The Promethean Galaxy, one of the most remote regions of the universe, lies near to the Source Wall, the "Final Barrier" beyond which lies the answers to the nature of the Source. Beings known as the Promethean Giants attempted to breach the Wall, and now drift through space in suspended animation for their hubris. Metron often came to the Promethean Galaxy to contemplate the Source.

"You maniac. The whole ship's gonna blow!" "Not the whole ship." ―Rocket Raccoon and Yondu Udonta[src] The Quadrant is a detachable part of the Eclector. It was used by Yondu Udonta, Rocket Raccoon, Groot and Kraglin Obfonteri to escape the Eclector and rescue the Guardians of the Galaxy on Ego's planet.

Escape from the Eclector

"Get the third Quadrant ready for release." ―Yondu Udonta to Kraglin Obfonteri[src] Feeling sorry for the loss of his fellow Ravagers following Taserface's mutiny against Yondu Udonta, Kraglin Obfonteri decided to release his former captain, apologizing for the turn of events. In response, Yondu ordered Kraglin to be ready to release the Quadrant and to await him as well as Rocket Raccoon and Groot.

Yondu, Rocket and Groot escaped from their cell and killed most of the traitorous Ravagers, causing an explosion which set the Eclector on fire. Before the massive spaceship was blown up, they joined Kraglin in the Quadrant and released it from the Eclector as it exploded. Rocket then decided to rescue his friends and set course for Ego's Planet through 700 Jump Points, causing their bodies to disfigure temporarily due to the amount of jumping the ship performed.[1]

Battle on Ego's Planet

When they arrived on Ego's Planet, Kraglin Obfonteri stayed in the Quadrant while Yondu Udonta, Rocket Raccoon and Groot went to rescue the Guardians of the Galaxy in the Laser Drill. However, while Kraglin was waiting for his teammates to return and leave Ego's planet, a fleet of Sovereign Omnicrafts approached the planet. Kraglin flew down to the planet to retrieve the Guardians and as he went to open the door, Drax the Destroyer took an unconscious Mantis to the ship. However, they were attacked by Ego who wrapped massive tentacles around the ship nearly turned it upside down. Fortunately, Kraglin activated the thrusters to balance the Quadrant and avoid crushing Drax and Mantis.

As the planet was about to explode, Gamora and Nebula joined the others on the ship, later followed by Rocket and Groot. As Star-Lord and Yondu were still on the planet, Gamora intended to find them, but Rocket rendered unconscious and ordered Kraglin to take off before the blast. Yondu ultimately chose to sacrifice himself to save Quill, and both Quill and Yondu's body were brought to the Quadrant.[1]

Following the battle against Ego, the Guardians of the Galaxy held a funeral for the fallen Yondu Udonta on the Quadrant. After Peter Quill's eulogy, Yondu's body was cremated in the Quadrant's reactor, spreading colored ashes into outer space. The Quadrant was soon surrounded by spaceships from all other Ravagers clan called by Rocket Raccoon so that they could pay their respects to their late comrade.

Meanwhile, Nebula decided to chase and try to kill her adoptive father Thanos. After bidding farewell with her sister Gamora, Nebula left the Quadrant on a spacecraft.[1]

File:Galactic Quadrant.PNG

In the television series Star Trek and its spin-offs, Galactic quadrant refers to an area of the Milky Way Galaxy. In the original Star Trek, it referred to an area interchangeable with a sector. However, in the various spin-off series and movies beginning with Star Trek: The Next Generation, it refers to a system of four Galactic Quadrants, designated by the Greek letters Alpha, Beta, Gamma, and Delta, has been used.

Contents[show]

Original usage

The original usage of 'quadrant' appears in episodes such as "The Deadly Years" and "The Squire of Gothos", where numbered quadrants (448 and 904) are given.[1] In other episodes it appears to refer to an entire quarter of the galaxy.[2] The season 3 Star Trek: The Next Generation Writers' Technical Manual asserts that there are 4 quadrants in each sector (which seem to vary in size).[3]

Four quadrants

The 1988 Star Trek: The Next Generation episode "The Price" introduced the concept of four quadrants of the galaxy, named the Alpha, Beta, Gamma and Delta quadrants.

