      We definitely need more confirmation of PH3. But uh... this ain't it, folks.https://twitter.com/DrFunkySpoon/status/1310893866342592518 …

      Wow! Potential biosignature gas on Venus independently found in archival spacecraft data! “Is Phosphine in the Mass Spectra from Venus’ Clouds?” Using Pioneer entry probe data from 1979. “We find that LMNS data support the presence of phosphine.” https://arxiv.org/abs/2009.12758?fbclid=IwAR2DCqv3h6wxBD0kbln6bQ3BVIsbgnJtsSq76oj8vYvPn3asU8Lf0U3nmAo …

      The signals that they are trying to separate are very small and very close together. And if it *is* in this spectrum I would want to see it at more than just one altitude. Make absolutely sure it's not noise.

      They're not wrong in saying that the data could support the presence of PH3. But they certainly didn't unambiguously detect it, either.

      Gotcha. Yeah there is room for self-deception on this kind of stuff. Comforting to know that many teams are likely frantically working on various independent confirmation methods

      Yeah definitely! It's exciting to see so much Venus work being done! 🥰

      Interesting to see some folks have made up their minds that it absolutely is not there. Which is just as silly as being certain it is there at this point… Looking for it in archival data is a good move, but if it were a clear signal it likely would have been published before...

          Nothing is ever certain when it comes to Venus 😂
