Other Worlds, Universe Science Fiction, and Science Stories were three related US magazines edited by Raymond A. Palmer. Other Worlds was launched in November 1949 by Palmer's Clark Publications and lasted for four years in its first run, with well-received stories such as "Enchanted Village" by A. E. van Vogt and "Way in the Middle of the Air", one of Ray Bradbury's "Martian Chronicle" stories. Since Palmer was both publisher and editor, he was free to follow his own editorial policy, and presented a wide array of science fiction.
Palmer entered a partnership with a Chicago businessman in 1953 to create Bell Publications, and printed Universe Science Fiction from June 1953. Palmer used the new company to abandon Other Worlds and launch Science Stories, in order to escape from Clark Publications' financial difficulties. Hence Science Stories can be considered a continuation of Other Worlds. Science Stories was visually attractive but contained no memorable fiction. Universe, on the other hand, was drab in appearance, but included some well-received stories, such as Theodore Sturgeon's "The World Well Lost", which examined homosexuality, a controversial topic for the time.
Palmer's Chicago partner lost interest, so Palmer took over both Science Stories and Universe Science Fiction under a new company. In 1955 he ceased publication of both magazines and brought back Other Worlds, numbering the issues to make the new magazine appear a continuation of both the original Other Worlds and also of Universe. In this new incarnation the magazine was less successful, but did print Marion Zimmer Bradley's first novel, Falcons of Narabedla. In 1957 Palmer changed the focus of the magazine to unidentified flying objects (UFOs), retitling it Flying Saucers from Other Worlds, and after the September 1957 issue no more fiction appeared. Palmer eventually settled on Flying Saucers, Mysteries of the Space Age as the title, and in that form it survived until June 1976.
