Solar System's Water Is Older Than the Sun
astroengine writes Next time you're swimming in the ocean, consider this: part of the water is older than the sun. So concludes a team of scientists who ran computer models comparing the ratios of hydrogen isotopes over time. Taking into account new insights that the solar nebula had less ionizing radiation than previously thought, the models show that at least some of the water found in the ocean, as well as in comets, meteorites and on the moon, predate the sun's birth.
For anything in the solar system to be YOUNGER than the sun, it would have to be MADE by the sun, or as a byproduct of the sun achieving fusion. Our planet is younger than the sun itself, but the elements that comprise it are much, much older.
So... light first, then water, then the sun.
I guess that's one for the YEC's.
Though, I'm still going with "allegory" as an OEC...

1 In the beginning God created the heavens and the earth. 2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
3 And God said, “Let there be light,” and there was light. 4 God saw that the light was good, and he separated the light from the darkness. 5 God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning—the first day.
6 And God said, “Let there be a vault between the waters to separate water from water.” 7 So God made the vault and separated the water under the vault from the water above it. And it was so. 8 God called the vault “sky.” And there was evening, and there was morning—the second day.
This means that at least a percentage of the water on this planet is of alien origin.
Wait, everything is of alien origin.
Water is made and destroyed daily. Just because you find old hydrogen isotopes in the water doesn't mean that they were part of water molecules even last week!
If our solar systems water is older than the sun why does my bottle of Fiji expire in a year? :)
Turn out, all our water is greywater .
Shouldn't *all* water in the solar system be older than the Sun? Pretty much everything heavier than Lithium should be older than the Sun, except the results of radioactive decay from elements that, again, were older than the Sun.

of almost all matter that exists anywhere?
Stars create water when they blow up, super nova etc. Our sun does NOT create water (yet). Perhaps in 4 billion years when our sun exhausts hydrogen and helium...it might.
Our solar system is for the most part comprised of mater created 4.5 billion years ago or earlier. Perhaps a supernova some 6-10 billion years go left hydrogen, helium, all the periodic elements we see today. Rocks, asteroids, meteors, all remnants of whatever happened before 4.5 billion years ago as our solar system formed.
My guess, is *most* as in 90%+ water came from long ago, oort cloud gets disturbed by a passing star, next thing you know our planets get chunks of ice for a million years or so. And how earth got most of its water, from space mater as our planets formed, then later via meteors and comets.
What for did this "water" exist in before the sun was born.....?
If it's just hydrogen, or isotopes thereof, that does not count.

About time science catches up with the Word of God.
Genesis 1 King James Version (KJV)
1 In the beginning God created the heaven and the earth.
2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
3 And God said, Let there be light: and there was light.
I believe that they are only considering the water molecules: the hydrogen atoms which make up water will be as old as the Big Bang. However since there are ice-based comets out there I hardly find it surprising that there was water in the solar system before the sun formed. Aren't the comets supposed to be the left over debris from the formation of the sun and planets? So this result seems to be just confirmation what we already knew.
The heavy elements on our planet and in your body were creation via fusion in another star, which has already long since died, exploded, and been recycled.
We can do better than that. Based on the current ratio of Uranium-235 and 238 which are created in roughly equal quantities by a supernova we can date the super nova preceding the solar system to about 6 billion years ago. It's also interesting to note that had intelligent life evolved a billion or more years earlier than it did that the uranium ore we dig out of the ground would be weapon's grade without any complex enrichment process required. So there might be a limit on intelligent life evolving too soon after the formation of a planet.
I'm not sure if I will ever swim in the ocean. In a sea maybe and in a lake for sure.
From TFA, which quotes the original author:
“The finding ... makes it quite hard for these regions in the disk to synthesize any new molecules. This was an 'aha' moment for us -- without any new water creation the only place these ices could have come from was the chemically rich interstellar gas out of which the solar system formed originally,” Cleeves wrote in an email to Discovery News.
“It's remarkable that these ices survived the entire process of stellar birth,” she added.
(Bold mine)

