O2+ on a moon of Saturn

 I have atattched the URL of a story of Oxygen detected on the moon Dione by the Cassini spacecraft years ago.
It is not enough to support a Na'vi, but the mere presence of it is really cool.

Interesting, also nice to see Cassini is still gathering data. So many interesting things in the solar system

Oh...everybody thinks this is strange, but it is not strange at all. Oxygen is literally everywhere in the universe - most rocks are silicon dioxide and when they are melted some of the molecules break down into silicon and oxygen. There is also some oxygen around Jupiter's moons.

I completely agree that oxygen of a form can be on many of these moons. After all, titan is believed to have hydrogen seas... and IO around Jupiter is believed to be ice.

I've been studying HVAC for refrigeration and the like and there is a temp and pressure thing for the cooling agents and I have learned that water at sea-level boils at 212F but in Denver will boil at closer to 180ish degrees... and the less pressure, the lower the boiling temp... IE: in space even though it is freezing, most water vapor that is out there, and it IS out there (Think Ort Cloud). It is likely also one of the most abundant substance in space.

Water is two hydrogen, one oxygen... so yes, oxygen is everywhere.
