Stargate SG-1

From Academic Kids

Template:Infobox television Stargate SG-1 (popularly abbreviated as SG1 or SG-1) is a television series based upon the 1994 science fiction movie Stargate. MGM owns and licenses the show. The first episode was broadcast on July 27, 1997 on Showtime, which aired the series' first five seasons. Seasons six, seven, and eight were awarded to the SciFi Channel. During the eighth season (2004) the SciFi Channel began airing the first season of the spinoff series Stargate Atlantis. In November 2004, the SciFi channel announced that it would renew SG-1 for a ninth season, although none of the original cast members had yet signed contracts. Michael Shanks, Christopher Judge and Amanda Tapping all returned; however Richard Dean Anderson's character, Jack O'Neill, would not be a regular as (as rumoured) O'Neill will be promoted again to replace General George Hammond's position in The Pentagon. This tied SG-1 with The X-Files as the longest-running sci-fi drama series on American television. Unlike sci-fi franchises such as Star Trek or Babylon 5, SG-1 is set in the present day.



See Stargate for a general summary of this universe.

The series follows the adventures of four explorers designated as SG-1, who use an alien artifact called a 'Stargate' to travel the vast distances between planets, operating under the aegis of the United States government. The very existence of the Stargate Command and all of its activities are covert and SCI-classified ("Sensitive Compartmented Information").

The four original members of SG-1 were Colonel Jonathan "Jack" O'Neill, Captain Samantha "Sam" Carter, Dr. Daniel Jackson and Teal'c, an alien Jaffa. In season three Carter was promoted to major. For season six, Jackson was replaced by Jonas Quinn, an alien human, but Jackson returned to the show for season seven.

Originally led by Major General George Hammond, Stargate Command is based out of Cheyenne Mountain Air Force Station, Colorado. The U.S. Air Force is in direct charge of the Stargate program, although from early on there was at least one SG team comprised of U.S. Marines. In later seasons there was considerable participation in the Stargate program by civilians and non-Americans, including at least one Russian SG team.

At the end of season seven, Hammond was promoted to Lieutenant General and reassigned to the "Office of Homeworld Security" in the Pentagon. Dr. Elizabeth Weir assumed temporary command of the SGC, after which she was reassigned to the Antarctic base and, subsequently, as leader of the "Atlantis" mission (See Stargate Atlantis). O'Neill was promoted to Brigadier General and he in turn promoted Carter to Lieutenant Colonel and team leader of SG-1.

(For season nine, General Hank Landry replaces O'Neill as commander of the SGC, Dr. Carolyn Lam replaces Brightman and Fraiser as Chief Medical Officer, and Lt. Col. Cameron Mitchell will be the new CO of SG-1 for at least the first 5-6 episodes.)

One of the most endearing qualities of Stargate SG-1 is that it takes place in the present day. Humans, as depicted in the series, are technologically behind some the alien races the Stargate teams have met, but are rapidly gaining the ability to fight, defend, and benefit from the advances they have been exposed to in both significant and material ways.

The primary goal of the SG teams is to travel to other worlds through the Stargate and procure alien technology to help defend Earth against the Goa'uld, who became aware of the planet's now relatively advanced civilization after the recovery of Earth's Stargate and the subsequent destruction of Ra, the supreme Goa'uld System Lord (the events depicted in the 1994 movie). The Stargate teams were frustrated in initial efforts to acquire advanced technology to fight the Goa'uld from more advanced species and offshoots of humanity. Three attempts were made to reverse-engineer alien technology and build its own starships, leading to the production of the F-302 and BC-303 models.

Stargate SG-1 is notable for featuring many characters from other prominent science fiction series as guest stars on its show. These included Jolene Blalock (Star Trek: Enterprise), Robert Picardo (Star Trek: Voyager), and Claudia Black (Farscape). This trend extends to Atlantis, which featured Colm Meaney (Star Trek: The Next Generation), as well as Robert Patrick and Mitch Pileggi (both of The X-Files). The recent incorporation of Ben Browder (Farscape) as a regular character further cements this trend.

The show remains popular despite entering its ninth season on the air. TV Guide recently proposed that its popularity may be exceeding that of the Star Trek franchise. Stargate SG-1 continues to break records in terms of Nielsen Ratings for the Sci-Fi channel, while the eighth season two-part episode "Reckoning" was widely regarded by fans as one of the five best in the show's history. Although Richard Dean Anderson will be departing the show as a regular in season nine, he will appear in the first and third episodes of that season and has left the door open for future appearances.

