    Actually, it is all probably in vapor form. It's hard to make ices in most of space, since it is rare that molecules come together to make a crystall.

    Water will not exist as a liquid in space, basically for the reasons you cite (plus, with effectively zero pressure, the water will just evaporte pretty quickly). But water vapor can exist inside the clouds of other gases, particular atomic hydrogen. Water, being such a great absorber and emitter of radiation, is really easy to spot, so we talk about it a lot.
