Evidence of Extraterrestrial Life Found

[CaptainBlowhole]

Its fairly safe to say that this is conclusive proof of the existence of extraterrestrial life.
An astrobiologist has taken samples of some rare meteorites that are called carbon
and analyzed the fragments under an electron microscope and found a fairly abundant trove of fossilized bacteria from beyond the Earth and he published a paper of his findings and allowed all scientists to review it prior to publication.

Here is an example of the bacterium from the meteorite:

As much as I want this to be true, I'm sure it will somehow be disproved.

[StanUpshaw]

Probably not disproved...more likely it will be supported by some researchers, but not enough to be overwhelmingly convincing.

Discoveries like this have happened before (http://www2.jpl.nasa.gov/snc/nasa1.html), and after the initial headlines, you never hear about them again.

Still not "intelligent life" though. The "S" tattoo on it's back clearly shows that it's nothing but a white trash tattoo monkey.

Here's what noted science blogger and curmudgeon PZ Myers had to say:
Did scientists discover bacteria in meteorites?

No.

No, no, no. No no no no no no no no.

No, no.

No.

Fox News broke the story, which ought to make one immediately suspicious — it's not an organization noted for scientific acumen. But even worse, the paper claiming the discovery of bacteria fossils in carbonaceous chondrites was published in … the Journal of Cosmology. I've mentioned Cosmology before — it isn't a real science journal at all, but is the ginned-up website of a small group of crank academics obsessed with the idea of Hoyle and Wickramasinghe that life originated in outer space and simply rained down on Earth. It doesn't exist in print, consists entirely of a crude and ugly website that looks like it was sucked through a wormhole from the 1990s, and publishes lots of empty noise with no substantial editorial restraint. For a while, it seemed to be entirely the domain of a crackpot named Rhawn Joseph who called himself the emeritus professor of something mysteriously called the Brain Research Laboratory, based in the general neighborhood of Northern California (seriously, that was the address: "Northern California"), and self-published all of his pseudo-scientific "publications" on this web site.

It is not an auspicious beginning. Finding credible evidence of extraterrestrial microbes is the kind of thing you'd expect to see published in Science or Nature, but the fact that it found a home on a fringe website that pretends to be a legitimate science journal ought to set off alarms right there.

But could it be that by some clumsy accident of the author, a fabulously insightful, meticulously researched paper could have fallen into the hands of single-minded lunatics who rushed it into 'print'? Sure. And David Icke might someday publish the working plans for a perpetual motion machine in his lizardoid-infested newsletter. We've actually got to look at the claims and not dismiss them because of their location.

So let's look at the paper, Fossils of Cyanobacteria in CI1 Carbonaceous Meteorites: Implications to Life on Comets, Europa, and Enceladus. I think that link will work; I'm not certain, because the "Journal of Cosmology" seems to randomly redirect links to its site to whatever article the editors think is hot right now, and while the article title is given a link on the page, it's to an Amazon page that's flogging a $94 book by the author. Who needs a DOI when you've got a book to sell?

Reading the text, my impression is one of excessive padding. It's a dump of miscellaneous facts about carbonaceous chondrites, not well-honed arguments edited to promote concision or cogency. The figures are annoying; when you skim through them, several will jump out at you as very provocative and looking an awful lot like real bacteria, but then without exception they all turn out to be photos of terrestrial organisms thrown in for reference. The extraterrestrial 'bacteria' all look like random mineral squiggles and bumps on a field full of random squiggles and bumps, and apparently, the authors thought some particular squiggle looked sort of like some photo of a bug. This isn't science, it's pareidolia. They might as well be analyzing Martian satellite photos for pictures that sorta kinda look like artifacts.

The data consists almost entirely of SEM photos of odd globules and filaments on the complex surfaces of crumbled up meteorites, with interspersed SEMs of miscellaneous real bacteria taken from various sources — they seem to be proud of having analyzed flakes of mummy skin and hair from frozen mammoths, but I couldn't see the point at all — do they have cause to think the substrate of a chondrite might have some correspondence to a Siberian Pleistocene mammoth guard hair? I'd be more impressed if they'd surveyed the population of weird little lumps in their rocks and found the kind of consistent morphology in a subset that you'd find in a population of bacteria. Instead, it's a wild collection of one-offs.

There is one other kind of datum in the article: they also analyzed the mineral content of the 'bacteria', and report detailed breakdowns of the constitution of the blobs: there's lots of carbon, magnesium, silicon, and sulfur in there, and virtually no nitrogen. The profiles don't look anything like what you'd expect from organic life on Earth, but then, these are supposedly fossilized specimens from chondrites that congealed out of the gases of the solar nebula billions of years ago. Why would you expect any kind of correspondence?

The extraterrestrial 'bacteria' photos are a pain to browse through, as well, because they are published at a range of different magnifications, and even when they are directly comparing an SEM of one to an SEM of a real bacterium, they can't be bothered to put them at the same scale. Peering at them and mentally tweaking the size, though, one surprising result is that all of their boojums are relatively huge — these would be big critters, more similar in size to eukaryotic cells than E. coli. And all of them preserved so well, not crushed into a smear of carbon, not ruptured and evaporated away, all just sitting there, posing, like a few billion years in a vacuum was a day in the park. Who knew that milling about in a comet for the lifetime of a solar system was such a great preservative?

I'm looking forward to the publication next year of the discovery of an extraterrestrial rabbit in a meteor. While they're at it, they might as well throw in a bigfoot print on the surface and chupacabra coprolite from space. All will be about as convincing as this story.

While they're at it, maybe they should try publishing it in a journal with some reputation for rigorous peer review and expectation that the data will meet certain minimal standards of evidence and professionalism.

Otherwise, this work is garbage. I'm surprised anyone is granting it any credibility at all.

If there's no life beyond our planet what do Astrobiologists study?

Fox News Publishes Fake ‘Exclusive’ About Discovery of Alien Life (http://gawker.com/#!5777460/fox-news-publishes-fake-exclusive-about-discovery-of-alien-life)

Fox News has a super-exciting article today: "Exclusive: NASA Scientist claims Evidence of Alien Life on Meteorite." OMG, aliens exist! Except this NASA scientist has been claiming to have evidence of alien life on meteorites for years.

[StanUpshaw]

Christ.

There's already a thread for that. (http://www.ronfez.net/forums/showthread.php?t=27099)

Fucking broken record. It's as bad as WF's immigrant obsession.

There is never enough Fox News hate on a message board.

Ever.

not to mention it fits here fine too

They are going to need more than just evedence.

They are going to need evidence too.