Star Trek VI: The Undiscovered Country implies that the Alpha/Beta border runs through, or is relatively close to, Federation space. The Star Trek Encyclopedia attributes this decision to rationalize a line in Star Trek II: The Wrath of Khan, in which James T. Kirk claimed that the Enterprise was the only ship in a Quadrant.[1][2] Maps produced by the art staff for the series (both on-screen and published) show that the Alpha/Beta border runs through the Sol system.[4]

Alpha and Beta Quadrants

Assuming the galactic meridian runs from the center of the galaxy through Earth's solar system, then the Alpha Quadrant is between 180 degrees and 270 degrees, and the Beta Quadrant is between 90 degrees and 180 degrees.

The Alpha Quadrant and the nearby areas of the Beta Quadrant are the primary setting of Star Trek: The Original Series, Star Trek: The Next Generation, Star Trek: Deep Space Nine, and Star Trek: Enterprise. According to the Encyclopedia, the Federation is largely on the Alpha Quadrant side, but with parts in the Beta Quadrant; whereas the Klingon and Romulan Empires are mainly in the Beta Quadrant but extend in part into the Alpha Quadrant.[2] The Star Trek Star Charts have the Romulans and Klingons entirely within the Beta Quadrant, as well as the Gorn Hegemony, the Son'a Solidarity and the Metron Consortium. Star Trek Star Charts further located the First Federation, Breen, Ferengi, Tzenkethi, Cardassians, Bajorans, Talarians and Tholians in the Alpha Quadrant.

Of core worlds, Star Trek Star Charts claims that Vulcan (40 Eridani), Andoria (Procyon), Risa and the Rigel (Beta Rigel) systems are in the Beta Quadrant, with Tellar (61 Cygni), Trill and Betazed in the Alpha Quadrant.[4]

Star Trek Star Charts has the Romulans corewards and counterclockwise from the Federation core, with the Klingons rimwards of the Romulans. Federation territory is shown to expand around the backs of the Klingon and Romulan Empires, further into the Beta Quadrant. Other powers such as the Cardassians, Tholians and Ferengi are on the clockwise side of the Federation. The 1975 Star Fleet Technical Manual by Franz Joseph also has a galactic meridian running through Sol, but depicted the Romulans as being counterclockwise, and the Klingons as being clockwise.

Although the Romulans and Klingons are shown by maps as part of the Beta Quadrant, Star Trek: Deep Space Nine did not use this terminology, referring to them as Alpha Quadrant powers. Ronald D. Moore noted that the "Alpha quadrant is firmly planted in the audience's mind as where the Federation, the Klingons, and the Romulans all live so I think we'll stick with that nomenclature".[5]

About 600,000 years ago, the Alpha Quadrant was dominated by the Tkon Empire, which is long since vanished by the time of the Star Trek series.

Gamma Quadrant

The Gamma Quadrant is situated between 270 degrees and 360 degrees. It is the home of the Changelings, or Founders. The majority of it is ruled by the Dominion.

Bajoran wormhole

File:Bajoran wormhole.jpg

In the fictional Star Trek universe, the Bajoran wormhole is a spatial anomaly located near the planet Bajor. The Bajoran religion refers to the wormhole as the "Celestial Temple". It appears as an aperture of swirling golden light surrounded by blue clouds, which appears when a vessel approaches and disappears when the vessel enters it; it also appears when discharging a vessel. The wormhole can only be traversed by ships traveling at impulse (sub-light speed) velocities.

The wormhole is discovered in the first episode of Star Trek: Deep Space Nine. It is found to lead from the Bajor-B'Hava'el system in the Alpha Quadrant to the Idran system in the Gamma Quadrant, seventy thousand light-years away and on the other side of the galaxy. Due to the strategic importance of such a phenomenon, the Deep Space Nine space station is moved out of Bajor's orbit and repositioned near the wormhole.

Starfleet Commander Benjamin Sisko and Lieutenant Jadzia Dax are the first to make contact with the wormhole and its creators, incorporeal beings known as the Prophets in Bajoran religion; they are simply referred to as "Wormhole Aliens" by the Federation. It is they who provided the Orb-like energy artifacts (or "Tears of the Prophets") to the Bajorans and these artifacts are the basis of Bajoran religion.

The wormhole becomes a point of conflict throughout the series, since it permits travel between the Alpha Quadrant and the Gamma Quadrant controlled by The Dominion, a malevolent organization led by the Changelings, a race of shapeshifters. Neither the Dominion nor the major powers of the Alpha Quadrant wish the other to gain a foothold in their relative quadrants, which explains the strategic importance of the wormhole running between them. The wormhole closes at one point, as a result of one of the Tears of the Prophets being temporarily rendered inert by the Pah Wraiths. It is later restored by the discovery of an additional orb by Benjamin Sisko.

