Diane Duane is an American science fiction and fantasy author, long based in Ireland. Her works include the Young Wizards young adult fantasy series and the Rihannsu Star Trek novels.

"Where No One Has Gone Before" is the sixth episode of the American science-fiction television series Star Trek: The Next Generation, which originally aired October 26, 1987, in broadcast syndication in the United States. A high-definition, remastered version of the episode received a limited theatrical release for one day to celebrate the 25th anniversary of the series on July 23, 2012. The story was originally developed with the title "Where None Have Gone Before" and was based on Diane Duane's book, The Wounded Sky. Duane and Michael Reaves pitched the idea to David Gerrold and Gene Roddenberry, and then submitted a script. Their script was subsequently rewritten by Maurice Hurley, whose first effort was poorly received; however, he subsequently rewrote it and that version was filmed. The episode was the first of the series directed by Rob Bowman, who went on to direct 12 more episodes. It was the only Star Trek: The Next Generation assignment for writers Duane and Reaves.