The USAF cooperates closely with the makers of the program. Two successive Chiefs of Staff of the USAF, Generals Michael E. Ryan and John P. Jumper, have appeared in the show, playing themselves. Ryan appeared in the episode "Prodigy" (4x19) because of his fascination with science fiction, especially space exploration. Jumper made a cameo appearance in "Lost City" (7x22), the episode that was originally slated to be the show's last. The Air Force Association recognized Richard Dean Anderson at its 57th annual dinner on September 14, 2004 for his work as actor and executive producer of the show and "for the show's continuous positive depiction of the Air Force."

Alien Races

There are several alien races in Stargate SG-1.


  • Goa'uld: The dominant parasitic lifeforms of this galaxy. Goa'ulds are snake-like aliens who burrow into the upper spinal cords of humans or humanoids and take control of the "host's" body and mind. For centuries, they ruled Earth by claiming to be gods, and so they resemble the gods of Earth mythology. Most have trace amounts of naquadah in their blood. The show consistently calls the Goa'uld a symbiote, even though most biologists would use the term symbiont.
  • Jaffa: Humanoid species with marsupial-like pouches, which were genetically engineered from humans. Their pouches serve to incubate a Goa'uld larva for approximately 100 Earth years. Though the symbiote gives strong healing capabilities and strength to the Jaffa, it robs them of their own immune system, requiring them to have a symbiote or take the drug tretonin at all times. The Jaffa constituted the majority of the military strength of the Goa'uld. However, due to the Jaffa rebellion, some Goa'uld, most notably Anubis, now use Kull Warriors as their primary troops.
  • The Tok'ra: Opposing the Goa'uld are the Tok'ra (literally, "Against Ra"). Though the same species as the Goa'uld, the Tok'ra have fought the Goa'uld for millennia and have come to ally with the Tauri (humans from Earth) against the System Lords. Unlike the Goa'uld, who take over the host body completely, the Tok'ra respect their hosts and freely share the body with the human mind that still inhabits it.
  • Unas: The first host for the Goa'uld; they coexisted with them on their original planet. The Unas possess incredible physical strength and when taken as a host have the ability to regenerate from almost any wound thanks to the healing powers of the Goa'uld. Few Unas are still used as hosts, having been abandoned in favor of humans' greater dexterity and hands able to manipulate fine machinery.
  • Kull Warriors: Creatures genetically engineered by Anubis for use in his personal army. Given life and enhanced, they are essentially blank slates bred for obedience and war. Their suits are impervious to all main weapons and explosives, including C-4 and other highly explosive compounds. Small trinium darts, however, can penetrate the suit. The Kull Disruptor was eventually devised by the Tauri and the Tok'ra using an Ancient healing device discovered by the Goa'uld Telchak and is capable of bringing a Kull Warrior down in one or two shots. After the defeat of Anubis it is possible that the System Lord Ba'al took control of Anubis's army, which may include some Kull Warriors

The "Four Great Races"

An alliance who, at one time, would come to a particular planet (unknown to the Goa'uld) and interact as "a sharing of clans to share a common interest".

  • The Asgard: Physically identical to (Roswell) Greys, the Asgard are a benevolent, highly advanced and evolved race who have visited Earth on many occasions from the galaxy Ida, and who also gave rise to the Norse legends. The Asgard are enemies of the Goa'uld, and thus allies to the Tauri. The Asgard are no longer able to reproduce in the traditional sense, and must use cloning technology in order to survive by cloning their bodies and then transplanting their minds into the new one. They are constantly at war with the Replicators.
  • The Ancients: An unbelievably advanced race that was originally humanoid, that inhabited Earth millions of years ago. They are credited with building the system of Stargates and possessing technology that surpasses anything known throughout the Stargate science-fiction universe. The Ancients expanded their gate system to numerous galaxies, the most notable being the Pegasus Galaxy. After the vast majority were wiped out by a plague, they fled to Pegasus via their "flying city" several million years ago. However, after flourishing in this new galaxy they encountered a race that they could not effectively defend themselves from. Thus a 100 year bloody war with a race of beings known as The Wraith, whose psychic and physical abilities rivalled those of the Ancients. The war cost the Ancients dear, and they eventually quit Pegasus, leaving behind the city of Atlantis, hidden beneath several hundred feet of ocean. The few Ancients who survived the war returned to Earth to live out the rest of their days. Physically indistinguishable from humans, although apparently somewhat more intelligent, and possessed of abilities from a gene known as Ancient Technology Activation (or ATA). No Ancients now exist on a mortal plane of existence, having ascended to a higher state of being, a state which some of the show's characters (most notably Daniel Jackson and the population of Abydos) have since achieved and then returned.
  • The Nox: A peaceful and fairy-like people, who are capable of reviving the dead and rendering even large objects invisible. They are entirely against violence of any kind.
  • The Furlings: Little is known about the Furlings, save that they are a member of the alliance of the Four Great Races. However, occasional artifacts attributed to the Furlings have been identified. In the episode "Paradise Lost", an old utopian colony established by the Furlings and wiped out by a Goa'uld bearing a mind-altering drug.


