Organic Matter Found In Canadian Meteorite
eldavojohn writes "From what sounds like the opening of an X-Files episode, Canadian scientists have reportedly found in a meteorite organic matter older than the sun at Tagish Lake in Canada. From the article: '"We mean that the material in the meteorite has been processed the least since it was formed. The material we see today is arguably the most representative of the material that first went into making up the solar system." The meteorite likely formed in the outer reaches of the asteroid belt, but the organic material it contains probably had a far more distant origin. The globules could have originated in the Kuiper Belt group of icy planetary remnants orbiting beyond Neptune. Or they could have been created even farther afield. The globules appear to be similar to the kinds of icy grains found in molecular clouds — the vast, low-density regions where stars collapse and form and new solar systems are born.' The article implies that life could potentially survive in these meteorites and maybe even travel through space — supporting the theory that life may have arrived on earth and evolved from that point on."
No, apparently we're here.
I for one welcome our new organic material evolved overlords. And by overlords, I mean us.

I've seen this movie... the organisms evolve... then get sprayed with napalm while Canada gets a dose of Head and Shoulders... or was it the other way round?

So from what I read they structures found COULD assist organic life, but are not actual evidence of them.

Keep in mind that organic does NOT = life, just a precursor to life. Organic molecules/matter are generally just molecules containing carbon and hydrogen making a chainlike skeleton of atoms, with oxygen and/or nitrogen depending on if it is a protein. (Source). This DOES back up the hypothesis that organic molecules can form just as well outside of early earth, as in. It'll be interesting to hear just what the molecules were, but I doubt this will spawn any new theories about the extra-solar genesis of life on earth. It doesn't take special space-dust to provide organic compounds in the early earth - just the atoms from the life cycle of stars spreading heavier elements.

Does that mean the meteorite pulverized some ancient astronouts in a far away galaxy?
THAT might be the reason we haven't gotten contact yet with them; they would've cancelled their space project after such a PR-disaster...

Organic matter has been found in meteorites decades ago.
Life is found most everywhere that it can reach. The only reason we have not found life in space yet is because gravity does a good job of keeping life on the planet and out of space. If there were a place on earth where life could encouter vacuum, it would be a very good bet that life would evolve to cope with it. Trees split water and create sugar using sunlight, animals create water and eat sugar. If you can conceive of a lifeform that can do both of these things, vacuum is a perfectly acceptable environment. In fact there are quite a few "anaerobic" microbes that prefer to not be around oxygen - if they could evolve to handle lower pressures they could make a good candidate for interstellar life travel.

Attributed to Anaxagoras ( http://en.wikipedia.org/wiki/Anaxagoras ) in the 5th century BCE. Basically the idea the precursors to life are everywhere in the universe, allowing that life on earth may have sprung from this source.
It seems plausible. This evidence doesn't prove it though.

Methane (CH4) found for example in vast quantities on the most outer planet, Plutonium, is also an organic compound. But it does not mean that there is, or has ever been, life. First, we need to know when compound it was. Otherwise there's really nothing to talk about.
Im actually interested, how do you measure the age of an object so old, when its not from earth ?
I mean the amount of radioactive materials that fall apart a thousand or so years after being 'inserted' into a certain object is valid only if we know the amount on the env surrounding it.
How do we know how old this thing is without actually being sure where it came from ?
Maybe there was less of the izotope in the env. ?
Or maybe there was much, much more of it ?
This is besides the point if the rock actually contains some fossilized life forms, if its a billion years younger or older, then this fact makes a pretty big difference, right ?
I understand that the age of stars can be measured by the spectrum (iirc, as light travels further/longer it leans towards one of the edges).
I also get how we can determine how we check the basic building block of an object a milion light years away by the light spectrum too.
But the age, when we are not really sure of the exact amount of izotopes in the env. ?
Could somebody educate this fool with a friendly wikipedia link ?
Agreed. But the organic compound has to come from *somewhere*. Even if it came from another planet source, that planet had to somehow receive the materials from somewhere else.
So where does it start?
What kind of "news" story makes such a big deal out of such a fundamentally important claim - "organic matter older than the Sun found in Canadian meteorites", but doesn't say exactly what makes these "globules" qualify as "organic"? The only details about the claimed "organic" matter are that they "resemble minute hollow balls with carbon-rich shells", where "minute" is vaguely implied to be smaller than 10 um^3. (a billionth the volume of a grape).
There's more info detailing that the Yukon is cold and unpopulated than any info about how this carbon is "organic".
In fact, practically all carbon on the Earth is older than the Sun. Carbon is produced in the cores of unusually massive stars, then distributed across the Universe after the star explodes in supernova or similarly huge cataclysm. Just composition of carbon, and the other "organic" elements (nitrogen, oxygen and hydrogen) essential to Earth organic chemistry, doesn't make these tiny grains accurately called "organic globules".
Maybe actual science, written by an actual journalist, could report the more important facts behind this sensational headline.

