===Phosphine in the atmosphere of Venus===
ALMA participated in the claimed [[Life on Venus#Phosphine|detection of phosphine]], a biomarker, in the air of Venus. As no known non-biological source of phosphine on Venus could produce phosphine in the concentrations detected, this would have indicated the presence of biological organisms in the atmosphere of Venus.<ref name="Greaves et al">{{cite journal |last1=Greaves |first1=Jane S. |last2=Richards |first2=A.M.S. |last3=Bains |first3=W |title=Phosphine gas in the cloud decks of Venus |journal=Nature Astronomy |date=14 September 2020 |volume=5 |issue=7 |pages=655–664 |doi=10.1038/s41550-020-1174-4 |arxiv=2009.06593 |bibcode=2021NatAs...5..655G |s2cid=221655755 |url=https://www.nature.com/articles/s41550-020-1174-4#citeas |access-date=16 September 2020}}</ref><ref>{{cite news |last1=Sample |first1=Ian |title=Scientists find gas linked to life in atmosphere of Venus |url=https://www.theguardian.com/science/2020/sep/14/scientists-find-gas-linked-to-life-in-atmosphere-of-venus |access-date=16 September 2020 |work=The Guardian |date=14 September 2020}}</ref> Later reanalyses cast doubt on the detection,<ref>{{cite journal|last1=Villanueva|first1=Geronimo|last2=Cordiner|first2=Martin|last3=Irwin|first3=Patrick|last4=de Pater|first4=Imke|last5=Butler|first5=Bryan|last6=Gurwell|first6=Mark|last7=Milam|first7=Stefanie|last8=Nixon|first8=Conor|last9=Luszcz-Cook|first9=Statia|last10=Wilson|first10=Colin|last11=Kofman|first11=Vincent|year=2021|title=No phosphine in the atmosphere of Venus|journal=Nature Astronomy|volume=5|pages=631–635|doi=10.1038/s41550-021-01422-z|arxiv=2010.14305|s2cid=236090264}}</ref> although later analyses confirmed the results.<ref>{{cite journal|last1=Clements |first1=David L. |date=12 January 2023 |title=Venus, Phosphine and the Possibility of Life |journal=Contemporary Physics |volume=63 |issue=3 |page=180 |doi=10.1080/00107514.2023.2184932 |arxiv=2301.05160 |bibcode=2022ConPh..63..180C }}</ref> The detection remains controversial, and is awaiting [[Life_on_Venus#Planned_measurements_of_phosphine_levels|additional measurements]].<ref>{{cite news |last1=Sansom |first1=Clare |title=The hellish chemistry of Venus' atmosphere |url=https://www.chemistryworld.com/features/the-hellish-chemistry-of-venus-atmosphere/4013145.article |work=Chemistry World |language=en}}</ref><ref>{{cite journal |last1=Cleland |first1=Carol E. |last2=Rimmer |first2=Paul B. |title=Ammonia and Phosphine in the Clouds of Venus as Potentially Biological Anomalies |journal=Aerospace |date=26 November 2022 |volume=9 |issue=12 |pages=752 |doi=10.3390/aerospace9120752|arxiv=2211.07786 |bibcode=2022Aeros...9..752C |doi-access=free }}</ref>
