Star Trek Map Of The Alpha & Beta Quadrants

The map above is Shakaar’s Alpha/Beta map v3.3; a fan-made creation showing the Alpha and Beta quadrants of the Star Trek universe.

The map shows both major and minor powers that have appeared in the various series over the years.

At the centre is the United Federation of Planets, which borders the major power of the Klingon Empire, Roman Star Empire and the Cardassian Union. More minor powers include the Breen, Ferengi Alliance, Tholian Assembly, Sheliak Corporate and the Gorn Hegemony among many, many others.

The map highlights:

• Principal Systems
• Minor Systems
• Non-Aligned Systems
• Dead Systems
• Government Borders
• Points of Interest
• Navigation Hazards

Okay so Xindus by Vulcan…. kys I’m not even gona bother looking further don’t make a map if you don’t know what your talking about

Romulons should have Dyson sphere (at least at Romulus and Remus). Their ship tech is based on creating black holes which will give a ship a reactor core with a life of a handful of years BUT it’s just like an inefficient battery because it takes way more energy to initially create it then it will give off over its life BUT it’s portable. Sure beats light sails if your depending on home system energy and way more flexible too. This was their tech wheelhouse, and was their interstellar travel energy source instead of antimatter. It makes total sense for them to have harnessed the majority of their native suns energy to create reactor cores wherever they needed a portable energy that couldn’t tap into the system wide grid.

February 22, 2019 at 9:26 pm

A few questions… 1) Why are there several Indus VIII on the map?, 2) I do not see the First Federation on this map — they should be near the Ferengi!, 3) Where is the Kelvin planet? (The planet colonized by the Kelvins from “By Any Other Name”), 4) Maybe I’m wrong, but I do not see the Dyson Sphere that TNG crew ran into?

Not your fault, I know;

Vulcan is “Supposed” to be “A little over sixteen” light years from earth. Yet the map has it at around 1000. That’s one of my biggest gripes about Star Trek (I absolutely love Star Trek, don’t get me wrong). Distances and travel times are so inconsistent and unrealistic based on the documented scales, maps, etc.

March 14, 2020 at 11:46 pm

Did you mean Starbase 375 instead of 395? As in the starbase from S6 of DS9 after the Dominion took over the station?

Avro Arrow says

I love this map, especially how you have the Hydran Kingdom, the Lyran Star Empire and the Kzinti Hegemony are listed (where is the Interstellar Concordium?). I have one small nit-pick to make and that is you have two systems named “Nelvana III”. They’re both in the upspin Beta quadrant but one is in the Romulan Neutral Zone and the other is further upspin and outward (left). I think that you might consider making most of the empty space that is coreward of Klingon and Romulan space into the ISC. They were referred to as being a Galactic Superpower residing on the far side of both those Empires (so, coreward).

I dont understand how this can be called a map of the star trek galaxy when there isnt even a spot or indication of where earth is. Who makes a map without earth when you have a series where its location is based on earth. In the series they refer to Earth as Earth. Yet the closes thing to it is on the map is Volcan. Y not add Earth as well? If there is an alternative name how come it’s never mentioned in the shows and a secret for fans?

Brandon says

August 15, 2020 at 4:14 pm

Earth is 100 percent there. It’s Sol. It’s a common alternate name for our star system and has been used in Trek.

February 8, 2021 at 3:26 pm

Sol system. The Greek word for sun. Follow the bold line and look for the team Terran and Vulcan sectors. Sol is on the 4 corners there

Issues: Tykens rift, not Titans. Starbase 47 is about 10 sectors off as memory Beta says it is located between the Tholian assembly and the Klingon empire. Prophets Landing is in the gamma quadrant.

Screen Rant

Star trek's 4 quadrants & galaxy explained.

Along with the Milky Way Galaxy's quadrants, the Star Trek universe encompasses galactic barriers, further galaxies, and even a mythological core.

Most of the action in Star Trek takes place in the real-world Milky Way Galaxy which is roughly divided into four quadrants, named after the first four letters of the Greek alphabet: Alpha, Beta, Gamma, and Delta. These are the galactic regions that include significant planets like Vulcan, Qo'noS, and of course, Earth. While Gamma and Delta still bear planets with ominous origins, the Alpha and Beta Quadrants are perhaps touched upon the most within the Star Trek mythos. Despite this common division, The Next Generation also referred to a new quadrant known as Morgana. But not much is known about this certain quadrant as it is not mentioned any further.

