Can liquid oxygen occur naturally?

I was just wondering if liquid oxygen could occur naturally, on this or any other planet? We’ve found asteroids full of metals and minerals and such floating around in space, and it just occurred to me that it may be possible to find other things as well.

Update: Thank you all for the great comments! I didn't expect so many people to answer. This community is awesome!

The thing about oxygen is that it really really doesn’t want to stay as free atomic or molecular oxygen. It reacts with silicon to form silicates, which is to say rock, with metals to form metal oxides, with carbon to form CO or CO2, with hydrogen to form water… and there’s a *lot* of hydrogen in the universe!
