False clues it would appear'
(in part)
Well, the temperature of space is, at its coldest, just the temperature of the leftover glow from the Big Bang. This radiation, known as the
Cosmic Microwave Background, bathes the entire Universe in a temperature of only 2.7 Kelvin. That's less than 3 degrees above absolute zero, or -455 degrees Fahrenheit! But there's also -- literally -- no pressure in space. So, what happens? Who wins? Does the water freeze or boil?
Oddly enough, the answer is
first one, and
then the other! It turns out that having a pressure vacuum will cause the water to boil almost instantly. In other words, the effect of boiling is much, much faster than the effect of freezing.
But the story doesn't end there. Once the water has boiled, we now have some isolated water molecules in a gaseous state, but a very, very cold environment! These tiny water vapor droplets now immediately freeze (or, technically,
desublimate), and become ice crystals.

When are you people ever going to give the right answer to anything? lol