iirc, only the outermost few centimeters of any incoming meteor are ever heated. If you come upon a just-crashed meteorite that is broken open, it will be cold on the inside, and the outside will be cool to the touch in (again iirc) minutes.

There are many examples of life that can survive in the most extreme of places.
Tbere is bacteria that lives quite happily on plutonium fuel rods inside nuclear reactors. The radiation doesn't bother them.
Thnere is bacteria that can synthesis sugars vital for life without photosynthesis from compounds which are lethal to other forms of life. Examples of this have been found at deep sea hot vents. There is even bacteria which lives off methane. Also many different kinds of bacteria and viruses (the lowest known form of life) which can place themselves into a state of suspended animation for thousands and even theoretically millions of year.
Thus, life has many ways to survive in deep space.

He has good novels?
LOL. True story:
Recently, I was trying to chat up a very attractive girl. I mentioned in our harried conversation (she was at work) that I enjoyed reading but hadn't been to the bookstore in ages, blah blah. She told me that she, too, loved to read, and promised to bring in some of her favourites for me. Great, I thought! This could be the start of something interesting.
A few days later I stop in to see her and she smiles and points to a small bag 'o books in the corner. How sweet, right? Well, inside the bag were 4 were Dan Brown novels. Cervantes I wasn't expecting, but Dan Brown? I tried reading one of them (maybe I was wrong about him), but the absence of any writing talent in combination with an absurd plot reminded so much of high school that all I could was groan and put the book back in the bag with the others.
Haven't been back to see her since. It's been a month, but I wonder whether that's not long enough.
A Canadian meteorite, dating from the formation of the solar system, has been found in Canada. Like many other meteorites, it contains organic matters. The article doesn't state it, but it is probably something akin to amino acids. Apparently, it is the first time this organic matter is found in spherical bubbles, that the original article misleadingly calls "globules". As usual, the article is light on technical details but heavy on wild crazy sensationalist extrapolation. The journalist would like to make believe that cells could have existed on these meteorites but unfortunately has strictly no evidence of this.
"The structures are invisible to the naked eye and resemble minute hollow balls with carbon-rich shells. A chunk of meteorite no larger than a grape could contain a billion of the tiny globules.
Theoretically, their hollow-ball shape could have presented a homey environment of concentrated organic matter where early cellular life could develop.
Such theories boast little evidence but raise many intriguing questions. " (emphasis mine)
The Wise adapts himself to the world. The Fool adapts the world to himself. Therefore, all progress depends on the Fool.
I wouldn't believe the dating results for these types of things. There is a big problem with trying to date asteroids, meteorites and such.
m e.html for the details. This is not some crazy idea. Labs already perform corrections on raw carbon dating data due to electromagnetic bombardment into the atmosphere (which affects the amount of carbon isotopes in the atmosphere, which are then inhaled by living things).
f .
Absolute dating assumes that isotopes degrade in a purely statistical manner. There is reason to believe, however, that changes in electromagnetic bombardment of an isotope can affect the decay of those isotopes. Using a simple experimental apparatus, decay rates can be correlated with the phases of the moon, the motions of the Sun and the stars. Go to http://www.21stcenturysciencetech.com/articles/ti
There is also good reason to believe since the Deep Impact mission to Comet Tempel 1 that comets are merely asteroids on elliptical orbits that have picked up the voltage of deep space and then come into range of the Sun's weak electric field. Rather than being the trail of sublimating ice, the comet's coma and tail are evidence of electric machining. This makes sense because asteroids have occasionally been observed to turn into comets near the gas giant planets. If this is true, then this would mean that asteroids are regularly exposed to potentially large amounts of electromagnetic radiation. For more information, go here: http://www.thunderbolts.info/pdf/ElectricComet.pd
This process of electric machining would almost surely affect the dating ages of these objects *if* the experiment linked to above is true. It might also explain why some craters don't quite date to the years that we think they should.
This of course causes all sorts of problems for archaeology, geology and astronomy, and this fact alone might induce a lot of scientists to want to look the other way. So, I wouldn't expect a lot of curiosity on these things so long as they pose such a threat to research that has already been done.

