Countering extra-terrestrial delivery theories of life on Earth.Paper: Formation of Amino Acids and Carboxylic Acids in Weakly Reducing Planetary Atmospheres by Solar Energetic Particles from the Young Sun (April 2023)
– – –
In 1952 the famous Miller-Urey experiment proved that lightning in the atmosphere of early Earth could produce the chemical building blocks of life. New research reveals that solar flares might do an even better job.
“The production rate of amino acids by lightning is a million times less than by solar protons,” says Vladimir Airapetian of NASA’s Goddard Space Flight Center, a coauthor of the new paper.

Early research on the origins of life mostly ignored the sun, focusing instead on lightning as an energy source. In the 1950s Stanley Miller of the University of Chicago filled a closed chamber with methane, ammonia, water, and molecular hydrogen – gases thought to be prevalent in Earth’s early atmosphere – and repeatedly ignited an electrical spark to simulate lightning. A week later, Miller and his graduate advisor Harold Urey analyzed the chamber’s contents and…

If life evolved elsewhere, all you do is shift the location of the problem.
Gee, what is the source of energy that produces lightning? Charge flow…
From the same link : “This doesn’t mean solar flares created life–only the building blocks. How non-living chemicals might self-assemble into a living organism remains a mystery.”
Telescopes ALMA, VLT, JWST are poring in a data deluge of stellar system organic clouds, vast quantities of the building blocks for … fossil fuels!
We need dedicated climate activists to clean up all that mess and make the stellar systems carbon neutral. Not to forget the comet tar snow-balls. Oh wait – these activists a glued to this planet.
Irony aside, the organic soup is almost everywhere to find. Virus sequences are also, even in deep space dust grains.
Huge number of new links here :

Viral sequences belong somewhere in a organics continuum and cellular life.
