Planetary romance is a subgenre of science fiction in which the bulk of the action consists of adventures on one or more exotic alien planets, characterized by distinctive physical and cultural backgrounds. Some planetary romances take place against the background of a future culture where travel between worlds by spaceship is commonplace; others, particularly the earliest examples of the genre, do not, and invoke flying carpets, astral projection, or other methods of getting between planets. In either case, it is the planetside adventures which are the focus of the story, not the mode of travel.

Infinity Science Fiction was an American science fiction magazine, edited by Larry T. Shaw, and published by Royal Publications. The first issue, which appeared in November 1955, included Arthur C. Clarke's "The Star", a story about a planet destroyed by a nova that turns out to have been the Star of Bethlehem; it won the Hugo Award for that year. Shaw obtained stories from some of the leading writers of the day, including Brian Aldiss, Isaac Asimov, and Robert Sheckley, but the material was of variable quality. In 1958 Irwin Stein, the owner of Royal Publications, decided to shut down Infinity; the last issue was dated November 1958.

There have been many attempts at defining science fiction. This is a list of definitions that have been offered by authors, editors, critics and fans over the years since science fiction became a genre. Definitions of related terms such as "science fantasy", "speculative fiction", and "fabulation" are included where they are intended as definitions of aspects of science fiction or because they illuminate related definitions—see e.g. Robert Scholes's definitions of "fabulation" and "structural fabulation" below. Some definitions of sub-types of science fiction are included, too; for example see David Ketterer's definition of "philosophically-oriented science fiction". In addition, some definitions are included that define, for example, a science fiction story, rather than science fiction itself, since these also illuminate an underlying definition of science fiction.
Black holes, objects whose gravity is so strong that nothing including light can escape them, have been depicted in fiction since before the term was coined by John Archibald Wheeler in the late 1960s. The earliest stories featuring what would later be called black holes, such as E. E. Smith's 1928 story The Skylark of Space and its "black sun", typically portrayed them as hazards to spacefarers. Later works such as the 1975 Space: 1999 episode "Black Sun" have occasionally done likewise, and a few have even depicted black holes being outright weaponized, one example being the 1982 novel The Space Eater by David Langford.