  • The Replicators: a mechanical life form composed of building blocks using nanotechnology. They strive to increase their numbers by assimilating advanced technologies. They are opposed primarily by the Asgard. In the episode "Unnatural Selection", the Replicators had developed human-form Replicators that appear just like humans and are able to change their form. Standard Replicators are resistant to energy weapons, and can only be destroyed by projectile weapons. Human-form Replicators, on the other hand, are resistant to projectile weapons as well. In one part of the two-part episode "New Order (Part 2)", an Ancient weapon called the Replicator Disruptor was developed by Jack O'Neill while he still had the knowledge of the Ancients. It works by blocking the cohesion between the blocks that made up the Replicators.
  • The Gadmeer: Existed for thousands of years, before being wiped out. They created a ship for the purpose of terraforming a new planet to live on.
  • The Re'tu (or Reetu): Enemies of the Goa'uld. They appear to be large spider-like creatures. They exist 180 degrees out of phase from the normal visual spectrum, making them invisible except under a TER.
  • The Re'ol: Almost wiped out by the Goa'uld, the Re'ol have a unique natural defense: one of their bodily secretions is used to create false memories when it comes in contact with a living creature. A Re'ol managed to infiltrate SG-1 in the episode "The Fifth Man" as Lt. Tyler.
  • The Oannes: Nem and Omaroca are the only members of this species known. In the episode "Fire and Water", Nem kidnaps Daniel Jackson to find out what happened to his mate Omaroca.
  • The Serrakin: Seen in "Forsaken" and "Space Race", the Serrakin helped free the Hebridans from a Goa'uld, who is possibly Morrigan, a long time ago. They brought a lot of highly advanced technology with them, making the Hebridans one of the most technologically advanced Human civilizations. The Serrakin and the Hebridans live mostly peacefully together and are known to marry people of the other species.
  • The Spirits: Seen in the episode "Spirits", the race defeated the Goa'uld a millennia ago, and coexisted with the Salish as the Salish gods.

There are several lesser alien species in the show.

Human civilizations on other planets

The Goa'uld used Stargates to transport large numbers of humans to other planets for use as slaves. Some of these groups were later abandoned (usually due to a decline of easily mined naquadah deposits) and developed on their own to a level of technology far greater than that of contemporary Earth. The premise is that had this world not experienced the Dark Ages, it would also have developed to such advanced levels.

Advanced human civilizations

  • Aschen: A seemingly benevolent race, SGC made contact with them through the Stargate (which the Aschen had not yet fully learned to use, as they had no DHD to go with their 'Gate). They agreed to help against the Goa'uld, although it was discovered they had another agenda. Deciding against outright conquest, they slowly sterilized the population of Earth so that, within a century, they could simply walk in and take control of the planet. In an alternate timeline SG-1 used the Gate to send a message back in time to prevent their past selves from receiving the same fate.
  • The Hebridans: Descended from Celtic islanders, this race is perhaps one or two hundred years ahead of Earth. First seen in "Forsaken", it is thought that their ancestors may have been transplanted from earth by The Goa'uld System Lord Morrigan. It is also most likely that their closely allied race the Serrakin defended and freed the Hebridans from Morrigan.
  • The Orbanians: A Race that uses Nanotechnology to greatly enhance and accelerate learning. First seen in "Learning Curve".
  • Tagreans: The Tagreans are a human race shortly ahead of Earth in technological development. They were apparantly transplanted by the Goa'uld System lord Heru'ur.
  • The Tollan: Highly advanced race of humans on the planet Tollana. After having shared their advanced technology with a less-advanced race, that race used the technology to destroy themselves. Henceforth, the Tollan have adopted a strict policy forbidding them from sharing technology with less-advanced races. It is thought that their ancestors were transplanted from Earth by the Goa'uld System Lord Tel'chac.

