Sofia-telescope found no evidence of life on Venus. And there is no phosphine in that planet's atmosphere. So that thing means that Venus is dead. But the question is why the first telescope saw phosphine in the Venu's clouds and then that phosphine is gone. The wrong calibration might be the problem. But how telescope couldn't detect that the source of phosphine is in Earth's atmosphere? There was not very much phosphine in Venus. Image Sofia-telescope So maybe the reason for that trace was some chemical reaction where some volcano released phosphorous into Venus's atmosphere. And then things like lightning caused a reaction where carbon monoxide reacted with phosphorous. There is a possibility that the lightning destroyed CO or CO^2 molecules. And then phosphorous could interact with hydrogen forming PH3. So there are no lifeforms in Venus's clouds. https://scitechdaily.com/sofia-finds-no-phosphine-a-potential-sign-of-life-on-venus/ https://www.universetod
