Sorry BMA .. but science is at a mere beginning in understanding how things work .. of what energies exist .. of what the universe is composed of. All questions are open to many possible answers. The speed of light for instance .. so fast per second, right? But time slows as gravity increases, or vice versa, I can't remember which right now. So .. in the space between galaxies where there is no gravity, what clock does time run at? How fast is a 'second'? Of course you will have people tell you such and such and this and that .. but they're just guessing .. probably they haven't even considered he aspect of the changing speed of time in relation to the speed of light .. so how do we know anything/ Here's something for you.

The problem with water in space is that it would take atmospheric pressure to prevent it from sublimating directly to space and it would take relatively high temperatures to keep it in liquid form to allow for the time needed for the dissolved solids in the water to form around the molecule involved in the experiment. Space is a Cold, Pressureless, near void in which water molecules can only survive as Ice (cold) or individual molecules (pressureless) or in the form of hydrates. The more Water molecules you bring together in space, the best you can form is a comet of increasing size. It takes the mass of a planet, proxcimity to a star (0.7 - 1.3AU or so) for warmth and atmospheric pressure to maintain liquid water at the surface. Now what you propose could be happening to a small extent on some of the distant moons that may have liquid oceans but not to the extent of forming planetary bodies.
Explanation: Some features of HH-34 are understood -- some are not. At the core of Herbig-Haro 34 lies a seemingly typical young star. This star, though, somehow ejects energetic "bullets" of high-energy particles, appearing as red streaks toward the lower right of the this image. Astronomers speculate that a burst of these particles might rebound when gas from a disk surrounding the star momentarily collapses onto the star. Visible near the end of each light-year long jet is a glowing cap. HH-34 lies about 1500 light-years away in the Orion Nebula star-forming region. The cause of the large arc of gas on the upper left known as the waterfall remains unexplained.