Even beyond the Quadrants, ardent Star Trek fans can spot the Galactic Barrier and several other celestial objects that are present in other galaxies like the Andromeda Galaxy (yet another real-world phenomenon) that are still yet to be explored more by the franchise's protagonists. While most of these galactic quadrants can be seen as astronomical phenomena rooted in scientific explanation, the mythos can also incorporate near-godly beings like the Sha Ka Ree in regions such as the so-called "Great Barrier." The two Barriers carry within them such heavenly mysteries that deserve explanations of their own.

TOS Invented Star Trek's Best Time Travel

Alpha Quadrant

The Star Trek galaxy explained that the Alpha Quadrant contains more than 60 home worlds, and this includes Captain Kirk's home planet Earth itself (which Trekkers would call Terra or Sol III). Other major planets include the Tellarite native planet Tellar Prime, Trill, which houses both the eponymous humanoid species and the non-humanoid Trill symbionts, and Betazed, which is inhabited by the Betazoids, a humanoid species that boasts warp-capable space vessels. Even though the majority of territories under the Klingon Empire and Romulan Star Empire fall in the Beta Quadrant, the two forces join the United Federation of Planets and the Cardassian Union to constitute the four great powers in the Alpha Quadrant in the late 24th century.

Beta Quadrant

The Star Trek galaxy explained that apart from the Romulans and the different versions of the Klingons , the Beta Quadrant's highlight is Vulcan, the native planet of Spock and other members of the Vulcan species. Multiple Star Trek encyclopedias suggest that Vulcan is located in a Sector of the same name within the Beta Quadrant. The 2002 publication Star Trek Charts also estimates Vulcan's exact position to be somewhere in the 40 Eridani star system that really exists 16.3 light years from Earth's Sun. Much like Spock, the inhabitants of Vulcan can be identified with their raised eyebrows and pointy ears. Mostly devoid of emotions, the Vulcans are known for leading a life on the basis of logic and reasoning.

The Klingon homeworld Qo'noS and the Romulan Empire's native planet Romulus also fall under this galactic quadrant. The former has a chaotic weather system with frequent thunderstorms and a rocky landscape characterized by numerous dormant volcanoes and caves. The native warrior species of Klingon are bound by their martial traditions and value honor in combat. As for Romulus, the planet served as the second home for Romulans ever since they migrated from Vulcan. The biological cousins of the Vulcans, they had to move back to their original homeworld after Romulus' sun exploded in 2387. According to The Next Generation , Risa is also a part of this quadrant. Known as the pleasure planet, Risa is known for its sexually liberated culture.

Gamma Quadrant

The Star Trek galaxy explained that the Gamma quadrant includes several Star Trek planets such as Brax, Yadera, Meridian, and others. As seen in Deep Space Nine , the Quadrant also houses the Dominion, an aggressive ensemble of several alien species commanded by the shape-shifting Changelings (AKA the Founders). Several territories of the quadrant are under the Founders' control even though they have had only two home worlds. The first home world of the Founders was a rogue planet that housed the Founders who were, at that time, escaping prosecution from the "solids" (how they referred to non-shape shifters). By 2372, the Founders shifted to a second home world.

Delta Quadrant

The Star Trek galaxy explained that Star Trek: First Contact confirms the origin of the Borgs from Delta but doesn't name their home planet. This is the case for many other species of Delta, a quadrant that is relatively unexplored by the United Federation. Only Voyager offers the most details about the planets within the quadrant. Delta is also known as the domain of antagonistic species like the Borgs, the Kazon, and the Vidiians. The cybernetic Borgs are mostly linked through a hive mind known as the Collective. As for the Kazon, they are nomadic in nature which makes it difficult to trace their planet. Vidiians are similarly migratory and sport-scarred faces as a result of the terrible Phage pandemic.

The Galactic Barrier

The Star Trek galaxy explained in the original series what is known as Star Trek 's Galactic Barrier . In the subsequent years, Trekkers have called it by many names ranging from Great Barrier to the Energy Barrier, but there is still much debate and discussion regarding the origin of this energy field that surrounds the Milky Way Galaxy. The origins behind its creation are still hotly debated so it is uncertain whether the Galactic Barrier was created by a natural process or by artificial means. Most of the conventional spaceships that have tried crossing this barrier in the Star Trek universe have often been destroyed with the crew even gaining psychoactive traits while nearing the barrier.

