Astronomers discover complex organic matter in the universe

In today's issue of the journal Nature, astronomers report that organic compounds of unexpected complexity exist throughout the Universe. The results suggest that complex organic compounds are not the sole domain of life but can be made naturally by stars.
Prof. Sun Kwok and Dr. Yong Zhang of the University of Hong Kong show that an organic substance commonly found throughout the Universe contains a mixture of aromatic (ring-like) and aliphatic (chain-like) components. The compounds are so complex that their chemical structures resemble those of coal and petroleum. Since coal and oil are remnants of ancient life, this type of organic matter was thought to arise only from living organisms. The team's discovery suggests that complex organic compounds can be synthesized in space even when no life forms are present.
The researchers investigated an unsolved phenomenon: a set of infrared emissions detected in stars, interstellar space, and galaxies. These spectral signatures are known as "Unidentified Infrared Emission features". For over two decades, the most commonly accepted theory on the origin of these signatures has been that they come from simple organic molecules made of carbon and hydrogen atoms, called polycyclic aromatic hydrocarbon (PAH) molecules. From observations taken by the Infrared Space Observatory and the Spitzer Space Telescope, Kwok and Zhang showed that the astronomical spectra have features that cannot be explained by PAH molecules. Instead, the team proposes that the substances generating these infrared emissions have chemical structures that are much more complex. By analyzing spectra of star dust formed in exploding stars called novae, they show that stars are making these complex organic compounds on extremely short time scales of weeks.
Not only are stars producing this complex organic matter, they are also ejecting it into the general interstellar space, the region between stars. The work supports an earlier idea proposed by Kwok that old stars are molecular factories capable of manufacturing organic compounds. "Our work has shown that stars have no problem making complex organic compounds under near-vacuum conditions," says Kwok. "Theoretically, this is impossible, but observationally we can see it happening."
Most interestingly, this organic star dust is similar in structure to complex organic compounds found in meteorites. Since meteorites are remnants of the early Solar System, the findings raise the possibility that stars enriched the early Solar System with organic compounds. The early Earth was subjected to severe bombardments by comets and asteroids, which potentially could have carried organic star dust. Whether these delivered organic compounds played any role in the development of life on Earth remains an open question.

On the subject of abiotic oil. Coal is clearly formed from organic debris from living creatures. Most oil on Earth is probably formed the same way. But "deep" oil and gas may be different. Organic matter that was part of the raw material the Earth was formed from, that has differentiated from the core, but is still trapped under the lithosphere. There is no reason to suspect that deep methane ever saw the inside of a cow. ;-)

I think you guys might have missed this line:
Nova does not equal either supernova or stars. The key here is the carbon. Carbon is not produced in normal stars nor is much produced in a supernova itself. Carbon is produced by non-sequence stars. That is stars at the end of their life that have not yet gone BOOOM. The novae and supernovae simply distribute the carbon into interstellar space.
Considering the violence of supernovae they may destroy any complex hydrocarbons. Novae and planetary nebulae may be the main source. I think the latter is the least destructive way to get carbon into interstellar space. It should destroy less hydrocarbons that may have formed in the outer envelopes of non-main-sequence stars.

There's no such thing as "abiotic oil"; if there were, the oil companies would be the first to trumpet its existence. All known oil -- even the deepest -- is associated with subduction of oceanic plates under the continental plates. Oceanic plates are like conveyor belts, slowly accumulating organics-rich sediment from the ocean above until they dive under the continent. There, the sediment gets cooked, and all the organics within it converted to oil and gas, which then bubble up toward the surface. That's why all the big oil and gas fields are found along modern or ancient continental shelves, or in places where several proto-continents collided to form today's super-continents (like, the Middle East), and the like.
Fossil fuel exploration companies vitally rely on this bio-geological understanding when prospecting for oil and gas; if it were not for this helpful heuristic, they'd routinely wind up drilling too many dry wells, and bankrupting themselves in the process.

Anyway, we are often pretty limiting in what we think it takes for life. As oxymoronic as "plasma crystals" might be, there might be some semblance of order out there we can't imagine and are missing.
@visionabler: Bad analogy. If we missed all the plants then we're idiots. If you were looking for life from the sat image on Google Maps on said hill, then you are closer to the point I think. The distance from which we are observing this stuff makes it pretty much impossible. Seems to me we are just seeing spectra from complex organic clouds from REALLY far away.
We haven't really ruled out life being anywhere except maybe on some of the smaller asteroids. Definitely not ruled out on Mars or Venus, our next closest planetary neighbors. Finding that organic compounds are more plentiful than we thought is exciting and terrifying at the same time.

I'm sure it's not the same, but that's why I'm curious, our FTIR has trouble with too much of a compound in a matrix - right in front of it's "face". I guess we're looking at much simpler HCs too, but still... fascinating stuff.

I won't say I think stars are life forms, but maybe we shouldn't be closed to the idea. The book I mentioned earlier by Benford uses ultra-low frequency communications between plasma beings outside near the bow shock. Ultra-low with wavelengths on the order of kilometers, something we would be very hard pressed to detect. All I am saying is that our perspective and experience are extremely narrow.

Well maybe its time to lose that notion. Coal and Oil are not remnants of live but primordeal substances, affected by deep living organisms.

Certain species spawn at the times at or near their deaths. Could this be the same or similar for solar systems?
One star begins to die and ejects part of itself as part of that prolonged death. Another star nearby, with differing isotopic composition does the same shortly thereafter, seeding the other remnants of gas and dust and setting up the process for the births of other stars and their solar systems.
It is at least an interesting thought experiment. :)

At their death and all their lives they are doing just that.
RE-creation. All the gases and particulate released eventually combines with the same from other stars and "voila" - a star is born.
"What, are you comparing the stuff spewed out to sperm?"
Sperm is not the only method of reproduction. And - would make for some really ugly star porn...
"I thought matter/energy could only be recycled, not destroyed or created."
Recycling is EXACTLY what we are talking about - into all kinds of "life"-forms. In a universe of infinite possibly, offspring do not necessarily have to be replicas.

No. Flat out no for coal. Coal is from surface plant life. The evidence is clear. It is not just a bunch of black stuff. All forms except the metamorphic anthracite have clear evidence of being from plants. Anthracite looks to just be a metamorphic form of bituminous.
Not if he said coal as well as oil and the there is still no real evidence to support his claim for oil. Indeed there is no evidence that is not covered reasonably well by standard geology.

not sure what they are, but there was a spate of news coverage about them a while back. very interesting!
as for the living star idea, Frank Herbert covered that pretty thoroughly in his novel The Whipping Star. Seems totally plausible to me. As I've suggested many times life is a mechanism for organizing and trapping energy, which many energetic bodies we observe in the universe also do. Energy is energy, organizing and storing it seems to be a basic observed phenomenon.

Ethelread - I THINK you are saying carbon based geologics are all from surface bio forms (Oil included?).
However, if we step back to a largaer scalar perspective - all life forms are originally star-stuff and therefore - primordial. So, carboniferous leftovers are an evolutionarily modified version of primordial stuff... Yes, I think evolution applies to EVERYTHING...:-)

Synthetic oil is made from coal and is made of hydrocarbons. The thing is that the study of organic chemistry, if you take it at college, is inherently about life and used the word ORGANIC. However there is no requirement for a compound of one carbon and four hydrogen atoms be made by living organisms for be called an organic chemical.
