Cult science fiction series Stargate SG-1 is on the verge of closing at the end of its current 10th season. Bosses at the Sci Fi Channel have chosen not to order further episodes of the show, the longest-running science-fiction series on TV.

The Stargate SG-1 series is based on the 1994 time-travel movie starring James Spader and Kurt Russell. Its 200th episode aired last week. The series' ratings have been in decline since long-running lead Richard Dean Anderson quit the show last year, but it still boasts a strong fan base, with several conventions staged globally every year.

Producers are refusing to let the show die completely - they're hoping to air a new season on a different cable network.