Free books for you? That was really sweet of her.
Perhaps you should have judged her by the act of giving rather than the gift. Rather than being condescending and judgmental (way to make her feel good, champ), you could have scored points and broadened her horizons by thinking about what she gave you and suggesting some other books she might have liked. Sounds like she likes shorter, punchier thrillers.
I'd have given her Gaston Leroux's "Phantom of the Opera", the collected short stories and cartoons of James Thurber, and maybe something short by literary like Ondatjee's "Running in the Family". How on earth can you know she won't like what you like unless you let her read it?
Actually, finding life is very difficult because the necessary conditions for the formation of a single celled organism only exist with very low possibilities.
Keep in mind that we have never manufactured a single living cell with functional DNA in a lab even with conditions entirely under our human control. Pasteur's Law still holds today. If we can't use thousands of years of engineering, including at least 2 decades of advanced bio-medical technology, to manufacture a single funcional cell from non-organic material, do you really expect it to form arbitrarily in space all the time?
We are the product of an extremely unlikely physical/chemical event, and we may very well be alone.
Certainly, organic molecules are required for life as we know it. But there are many other possibilities.
Why do we assume that there is no life in some place we can't explore, like inside the Sun? Certainly there is no life there based on complex carbon molecules. However, what excludes the possibility of life based on such other mechanism?

The fact that "some of her favorites" included Dan Brown novels points to an obvious character flaw (well..at LEAST one) and a serious lack of intelligence. He made an accurate judgement call based upon the fact that he had never met someone previously who enjoyed a Dan Brown that didn't occasionally have fits of chest slapping/attempts to bite their own ear. While this may be a stereotype, and you are OBVIOUSLY the self-righteous asshole who says "Stereotypes are bad!! You should judge every person you meet for the person they are INSIDE!!!!!1!", I and 95% of the rest of humanity couldn't give a fuck. Stereotypes exist because they work. For example:
Man sees bear.
Man recognizes that bear could possibly maul and/or kill man.
Man finds ways to avoid or escape an encounter with said bear.
Stereotype is defined as: 4. Sociology. a simplified and standardized conception or image invested with special meaning and held in common by members of a group.
Just because 1 in 1000 bears may be cuddly and playful rather than deadly and violent does not make the stereotype incorrect.
Also, by ending things at this point and not "taking a chance" as you would likely put it, he is saving time and possible heartache for her rather than taking advantage of her and presenting himself as a pseudo-cultured, pompous, self-important cock, then using this false image of himself to take advantage of her and use her until he is done with her and kicking her to the curb.