Delta Quadrant

The Delta Quadrant is situated between 0 degrees and 90 degrees.

Most of the information about the Delta Quadrant and its inhabitants comes from the show Star Trek: Voyager. Apart from the voyages of the USS Voyager, the USS Equinox, the USS Raven, briefly the USS Enterprise NCC-1701-D, and the Federation citizens assimilated or de-assimilated from the Borg, the United Federation of Planets has not yet fully explored this quadrant.

The Delta Quadrant is home to the Borg Collective, the Kazon, the Vidiians, the Talaxians, the Ocampa, the Hirogen, the Malon, as well as many others. Species 8472, beings from "fluidic space", are first encountered in this quadrant, although they are not native to this region or physical dimension.

Galactic Core

On some maps the center of the galaxy is regarded as its own area, not part of any of the 4 Quadrants. The Great Barrier is here and within it is "God" (the being encountered by Kirk and company in Star Trek V: The Final Frontier). Also here are the Cytherians from the TNG episode, "The Nth Degree".

Badlands[edit]

The Badlands comprise an area of space that appears (or is referenced) in episodes of Star Trek: Deep Space Nine and Star Trek: Voyager.[1]

Located in Star Trek's Alpha Quadrant, the Badlands are characterized by constant plasma storms and funnel clouds.[1] The Maquis use it in several episodes as a meeting or hiding place because of its treacherous navigation.[1] It is also known to harbor some planets hidden within the clouds and nebulae.

In "Caretaker", the pilot episode of Star Trek: Voyager, the titular starship pursues a Maquis ship into the Badlands before being pushed by an energy wave to the Delta Quadrant.[1]

The Badlands are also mentioned in the computer game Star Trek: Armada II, where the Borg build up forces in that area close to the Federation.

Bajoran Wormhole[edit]

In the fictional Star Trek universe, the Bajoran wormhole is a spatial anomaly located within 160,000,000 kilometres (1.1 au) (DS9 S1Ep2: "Emissary (Part 2)") of the planet Bajor. It appears as an aperture of swirling golden-white light surrounded by blue clouds, which appears whenever a vessel approaches or exits from it and disappears again afterwards. The wormhole can only be traversed by ships traveling at impulse (sub-light speed) velocities.

The Bajoran wormhole is discovered in the first episode of Star Trek: Deep Space Nine. It is found to connect the Bajor-B'Hava'el system in the Alpha Quadrant to the Idran system in the Gamma Quadrant,[2] which are seventy thousand light-years apart. Due to the strategic importance of such a phenomenon, the Deep Space Nine space station is moved out of Bajor's orbit and repositioned 15 kilometres (9.3 mi) from the wormhole, where it acts as a gateway.

Starfleet Commander Benjamin Sisko and Lieutenant Jadzia Dax are the first people to make contact with the wormhole's mysterious creators, who dwell inside it. Though these incorporeal beings are simply referred to as "wormhole aliens" by the Federation, they are revered as Prophets in the Bajoran religion, and the wormhole itself is referred to as the "Celestial Temple". It is these "Prophets" who provided the Orb-like energy artifacts (or "Tears of the Prophets") to the Bajorans, and these mystical artifacts are the basis of Bajoran religion. Via one of the Orbs, the wormhole is closed by one of the Pah Wraiths, which are malevolent non-corporeal beings who are enemies of the Prophets. The wormhole is later restored via an additional Orb discovered by Sisko, who is prophesied to be the Prophets' Emissary.

The Briar Patch[edit]

Regions called the Briar Patch feature in more than one series.

Briar Patch in Star Trek: Insurrection[edit]

The Briar Patch is a nebula in sector 441 in the Star Trek universe. It was first introduced in the 1998 film Star Trek: Insurrection. While the nebula's visual characteristics are reminiscent of astronomical photographs, many of its more interesting properties were invented to support the film's storyline.

Located in Federation territory, the Briar Patch is a region of space that starships usually avoid; various radiation sources and energy fluctuations impair communications systems, making it difficult for vessels inside the nebula to make contact with those outside the nebula. Cloud pockets of "metreon gas", a highly volatile substance of unknown composition, make travel through the nebula difficult as well; warp drives cannot be used, and even impulse drives are undermined.

