WAIT? WATER ON EARTH IS, AT LEAST, A MILLION YEARS OLDER THAN THE SUN

A new study in the journal Science, published September 26, 2014, suggests that much of the water on Earth and throughout our solar system likely originated as ices that formed in interstellar space. If so, it means that water may be more widespread in planetary systems than previously thought.

The researchers’ work addresses a debate about just how far back in galactic history our planet and our solar system’s water formed. Were the molecules in comet ices and terrestrial oceans born with the system itself—in the planet-forming disk of dust and gas that circled the young sun 4.6 billion years ago? Or did the water originate even earlier, in the cold, ancient molecular cloud that spawned the sun and that planet-forming disk?

The new research suggests that between 30 and 50 percent came from a molecular cloud. That would make it roughly a million years older than the solar system.

To arrive at that estimate, the team – led by L. Ilsedore Cleeves from the University of Michigan – utilized a known ratio between two slightly different varieties of water – the common kind and a heavier version, made with a chemical element known as heavy hydrogen, or deuterium. It’s a long-time mystery in astronomy that, today, comets and Earth’s oceans hold particular ratios ofheavy water — mysteriously higher ratios than our sun contains. Where did the heavy water come from?

The difference in the masses of ordinary water and heavy water lead to subtle differences in their behavior during chemical reactions. These differences can help tell scientists about the conditions under which the molecules formed. Cleeves and her colleagues constructed a detailed model of the chemical processes creating water in a protoplanetary (planet-forming) disk, like that from which our Earth and solar system was born. They found that they could not account for the amount of deuterium in Earth’s oceans or in comets via the processes in the planet-forming disk. They conclude that water on Earth must have come from interstellar space. Get more details about the study in this great post in Science.

 

All life on Earth depends on water. Understanding when Earth’s water came to be – and where it came from – can help scientists estimate how common water might be throughout the galaxy. Conel Alexander of the Carnegie Institution of Science is a member of the research team. He said:

Our findings show that a significant fraction of our solar system’s water, the most-fundamental ingredient to fostering life, is older than the sun, which indicates that abundant, organic-rich interstellar ices should probably be found in all young planetary systems.

Bottom line: Up to half of the water on Earth is likely older than the solar system itself, astronomers say. Much of the water on Earth and throughout our solar system likely originated as ices that formed in interstellar space.

  1. Well dear grandma Star Yazmin,the newest discovery among scientists is that time doesn’t exist, it’s only us humans that use time for measuring, but if it’s true I don’t know ☺😊☺😊😆😆😆 and to be honest I don’t care about that ☺😊😍😍

  2. Maybe such happens, there could also pass a star near our solar system and then there will be disturbance in the planets orbit 💫 so they get new orbit 💫 and maybe there will come a new planet 🌍 in orbit in our solar system, or the opposite thing, maybe time will tell 😊😄🔭🔭🔭

  3. This book explains how a large rouge comet made the solar system what it is today. What is Jupiter was the head of the comment and Saturn was the tail. It took several different passes over many millenia. At some point the planet Tiamat, that translates as “Planet of water” was impacted. It became the asteroid belt and Earth. If you remove all the water from Earth you will find that a large section of the Pacific Ocean land mass (that is what should be under the water) is missing like someone took a bite out of it.

    Mars was originally in the orbit that Earth now occupies, which is how it lost its atmosphere during its relocation.

    The book further explains why each planet is located where it is due to Standing Wave Nodes originating from the Sun; look up ‘Gravity is a push’ or ‘Pushing Gravity’.

  4. NOT LIKELY HUMAN.THE REALITY IS THAT YOUR SOLAR SYSTEM IS NOT WAT YOU BELIEVE IT TO BE.BUT THE THE PLANET EARTH,TIAMAT,HAS ALWAYS BEEN IN THE SOLAR SYSTEM AT THE CORRECT POINT SO WATER CAN FORM AND CREATE SMALL ORGANISMS THAT EVOLVED IN TO OTHER COMPLEX FORMS,BUT YOUR SUN HUMANS IS OLDER THEN THE EARTH.NOT THE OTHER WAY ROUND

  5. It`s not my idea, It has been written down by a host of people about the history of the universe. Mainly Zecharhia Sitchin but also Gerald Clark,Michael Tellinger,Wes Penre,Robert Morning Sky,Stephan Greer, Sasha Alex Lessin and more !

  6. It was in between Mars and Jupiter !. Then it collided twice with the moons of a much larger planet and tore it in half. The half we call earth was knocked over to our present orbit. Then the remaining fragments formed the asteroid belt !

    • But isn’t it weird that it was neither caught by the gravity of Jupiter Or Mars, nor caught by the sun? Just shifted from its ORIGINAL place & got a new orbit, about 550 million km away from its original spot?
      Point 2- How come, of 2 parts, one was so big & perfectly spherical, while the other part was crushed into million parts, the largest being few km big??

      Isn’t it a point to ponder?

  7. Fantastic, maybe earth was created another place in our galaxy, that could be possible ☺😊 earth could have orbited another sun, which slowly burned out, and then the weaker gravity couldn’t hold earth in orbit so it drifted away, and then after long time was caught in by our present sun ☺😊🙌🔭💥🎆🎇
