Reference; http://www.upi.com/Science_News/2014/09/25/Water-in-Earths-oceans-older-than-the-sun/4441411674525/ Excerpt; A new study suggests as much as a third of Earth's ocean water was likely formed prior to the birth of the sun and sourced from deep space ice. Very fascinating...perhaps water just about everywhere...
Wow, I guess the Universe isn't as dry as I thought. Water, water everywhere including drops to drink. I like it.
Much of the water on Earth has come from comets and that it is so old adds to the case. But, I understand that we, too, are made of many atoms which are ancient, and older than the Sun, too.
the sun came first...then the planets used the gravity to form their orbits...80 % of the water on earth is below ground...and also there is one moon and saturn thats has water on its surface..its a small moon just about 300 miles in diameter but still bigger than most of the 60+ moons that orbit Saturn...
We and all elements above Hydrogen are, as Carl Sagan once said, "We're made of star stuff". The product of first generation stars that fused hydrogen atoms into more complex elements. Hydrogen is still the most common known element in the Universe, about 75% of its normal matter. The ESA's Rosetta comet probe should yield some interesting findings on this subject: http://sci.esa.int/rosetta/14615-comet-67p/
Water has a spectral line of around 557 GHz, and a satellite was launched in the late 20th Century to determine the abundance of water in the Universe, or at least targeted parts of it using the sensors on the satellite. The result was hit and miss, basically that the water abundance is very variable.
Gee Maybe water would literally fall out of the sky, in California Does It Still Count As Rain When It Is From an Asteroid ? Just more unanswered questions. Moi r > g No
If water exists in many areas, and the organic building blocks of life have been distributed, then all we need is some time and a good incubator and living organisms might be omnipresent...with many of them evolving to intelligent species...
I'll guess most water is connected to objects like planets, moons, comets, etc. and not necessarily detectable from long distances...maybe from evaporation...
A possibility and most certainly a logical idea, but one that remains to be proven. We've searched for decades now and also tried to make life ourselves. So far, not luck.
Life, depending on how it is defined, can take thousands, millions or billions of years to develop. Regarding our searches, you notice the discoveries are getting more interesting as our technology allows us to advance our studies. Theories and predictions exist because we don't have the technology to challenge them but we have more information every day. Beyond technology we also don't have the funding or are unwilling to fund...this is probably the biggest roadblock to achieving more sooner...
Depending on how it is defined? Please explain. Do you consider amino acids life because I do not. Yes, life may take a billion or so years to develop naturally. Best evidence seems to indicate life for came to Earth 3.8 billion years ago. Since the Earth is about 4.6 Billion years old, the one example we have shows life took 0.8 billion years to develop. http://www.bbc.co.uk/nature/history_of_the_earth Obviously artificial means shouldn't take as long. Another thing to consider is that our solar system is located in the outer reaches of the galaxy. The inner stars are billions of years older. If we've evolved from tree-living simians into space-faring humans in 2 million years, think of where we could be at 50 million years or a Billion. The inner stars are not only more plentiful, but being older, offer the idea that, if there was life around those stars, they'd be older too. Ergo, they'd more likely not only be more advanced than us, but we should be able to detect signs of intelligent life from those inner systems as they developed. http://www.sci-news.com/astronomy/science-milky-way-galaxy-01704.html
Even the sun's atoms are older than the sun In fact, most if not all of the solar system is made up of elements and compounds that originated at one point from the supernova of one of those first hot, giant, short-lived stars that formed post The Big One..
The idea of water, and life, on other planets prompted me to make a poll thread about it: http://www.politicalforum.com/opinion-polls/375923-if-life-discovered-other-planets.html
Life...a single-cell organism or multi-celled like Oprah? Regarding SETI...Earthlings have only been 'detectable' for what...100 years? Look around us, with continued wars, global climate issues, nuclear weapons, etc. the huge question is how long can we survive? At the rate we're going we'll annihilate ourselves in the next 100 years! So someone searching for extraterrestrial life must be searching during the very small time that we are available, that we are detectable...let's say 500 years on a scale of 1-50 million years? Perhaps during the next million years mankind might rise and fall 100 times? IMO, unless we can figure out how to manipulate time, all intelligent life everywhere are in the same boat as us...stuck on their respective rock. I don't buy the science fiction many of us believe mirrors reality...
Bacteria would even suffice. Any organism capable of self-replication would definitely be part of the answer. Since some computer programs can self-replicate, that brings up some interesting questions, but without computers they cannot do it. I'm talking about self-replication in nature, unassisted.
The natural dangers are the greatest, I feel. The sun looks at us the wrong way, we take a dive back into an Ice Age. A large enough piece of space debris slams into us, we get something even worse.
The Sun is relatively stable. Natural shifts of heating and cooling are prett predictable. Being hit by a large rock, even if we see it a year in advance, is pretty much a (*)(*)(*)(*)ed situtation for us. Same goes if a star supernova too close to us, say within a 100 light years, it can (*)(*)(*)(*) us up too. The closer it is the worse the results of gamma radiation.
It is supposed that water was delivered to Earth and Mars by the impact of Millions upon Millions of Ort Cloud Comets as comets are basically giant dirty ice balls. Mars had vast Oceans at one time but when Mars lost it's EM Field due to the cooling and slowing down then haulting Martian Liquid Metal Core....Solar and Cosmic Radiation split Water Molecules...H20 into Hydrogen and Oxygen gases and these were lost to space....but Mars may indeed still have large amounts of water left frozen under the soil.

We just got "lucky." http://www.newscientist.com/article/...l#.U1_tzSm9Kc2 Metabolic processes that underpin life on Earth have arisen spontaneously outside of cells. The serendipitous finding, that metabolism the cascade of reactions in all cells that provides them with the raw materials they need to survive can happen in such simple conditions provides fresh insights into how the first life formed. It also suggests that the complex processes needed for life may have surprisingly humble origins. "People have said that these pathways look so complex they couldn't form by environmental chemistry alone," says Markus Ralser at the University of Cambridge who supervised the research. But his findings suggest that many of these reactions could have occurred spontaneously in Earth's early oceans, catalysed by metal ions rather than the enzymes that drive them in cells today.
Truth is, man is man's worst enemy. Truth itself is the savior for us all, if we will see and hear it, then act accordingly.