The planet featured in Star Trek: Insurrection is a class-M world; it is unusual for its possession of an intricate planetary ring system. The Ba'ku have established a colony on the surface, where the colonists rejected most forms of advanced technology and attempted to create a utopian society. Some time after their arrival, the colonists discovered that "metaphasic radiation" from the Briar Patch has become concentrated in the planet's rings, continually rejuvenating their genetic structure; unbeknownst to the outside universe, the Ba'ku planet is effectively a fountain of youth.

Briar Patch in Star Trek: Enterprise[edit]

The Klingon system Klach D'Kel Brakt is also given the designation "Briar Patch" by Dr Arik Soong in the Star Trek: Enterprise episode "The Augments". At least two inhabitable planets exist there;[3] Soong and his band of Augments attempt to reach the system and use it as a hideout. In 2272, it was also the site of a dramatic Romulan/Klingon confrontation, which was led on the Klingon side by the future Dahar Master Kor, who frequently re-enacts the battle with his fellow veterans and Dahar Masters, Koloth and Kang.[4]

Delphic Expanse[edit]

For the episode, see The Expanse (Star Trek: Enterprise episode). For the novel, see The Expanse (Star Trek novel).

The Delphic Expanse, commonly abbreviated as "the Expanse", is the setting for the entire third season of Star Trek: Enterprise, first aired in 2003 and 2004.

The Expanse is about 2000 light years across, surrounded by thick thermobaric clouds. Its edge is located about 50 light-years from Earth. It is the home of the previously unknown hostile races collectively known as the Xindi, but the crew of the Enterprise (NX-01) discovers that the Xindi are being manipulated into their enmity by other forces with vested interests in the region.

Intense gravitational distortions, similar to quantum singularities, make travel through the Expanse extremely difficult, as it seems that space does not obey the known laws of physics in this region. Travelers risk injury, disfigurement, and death if their vessels are not lined with the protective metal Trellium-D.

Species native to the Expanse include the Loque'eque, the Skagarans, the Triannon, and the Xindi.

Featured locations of the Expanse include Azati Prime, the Calindra system, Oran'taku, Triannon, and Xindus.

History of the Expanse[edit]

Thousands of years ago, a number of cloaked spheres the size of small moons were constructed throughout the Expanse by trans-dimensional beings as a prelude to invasion; their purpose was to alter the fabric of space in the region, to make it habitable for the Sphere Builders. One area of the Expanse, 700 million kilometers wide and centrally located within a group of spheres, has already been distorted into a bubbling particle soup with an organic appearance. The spheres use artificial intelligence and operate as a network, with several providing command functions.

Because the spheres are cloaked, their exact number is unknown. Triannons believe that there are thousands of spheres. Xindi scientists, including Degra, determined that there were at least 78 spheres.

The Triannons call the Expanse the "Chosen Realm", and formed a religion around the spheres and the mythology of their creation.

In 2037, a temporally divergent starship Enterprise from 2154 becomes stranded in the Expanse; it becomes a generational ship, dedicated to countering the Xindi threat destined to arise in the 2150s.

In about 2133, a group of Klingons enter the Expanse, but return anatomically inverted (and still alive). Unsuccessful attempts to explore the region are also made by the Vulcan ships Seleya and Vaankara. The Seleya is later discovered with its crew driven mad due to exposure to Trellium-D, and subsequently destroyed.

In about June 2153, the Earth Starfleet ship Enterprise (NX-01) enters the Expanse to locate the Xindi. It is followed later in the year by the Andorian ship Kumari.

On February 13, 2154, the Enterprise destroys the network of Spheres, reverting the distorted space to its natural form, and gradually dissipating the thermobaric cloud barrier. The Expanse thus ceases to exist, becoming a normal, unthreatening region of space.[5]

Although the Enterprise's Captain Jonathan Archer is shown a possible timeline in which the Expanse becomes a major threat to the future United Federation of Planets, this eventuality appears to be eliminated by the successful destruction of the Spheres.

Galactic Barrier and Great Barrier[edit]

In the Star Trek universe, the Galactic Barrier (also referred to as the Great Barrier or Energy Barrier) is an energy field that surrounds the Milky Way Galaxy. The field completely encompasses the galactic disk, preventing a conventional starship from traveling beyond the edge of the galaxy. It is not clear whether the energy barrier is a natural or artificially created phenomenon.

