A new article in Nature Astronomy reports that non-oxidized phosphine gas (PH3) has been detected in the upper atmosphere of Venus. This is a surprising discovery, as phosphine gas was not expected to be stable in that environment. This suggests that some unexpected process is creating the gas, which could include biological processes.
There is much study still to be done, of course, but this is an exciting discovery! Be sure to check out the paper below; the raw data is publicly available for anyone who wants to do their own analysis as well, linked at the end.
