We find astronomical information very useful in learning about our own part of the universe. Space is home to lots of plasma physics, all planetary geology beyond sample size one, and high energy events we might find it difficult to re-create, like the big bang.

Even if in the end it's just pretty pictures (maybe you think every part of physics potentially relevant to engineers has been discovered), why don't space critics put the same heat on Hollwood? The real question here is why we spend billions on imaginary planets, but I've never heard it asked.
