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.
- When will the first evidence of extraterrestrial life be discovered?
- Will a human made spaceship enter the Venusian atmosphere before 2030?
- If alien life is discovered in the Solar System before 2050, which place will be the natural environment of the first extraterrestrial (Solar) life-form of which there is conclusive evidence?
