    It is, however, still I'd suggest more likely that this is, indeed, another process that we are not yet aware of. There's something exciting about a discovery of something that is not explained by our current understanding (which this is, if the measurements are accurate), but there are a lot of spots where our current understanding may be incomplete. The key point is this:
    our possibilities are more realistically "life in a form we don't currently really understand is on Venus" or "some other process that is not biological is there that we currently don't understand". The latter can cover a lot more parameter space, and the Discussion leads off with acknowledging the lack of information. They would be remiss if they hadn't talked about this as a possibility, but that doesn't make it the most likely one, even if it's the only possibility that's more formulated at this point.

    Not gonna lie "Is there life on Venus?" just doesn't fit the meter.

    I don't even understand what that means.

    Eh, it's a god-awful small affair.

    Sorry, I'm a little drunk and close to bed time, so I was a bit slow on the uptake!

    Probably not

    One thing is certain: it definitely is due to an unknown chemical reaction. Some sort of chemistry, in some form, is occurring to produce these abundant phosphine molecules. But one thing is just as equally uncertain: this unknown chemical reaction could have one of multiple causes. It could easily be due to a geological process, a purely chemical process, or a biological process.

    Although it could be any of those, in principle, betting that biology is the answer is like buying a single lottery ticket and expecting to hit the jackpot. If life is producing this phosphine, it has to somehow survive reacting with the sulfuric acid, and would require phosphine-producing microorganisms to be extraordinarily abundant and efficient. They would need to occupy the full volume of Venus’s temperate zone hazes, and operate near peak efficiency to account for this signal. It’s not impossible, but it’s an absolutely preposterous scenario.

    I hope it’s some of that “good” bacteria

    People I trust who are usually highly skeptical when they read news headlines like this seem pretty astonished by this. Only time will tell.

    But either way, I hope this makes the space community look to Venus again. It might be better to set up a colony floating in the skies of Venus than digging to make one on Mars. (Whenever we get around to doing that kind of thing).

    It describes them as 'giant sperm'. Normally when I think of giant, I think of something that is likely to break bones if it falls on you.

    Btw, Gonopores sounds like the title of a Stephen King book.

    The gyroscopic effect is one of the most counterintuitive classical phenomenon I have ever studied.
    It's cool though.

    No Phosphine

    Results: We find that the 12th-order polynomial fit to the spectral passband utilised in the published study leads to spurious results. Following their recipe, five other >10 sigma lines can be produced in absorption or emission within 60 km/s from the PH3 1-0 transition frequency by suppressing the surrounding noise. Our independent analysis shows a feature near the PH3 frequency at a ~2 sigma level, below the common threshold for statistical significance. Since the spectral data have a non-Gaussian distribution, we consider a feature at such level as statistically unreliable that cannot be linked to a false positive probability.
    Conclusions: We find that the published 267-GHz ALMA data provide no statistical evidence for phosphine in the atmosphere of Venus.