Less advanced human civilizations

  • Bedrosians:
  • Cimmerians: A race descended from the Norse Vikings.
  • Edorans:
  • Latonans:
  • Langarans: A race with technology on par of mid 20th Century Earth, their planet consists of three countries: the Kelownans (Jonas Quinn's people.), the Terranians, and the Andari Federation
  • Nasyans: A peaceful people that aren't very technologically advanced. They were seen in the episode "In the Line of Duty". They were eager to make friends with the Tau'ri and allowed them to build a camp on their world for scientific research. The Goa'uld found their world and forced the Nasyans to evacuate to Earth and move to another planet.
  • Madronans: The Madronans are a primitive race that was first seen in "Touchstone". Their planet once had a hostile climate until it was terraformed by a more advanced race. The Madronan priestess uses a device called the Touchstone to control the weather.
  • Pangarans: The people who first developed Tretonin.
  • Salish: A race descended from ancient Native Americans.
  • Volians:
  • Vyans:


There exist a number of more technologically advanced races and societies on the show, who have produced a variety of highly-advanced weapons, tools, and spacecraft. Some of these are listed below.

Earth technology

  • X-301. First attempt to reverse-engineer an alien spacecraft, the Goa'uld Death Glider. The effort failed when the Goa'uld activated a built-in recall device to retrieve the stolen Glider.
  • X-302. Second experimental fighter program. Designed and built with Earth-based technology. Earth's first attempt to create hyperspace-capable ships. Prototype destroyed in mission to save Earth from destruction by Anubis.
  • F-302. Final design of the X-302 experimental program. The F-302 is the standard interceptor fighter used by U.S. space forces. Space-capable, hyperspace-capable for short distances. Carries standard U.S. Air Force weapons.
  • X-303. Experimental capital ship produced as an Earth/alien hybrid. Developed under code name Prometheus, eventually became the name of the first ship of the class. Designed to use missiles as primary weapons; Asgard shields and weapons were later added.
  • BC-303. Production designation of the Prometheus-class battle cruiser. The Daedalus is the second ship of the class and was designed and built to carry alien shields and weapons. Hyperspace-capable; can carry eight F-302 Interceptors or Death Gliders.
  • M4 Carbine. Standard assault rifle for the SGC.
  • MP5. Standard submachine gun used by the SGC.
  • P90. The weapon of choice for SG-1; different teams have different weapons.
  • GDO (short for "Garage Door Opener). Transmits a coded radio signal to transmit an Iris Deactivation Code (IDC) to Stargate Command through the event horizon of the Stargate.
  • Iris. Blocks incoming traffic; developed to prevent other alien races from dialing Earth and invading. Can be deactivated by a GDO.
  • MALP. Mobile Analytic Laboratory Probe: wheeled robotic probe used to explore alien planets without endangering SGC personnel.
  • FRED. The Field Remote Expeditionary Device is a six-wheeled cargo vehicle used to carry supplies through the Stargate.
  • UAV, or Unmanned Aerial Vehicle. The SGC has several variants of the RQ-1 Predator: a long-range reconnaisance vehicle, a rocket launcher, and a target designator that "paints" targets with a red laser beam to guide Maverick missile attacks from the SGC through the Stargate.
  • AGM-65 Maverick. The SGC has modified the AGM-65 Maverick missile so that it can be fired through the stargate against targets designated by infrared targeting. Both UAVs and ground troops may paint the target for the Maverick missiles to strike.
  • Naquadah Generator.A naquadah-powered generator that provides almost endless amounts of clean energy.
  • Rail Gun. Installed on the Prometheus but also used to defend Atlantis from Wraith fighter ships.
  • Kull Disruptor. Developed with the Tok'ra to fight Kull Warriors. Originally installed on a Transphase Eradication Rod, it has since been shrunk to fit as an attachment to a P90.

