Water, water everywhere…. #water #life

… Even where we didn’t think it should be

When the Earth formed it could not have had water. It was simply too hot at that part of the early system. Instead water probably condensed on comets and the general consensus is that water was brought to Earth through collisions with these comets. However new research adds another dimension. The water we have now may have been around long before the solar system was even formed.

This means that come of the water molecules in your drinking glass were created more than 4.5 billion years— even older than the sun itself. In a study published Thursday in Science, researchers say the distinct chemical signature of the water on Earth and throughout the solar system could occur only if some of that water formed before the swirling disk of dust and gas gave birth to the planets, moons, comets and asteroids. This primordial water makes up 30% to 50% of the water on Earth.

This finding suggests that water, a key ingredient of life, may be common in young planetary systems across the universe. Think about that next time you turn on your facet.

  1. Can more comments carrying water come hit our oceans? Our Earth needs it since we are have been recycling water to keep re-using. Water keeps our society living and to have more of it would be great.

  2. It amazes me the fact that water is older than the Sun itself, and makes me wonder that if water came from the collisions, how big were they in order to have such big oceans on the planet.

  3. This discovery makes me wonder if there is a difference in the water that came from interstellar space and the water that did not. Also, I would like to know how the water on Earth was formed if it did not come from outer space. If water is common around the galaxy, than there is a bigger possibility of life existing elsewhere than we once believed. Maybe a comet’s whole purpose is to carry water from one place to another to help create life.

  4. I remember hearing about this last week in the news. I found it interesting because the Earth is about 4.6 billion years old and now scientists have found that water is older than that?! I’m not sure exactly how this could be but I find it very interesting that the main liquid we need for survival, found on planet Earth, is older than Earth itself!!!

  5. This find could completely change the way of thinking about our solar system. Yet there is still so much more to learn about our universe and how it was formed. Quite mind boggling to think about it all.

  6. It’s pretty cool that some of the earths water came from interstellar space, and that the deuterium is like that hydrogen water but with an extra neutron. So if earth was formed in interstellar space then there has to be life in space.

  7. Water that’s older than older than the earth itself, amazing! The conclusion that a significant portion of water on the earth has interstellar origins adds the possibilities and questions of what exists throughout the galaxy. Can’t wait to learn more!

  8. I find this article very interesting. I also find it very interesting that the sun didn’t heat up the water molecules and turn them into steam. This article makes me wonder what the water would look like in a galaxy with out a planets gravity to hold it in place. Very interesting.

  9. I really wish we had clean drinking and bathing water for everyone on Earth if water is this prominent throughout the universe. It’s really enchanting to think about all this clear liquid (if it is like that in space too) floating around creating galaxies and sending comet packages of water to planets.