Although numerous attempts to travel outside the galaxy are made, with various degrees of success, the barrier usually damages or destroys ships that try to pass through it. It also has psychoactive effects; some personnel gain powerful telekinetic and telepathic abilities when traveling near the barrier (as seen in "Where No Man Has Gone Before").

The barrier appears as a pink band of light and, upon entering it, a ship is surrounded by dancing clouds of colorful energy. Inside the barrier, a ship's engines shut down and navigational systems become erratic.

The Galactic Barrier makes its first appearance in the original series episode "Where No Man Has Gone Before", in which the crew of the USS Enterprise must deal with those affected by the psychic powers of the field—as did the crew of the ill-fated SS Valiant, which encountered the same barrier two centuries earlier.

The barrier is encountered again in the episode "Is There in Truth No Beauty?", where the Enterprise becomes lost within the barrier and is saved by the astounding navigational skills of an alien passenger.

The barrier had also damaged an alien ship from outside the galaxy, as explained in the episode "By Any Other Name", stranding the aliens until they try to steal the Enterprise and return to their home galaxy, Andromeda.

A second barrier at the core of the Milky Way is first revealed in the motion picture Star Trek V: The Final Frontier. Being the only encounter ever shown, the only known reference is the "Great Barrier". This energy barrier at the core is thought to be impenetrable like the one at the edge of the galaxy; however, it is revealed that only mankind's natural fear of the unknown is keeping mankind from entering it. Non-canonical explanations Various books try to explain the existence of the galactic barrier, although none of these are canonical: The series of novels known as Star Trek: The Q Continuum explain the two barriers, stating that they were created by the Continuum 600,000 years ago, to keep one omnipotent being (known as "The One", which is the same alien encountered in Star Trek V: The Final Frontier) sealed away at the center of the Galaxy, and to keep another (known as "0", whose powers can rival even the Q) locked out of the galaxy forever; this is due to both aliens' previous destructive rampages. In William Shatner's novel Captain's Glory, Picard mentions the events of the Q Continuum trilogy, but states that the barrier was built by the proto-humanoids shown in "The Chase" 4 billion years ago, to protect their "children" (the races they seeded across the galaxy) from a dark matter entity known as the Totality. The novel Q-Squared reveals the Galactic Barrier to be Q himself, in a time-tossed and temporally discorporated state.

Galactic quadrants[edit]

An artistic rendition of the actual Milky Way galaxy, overlaid with one overall view of the fictional quadrant system of the Star Trek universe and the location of certain species. In the original Star Trek, "quadrant" is used interchangeably with "sector". However, beginning with Star Trek: The Next Generation, the term refers to a system of four Galactic Quadrants.

Galactic quadrants within Star Trek are based around a meridian that runs from the center of the galaxy through Earth's solar system,[1] which is not unlike the system of quadrants used by non-fictional astronomers. However, rather than have the perpendicular axis run through the Sun, as is done in astronomy, the Star Trek version runs the axis through the Galactic Center. Also, rather than ordinals, quadrants are designated by the Greek letters Alpha, Beta, Gamma, and Delta.

According to StarTrek.com, "if the great plane of the galaxy is viewed as a clock face and the 6 o'clock position bisects the Sol system"[6] (when viewed from the galactic north pole), then the four fictional quadrants are as follows: Alpha Quadrant is the quarter appearing between 6 and 9 o'clock. Beta Quadrant is the quarter appearing between 3 and 6 o'clock. Gamma Quadrant is the quarter appearing between 9 and 12 o'clock. Delta Quadrant is the quarter appearing between 12 and 3 o'clock.

Alpha and Beta Quadrants[edit]

The Alpha Quadrant and the nearby areas of the Beta Quadrant comprise the primary setting of Star Trek: The Original Series, Star Trek: The Next Generation, Star Trek: Deep Space Nine, and Star Trek: Enterprise. According to the Encyclopedia, the Federation is largely on the Alpha Quadrant side, but with parts in the Beta Quadrant, whereas the Klingon and Romulan Empires are mainly in the Beta Quadrant but extend in part into the Alpha Quadrant.[7] The Star Trek Star Charts have the Romulans and Klingons entirely within the Beta Quadrant, as well as the Gorn Hegemony, the Son'a Solidarity, and the Metron Consortium. The Star Trek Star Charts further locate in the Alpha Quadrant the First Federation, Breen, Ferengi, Tzenkethi, Cardassians, Bajorans, Talarians, and Tholians.