Goa'uld technology

  • Zat'nik'tel. A commonly used weapon, the zat'nik'tel is typically used to render a victim unconscious. One shot causes pain and unconsciousness, two shots kills, and three shots disintegrates the victim. Originally seen in "Within the Serpent's Grasp". They are commonly referred to as "zats" or "zat gun", and are often used to disable electronics or elminate enemies without killing them.
  • Staff weapon. Originally seen in the movie Stargate, it is an energy blast weapon, and is the standard firearm for the Jaffa. Also used for hand-to-hand combat.
  • Hand Device. Ra's glove weapon from the movie Stargate. This is the personal weapon of the Goa'uld themselves. It can only be used by those who have Naquada in their blood (mostly current or previous Goa'uld hosts). It can be used to telekinetically knock away foes, subdue them by inducing a sort of trance or torture/kill them by directing it over their forehead at close range.
  • Sarcophagus. Used to revive the dead and heal the wounded. It also serves to extend the life of the Goa'uld. In un-blended humans, it can affect judgement and create addiction after repeated use, like a drug, as seen in the episode "Need". The Tok'ra don't use it because they believe it is what makes the Goa'uld evil.
  • Death Glider. Fast attack fighter, generally piloted by Jaffa in service to a Goa'uld.
  • Tel'tak. Unarmed cargo ship, typically carries four escape pods and a set of Ring Transporters. Some are equipped with a cloaking device. The ship is divided into two major sections -- the flight deck, onto which the main entrance opens, and the cargo area. They are separated by a bulkhead, which is removable to allow for more space during flight.
  • Al'kesh. Mid-range bomber, equipped with energy weapons, a cargo hold, and a Ring Transporter.
  • Ha'tak Mothership. Goa'uld Mothership, the most powerful standard vessel in the Goa'uld fleet. It is shaped like the great Pyramids of Egypt.
  • Troop Transport. Large, heavily armored Goa'uld transport vessel. The troop transport can carry a large army of Jaffa ground forces into battle.
  • Healing Device. Worn on the hand in a manner similar to a hand device, it allows a Goa'uld or former host to heal injuries.
  • Shield. All Goa'uld capital ships and some Goa'uld leaders utilize energy shielding for protection. In the case of personal shielding, the shield's power is directly proportional to the kinetic energy of the projectile it is blocking. This makes the shield powerless against slow moving projectiles, like arrows. However, most Goa'uld seem to have adapted to that fault and fixed it.
  • Pain Stick. A weapon used by the Goa'uld to torture their prisoners, sometimes for information, sometimes for pure entertainment. It causes extreme pain and light to shine out of the victims mouth, ears and eyes.

Tollan Technology

  • Ion Cannon. Used to protect the Tollan planet of Tollana from Goa'uld attack. A single shot can destroy a Goa'uld Ha'tak Mothership. However, Anubis was able to develop a counter-measure against it.
  • Weapon Disabler. Does just as the name suggests: disabling weapons of visitors to the Tollan homeworld. Typically placed in the entranceways of important government buildings. To emphasize this point, the only use seen in the series is while SG-1 is entering the Triad room, the counterpart to Earth's courtroom.
  • The Tollan also possess portable devices that allow person-sized objects to pass through solid matter.
  • Reverse-Engineered Stargate. With the destruction of the original Tollan homeworld, the Tollan's Stargate was also destroyed. When they moved to their new homeworld, Tollana, a new Stargate was built with the assistance of the Nox. The new gate is much smaller and slimmer than the Ancients' Stargates. It also seems to lack a DHD, or even an inner track for manual dialing, suggesting remote dialing.
  • Personal Faster-Than-Light communication devices. When a group of Tollans were being detained on Earth, they were able to contact their world without using the Stargate. It does not work by warping or bending space, as one condescending Tollan explained to Daniel Jackson.

