Stargate SG-1 is a science fiction TV series that blends action, adventure, and exploration with a touch of humor and drama. It revolves around a team of Earth-based explorers, SG-1, who use an ancient alien device called the Stargate to travel instantaneously to other planets.
The Stargate is a massive ring-shaped portal that creates wormholes, connecting distant parts of the galaxy. It was discovered on Earth and serves as the foundation for Earth’s efforts to explore space, establish alliances, and defend against alien threats. Stargate SG-1 is a sequel to the 1994 film Stargate.
During its run, the series featured performances by Richard Dean Anderson, Michael Shanks, Amanda Tapping, Christopher Judge, Don S. Davis, Corin Nemec, Ben Browder, Beau Bridges and Claudia Black.

9. In Season 6, Carter (Amanda Tapping) stated that the Stargate, constructed from Naquadah, weighed 64,000 pounds (approximately 29 metric tons).
However, the primary on-set Stargate prop was crafted from steel and fiberglass. Measuring 22 feet (6.7 meters) in diameter, it was fully automated, capable of rotating and emitting light.
This functionality was made possible by a custom-designed 22-foot (6.7-meter) circular gear, which turned the inner ring with precision using a pinion drive wheel powered by an 8-horsepower electric motor.
10. Astronomers David Tholen and Roy Tucker, fans of the show, named the large asteroid 99942 Apophis in 2005 (after one of the villians on the show).
Initially, there was concern that the asteroid could collide with Earth in 2029, potentially causing catastrophic damage. However, subsequent and more precise analyses have confirmed that Apophis will safely pass by without impact.
11. Stargate SG-1 featured four distinct opening credit sequences. The first, used for the premiere and Showtime airings, was a non-clip version inspired by the Stargate (movie, featuring a pan around Ra’s statue. The second sequence, used for syndicated airings, included clips from the series.
The third version, used on the Syfy Channel, was similar to the first but focused on an activating Stargate and concluded with SG-1, seen from behind, entering the Stargate. The fourth version, appearing in the first half of Season 9, depicted a Stargate floating in space, SG-1 walking toward it at the SGC, and the camera traveling through the active Stargate. The third version returned for the latter half of Season 9.
12. The prop used to represent the device controlling the Tok’ra memory recall device, resembling a “wand,” is actually an unmodified electric nose hair trimmer.

15. The series was initially intended to conclude after seven seasons with a feature film serving as its finale.

16. Stargate SG-1 was known for its occasional self-referential humor. Notably, the 100th episode (Wormhole X-Treme! (2001)) and the 200th episode (200 (2006)) featured storylines filled with self-aware moments and numerous in-jokes.

Prominent Goa’uld adversaries included Apophis, Anubis, Ba’al, and Ra), The Replicators (A relentless, self-replicating, machine-like species that consumed technology and resources, posing a significant threat to the galaxy), The Ori (Powerful ascended beings who demanded worship from lower planes of existence, imposing their will through their followers and armies known as the Ori Priors) and The Lucian Alliance (A criminal organization that emerged in the later seasons, taking advantage of the power vacuum left by the defeated Goa’uld).
19. The sound of the Goa’uld Ha’tak mothership’s main weapons firing bears a strong resemblance to the iconic roar of Soviet WWII Katyusha rocket launchers.
20. Brad Wright and Jonathan Glassner (the creators of Stargate SG-1), who had previously collaborated on the MGM series The Outer Limits since 1995, both independently approached MGM after hearing about plans to create a television spin-off of Stargate. Unaware of each other’s actions, they each proposed their own concepts for the series.
MGM president John Symes approved the project on the condition that Wright and Glassner work together as executive producers. The series was named Stargate SG-1 after Wright casually agreed to Symes’s suggestion of the name. Posters with the title were released within the week, unbeknownst to Wright and Glassner.
21. Symes reached out to Michael Greenburg and Richard Dean Anderson, who had starred in MacGyver. Anderson agreed to join, provided his character, Jack O’Neill, was given more comedic freedom than Kurt Russell’s portrayal in the film, and that the show would be an ensemble piece, rather than relying solely on him.
