Here is a problem that has been quietly gnawing at astronomers for decades.
The standard approach to detecting #life on other worlds involves scanning #exoplanet #atmospheres for #oxygen, #methane, and #ozone, whose presence is difficult to explain without #biology.
It's a clever idea, but it carries a hidden flaw. That entire shopping list was written by studying Earth. It is, inevitably, a search for life like us.
The list of ways that #chemistry alone can accidentally mimic these #biosignature gases is growing faster than the list of new ways to detect life.
Each new false positive scenario demands even more information about the #planet to rule it out, and there is a genuine question about whether that information can ever be gathered exhaustively.
But there is a solution.
#Assembly theory doesn't ask what #molecules are present in an #atmosphere. Instead, it asks how hard they were to make.
Every molecule can be assigned an assembly index, a minimum number of construction steps required to build it from basic #chemical building blocks.
Simple molecules are easy to assemble by chance, but truly complex ones, requiring many sequential steps, don't arise without something doing a great deal of deliberate selection.
That something would then be life itself.

The recent claims of #biosignature detection in the atmosphere of #exoplanet K2-18b does not convince anyone.
A new paper demonstrates that other non-biological interpretations can also explain the data.
Reanalysing the dataset used in the original biosignature detection paper through multiple other models reveals good fits for models that abiological processes could entirely explain.
One particular model that included the hydrocarbon propyne fit the data better than the model containing DMS and its cousin, dimethyl disulfide (DMDS), which was interpreted as biosignature detection April.

Here the red dwarf #K2-18 photographed last night 17th April 2025 from observatory Y71 Makroskooppi. The Webb telescope has detected possible #biosignature signal of dimethyl sulfide/DMS/DMDS gas in the atmosphere of the super-Earth-sized #exoplanet #K2-18b orbiting it.
The star K2-18 is located under the constellation Leo. In this image, there is a field of view around the star about the size of the moon, the brighter star to the right of K2-18 is HIP 56079 with a brightness of 6.7mag.

Astronomers have detected the most promising signs yet of a possible #biosignature outside the solar system, although they remain cautious.
They have detected the chemical fingerprints of dimethyl sulfide and/or dimethyl disulfide, in the #atmosphere of the #exoplanet K2-18b, which orbits its star in the #habitable zone.
On Earth, theyare only produced by #life, primarily microbial life such as marine phytoplankton.

So far today, every news report I've read about #exoplanet K2-18b has got its size and distance wrong, and has described the #biosignature chemicals DMS and DMDS as gases (on Earth, they're both colourless, flammable liquids).
It makes you wonder how accurate all the other stories on the news are...

There isn't a popular #MedicalScience focused on people who had #brainDamage, experienced a #recovery, and experience #IQ on overdrive.
It's noticeable if you haven't had that for a while. Like realizing there's no longer pain, after taking #glucosamine for a while. That-- at least-- is remarkable.
Why is there #nothing on TV but #politics #racism and the #wealthy #rich #wealth #exhibitionists
I put this #SpaceScience channel on. That's good. What else can I learn? Did you ever notice that? There is nothing about how to #solider or test #amperage
Why?
That's is #oldtechnology
What year is the advent of the #transistor? @AceArsenaultIn retrospect, I noticed it when I was young but more interested in #guitar #wizardry than whatever they were doing on #FullHouse
Makes sense now, in #perspective
No wonder I never watched TV.
#epiphanyI want to write more about that, but I have other things to do. There's simply not enough #time
Anyone?
