Building block of life found on comet

The amino acid glycine, a fundamental building block of proteins, has been found in a comet for the first time, bolstering the theory that raw ingredients of life arrived on Earth from outer space, scientists said on Monday.

Microscopic traces of glycine were discovered in a sample of particles retrieved from the tail of comet Wild 2 by the NASA spacecraft Stardust deep in the solar system some 242 million miles (390 million km) from Earth, in January 2004.

Samples of gas and dust collected on a small dish lined with a super-fluffy material called aerogel were returned to Earth two years later in a canister that detached from the spacecraft and landed by parachute in the Utah desert...

...The initial detection of glycine, the most common of 20 amino acids in proteins on Earth, was reported last year, but it took time for scientists to confirm that the compound in question was extraterrestrial in origin.

"We couldn't be sure it wasn't from the manufacturing or the handling of the spacecraft," said astrobiologist Jamie Elsila...

...She presented the findings, accepted for publication in the journal Meteoritics and Planetary Science, to a meeting of the American Chemical Society in Washington, D.C., this week.

"We've seen amino acids in meteorites before, but this is the first time it's been detected in a comet," she said...

...The latest findings add credence to the notion that extraterrestrial objects such as meteorites and comets may have seeded ancient Earth, and other planets, with the raw materials of life that formed elsewhere in the cosmos.

"The discovery of glycine in a comet supports the idea that the fundamental building blocks of life are prevalent in space, and strengthens the argument that life in the universe may be common rather than rare,"

Oh, it wasn’t a big bang, it was a meteor shower. I’m convinced.

Let them find another water planet like Earth and then I’ll be impressed.

when they had their budget plea last week a FReeper recommend they find “evidence of life” out there somewhere

And how many amino acids are needed for ONE protein?

The Kepler probe is searching for canditates right now to check on with probes that’ll eventually detect oxygen and other evidences of life.

Why? There's water all over the solar system, including on Mars. Probably all over the universe.

Surely you're not so illiterate that you think that scientists believe life began in the Big Bang...

Party at GG’s... Anyone bringing the chips and dip?

Unfortunately, I will have to attend tomorrow evening as I’m currently busy attempting to build a dolphin with some spare amino acid I found in the woodshed. So far all I have is a dorsal fin but all in good time...

By the way... it’s BYOB (Bring your own brain) so I doubt any Evolutionists will attend.

“Surely you’re not so illiterate...”

You, my friend are probably the rudest person I’ve met on this site... to assume that WestwardHo is illiterate without ever having met his parents is a little more than presumptuous. If you have no proof his parents were unmarried when he was conceived then you should keep your accusations to yourself!

My word!!!

Straining at gnats? Those are huge compared to amino acids. Good luck with that dolphin :o)

Why would you assume that? Honestly, it amazes me the things that call for a sarc tag around here. Yep... just spendin’ an evenin’ joshin’ with the Evo’s.

Luckily, I won’t be eating it any time soon... not that there’s anything wrong with that <{{><

I don’t quite get it.

Somehow the “humanists” have come to the conclusion that if life exists somewhere other than earth - it proves there is no God. Don’t they understand that most of us that believe in a Supreme Being - believe that the Supreme Being is quite capable of creating life ANYWHERE, and bringing it to earth ANY WAY.

Human life, for example is believed to be divine creation. That belief is not diminished by the knowledge that the creator chooses to use sexual union to facilitate that creation.

Odd isn’t it, how the humanists can find the tiniest microscopic precursor of life to be of universe altering significance - but an actual human embryo to be less than nothing.

Nah, that's just the bio-gunk left over from Harry Stamper (aka Bruce Willis) after he nuked the asteroid.

Evos are the single most sarcasm and humor challenged group of people I’ve ever met.