Star Trek VI: The Undiscovered Country implies that the Alpha/Beta border runs through, or is relatively close to, Federation space. The Star Trek Encyclopedia attributes this decision to rationalize a line in Star Trek II: The Wrath of Khan, in which James T. Kirk claims that the Enterprise is the only ship in a quadrant.[7][8] Maps produced by the art staff for the series show that the Alpha/Beta border runs through the Solar system.[9]

The Star Trek Star Charts claim that the Beta Quadrant contains the core worlds Vulcan (40 Eridani), Andoria (Procyon), Risa, and the Rigel (Beta Orionis) systems; the Alpha Quadrant contains Tellar (61 Cygni), Trill, and Betazed.[9]

Gamma Quadrant[edit]

The Dominion, which is the antagonist in the Deep Space Nine series, controls a large portion of the Gamma Quadrant. The Alpha Quadrant comes in contact with the Dominion through the Bajoran wormhole, which is the setting and primary source of conflict in the series.

Delta Quadrant[edit]

Most of the information about the Delta Quadrant and its inhabitants comes from the series Star Trek: Voyager. This quadrant is largely unexplored by the United Federation of Planets, apart from the voyages of the USS Voyager, the USS Equinox, the USS Raven, briefly the USS Enterprise-D, and the Federation citizens assimilated into or de-assimilated from the Borg. The Delta Quadrant is home to the Borg Collective,[10] the Kazon, the Vidiians, the Talaxians, the Ocampa, the Hirogen, and the Malon.

Galactic Core[edit]

On some Star Trek maps of the center of the galaxy, the galactic core is regarded as its own area, not part of any of the four Quadrants. The Cytherians, from the Next Generation episode "The Nth Degree," are located near this area. In Star Trek V: The Final Frontier, a "God"-being is encountered from within what is called the "Great Barrier".

Nekrit Expanse[edit]

The Nekrit Expanse is a vast unpopulated nebular region in the Delta Quadrant, several thousand light years across. It is impossible to chart due to its constantly changing structure. As a result of its size, the Expanse functions as a natural barrier, limiting contact between species on either side of the cloud. The USS Voyager enters the expanse in 2373.[11][12]

Neutral Zone[edit]

In the Star Trek universe, a neutral zone is a sort of "buffer zone" between the territories of two different powers; if either party enters a neutral zone, it is considered an aggressive move (usually an act of war). In the course of the various series, the Federation develops two neutral zones: One with the Klingon Empire and one with the Romulan Star Empire; the generic term "the Neutral Zone" usually refers to the Romulan Neutral Zone. Also, a neutral zone in all but name exists between the Federation and the Cardassians.

Cardassian Demilitarized Zone[edit]

There is a Federation-Cardassian demilitarized zone created at the end of hostilities between the two powers in the mid-24th century. The peace treaty ending the war and subsequent border adjustments result in several Federation worlds within the zone being ceded to the Cardassians. Militant Federation colonists called the Maquis form a guerrilla militia to oppose the treaty and their new Cardassian administrators; they receive assistance from sympathetic Federation citizens, including several Starfleet officers, and from Bajoran veterans of the long Cardassian occupation of Bajor. The DMZ ceases to exist at the outbreak of the Dominion War in 2373; the Maquis are subsequently eliminated as a functional resistance group by a joint Cardassian-Dominion task force.

Klingon Neutral Zone[edit]

The Klingon Neutral Zone, sometimes known as the Organian Neutral Zone, appears to be set up during the time of the Star Trek: The Original Series. Unlike the Romulan Neutral Zone, the Klingon Neutral Zone appears to have some commercial traffic crossing it.

The Organians are non-corporeal beings from the planet Organia IV, which is strategically situated between the Klingon Empire and the Federation. When both parties, thinking the Organians are a pre-industrial people, attempt to occupy their world, the Organians reveal their posthuman nature and impose the Neutral Zone and a peace treaty between the two powers. In Klingon, this treaty is known as orghenya' rojmab (Organian Peace Treaty).

The zone is the site of the Kobayashi Maru scenario in the film Star Trek II: The Wrath of Khan.

The Klingon Neutral Zone is abolished by the Khitomer Accords in 2293.

In Star Trek Into Darkness, set in an alternate reality, the USS Enterprise violates the Neutral Zone to capture Khan Noonien Singh.

