Of course, sometimes exposition is necessary for expediency’s sake. But it should appear sparingly. A quick sentence noting some historical event or a common trait of an alien species is fine. After all, on that rare occasion, showing rather than telling would add far too much length to a story. If falling into this situation, remember to only include just the amount of exposition that is needed to move the story forward.