I heard the human body is 90% water, so how come I'm not older than the solar system?
Fish fuck in it.
Lost at C:>. Found at C.
Or the Hydrogen and oxygen making it up?
I'd venture a guess that, what with water molecules continually dissasotiating into H+ and OH- ions and then recombining, most of our water is quite young.
Have gnu, will travel.
The key part: "darkness was over the surface of the deep, and the spirit was hovering over the waters. And God said, “Let there be light,” and there was light." I'm the last person to push theology, and not remotely christian, but that's... poetically pretty.
Yes, the waters were here long before us, before the earth, before (our) star. I don't have to agree with anyone's religious tales to appreciate and share a sense of wonder at the bigness and oldness of it all.
I think not...(*poof*)
*every* *damn* *thing* can be traced back to alien visitors. Because puny humans could never have accomplished anything without them.
They never answer my question of who setup the ancient astronauts? If they could evolve to their functional status as spacefaring beings, couldn't humans (eventually)? Otherwise, is it ancient astronauts all the way down.
My wife cannot seem to walk away from those shows! Even though she doesn't believe them.
The main component of wood is cellulose, a polysaccharide consisting of building blocks of six carbon atoms, ten hydrogens and five oxygen atoms.
Take one of those C6H10O5 building blocks an burn it completely with 6 O2 molecules, and you get 6 CO2 molecules and 5 brand-spanking new water molecules.
Of course real wood fires release other byproducts as well, carbon monoxide and soot, which are particles of mostly amorphous carbon. But water is definitely a byproduct of burning, just as it is a byproduct of respiration by organisms.

Hmm, I guess those Aliens up there have to drink something.
But seriously, we have found water on the moon?
Be seeing you...
Literally
According to the Bible, that's right:
Genesis 1
1 In the beginning God created the heavens and the earth.
2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
3 And God said, “Let there be light,” and there was light.
It is interesting that you mention this point about the half-life of Uranium ore. The inverse claim that you could make would be that there longer it takes intelligent life to evolve after the formation of a planet, the more difficult it will be for them to create nuclear weapons, as enrichment will become more and more costly/ time consuming as each successive billion years pass.
Consequently, the the mean longevity of a civilization on an 'old' world would be ever so slightly increased in Drake's equation, as nuclear weapons would be less likely to end it. If you are targeting SETI searches, aim for the older planets in the universe?
Galactic actuarial tables for nuclear fallout insurance drops your rates after you turn ten billion...
HA! I just wasted some of your bandwidth with a frivolous sig!
..only an emptiness. formless. ...a dark endless waste of water..
Check it out.
So, plenty of the water in our solar system could be younger than the sun precisely because it was made by the sun.
Why buy a solar system, when the sun is not around to heat the water !!! This makes no sence.
Ancient man felt insignificant and believed gods created the earth. Science has an explanation for how the universe came into being but not from where what made it came from or what over 90% of it is. As a Christian, I say God. But keep trying guys, everything you say makes sense and I await your next discovery. However celestial objects came into being, the photos are awesome.
I to love the poetry of the Bible.
For God to exist, he doesn't have to have created the universe literally... I'm not quite sure what that means.
Pretty much any element heavier than helium in our solar system pre-dates the sun. All of the oxygen in our solar system was produced by other stars.
On that show and others like it, *everything* on this planet is a result of meddling by visitors from outer space. Every ridiculous claim proffered, like George Washington cross the Delaware on the advice of some little green man, or that Bigfoot is an on-going genetic experiment by aliens, is preceded by the phrase "Ancient Astronaut theorists believe that...".
A book written thousands of years ago states it was this way. Its called the bible.
The water molecules may come and go, but if most of the water now available to us was locked up as water ice and not exposed to solar neutron flux the isotope rations of hydrogen would be less than what is expected if all of the water were exposed to it through out the entire time of its presence in the solar nebula, that is, if the water arrived in the vicinity of the sun at the same time it was formed. I think that the argument is that isotope ratios indicate that according to a model of the expected isotope ratios that the water had to exist before the sun ignited. The starting of the solar neutron flux did not have time to produce the isotope rations expected from the model, therefore. So, it is a model, a prediction and a contradiction of the prediction, isotope ratios have to be less than expected because the water ice existed before the sun and the hydrogen in it was not subjected to solar neuron flux, or any nearby source of neutrons.
Read Genesis 1:2-3. Interesting how God explained through Moses that prior to the Light (sun) he hovered over the waters... Just remember the One who created the heavens and the earth inspired men to write the bible. Science will always prove the bible. And no, the earth is not 7000 years old, and the bible does not say it is!!!
