DNA building blocks confirmed as E.T. origin

reply to post by yeahright


George Cooper, a chemist at NASA Ames Research Center, told SPACE.com. "One function of this cycle is respiration, when organisms give off carbon dioxide."

"It is always exciting to find extraterrestrial and ancient 4.6 billion-year-old organic compounds that might have had a role in early life," Cooper added.

"Finding nucleobase compounds not typically found in Earth's biochemistry strongly supports an extraterrestrial origin," Cleaves said.

"At the start of this project, it looked like the nucleobases in these meteorites were terrestrial contamination — these results were a very big surprise for me," study lead author Michael Callahan, an analytical chemist and astrobiologist at NASA Goddard Space Flight Center, told SPACE.com.

The components of DNA have now been confirmed to exist in extraterrestrial meteorites, researchers announced.

A different team of scientists also discovered a number of molecules linked with a vital ancient biological process, adding weight to the idea that the earliest forms of life on Earth may have been made up in part from materials delivered to Earth the planet by from space.

Past research had revealed a range of building blocks of life in meteorites, such as the amino acids that make up proteins. Space rocks just like these may have been a vital source of the organic compounds that gave rise to life on Earth.

Investigators have also found nucleobases, key ingredients of DNA, in meteorites before. However, it has been very difficult to prove that these molecules are not contamination from sources on Earth. [5 Bold Claims of Alien Life]

"People have been finding nucleobases in meteorites for about 50 years now, and have been trying to figure out if they are of biological origin or not," study co-author Jim Cleaves, a chemist at the Carnegie Institution of Washington, told SPACE.com.

To help confirm if any nucleobases seen in meteoriteswere of extraterrestrial origin, scientists used the latest scientific analysis techniques on samples from a dozen meteorites — 11 organic-rich meteorites called carbonaceous chondrites and one ureilite, a very rare type of meteorite with a different chemical composition. This was the first time all but two of these meteorites had been analyzed for nucleobases.

The analytical techniques probed the mass and other features of the molecules to identify the presence of extraterrestrial nucleobases and see that they apparently did not come from the surrounding area.

Although its not an organisim it is the building blocks in the form of amino acids,let the reader think for themselves if they did form an organisim that broke down due to cosmic radiation or not
It strengthens the theory that life may have been seeded here from such material.

Ill change the Title btw.

Well, it may just look like Star Trek out there after all. I don't know about all the technology, but life being the rule and not the exception is something I think we may find to be a universal constant.

ok "headline grabbed modified" better ?

what he said

It doesn't matter if it's out there, it's here right now, look in the mirror. that should tell you in this infinite universe, that OBVIOUSLY there are more lifeforms because of the simple fact, we are here now.

There are only so many chemicals that comprise our universe. Of course we are made from the same stuff. Aint nuttin new under the sun.

Yes - and my interest is piqued in this regard a shade more than normal because of an "insider tip" type of thread posted in late July. I know that 99.99% of these turn out to be nothing, but I am watching with interest nonetheless.

Sorry to pour water on your parade, but nothing ,and i mean nothing is credable on Fox
news. If you have other sources you would do well to post them.

The universe is a really big place. In our exploration we've only just stepped out the front door and are still standing on the porch. Lets wait until we've at least explored the back yard before we say there is nothing there. The universe likes repeatition. Multiple suns, multiple planets, multiple asteroids. We already know this just from simple observation. If it repeated those steps in its creation why would it not repeat life?

I did have annother look its on space.com an information website about NASA.
scroll up a little and youll see the link

yes its that drip drip feed of enlightenment

Just to help hrmmm out a bit answering your concern, see the video below uploaded by NASA in the last day or so:



All the best,

Wow, with all these "multiples",im guessing the Universe must be female.

Chemicals yes, but these were protiens (amion acids) and nucleoids (the building blocks of DNA)
Which has not been addmitted as being of extra terestrial origin by "man" until now.

No, we don't know there is bacterial life. When you state that as if it is fact you drag us all down to your level of ignorance.

Whose level of ignorance?

The Claim: NASA Scientist Finds Alien Fossils in Meteorites

Original paper

Then we get this.

Evidence of Martian life dealt critical blow

So are we being dragged down to NASA's level of ignorance?

If you skim through the thread you'll see links to other media, including The Washington Post and Space.com

Hey - good call on the Headline edit - I gotta figure out how to do that. It would have come in handy yesterday.

Please don't misinterpret what I said. I didn't state, imply, or suggest there wasn't life elsewhere. What I said was, we haven't found it. When we do, I'm pretty sure we'll all hear about it because it will be a very big deal. Bacteria or otherwise.

Personally, I have no idea why the media reports what they report when they report it. What I do know is, there is yet to be confirmation of life anywhere off our little blue marble. I think it's likely there somewhere, but no, no proof yet.

There is a difference between life and the building blocks of life.

Too true brother.


Then again, if those blocks are there, you just need something to build them up, and with the vast amounts of planets that probably can harbor life I'm sure some got lucky, if not a lot got lucky!

I watched a documentary on C4 about what life may look like on a different planet ages ago, I think it had some influence from Hawkings, but they theorized whale like creatures could fly, and forna growing like mountains up in to the sky and what ever.

Another theory strange theory I've always wondered is...

Imagine a whale diving underwater. People often compare deep sea to space, It's a massive void with no air. Is it possible a creature comparable to a whale in characteristics, but more like a bird, could venture out of his home planets atmosphere and survive on a massive breath of what ever he's inhaling to stay alive, if he even is inhaling.
I'm not saying this happens, because it's crazy. But imagine if it was? How ridiculous would that be? Imagine a bloody space whale floating around eating rocks and what not.
