This does mean oceans on the satellites orbiting gas giants might be common place throughout the Universe:

All of the gas giants being discovered might have such moons which harbor life. Hopefully they will be able to detect satellites in the near future orbiting these exoplanets so we can get a better idea of how many are out there.

That was very interesting, there just may be water elsewhere in our galaxy, since our earth in becoming shorter on supply of water, other than sea water, we may in the future need to tap into those moons, that is if it is H20 and not some other liquid.
