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.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

Fortunately, BepiColombo will be doing a much closer flyby of Venus for a gravity assist later this year, and we should have a shot at some better data from its spectrometer out of that.
I don’t think there is, or ever was, life on Venus, but I do think we’ve spent too little time studying our closest neighbor up close, so I do hope that NASA selects one of the Venus mission proposals (DAVINCI+ or VERITAS) for the final Discovery 15/16 program downselect this summer, not least so that we can better understand how these false readings can happen. That in turn could improve our ability to detect where it actually does exist on other worlds..
If we do find life of any kind someplace else in the solar system what exactly will happen?
Will they close off the planet to any physical research just in case we contaminate it?
Will they try to take samples and risk contaminating the Earth with them or us contaminating them while we catch them?
I am for not caring and just letting nature take its course. Survival of the fittest.
