About Space Opera

Space opera is a subgenre of science fiction and science fantasy that emphasizes epic outer space adventures set in a universe in which faster-than-light travel has become common. The plots often play out against a backdrop of space warfare, alien civilizations and galactic empires. The sub-genre is sometimes thought of as a futuristic homage to earlier adventure sagas, such as those found in mythology and chivalric romance. The term does not refer to opera music, but instead originally referred to the melodrama, scope, and formulaic stories of operas, much as used in "soap opera", a melodramatic domestic drama, and "horse opera", a 1930s phrase for a clichéd and formulaic Western film. Prototypes of space opera emerged in the early twentieth century, and the genre today enjoys great popularity in literature, film, comics, television, video games and board games.