Romulan Neutral Zone[edit]

The Romulan Neutral Zone is established around 2160 or 2161 by the treaty of Algeron which ends the Earth-Romulan War, and is still in effect at the end of Star Trek Nemesis. In the 2009 film Star Trek (specifically the events depicted in the year 2387), Romulus is destroyed when a star goes supernova (what effect this has on the neutral zone is unclear). Like the Klingon Neutral Zone, any entry into the region by either party is considered an act of war; this is not violated until 2266, when the Romulans cross it, but a war is avoided nevertheless. The Enterprise (NCC-1701) crosses the Neutral Zone three times: Once to get to a starbase quickly when the crew is suffering accelerated aging, once when it is commandeered by a group of disestablishmentarians in their quest for paradise, and once more when the Federation attempts to steal a Romulan cloaking device.[13]

The Neutral Zone remains uncrossed during a period of extended Romulan isolationism. In 2364, several Federation and Romulan outposts along their respective sides of the Neutral Zone are destroyed by unknown forces. The Enterprise-D is ordered to investigate. While visiting some of the Federation sites, Captain Picard encounters a Romulan ship that has crossed the Neutral Zone. Each side suspects the other of being responsible for the attacks. This encounter between representatives of the Federation and the Romulan Empire—the first in over 60 years—ends peacefully. (These events occur in The Next Generation first-season episode "The Neutral Zone".) It is determined several months later that the destruction was caused by the Borg. The following year, the USS Yamato crosses into the Neutral Zone to prevent the Romulans from finding the Iconian home world, an abandoned planet that contains highly advanced technology. In 2366, the Romulan scout ship Pi crashes just inside of Federation space, and a Romulan ship crosses over to recover survivors. Finally, in the same year, a Romulan defects to the Federation, breaching the Neutral Zone, warning of a secret plan to attack the Federation; the Enterprise-D, along with three Klingon warships, in turn, cross the Neutral Zone to investigate the claim.

Subsequent covert incursions of the Neutral Zone include the Romulans' plan to invade Vulcan using disguised Vulcan ships. An overt but lawful entry into the Neutral Zone occurs when the USS Bellerophon participates in a Federation–Romulan conference on Romulus during the Dominion War.

In Star Trek Nemesis, Shinzon lies that he wishes to take down the zone as part of his ultimately failed plot to destroy Earth and the rest of the Federation.

Sector 001[edit]

Sector 001 is the Federation designation for the area of space that contains the Solar System. The term "Sector 001" is first used in the episode "The Best of Both Worlds".

The engagement between Starfleet and the Borg in Star Trek: First Contact is likewise named the Battle of Sector 001.

Spatial anomaly[edit]

In Star Trek and other science fiction, a spatial anomaly (or, often, a sub-space anomaly) is a broad term for any sort of extraordinary disruption in the space-time continuum. It may take the form of irregularities in gravity, ripples in space that can damage equipment and personnel, alterations in the laws of physics, and areas of disruption inimical to the human brain.

The Delphic Expanse is rife with such distortions generated by spheres which reconfigure space to resemble the Sphere Builders' transdimensional realm.

Other episodes featuring spatial anomalies are "Disaster", which features two quantum filaments that temporarily cripple the Enterprise, the series finale of Star Trek: The Next Generation (in which the USS Enterprise-D encounters a "multiphasic temporal convergence in the spacetime continuum", caused by "an eruption of anti-time"), and "One Small Step" (in which the USS Voyager discovers a rare "graviton ellipse").

For the Star Trek terminology, see Galactic quadrant (Star Trek).

Longitudinal lines of the galactic coordinate system. A galactic quadrant, or quadrant of the Galaxy, is one of four circular sectors in the division of the Milky Way Galaxy.

Quadrants in the galactic coordinate system[edit]

In actual astronomical practice, the delineation of the galactic quadrants is based upon the galactic coordinate system, which places the Sun as the pole of the mapping system. The Sun is used instead of the Galactic Center for practical reasons since all astronomical observations (by humans) to date have been based on Earth or within the solar system.

