>language of certainty ("has moons") I don't read it that way. This is a science topic, I think the phrase "Jupiter, which has 79" does NOT mean "no more than 79" but does mean at least 79 that we know. I don't think it signals a lack of humility. I think it is just shorthand for "Jupiter has 79 moons, that we have verified". Since this is in the context of discovering more moons that we hadn't seen before, I don't think the extra verbiage is necessary and is implied. Of course we are in the process of discovering more moons. That's what the entire article is about.