The Andromeda Galaxy

Progressive exploration of the Star Trek galaxy explained that the Milky Way Galaxy is definitely not the final frontier , as several other galaxies lie beyond it, such as the Andromeda Galaxy. This serves as a home for the planet Kelva, the capital of the Kelvan Empire. The Kelvans are highly intelligent shapeshifters. Because of their intellectual superiority, the Kelvans feel that it is their duty to rule over other species. The same galaxy also includes the humanoid species simply known as the Makers, creators of service robots and outposts in both the Andromeda and Milky Way Galaxy. The outposts were a residential necessity given how a supernova had destroyed their homeworld.

The Extragalactic Species

The Star Trek galaxy explained that the spanning areas of planets and species that border Star Trek 's Galactic Barrier from the galaxies beyond the Milky Way are still vague in Star Trek canon. Still, some information has been obtained on a few humanoid and non-humanoid extragalactic species. Species 10-C is a major case in point. A highly-advanced non-humanoid race with members much larger than humans, the species is responsible for creating the heavily destructive Dark Matter Anomaly. With their bodies adapted to float in gas layers, Species 10-C belong to a homeworld near the Galactic Barrier. Other such examples of extragalactic species include the "space amoeba" Nacene, the physically fragile Ornithoid, and immortal races like the Q and the Douwd.

The Center Of The Galaxy

Star Trek V: The Final Frontier reveals the presence of the mythological planet Sha Ka Ree right at the center of the galaxy that doesn't fall under any quadrant. An equivalent of the concept of heaven, Sha Ka Ree is regarded in Vulcan mythology as the realm of all creation. But owing to humankind's fear of exploring the unknown and the second Galactic Barrier, the exact physical nature remains unexplored and is regarded as a mythical entity. It goes to prove how the mysteries of Star Trek 's chief galaxy don't just go beyond its exterior but its very core too.

Multiple Alternate Realities And Timelines

Not only is there several quadrants, but the Star Trek galaxy explained that there are also several alternate timelines in the franchise's world. In the Paramount+ series Picard , there is an alternate reality that completely rewrites Star Trek's history . The movies, from the original series to the Next Generation, take place in what is known as the Prime Universe. The J.J. Abrams movies take place in what is known as the Kelvin Timeline.

Abrams showed this in his movies by having the Kelvin Timeline Spock meet a Spock from a different timeline. This allowed Star Trek to move on with any story it wanted to tell by explaining the characters are from different timelines with new and fresh histories. There is also a Mirror Universe, an alternate timeline ruled by the fascist Terran Empire instead of the Federation. With so many quadrants, they all likely ended up very different in each timeline, making the Star Trek stories endless.

A Wannabe Blue Shirt Officer’s Guide to the Map of the Galaxy in ‘Star Trek’

No matter the fictional universe— be it fantasy or sci-fi or somewhere in between (looking at you, space operas)—I’ve always found maps and cartography one of the most fascinating parts of worldbuilding. There’s something about actually seeing how an author imagines the setting of their story that immediately grounds it in the realm of possibility, and helps immerse viewers in the worlds in which these stories unfold.

Sure, it’s somehow easier when the map consists of a single continent, kingdom, or city on Earth or any other Earth-like location. Bringing the action up into space definitely makes everything a tad more complicated—and a whole lot more fascinating. 

And now that the third season of Star Trek: Picard is in full swing , there’s no better time to refresh our collective memory on the “astrogeography” the crews of the USS Enterprise explore.

Star Trek and maps

The decades that have passed since Star Trek first premiered on television screens have made it possible for the saga to acquire beautifully complex and detailed lore on pretty much everything related to it—including the planets that make up the United Federation of Planets, and the powers that border it, like the infamous Klingon Empire.

There have actually been several maps made for Star Trek and its locations over the years, as it reads on The Map Room blog . “While original series canon assigned aliens to known nearby stars, and the shows occasionally used real locations, episode writers did not start with a map and generally did not take spatial relationships into consideration, which no doubt has made the belated mapping process a bit more challenging,” The Map Room blog continues, explaining how creating a comprehensive map of the Star Trek galaxy might be easier said than done.