Delineation[edit]

Quadrants are described using ordinals—for example, "1st galactic quadrant"[1] "second galactic quadrant,"[2] or "third quadrant of the Galaxy."[3] Viewing from the north galactic pole with 0 degrees (°) as the ray that runs starting from the Sun and through the galactic center, the quadrants are as follows (where l is galactic longitude): 1st galactic quadrant – 0° ≤ l ≤ 90°[4] 2nd galactic quadrant – 90° ≤ l ≤ 180°[2] 3rd galactic quadrant – 180° ≤ l ≤ 270°[3] 4th galactic quadrant – 270° ≤ l ≤ 360°[1]

Constellations grouped by galactic quadrants[edit]

Constellations grouped in galactic quadrants (N/S, 1-4)

Quad

NGQ1 7 (Lyra, Hercules, Serpens, Corona Borealis, Ophiuchus, Cygnus, Boötes) NGQ2 8 (Cepheus, Draco, Ursa Minor, Canes Venatici, Ursa Major, Lynx, Camelopardalis, Auriga) NGQ3 9 (Gemini, Cancer, Leo, Canis Minor, Sextans, Monoceros, Pyxis, Leo Minor) NGQ4 12 (Virgo, Libra, Scorpius, Coma Berenices, Corvus, Crater, Lupus, Centaurus, Norma, Crux, Antlia, Vela) SGQ1 11 (Sagittarius, Capricornus, Aquarius, Equuleus, Delphinus, Sagitta, Aquila, Vulpecula, Microscopium, Scutum, Piscis Austrinus) SGQ2 10 (Pisces, Aries, Taurus, Andromeda, Cassiopeia, Cetus, Perseus, Triangulum, Lacerta, Hydra, Pegasus) SGQ3 9 (Orion, Eridanus, Caelum, Lepus, Pictor, Columba, Canis Major, Puppis, Fornax) SGQ4 22 (Circinus, Musca, Telescopium, Triangulum Australe, Apus, Chamaeleon, Corona Australis, Pavo, Indus, Grus, Octans, Sculptor, Phoenix, Reticulum, Dorado, Mensa Tucana, Volans, Carina, Ara, Hydrus, Horologium)

Visibility of each quadrant[edit]

Orientation of the galactic, ecliptic and equatorial coordinate systems, projected on the celestial sphere. Due to the orientation of the Earth with respect to the rest of the Galaxy, the 2nd galactic quadrant is primarily only visible from the northern hemisphere while the 4th galactic quadrant is mostly only visible from the southern hemisphere. Thus, it is usually more practical for amateur stargazers to use the celestial quadrants. Nonetheless, cooperating or international astronomical organizations are not so bound by the Earth's horizon.

Based on a view from Earth, one may look towards major constellations for a rough sense of where the borders of the quadrants are:[5] (Note: by drawing a line through the following, one can also approximate the galactic equator.) For 0°, look towards the Sagittarius constellation. (The galactic center) For 90°, look towards the Cygnus constellation. For 180°, look towards the Auriga constellation. (The galactic anticenter) For 270°, look towards the Vela constellation.

Traditional fourfold divisions of the skies[edit]

[icon] This section needs expansion. You can help by adding to it. (August 2010)

A long tradition of dividing the visible skies into four precedes the modern definitions of four galactic quadrants. Ancient Mesopotamian formulae spoke of "the four corners of the universe" and of "the heaven's four corners",[6] and the Biblical Book of Jeremiah echoes this phraseology: "And upon Elam will I bring the four winds from the four quarters of heaven" (Jeremiah, 49:36). Astrology too uses quadrant systems to divide up its stars of interest. And the astronomy of the location of constellations sees each of the Northern and Southern celestial hemispheres divided into four quadrants.

In fiction[edit]

Star Trek[edit]

See also: Galactic quadrant (Star Trek)

"Galactic quadrants" within Star Trek are based around a meridian that runs from the center of the Galaxy through Earth's solar system,[7] which is not unlike the system used by astronomers. However, rather than have the perpendicular axis run through the Sun, as is done in astronomy, the Star Trek version runs the axis through the galactic center. In that sense, the Star Trek quadrant system is less geocentric as a cartographical system than the standard. Also, rather than use ordinals, Star Trek designates them by the Greek letters Alpha, Beta, Gamma, and Delta.

The Canadian Galactic Plane Survey (CGPS) created a radio map of the Galaxy based on Star Trek's quadrants, joking that "the CGPS is primarily concerned with Cardassia, while the SGPS (Southern Galactic Plane Survey) focuses on Romulans."[8]

Warhammer 40000[edit]

The Imperium of Man's territory in the Milky Way Galaxy in Warhammer 40000 is divided into five zones, known as "segmentums".[9] Navigation in the Milky Way is also identified with cardinal directions, indicating distance from the Sol System: for example, Ultima Segmentum, the largest segmentum in the Imperium of Man, is located to the galactic east of the Sol System.
