Stormy Alien Atmospheres May Spark Seeds of Life

Posted by Soulskill on from the or-facehuggers dept.

astroengine writes "In research presented at the Meeting of the Royal Astronomical Society in London on Friday, astronomers discussed the dusty, stormy atmospheres of exoplanets and brown dwarfs and how they could be hothouses for the formation of prebiotic molecules. These are organic molecules that are known to form the building blocks for life as we know it. 'The atmospheres around exoplanets and brown dwarfs form exotic clouds that, instead of being composed of water droplets, are made of dust particles made of minerals,' said astronomer Craig Stark, of the University of St. Andrews, Scotland. The idea is that lightning storms generate copious amounts of highly charged ions and electrons, which then get stuck to dust particles, using them as miniature prebiotic chemistry factories. Of particular interest is the formation of formaldehyde, ammonia, hydrogen cyanide and the amino acid glycine, all of which underpin Earth's biosphere."

      Well I believe the idea would be that Shannon and his basic work on information theory made inroads to the study of complexity. And the common and flawed argument that the anti-science crowd throws about is that various parts of biology, or in this case the most basic forms of life, are irreducibly complex. And that it's SOOOOO rare of a chance that these amino acids and whatnot would randomly bump into each other to form a self-reproducing molecule that's it's an absurd theory.

      So it's important to understand what the term "complex" means in a technical sense and how complex systems can arise from simpler things.

      Before you can answer "Why not elsewhere?" You need to figure out how it began here. Explaining the creation of organic molecules in an early earth atmosphere is one thing. Even getting to the point of self-replicating molecules is not too terribly difficult. Getting from self-replicating molecules to even the simplest life -- that's the hard part and until we can figure that out (and no, it doesn't require a deity), anything we say about alien planet atmosphere sparking life is pure conjecture.

      As for these inquisitive young minds, let's say we whet their appetite by these stories, what happens when what we've told them is shown to be untrue? We end up with a bunch of cynical adults who don't trust science, which leads to all sorts of problems (climate change and evolution are prime examples of this).

      Self-replicating molecules IS the definition of life. At least, you know, it's good enough for me. If you start down the path of arguing what is and isn't alive, you just end up in a philosophical dead end.

      anything we say about alien planet atmosphere sparking life is pure conjecture.

      It's conjecture, but it's not pure conjecture. It's an informed and rational estimation given a small but not insignificant amount of data on the subject. The probability that the conjecture is true is low, but not zero. It takes a mountain of effort to raise that probability, and it never gets to 100% for anything, but sometimes it's worth it and all in all I'm a fan of efforts trying to peer past the veil of uncertainty.

      Those are words of wisdom. Which is why you never sell anything as hard-set fact. These are dreams and conjecture. Do alien atmospheres spark the seeds of life? They may. If you're uncomfortable with that uncertainty, then science might not be for you. But I'll light my sparks with dreams that might come true. (Along with a good sci-fi book. Have you read Paolo Bacigalupi's Calorie Man series? Good stuff)

      My question though is at what point those molecules become alive?

      When they bump into each other and form something that reproduces itself. Abiogenesis. After that happens evolution kicks in and they're on the course towards launching rockets towards Earth and killing us all.

      When do they start reproducing

      Good question. Once you get the primordial soup, they bump around randomly until they form things of interest. Cell membranes are easy. Lipids naturally cling to each other and make little bubbles. There's a tough call about which part of the next process came first and how they made the other half: Proteins or nucleic acids? They kind of make each other. Like I said, this is a good question.

      or even get the will/understanding the need to reproduce/split to survive?

      I don't think that bacteria particularly have/need any amount of willpower or understanding to reproduce, split, and/or survive. They just need to do it. We personify these things a lot as a teaching aide, like saying the river water WANTS to flow to the sea, but they're just dumb cells.

      How does that transformation occur that takes this energy from lightning or whatever and converts it to life?

      Oh, that's easy: the energy from lightning converts some common chemicals into some other chemicals. Specifically, methane (CH4), ammonia (NH3), water (H2O), hydrogen sulfide (H2S), carbon dioxide (CO2) or carbon monoxide (CO), and phosphate (PO43-) get electrocuted and can turn into, among other things, amino acids. These chemicals are the basic building blocks of life and the idea is that if you bump them together enough that they'll form into something that reproduces. That's the definition of life.

      Funny how our everyday language separates life from the rest of the universe, when all evidence points to it being inseparable. Perhaps that would change if we all took Sagan's POV and thought of life as the mechanism by which the universe that observes itself.

      Also from the Earth's history we might assume liquid water is required for single-celled critters while O2 is required to make the cologene (sic) to bind them into multicellular critters. It's said that Europa has an ocean and volcanic vents, it's also said the ocean is oxygenated by radiation and subduction of the ice crust. If there are multicellular critters in Europa's ocean it's likely the evidence will have been thrown onto the surface by ice volcanos. As you say, it's just a question of finding it, but we have narrowed the search space significantly simply by concentrating on "life as we know it".

      Well maybe this is my chance to rescue someone! To disabuse them of the notion that Buddhism offers the solution to the existential crisis that is life. For samsara does not only mean the endless cycle of rebirth but is equivalent to the endless cycle of suffering - for birth indeed in and of itself is considered suffering in Buddhist terms. An endless cycle of birth (and thus suffering), with the only way out being to stop being born - to stop rebirth in its tracks and to no longer exist in this world. Truly the solution would be suicide if only that option didn't lead one to getting reborn again.

      Yet is this quite satisfying? Is any form of existence truly suffering? I say not. I say life is intrinsically pleasant and enjoyable, and it is only the rudimentary animal self blown out of all proportion that leads us to think it's all pain and suffering. Drop this notion, contemplate what it truly means to be alive - and one can find a peaceful ambiance all about, delightful in and of its very self. This truly is the answer to the problem of humanity's suffering. Follow it to its end and one finds Ultimate Fulfillment - here and now, not as a result of a hoary altered state of consciousness which deludes one into thinking that one doesn't really exist - for one does, albeit as a flesh and blood body only.
