so this is lit as shit. theyre saying there is a source of PH3 in the atmosphere of venus, an atmosphere which rarely has any sort of bond containing hydrogen. this implies it could be life.

however, they also mentioned it appearing near the equator. and that made me remember some articles about phosphine in comets and some others about how asteroids tend to hit our equator more. how much yall wanna reckon a giant comet hit that motherfucker many years back and had ph3 in it? they say that the phosphine would deplete in 10^3 years if it is not renewed, i didnt see any info on whether the concentration changed in their year of observation

here's their bit on anomalous events, which doesnt seem to mention asteroids or comets:

Energetic events are also not an effective route to making PH3. Lightning may occur on Venus, but at sub-Earth activity levels33. We find that PH3 production by Venusian lightning would fall short of few-ppb abundance by factors of 107 or more. Similarly, there would need to be >200 times as much volcanic activity on Venus as on Earth to inject enough PH3 into the atmosphere (up to ~108 times, depending on assumptions about mantle rock chemistry). Orbiter topographical studies have suggested there are not many large, active, volcanic hotspots on Venus34. Meteoritic delivery adds at most a few tonnes of phosphorus per year (for Earth-like accretion of meteorites). Exotic processes such as large-scale tribochemical (frictional) processes and solar wind protons also only generate PH3 in negligible quantities (W. Bains et al., manuscript in preparation, submitted to Astrobiology as ‘Phosphine on Venus cannot be explained by conventional processes'; also see Extended Data Fig. 10).

i do like that theyre going for the gold and asking for a new visit to venus and some new telescopes though.

    Fuck I typed smtn and closed the window.

    So I find this super interesting and have since reading: Life on venus CS Cockell - Planetary and Space Science, 1999 - Elsevier

    I think that the potential applications for a bacterium from such an environment for bioremediation on earth would be very impactful. As Venus was held up as an example of what we would be headed towards on earth if climate change wasnt addressed.

    However I believe now that as we grapple with becoming a stage 1 on Kardashev scale we will be unable to deal with the existential pit fall of such a transition due to survailence/information/data based capitalism.

      I also beleive that the Anunnaki, are a race of large & potentially winged humanoids see the nephalim that interacted with humanity during the Akkadian empire in order to engage in genetic engineering to create new species but I dont have a scientific article to back that up just my trance based conversations with Enki and Ianna.

          I dont wanna derail a science based discussion with my spiritual stuff but 2 years ago I did the ritual of the gates in Simon's necronimicon and during that scryed visions during the trance brought on by the rituals that were super enlightening.

      I know it’s not related but it’s funny to see Elsevir outside of a work context. I edit for an Elzevir journal and we’ll often have reviewers turn us down because they hate Elsevir’s business practices. I’m sympathetic but come on you’re just making my job harder, I didn’t make this publisher be a shit
