Stars Found To Produce Complex Organic Compounds 93

Posted by samzenpus from the galaxy-seeding dept.
InfiniteZero writes "Researchers at the University of Hong Kong observed stars at different evolutionary phases and found that they are able to produce complex organic compounds and eject them into space, filling the regions between stars. The compounds are so complex that their chemical structures resemble the makeup of coal and petroleum, the study's lead author Sun Kwok, of the University of Hong Kong, said."

      Stardust is exactly right. Most of the heavy elements (non-hydrogen or helium) were produced, if not by the mechanism described in the article, in the death throes of heavy stars that go supernova. All the Big Bang gave us was a lot of hydrogen, a small amount of helium, and a negligible quantity of everything else. The rest had to wait for the stars and stellar nucleosynthesis [wikimedia.org] to be produced.

    The 'question' of how life started on our amazing planet gets easier to 'answer' with every new discovery.

    "Just the facts, sir." (apologies to Sgt. Friday)
    To me the facts are even more amazing and awesome than any myths or superstitions that persist, to explain our world and universe.

    There are many times I feel humbled and awed by the scientific discoveries and technological advances I have witnessed in my lifetime. (reference: I'm coming up TOO QUICKLY! on 54 years old)

    Just the amount and nature of 'former Sci-Fi' tech that has become reality in my time boggles my mind...Wow!

  • Forget fusion, the next source of energy is STAR POOP!!! Now, who do we send out to gather it?

  • Stars are too hot for compounds to exist in them. The componds are actually synthesized in what TFA calls the circumstellar enviroment.

    • Just my first thought too but...

      TFS is actually correct, as it is taken directly from the article.
      And, no it don't says it produces it IN the star, but that the star produces it. That is, if the star produces the compounds around it, it is still the star that makes is, just not inside it.

      So for a long long time in /. history, the summery is actually very correct :)

    "The compounds are so complex that their chemical structures resemble the makeup of coal and petroleum"
    Who cares if it produced a little bit or even a lot of fuel like substances, could they have produced the organic matter needed to kick start life?
    From what I understand the only real missing link in explaining how life started on this planet is the formation of some relatively simple organic compounds (not that they do not have some very good theories and promising results).

    • Relatively simple? We've not managed to work out an experiment to form a protein through nature, and we are a long way off from figuring out the formation of the first functional nucleic acid chain. That's pretty complicated stuff. After that, we gotta work out a chain that can replicate itself, which is hugely complicated. We've managed to form some amino acids, and even making anything past the simplest of them is pretty difficult. Still, the fact that any organic compounds are produced from stars is

        I think you need to work on understanding time scales, quantities, and probability.

        If life were started by an accident so improbable that in the entire history of experimentation (starting back with flint knapping) it would be unreasonable to expect it to have happened, it could still be nigh unto a certainty given the whole planet's oceans, and a billion years to work in. Now that's NOT the most likely way for complex molecules to have originated. I'm no expert, but I suspect that small volcanic bubbles

The long time frames and random factors are all in relation to producing the proper conditions come into alignment to allow the reaction to take place. My point was, the molecules are so complex that we are not able to reverse-engineer them to come up with any set of conditions that might conceivably have occurred in nature that, when recreated in a experiment, creates the compounds again.

            The problem isn't that we can't come up with an explanation. The problem is that there are LOTS of potential explanations, and the evidence is too scanty to really eliminate most of them.

            E.g., we say that DNA couldn't have been the first replicator, because it isn't stable enough. But it could have evolved in a micro-clime that happened to stabilize it. This is quite improbable, but it can't really be ruled out. (It is so improbable that nobody seriously considers it, which is why I mention it as an exa

  • Since when are coal or petroleum complex molecules? Coal is to varying degrees just carbon (the harder the coal, more it is just plain C) and petroleum is chains of Carbon with hydrogens haning off the sides. These are pretty simple molecules.

  • I'm horrified that this made it to Nature. It has certainly sealed my opinion that Nature publishes based more on name than content. Aside from nitpicky little things like leaving the structure such a horrible looking mess (when even my undergrads know how to use the clean-up tool in ChemDraw), why do they think that they can recreate a molecular structure from an IR spectrum obtained from a heterogeneous point source? Occam's Razor would suggest that this bizarrely complex structure isn't what they are act

      Doesn't one of Saturn's moons have a lot of petroleum? Seems to me that there was an article posted some time ago here that was about an engineer that said that the quantities of oil produced by rotting material was more than should be expected and thus there had to be a different source and pointed out a spectrogram that showed significant quantities on one of Saturn's moons.
