What makes a science fiction story a space opera? Well, it needs to take place in space obviously, though not necessarily all of the time. Hanging out solely in an arcology on a climate-blasted Earth, or even in a domed city on Mars, doesn’t cut it. Actually, the more space the better; though there are certainly exceptions, a good space opera should span a galaxy or two, or at least a solar system. And an opera has to be grand and dramatic –battling empires, invading aliens, mysterious ancient technology, and grand, sweeping story arcs.
HERE are 55 science fiction stories from the last 70 years that make the cut.