Ancient Technology

  • Ring Transporter. A teleportation system in use today by the Goa'uld and Tok'ra, and used by humans aboard the Prometheus.
  • The Stargates were created and distributed by the Ancients, along with DHDs (short for "Dial Home Device") to control them.
  • Time Travel Machine. Ancient attempt to make a time travel device to save themselves. It was perfected by Janus, one of the Ancients seen on the TV show Stargate Atlantis. SG-1 found that time machine and used it to go back to the days where Ra was alive and the Goa'uld ruled Earth in the two-part season finale "Moebius". There was also a much larger time machine, which dialed several planets to form a subspace bubble; however, it possessed a flaw that instead of travelling back in time, it created a short-term time loop, which forced the planets that the device used to relive the same day over and over again.
  • DNA Resequencer. Device used by Nirrti in the episode "Metamorphosis". Nirrti used it to corrupt the DNA of people living in a nearby village.
  • Repository of the Ancients. Device that stores the collective knowledge of the Ancients. It is seen in the episodes "The Fifth Race", and "Lost City, Part 1". The transfer of knowledge from this device can cause serious problems for beings whose physiology is not prepared to take the mental strain.
  • Zero Point Module. A device used by the Ancients to power their technology using zero-point energy. It is more powerful and efficient than any energy source on Earth, and can last for thousands of years. Jack O'Neill managed to obtain one at an abandonded Ancient outpost and used it to power Ancient weaponry to repel Anubis's attack on Earth. The same ZPM was also what allowed Stargate Command to open a wormhole to the Pegasus Galaxy, providing the backdrop for Stargate Atlantis.
  • Weapon Drone. A device that is shaped like a jellyfish, which is capable of targeting and destroying a small vessel. Many of these drones can destroy a larger vessel, as demonstrated in one part of the two-part episode "Lost City, Part 2" when they destroyed Anubis's mothership, which was preparing to attack Earth. They can also penetrate energy shields. Its power was shown in the episide "It's Good to be King" where SG-1 destroyed a whole mothership with a single drone. The drones also have a very advanced guidance system, allowing them to automatically home in on and destroy smaller and faster targets.
  • Dakara Superweapon. Can selectively reduce any compound within range to its basic atoms. It can destroy all life in the galaxy if sent through the Stargate network. This weapon was used to eliminate the Replicators in the two-part episode "Reckoning" and was subsequently destroyed by the rebel Jaffa in the episode "Threads" for fear it would fall into the wrong hands (i.e. Anubis).
  • Puddle Jumpers. Spacecraft used by the Ancients that are capable of travelling through the Stargate.

Tok'ra Technology

  • Symbiote Poison. Invented by the Tok'ra. Stargate Command meant to use it to kill all the System Lords in the episodes "Summit" and "Last Stand". However, because the poison kills all symbiotes indescriminately (Goa'uld, Tok'ra and the Prim'tahs within the Jaffa), the SGC has decided not to use it so as not to kill innocent Jaffa.
  • Crystal Tunnels. The Tok'ra's key method of hiding their bases from the Goa'uld. These tunnels grow the way the Tok'ra want them and can be quickly collapsed when a base is discovered by the Goa'uld.
  • Tretonin. Originly created by the Pangarans but further refined by the Tok'ra so it can be made without having to harvest symbiotes. The Pangarans used it to boost their immune systems but shortly discovered it wasn't the best solution. However, the Tretonin, as refined by the Tok'ra, can be successfully used on the Jaffa so they don't need to have larval Goa'uld within them.
  • Mothership Locater. Used to detect whereabouts of Goa'uld motherships that are located within the galaxy.
  • TER. The TER (Transphase Eradication Rod) serves two purposes; first, it has a scanning light which causes cloaked objects or objects cloaked by being 180 degrees out of phase with our own reality to appear. Secondly, it is an energy weapon with the ability to kill a Re'tu.
  • Zatarc Detector. An advanced lie detector used by the Tok'ra to detect enemy spies amoungst their ranks but has also been used for other means.

Asgard Technology

  • Beaming Device. Used to instantly transport a person or objects from one place to another. This technology is used mostly on Asgard ships however Anubis was able to steal the technology from the Azgard by probing Thors mind.
  • Time Dilation Device. This was used by the Asgard to trap the replicators in a time bubble where time slowed down significantly enough to let the Asgard have more time to figure out how they were going to combat the Replicator threat however the replicators were able to modify the device so it speed up time.
  • Thor's Hammer. A device used to detect Goa'uld including Jaffa and transport them to a cave where the only exit was through a piece of technology that would kill the symbiote but preserve the host.


A number of different planets are seen throughout the series.

  • Earth: The homeworld of the Tauri (humans from Earth) and the Ancients.
  • Chulak: a Jaffa homeworld, formerly controlled by Apophis. Teal'c's homeworld.
  • Abydos: the planet visited in the original Stargate movie, as well as several times during the series. Homeworld of Sha're & Skaara
  • Tollana: the homeworld of the Tollan until their destruction.
  • Hanka: P8X-987, the homeworld of Dr. Fraiser's adopted daughter, the population of which was wiped out by a plague set in motion by Nirrti.
  • Altair: P3X-989, the homeworld of Harlan, the first robotic lifeform seen in the series.
  • Langara: homeworld of Jonas Quinn.
  • Othala: The Asgard world of origin. Othala's solar system was trapped within a pocket of accelerated time created by a "Time Dilation Device" in a failed attempt to eradicate the replicators.
  • The Alpha Site: a designation for an uninhabited world set up in case Earth (or any other Human-controlled world) has to be evacuated.

There are also many lesser planets.