Still, while none of the maps ever put to print or screen have ever been accepted as official canon, most of them have the major power players of the galaxy in more or less the same location. This means we can reasonably assume that this is the actual position in which they can be found in-universe. 

The galaxy quadrants

Most of the action in the Star Trek canon takes place within our galaxy, the Milky Way, which has been divided into its famous four primary quadrants, each named after a letter in the Greek alphabet: Alpha, Beta, Gamma, and Delta.

The Alpha and Beta quadrants are the ones that are better known, even in-universe, and that house many of the major players we see throughout the various series—the United Federation of Planets chiefest of all. The Federation has a strong foothold in both quadrants, spanning Alpha and Beta from their shared border outwards. 

According to Memory Alpha , the official Star Trek fan wiki, the Alpha quadrant contains two all-important planets that we all know very well: Earth, from which a good majority of the characters in Star Trek canon hail; and Vulcan, the homeworld of the Vulcans and especially of Spock. This quadrant also contains the Cardassian Union, the Ferengi Alliance, and the Breen Confederacy—among other smaller factions—whose representatives make an appearance in the canon, particularly in Star Trek: Deep Space Nine .

The Beta quadrant includes a couple of relatively smaller players like the Nyberrite Alliance and the Tholian Assembly, and then the major forces of the Romulan Star Empire and the infamous Klingon Empire—who both have their respective homeworlds, Romulus and Qo’noS, in this quadrant.

In contrast to the Alpha and Beta quadrants, the Gamma and Delta quadrants are considerably less well-known and less visited—which makes sense, considering the notable distances that separate them from the other areas of the galaxy, which would require years to bridge even at warp speed. Their reputation also isn’t as stellar as the areas in Federation space.

Still, they are of course mentioned time and again in the canon, as are the planets and people located within them. The Delta quadrant, for example, is the place of origin of the infamous Borg Collective, made up of the terrible Borg cyborgs.

The Map Room

Mapping Star Trek

This month marks  Star Trek ’s 50th anniversary, so I thought it might be worth it to put together a little post about maps in  Star Trek . This proved to be more fraught a subject than I expected. There are a lot of maps of the  Star Trek universe out there by divers hands, some more official than others, and they don’t always agree on all points,  as Sufficient Velocity forum member WhiteDragon25 griped in 2014 :

Despite so many planets, stars, systems, and other locations that were mentioned and referenced to throughout the entire franchise’s run, we’ve never got an official and fully accurate map of the Trek universe. […] Hell, for all of the Star Wars EU’s faults, at least it managed to generate a  universally accepted map!  Star Trek on the other hand, despite being  just  as popular as Star Wars, cannot even figure out the sizes and positions of the Feds, the Romulans, and the Klingons in relation to one another!

WhiteDragon25 might be overstating things a bit: most of the maps have the  Star Trek major powers in the same relative position (other empires like the Tholians are another matter). But the point remains. While original series canon assigned aliens to known nearby stars, and the shows occasionally used real locations (e.g. Wolf 359 ), episode writers did not start with a map and generally did not take spatial relationships into consideration, which no doubt has made the belated mapping process a bit more challenging.

In print form, the earliest map I’m aware of is  Star Trek Maps (1980), which according to Memory Alpha was a pair of double-sided map posters accompanied by a fairly mathy booklet; of course, the Star Trek universe was a lot smaller then.  Star Trek: Star Charts came out in 2002 and seems to be considered the most canonical of the maps in existence; it’s out of print now, though.  Star Trek: Stellar Cartography (2013), a collection of ten 24″×36″ folded maps. (Note that I haven’t seen any of these maps.)

Online, Star Trek Dimension’s Cartography section has maps from the series as well as Christian Rühl’s Galactic Atlas .  StarTrekMap.com , a fan site that appears to be based on Star Trek: Star Charts , uses an in-universe interface that functions well (scroll wheel zooming!) but is awfully small on large screens. Neither has been updated in years. The Star Trek Online game also has, as you might expect, a map .

Alpha/Beta Quadrant Overview star chart

The star chart following the Klingon takeover

The Alpha/Beta Quadrant Overview star chart was first seen in 2256 , in Captain Lorca 's quarters aboard the USS Discovery , as well as at Lieutenant Rhys 's station on the bridge. It displayed the location of the Discovery near the Federation-Klingon border during the Federation-Klingon War of that year .

