Some are really interested in stuff like this and others are like "ok, whats the point?" I would love to work for NASA just to sit around all day looking at new discoveries.
This isnt really new news. Most astonomers have had a good hunch that there was water on Enceladus, this find is just the smoking gun. http://www.nineplanets.org/enceladus.html BTW, liquid water can exist in temperatures below 0*C(32*F), if/when the air pressure is lower than a standard atmosphere on Earth.
