Signs of liquid water found on Enceladus

It is not impossible to have a vacuum. Although it is impossible to have an absolute vacuum. As MID has explained a vacuum is an absence of matter. You could try looking the word up in a dictionary, it's not difficult. If you take a glass flask, attach a pumd and remove all the gas, dust and every other bit of matter from inside that glass flask what you have is a vacuum. A vacuum is to matter what dark is to light. Now the reality is that you will never be able to remove every single atom and molecule from that glass flask. It will not an absolute vacuum, but it will be close enough as to mak... [More]

I could be wrong but isn't water the third most common element in space? Oh wait hydrogen is the most common helium is the second and oxygen is the third. Lets just say there is a lot of water out there.

Lets just say there is a lot of water out there. Well, water is actually a molecule, not an element. It has been known since the latter 1990s that the chemical processes that form water are rather common in the galaxy, and that water was abundant. I read long ago that studies of specific galactic regions indicated that water was the third most prevalent molecule in those regions observed. You're absolutely right. It certainly appears that th... [More]

Yes, what he said . . .

Space(even intergalactic space) is not totally devoid of matter. It is not an absolute vacuum but it is close. Very VERY close. Gregg, the point i was trying to make is that when liquid, such as water, boils into space it disperses so widely that space remains a vacuum (mainly down to space being so huge). That is why it is a vacuum. That is the answer to my question. Thanks! 'SPACE, the final frontier.' And further, correct me if I'm wrong, but it is not an absolute vacuum because the universe has boundaries? Or is it the universe has stopped expanding? Nope, nope! That flies in the face of c...

Posted 10 February 2010 - 11:46 PM Maybe someone can enlighten me. I don't understand how there can be water on anything in space without an atmosphere. Here on earth, water will boil at room temperature when placed in a vacuum. Now, if space is a vacuum, I believe water would just boil off. Also here on earth, the higher the altitude, the lower temerature is required for water to boil. Anyway, that's just my penny's worth. Odie I think Guardsman Bass best answered my question by saying that the water is shielded from space by ice or some other material. GreggK wanted to know where the water g... [More]

Scientist who know these things say that the 'atmosphere' of space is primarily Hydrogen and Helium where there is an atmosphere. The sun of our solar system is not Hydrogen or Helium, but Protium and Deuterium. Hydrogen and Helium come from that, but so does everything else; everything included. The production, combination, and recombination of elements will produce water at some point. On another scale, it will produce a tree, on another scale, a stone or a crystal.

I think Guardsman Bass best answered my question by saying that the water is shielded from space by ice or some other material. GreggK wanted to know where the water goes when it boils off. It goes into the atmosphere. I'll tell you of a little demonstration I did for a friend of mine. First of all, during my working years I was a commercial refrigeration technician for about 35 years. A friend was in my shop one day and I told him that I could boil water at room temperature. He laughed and said no way. I took a Mason jar and put about an inch of water in it. Then I soldered a fitting in the l... [More]
