Questions come from the Bluebook question bank. Made by Iskaa303 (Iskander Madikhan).
Despite potential independent confirmation, the apparent detection in 2020 of phosphine (PH3)—a gas that on Earth almost exclusively derives from biological sources—in Venus’s cloud deck remains controversial, in part because Venus is thought to be uninhabitable. To evaluate such a finding’s plausibility, William Bains et al. modeled multiple abiotic PH3 pathways, including geochemical, atmospheric, and photochemical reactions, but none adequately explain the observed levels of PH3. If Venusian PH3 does exist, it would indicate insufficiencies in the current consensus on Venus’s chemistry.
