Space operas

Space opera is a subgenre of science fiction that emphasizes space warfare, melodramatic adventure, interplanetary battles, as well as chivalric romance, and often risk-taking. Set mainly or entirely in outer space, it usually involves conflict between opponents possessing advanced abilities, futuristic weapons, and other sophisticated technology. The term has no relation to music but is instead a play on the terms "soap opera" and "horse opera", the latter of which was coined during the 1930s to indicate clichéd and formulaic Western movies. Space operas emerged in the 1930s and they continue to be produced in literature, film, comics, and video games.

Notable space opera novels include the Foundation series (1942–1999) by Isaac Asimov, the Lensman series (1948-1954) by E. E. Smith and the Ender's Game series (1985–present) by Orson Scott Card. An early notable space opera film was Flash Gordon (1936–present) created by Alex Raymond. In the late 1970s, the Star Wars franchise (1977–present) created by George Lucas brought a great deal of attention to the subgenre.

Space opera is defined as an adventure science-fiction story.

The term "space opera" was coined in 1941 by fan writer and author Wilson Tucker as a pejorative term in an article in issue 36 of science fiction fanzine Le Zombie. At the time, serial radio dramas in the United States had become popularly known as soap operas because many were sponsored by soap manufacturers. Tucker defined space opera as the science fiction equivalent: a "hacky, grinding, stinking, outworn, spaceship yarn". Even earlier, the term horse opera had come into use as a term for Western films. In fact, some fans and critics have noted that the plots of space operas have sometimes been taken from horse operas and simply translated into an outer space environment, as famously parodied on the back cover of the first issue of Galaxy Science Fiction. Still, during the late 1920s and early 1930s, when the stories were printed in science-fiction magazines, the stories were often referred to as "super-science epics".
