Ang hinuha na kasalukuyang mayroong buhay sa [[Benus (planeta)|Venus]] ay isang matagal nang haka-haka. Ang mga teorya ay napabulaanan nang matindi mula pa noong unang bahagi ng 1960, nang magsimula ang pag-aaral ng planeta sa pamamagitan ng spacecraft at naging malinaw na ang kapaligiran nito ay malala kumpara sa Daigdig.
Ang lokasyon ng Venus na malapit sa [[Araw (astronomiya)|Araw]] kaysa [[Daigdig]] at ang matinding [[epektong greenhouse]] na nagpapataas ng temperatura sa rabaw hanggang sa halos {{Convert|735|K|C F}}, at ang presyon ng atmospera 90 beses kaysa Daigdig, ay gumagawa ng kondisyon na maaaring imposible sa rabaw ng planeta ang [[buhay]] nakabatay sa tubig na pamilyar sa atin. Gayunpaman, ilang siyentipiko ang nag-isip-isip na ang mga [[ Thermoacidophilic |thermoacidophilic]] [[ Extremophile |extremophileekstremopilong]] [[mikroorganismo]] ay maaaring umiiral sa mahinahin, asikong matataas na layer ng atmospera ng Venus.<ref>{{cite news|url=https://www.newscientist.com/article/dn2843-acidic-clouds-of-venus-could-harbour-life.html|title=Acidic clouds of Venus could harbour life|work=New Scientist|first=Stuart|last=Clark|date=26 September 2003|accessdate=30 December 2015}}</ref><ref>Redfern, Martin (25 May 2004).
