New analysis: It wasn’t even phosphine detected at Venus

The uncertainty of science: A new analysis of the data used by scientists who claimed in September that they had detected phosphine in the atmosphere of Venus has concluded that it wasn’t phosphine at all but sulfur dioxide, a chemical compound long known to be prevalent there.

The UW-led team shows that sulfur dioxide, at levels plausible for Venus, can not only explain the observations but is also more consistent with what astronomers know of the planet’s atmosphere and its punishing chemical environment, which includes clouds of sulfuric acid. In addition, the researchers show that the initial signal originated not in the planet’s cloud layer, but far above it, in an upper layer of Venus’ atmosphere where phosphine molecules would be destroyed within seconds. This lends more support to the hypothesis that sulfur dioxide produced the signal.

When the first announcement was made, it was also noted as an aside that phosphine on Earth is only found in connection with life processes, thus suggesting wildly that it might signal the existence of life on Venus.

That claim was always unjustified, especially because we know so little about Venus’s atmosphere and its alien composition. Even if there was phosphine there, to assume it came from life is a leap well beyond reasonable scientific theorizing.

It now appears that the phosphine detection itself was questionable, which is not surprising since the detection was about 20 molecules out of a billion. And while this new analysis might be correct, but what it really does is illustrate how tentative our knowledge of Venus remains. It might be right, but it also could be wrong and the original results correct. There is simply too much uncertainty and gaps in our knowledge to come to any firm and confident conclusions.

None of that mattered with our modern press corps, which ran like mad to tout the discovery of life on Venus. As I wrote quite correctly in September in my original post about the first results,

The worst part of this is that we can expect our brainless media to run with these claims, without the slightest effort of incredulity.

We live in a world of make believe and made-up science. Data is no longer important, only the leaps of fantasy we can jump to based on the slimmest of facts. It was this desire to push theories rather than knowledge that locked humanity into a dark age for centuries during the Middle Ages. It is doing it again, now, and the proof is all around you, people like zombies and sheep, wearing masks based not on any proven science but on pure emotions.

Venus results suggesting life downgraded

Surprise! Surprise! Further research and review of the recent results that said phosphine existed in Venus’s atmosphere — which for some immediately suggested the presence of life — has found that the phosphine probably doesn’t exist.

[A]lmost immediately, other astronomers began to criticize the results, with four independent studies pointing out questionable methods or failing to reproduce the results.

Now, after reanalyzing their data, the original proponents are downgrading their claims. Even the most favorable interpretation of their data now suggests phosphine levels are at least seven times lower than first reported, making it a much more tentative finding, the authors reported in a preprint posted on 17 November to arXiv.

Also, observations in other wavelengths detected no phosphine, even though it should have been there if the first study was correct. Furthermore, other scientists have noted that the spectrum features detected might not be caused by phosphine. The sulphur dioxide in Venus’s atmosphere could instead be their source.

Even if phosphine is eventually confirmed, that is not the discovery of life on Venus, as so many in the mainstream press claimed. As I noted when this result was first announced, phosphine isn’t life, it is merely a specific inanimate molecule. That on Earth it only exists in connection with life-processes means nothing. Venus is a very alien place, and there could be any number of inanimate chemical processes that we have no experience with or knowledge of that could produce it there. To claim its discovery suggests the existence of life, or even the possibility of life, is simply junk science.

Tiny amount of rare chemical found on Venus; it is NOT a sign of life

The coming dark age: Scientists today announced that they had detected a tiny amount of the rare chemical phosphine in the upper atmosphere of Venus, and immediately jumped to the absurd conclusion that this was a sign of life.

The international team, which includes researchers from the UK, US and Japan, estimates that phosphine exists in Venus’s clouds at a small concentration, only about twenty molecules in every billion. Following their observations, they ran calculations to see whether these amounts could come from natural non-biological processes on the planet. Some ideas included sunlight, minerals blown upwards from the surface, volcanoes, or lightning, but none of these could make anywhere near enough of it. These non-biological sources were found to make at most one ten thousandth of the amount of phosphine that the telescopes saw.

To create the observed quantity of phosphine (which consists of hydrogen and phosphorus) on Venus, terrestrial organisms would only need to work at about 10% of their maximum productivity, according to the team. Earth bacteria are known to make phosphine: they take up phosphate from minerals or biological material, add hydrogen, and ultimately expel phosphine. Any organisms on Venus will probably be very different to their Earth cousins, but they too could be the source of phosphine in the atmosphere.

To leap from finding twenty molecules out of a billion of a single rare chemical to claiming this is a sign of life is absurd. And yet, this is what these scientists do, in the European Space Agency (ESA) press release at the link above, as well as this Royal Astronomical Society press release.

This discovery is not giving us “a hint of life on Venus.” All these scientists have done is detect a chemical whose formation in Venus’ very alien environment is a mystery. Yes, on Earth this chemical comes from life related activities, but to claim that the presence of biology must explain it on Venus is not science, but witchcraft and the stuff of fantasy. We know practically nothing about the full make-up of Venus’ atmosphere, its chemistry and environment, which makes it impossible to hint at any theories, no less life.

The worst part of this is that we can expect our brainless media to run with these claims, without the slightest effort of incredulity.