In chemistry, "organic matter" refers to hydrocarbons.
Actually, it's not a silly question at all. It's a darned good one. The short answer is that it's a "best guess".
We still don't actually *know* how the solar system formed, and until then, there's no way we can actually definitely say how old the solar system is. What we think is that the system was formed in a nebula as a big cloud of dust that gradually started to clump around a center. As the protostar gathered mass, the cloud started to spin and formed into a disc, called an accretion disc. The theory is that all of the asteroids, planets and comets formed at the same time as the sun. This theory is supported, in that some of our observations have shown accretion discs in nebulae, but we really have no way to actually *prove* that this is how our solar system formed.
The thing is... if that's how our solar system formed, then we're able to measure the age of the solar system by looking at the age of some of the other objects in the solar system. Fact is that most of the objects out in the kuiper belt and oort cloud (think in the 50-100,000 AU radius) are about 4.5-5 billion years old. Given our current model for how the solar system formed, that would mean that the sun is about the same age. There are almost certainly some objects in our solar system that are older than the system itself... either as captured objects from other solar systems (100k AU is halfway to Proxima Centauri), or as objects that were part of the nursery nebula that we formed from.
As to the original article, it's really nothing special at all. "Organic" molecules just mean carbon compounds. The solar system is full of organic molecules. Something like 2/3 of the asteroids in the solar system, especially in the outer solar system, are carbonaceous. Organic != Life. It's cool that we've found a meteorite that's older than the solar system is thought to be, and it's cool that it's carbonaceous... but that's because it's extremely rare that a carbon-based meteorite survives entry into our solar system, and it's also very rare to find a meteorite that's older than the solar system. Finding the two in conjunction is a really cool thing. But it's in now ay proof of extra-terrestrial life.

OK so let me get this straight. You aren't going to give this "very attractive girl" the time of day because she likes Dan Brown novels.... and shes the idiot here.
So did you happen to pick up 'Angels and Demons', brilliant story even if some of his chapters are only 2 pages long. Most of Dan Browns novels that i've read have an underlying love story where the educated hero ends up with the "very attractive girl"...
If you ask me, YOU are the fool in THIS story who is so naive as to turn down the "very attractive girl" because of her taste in writers. How many HAPPILY married men do you know enjoy all the movies he gets dragged along to by his better half?
I think you should get off your high horse, read the books, buy her some flowers and show her a good time, or in the least give her a chance and see if you get along. There are other things to a relationship other than reading books my friend.

Actually, finding life is very difficult because the necessary conditions for the formation of a single celled organism only exist with very low possibilities.
This may well be true, or not. Right now we don't know how life emerged (though we have quite a few hypotheses), so we can't say.
However, you might want to reflect on this: traces of photosynthetic life have been found in the oldest sediments we know of (see Hadean). Fully-formed fossils appear not much later than that. That puts a lower bound for the appearance of modern bacterial lifeforms at about 3.5Gy ago, and we know that bacteria were not the first form of life to emerge (they're just too complicated). Basically, it seems that life appeared on Earth pretty much as soon as it could. That's not quite what you would expect from a "very low possibility" event.
Keep in mind that we have never manufactured a single living cell with functional DNA in a lab even with conditions entirely under our human control. Pasteur's Law still holds today. If we can't use thousands of years of engineering, including at least 2 decades of advanced bio-medical technology, to manufacture a single funcional cell from non-organic material, do you really expect it to form arbitrarily in space all the time?
We have never manufactured a star either - despite the fact that we know how stars work. Yet there are billions of stars in the universe. Our inability to build something is no indication of how easy it is for Nature to build it.
Life is a very, very complicated business, involving the interplay of a large quantity of microscopic compounds. It is quite possible that the easiest way to create a living cell will not be to engineer one in a "top-down" manner, but rather to find a process through which life would originate "on its own".
SImple — they don't. Your last sentence is the assumption used; i.e., that it has spent its life in an environment such as ours. This is a very good assumption, since in order to show any relativistic time dilation before it reaches us an object needs to have had traveled at very high speed or spent time in a very strong gravitational field. In the former case the speed involved would have to incredible; for example, if the meteorite had spent its entire life travelling at 10% of the speed of light (30,000 km/sec), that would only slow down the decay rate by 1%, well within any margin of error. In the latter case, the meteorite would have had to spend its time very close to a black hole (a few km away for a black hole the mass of the Sun), in which case it would be unlikely to escape to get to us anyway.
