I think the best commentary on this discovery was published by Forbes - LINK.

To quote the actual authors of the papers in question:

Quote:
Even if confirmed, we emphasize that the detection of [phosphine] is not robust evidence for life, only for anomalous and unexplained chemistry.
We have a history of jumping to 'alien life' conclusions, and as the saying goes "extraodinary claims require extraodinary evidence" and here we haven't ruled out the most simple of explanations yet - geological or purely chemical processes.

I agree its certainly not clear cut evidence of life. But interesting evidence potentially pointing in that direction

Not particularly. Phosphine can be attributable to geochemistry, photochemistry, or biochemistry. At this point we do not know in which direction the evidence is pointing. To rule out geochemistry and/or photochemistry we'd have to actually detect life and show direct link to phosphine production. Until then the first two explanations are far more likely than life, they are just not as news worthy and bring fewer grants.

Itís been theorized before this that life could live high in the atmosphere of Venus. So this was cool to read. Obviously thereís a lot of stuff to rule out first, but I think itís interesting considering Venus is right next door.
