venus. We will apply here the Sagan standard "extraordinary claims require extraordinary evidence" therefore the discovery must be beyond any reasonable doubt.

The question will resolve negative if no evidence of life on Venus is found or the evidence remains inconclusive.
