Cold Sugar Cloud Found in Space 86

Posted by timothy from the limes-are-one-galaxy-over dept.
Roland Piquepaille writes "A cloud filled with simple molecules of sugar has been found 26,000 light-years away from us, near the middle of our galaxy. The 8-atom sugar molecules exist in a gas cloud named Sagittarius B2 at a temperature of only 8 degrees above absolute zero. Too far and too cold to bake your next cake! However, even if chemistry reactions on Earth and in this frigid sugar cloud are very different, astronomers think this discovery "suggests how the molecular building blocks necessary for the creation of life could first form in interstellar space." Please read the original article for more details or just enjoy these illustrations describing how prebiotic chemistry -- the formation of the molecular building blocks necessary for the creation of life -- occurs in interstellar clouds."

      The fact you got modded up to +3 goes to show just how few Slashdotters know much about astrophysics. This proposal is completely infeasible.

      Take a cylinder a meter wide, from here to Alpha Centauri. Tally up how much matter is there inside of it. I would tell you just how little there is, but you wouldn't believe me, so let's go through the math so you know I'm not yanking your chain. On average, there's about one atom per cubic centimeter of space. Thus, in one cubic meter there's about 10^6 atoms.

      One mole of hydrogen, with a mass of one gram, is 6.023 * 10^23 atoms.

      One cubic meter of interstellar space has a mass of 1.6 * 10^-18 grams, or 1.6 * 10^-21 kilograms.

      It's about four lightyears to Alpha Centauri, or 4 * 10^16 meters, approximately. So a cylinder a meter across would have a cross-section of quarter-pi square meters, or about .785m^2. Multiply that by 4 * 10^16 meters and you get a total volume of roughly 3 * 10^16 cubic meters.

      Multiply 3 * 10^16 cubic meters by 1.6 * 10^-21 kilograms per cubic meter and what do you get?

      You get the total mass of all the matter in a cylinder from here to Alpha Centauri. Something on the order of a fraction of a gram. You leave orders of magnitude more matter in a Kleenex when you sneeze.

      You may want to radically rethink your proposal for farming interstellar gas. There just ain't much of it out there.

        Well, you said "On average." In a nebula, isn't the average density of gas a *LOT* higher?

        I am not an expert on this, but nebulas can be readily seen, so their density should be orders of magnitude more.
        • Fine; assume two orders of magnitude more. (That's a huge, huge amount, by the by.) You're still talking about only a gram of matter in a cylinder from here to Alpha Centauri.

          Think about this one for a moment: these nebulae are light-years across, and yet, despite there being light-years of matter there, we can still see stars on the other side.

          • First, let me state that a massive (relatively) object such as a comet or methany-type moon would be a better source for raw materials than a dispersed cloud. Asimov's old story "The Martian Way" (IIRC) illustrates the value of such a concentrated source of H2 and O2. So you're right that mining clouds is probably economically unfeasible.

            That said, there are a lot more questions you can ask before dismissing this out-of-hand.

            A quick web search indicates that some nebulae are about 4 orders of magnitude

    Is "suggests how the molecular building blocks necessary for the creation of life could first form in interstellar space." good science, or a showboating quote?

    I ask because last I checked, "sugar" is hardly a "building block" of life. Proteins, sure, even amino acids which I think are a bit of a stretch in a way, but mere sugar? Sugar builds nothing and is only slightly more complicated than water, compared to even a simple protein, AFAICS.

            No, a Carbohydrate has the generic formula CnH2nOn, wheras a hydrocarbon has the generic formula CnH2n. Furthermore, the conversion between the two is chemically quite challenging.

      How do you use a telescope to determine the MOLECULAR structure of an interstellar cloud???

      Same way you determine the molecular structure of a compound sitting on the lab bench. Molecular structure is usually detemined by spectroscopy - looking at the electromagnetic radiation the compound absorbs/emits. (What - you thought we used a BIG microscope?) They probably looked at the spectrum of the cloud, and saw charachteristic wavelengths missing and/or present, and concluded that it was due to the presence of the "sugar" molecule.

      BTW: The "sugar" molecule they found is glycolaldehyde. While technically a sugar from a chemist's point of view [it obeys the C(n)H(2n)O(n) rule - here n=2], it would hardly be considered a sugar from a biochemist's or nutritionist's one. It's only a two carbon molecule, and isn't even on any of the normal metabolism paths. Although there probably is a bacteria that can digest it (bacteria can digest practically anything) this "sugar" would probably be non-nutrative - if anything it would give you gas.

      Oh ... and in case anyone is wondering, yes, I *am* a biochemist.

        As the article mentions, the detection of glycolaldehyde is of interest because it is a precursor to ribose. We're not talking about metabolic processes here - we're talking about the availability of the very basic chemicals that formed the first nontrivially self-replicating collections of molecules.

        Glycolaldehyde is also of interest because it is involved in an autocatalytic reaction that essentially converts formaldehyde into glycolaldehyde. As such, it is one of the most fundamental examples of self-replicating molecules. Certainly not nearly as complex as those seen in biology (prions, for example), but the fact that this reaction might take place in the depths of space is interesting - particularly when one considers the possibility of a glycolaldehyde/formaldehyde cloud entering the atmosphere of a planet such as Earth, where conditions are likely much better to sustain the autocatalytic reaction.

        It's somewhat convenient that one degree Celsius and a Kelvin are the same.

        Either way, 8 degrees of anything above absolute zero is pretty darned cold and for most folks it doesn't make a bloody lick of difference what units you use.
