Space opera is a subgenre of science fiction that emphasizes romantic, often melodramatic adventure, set mainly or entirely in outer space, usually involving conflict between opponents possessing advanced technologies and abilities. The term has no relation to music and it is analogous to "soap opera". Perhaps the most significant trait of space opera is that settings, characters, battles, powers, and themes tend to be very large-scale. Sometimes the term space opera is used pejoratively to science fiction often combined with mythological themes, but its meaning can differ, often describing a particular science fiction genre without any value judgement.