It shows the locations of the Alpha Quadrant systems Aldebaran (Alpha Tauri), Amar , Andoria , Azha (Eta Eridani), Ba'ku , Beta Leonis Minoris ( Beta XII-A ), Beta Rigel , Castor (Alpha Geminorum), Coridan (Chi 1 Orionis), Deneva (Kappa Fornacis), Elora , Orion , Organia , Pollux (Beta Geminorum), Risa (Epsilon Ceti), Son'a , Tarlac , Tellun ( Elas Troyius ), Vulcan , Zibal (Zeta Eridani), and 11 Leonis Minoris , as well as the Briar Patch , Sherman's Planet , and Starbase 12 (Gamma 400). Amar, Organia, and Sherman's Planet are indicated to have been Klingon Empire territory at the time.

Beta Quadrant systems on the Federation side of the border include Acamar (Theta Eridani), Adelphous , Ajilon ( Tananda Bay ), Alpha Onias , Barolia (Wazn, Beta Columbae), Beta Pictoris , Carraya , Celes (Tau Hydrae), Chi Leonis , Galorndon Core , Gamma Hromi , Hyralan (Alpha Caeli), Japori (Beta Caeli), Jouret (New Providence), Miridian , Omega Leonis , Ramatis , Regulus (Alpha Leonis), Tomed , Unroth , Xarantine (Zeta Leporis), and Yridia . Landmarks on the Federation side include the Azure Nebula , Deep Space Station K-7 , the Hromi Cluster , the Paulson Nebula , Starbase 23 , Starbase 24 , Starbase 157 , Starbase 234 , and Starbase 343 .

Beta Quadrant systems on the Klingon Empire side of the border include Archanis , Archer , Ardana (Rasalas, Mu Leonis), B'Moth , Balduk , Beta Lankal , Beta Penthe (as Rura Penthe ), Beta Thoridor , Brestant (Delta Laporis), Cursa (Beta Eridani), D'deridex , Dewa , Dinasia , Gamma Eridon , Ganalda , Gasko , Gorath , H'atoria , Halee , Iccobar , Iconia , Ikalia , K't'inga , Khitomer , Klach D'kel Brakt , Korvat (Pi Canis Majoris), Krios , Lambda Geminorum , Mempa , Morska , Narendra , Nequencia , No'Mat (Omicron Leonis), Pheben , Praxis , Qo'noS (Kronos, Kling), Qu'Vat , Tranome Sar , and Valt . The star Archanis is right on the border, while Gasko and Korvat are shown as being under Klingon control, but on the Federation side of the border. Archanis and Korvat are on the Klingon side of the thinner dotted line, however.

The star chart of the explored space in the Alpha and Beta Quadrants depicted the home systems of the three great powers in the quadrant – the Federation, the Klingon Empire , and the Romulan Star Empire . Along with these systems, the home systems of several less significant powers – the Tholian Assembly , the First Federation , and the Kzinti – were, also, depicted on the chart. Many of the locations on this map were visited by the USS Enterprise during its historic five-year mission of the late 2260s . Developments in the 24th century , such as the expansion of the great powers into uncharted and charted space, reduced this chart to a historical relic by the 2370s .

In 2293 , the star chart of the explored galaxy was displayed in Captain Kirk 's quarters aboard the USS Enterprise -A . ( Star Trek VI: The Undiscovered Country )

The chart was also seen frequently in the 24th century in various locations. In 2364 , the chart was displayed at Starfleet Headquarters in the room where Dexter Remmick , possessed by parasitic beings , was killed after sending a homing beacon . ( TNG : " Conspiracy ") In 2365 , the chart was seen in the court room on Starbase 173 ( TNG : " The Measure Of A Man ") and the tactical room aboard the USS Enterprise -D, close to another map that depicted the whole Milky Way Galaxy. ( TNG : " The Emissary ") In 2367 , the chart was seen in the tactical laboratory of Enterprise -D. ( TNG : " The Mind's Eye ") In 2368 , in the ship's engineering laboratory . ( TNG : " The Game ") In 2369 and 2370 , the chart was seen in the classroom aboard Deep Space 9 , featuring the heading "The Explored Galaxy".
