"Weight vs Mass? Is there a difference?"
Does anything really have weight in space? Doesn’t weight have to have gravitational properties surrounding it.

Good catch. And you’re right. The title should have been: NASA accurately calculates Milky Way’s mass.
An error like that kinda makes you wonder about the rest of the article.
Mass.
You're right. ESA got it right; Fox screwed it up. Never let a reporter talk about science.
The WEIGHT of something depends on how close it is to something ELSE (like a planet or star). The MASS of something is a measure of how much material is in it, and doesn't change because of location.
LOL. GREAT catch. Objects in space have a fixed mass but their weight varies with gravitational attraction, i.e. distance to other objects. You get a gold star for catching that right off the bat.
