depends on the context
(Update from another answerer): Depends on the context? I guess the helpfulness of an answer depends on the.... content, which that answer severely lacked. To actually ANSWER the question, here goes: If you Google it, or look it up on history.NASA.gov which refers to the Chicago Manual of Style, NASA insists that universe not be capitalized. Technically, though, it fits all of the requirements to be a proper noun, and therefore some people do capitalize it and (technically, again) they can't be penalized for that. To sum up, those that use this term the most in a professional sense (NASA and her partners) prefer not to capitalize it, while those that want to give emphasis to the importance of the word and/or show that they know the technical definition of a proper noun will capitalize universe.
