Astronomers discover complex organic matter in the universe
The University of Hong Kong ^ | October 26, 2011

Posted on 10/26/2011 11:05:29 AM PDT by decimon

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.

I have long wondered that, if oil is made by a process that starts with biomass, and slowly is pressed and processed into crude petroleum...

Where is the unfinished oil? There ought to be some freshly started stuff that’s not oil yet, but will be in some thousands of years. Where’s the stuff that’s only half done?

Good question. Bad speeling.

Why aren't we out at Titan already?

We screwed the pooch when we made the Apollo system a lawn ornament in Houston.

An ever-regenerating oil supply...mo more “peak oil” worries.

"...and so we can surmise from this that millions of years ago space alien dinosaurs came to visit here on Earth and that's why our oil comes from a far away galaxy....."

There are coal specimens that show plant structures but I believe you are right about oil and natural gas. It seems to me that oil is a naturally occurring substance as unrelated to fossils as iron ire is.

Or, coal and oil are *not*. :')

That would be the great spirit.

The American Indians are said to have worshiped the Great Spirit and in the movie McClintock depicting a gathering of the clans off the reservation, the leaders wave their arms and cry Whiskey, whiskey

“Where’s the stuff that’s only half done?”

Would peat fit that definition? I live on an old peat bog.

The same way a human body can lose nearly all of its blood and refill itself. The earth is a living thing. The universe is a living thing. There is nowhere in the universe where there is NOTHING.

From the Nature letter:

The detections of discrete and broad aliphatic spectral features suggest that the carrier of the unidentified infrared emission features cannot be a pure aromatic compound. Here we report an analysis of archival spectroscopic observations and demonstrate that the data are most consistent with the carriers being amorphous organic solids with a mixed aromatic–aliphatic structure. This structure is similar to that of the organic materials found in meteorites, as would be expected if the Solar System had inherited these organic materials from interstellar sources.

So they are saying that they are like the stuff we already know about in meteorites. Now we have evidence that the compounds are not just local.

Fred Hoyle's The Intelligent Universe

Fred Hoyle was an important scientist who worked at the frontiers of astronomy and theoretical physics. In 1983 he published a well-illustrated popular book for nonscientists in which he attacked the whole idea that life originated and evolved on Earth and replaced it by 'intelligent cosmic control'.

“Just think for a minute the massive quantities of organic matter required for pools of oil MILES deep”

I’ve always been troubled by that, but never bothered to do the math.

That is an excellent question. I would like that answered also. It could be there is common material that is pre-petroleum matter and I’m just not aware of it. But I like your question and I would like to know the answer to it.

I don’t know. Maybe? But I would think that there’s also got to be a liquid form of proto-petro goo that isn’t petroleum yet, but merely needs the curing time, pressure, and whatever else it takes. Sort of like the wort that just needs some cooking and fermentation time to become beer.
