All 168 episodes of Star Trek: Voyager, plotted across the Milky Way from the Caretaker's array to Earth. Every shortcut keeps its full on-screen length. The extra distance goes into the resupply stops, detours, and backtracks the episodes show. Distances come from Memory Alpha; the exact track is an estimate. Compare the 75,000 ly version.
Voyager covers about 85,000 ly to close a 70,000 ly gap. Tap a row to jump to that point in the trip.
Who held the Delta Quadrant
The Borg: one continuous heartland, plus a network that reaches everywhere. Memory Alpha describes Borg space as a vast territory of thousands of solar systems and millions of vessels. In "Scorpion" there is no way around it, only a narrow corridor through it. The Nekrit Expanse was its farthest known border, and it took Kes's 9,500 ly push to clear it. So the core is one block, not islands. After leaving it, though, Voyager met the Borg more often, not less. That's the transwarp network: six hubs and thousands of exit apertures in all four quadrants, with any point reachable in minutes.
Why everyone else survived. Canon gives three reasons:
The Borg are picky. They assess each species and take only those that add to their "perfection". They ignore the rest unless it becomes a threat. The Kazon were rejected as unworthy, and the Brunali only drew attention when they had technology worth taking.
They were busy. The war with Species 8472 was costly, and Unimatrix Zero's resistance came later.
The quadrant is enormous. It holds thousands of species. The network made the Borg a threat everywhere without occupying everywhere.
How big is a power? Canon scale outside Voyager
Canon rarely gives sizes, so the zones are scaled against the few figures that exist. All are from Memory Alpha.
Federation, 8,000 ly across. Picard's figure in First Contact: over 150 worlds spread across eight thousand light years. Memory Alpha notes it might mean volume instead, but the map reads it as distance.
Dominion, the largest zone near Earth. The Founders rule "hundreds of races", which Memory Alpha reads as substantially larger than the Federation. It lies 40,000–50,000 ly from the core, past the wormhole's Gamma terminus.
Klingon and Romulan empires, drawn at about the Federation's scale. No figures are given, but they are its peers. The Klingons once occupied a fifth of Federation space, in 2256–57.
Cardassian Union, smaller. It "never appeared to match the Federation in sheer scale".
Ferengi Alliance, smaller still. Ferenginar is only about 60 ly from Bajor.
Capitals sit close together. Qo'noS is under about 100 ly from Earth, and Cardassia Prime five from Bajor. The great powers meet at a crowded corner and spread outward from it, so the circles show territory, not where capitals are.
For comparison in the Delta Quadrant: at its height, the Krenim Imperium spanned five thousand parsecs, about 16,000 ly. Borg space holds thousands of systems, so it is drawn larger than the Federation.
Sizing the Delta zones. Each zone centres on Voyager's track during that species' episodes. Its radius is the larger of two figures: half the warp distance Voyager flew while in contact, or a floor from what canon says about the species:
Where episodes say Voyager skirted a border, as in "Deadlock" and "Nightingale", the zone is set off to one side of the track. When a species appears in two far-apart places, it gets two zones.
The transwarp network vs. the "Endgame" map
In "Endgame", Seven's astrometrics display shows the Borg transwarp network as cyan conduits across the whole galaxy, with four hubs. Memory Alpha notes this is four of the six hubs mentioned in dialogue, one in each quadrant. Dialogue gives thousands of exits in all four quadrants. The cyan layer here follows that layout: one hub per quadrant, plus a generated sample of the conduits. Comparing it with the old version of this map and with the on-screen graphic:
Scope. The old map showed only the hub Voyager used and a few Borg sightings, which badly understated the network. The graphic shows the Borg can reach practically anywhere, including just outside Federation space. That is how the Battle of Sector 001 and the aperture less than a light year from Earth come about.
Hub placement. In the graphic, the hubs sit roughly a third to four-fifths of the way out from the core. Here the Delta hub, Grid 986, sits right at the core's edge, because the dialogue puts it about 30,000 ly from Earth. The graphic is a schematic, so the dialogue wins, but the two disagree by tens of thousands of light years. The other three hubs follow the graphic.
A canon contradiction. Admiral Janeway says there are only exit apertures in the Alpha Quadrant, yet the graphic shows a hub there. Memory Alpha flags this too. The map follows the graphic and labels it.
Orientation. The frame shows quadrant boundaries but no labels, so its rotation can't be matched exactly. Memory Alpha's own quadrant diagram puts Alpha upper-left. This map puts Earth at the bottom, which is the same arrangement rotated a quarter turn.
After "Endgame". Voyager's torpedoes collapse the network, so at the last episode the cyan layer fades and is marked destroyed.
How the route is built
Shortcuts keep their stated length. Some reached home less than their length suggests. Night's vortex covers 2,500 ly, but Memory Alpha's 2375 page counts it as 2,000 ly closer. Dark Frontier's coil covers 20,000 ly but saves only about fifteen years. Those jumps are drawn curving off the homeward line, so the line is the full length but the net gain matches the time saved.
Turning years into light years: Janeway's original projection was 75 years for 70,000 ly, about 933 ly per year. That converts "ten years off the trip" into roughly 9,300 ly of net progress.
Seasons 1–4 have a canon odometer. In "One", Janeway says they've come 15,000 ly, at a nebula 60,000 ly from Earth. Kes's push accounts for 9,500 ly, which leaves 5,500 ly of warp travel for only 500 ly of net progress. The other 5,000 ly is detours.
Later stretches use the same average pace (about 60 ly per episode). Each stretch is fit between canon fixes: 60,000 ly ("One"), just over 30,000 ly ("Pathfinder"), and 30,000 ly at Grid 986 ("Endgame").
Sharing out the detour distance: episodes that show a resupply stop, side trip, or backtrack get three times the travel of an ordinary episode, and little or negative net progress. Episodes where the crew picks a faster route ("The Swarm", "One") get extra net progress. The exact zigzags are generated, not canon. Switch to the Close view to see them.
Q's shortcut in "Q2" is a route Janeway was handed, and "Endgame" arrives before it could pay off. The map adds no jump for it.
The start is disputed. Memory Alpha's ship article says 70,000 ly. Its 2371 page says 75,000 ly. With 75,000, "One"'s 15,000 ly traveled and 60,000 ly remaining line up exactly, and seasons 1–4 would need no detours. This map uses 70,000.
The galaxy: Earth sits on the Alpha/Beta line about 30,000 ly from the core, Memory Alpha's figure for Federation space. That puts Grid 986, just over 30,000 ly from Earth, right at the edge of the galactic core. Grid 986 is near the Delta/Beta boundary. The spiral arms are illustrative, and landmarks are placed by episode order, not canon coordinates.
Borg reach
One category, two levels of evidence. Borg-controlled territory is now one category, "Borg reach". The bright, solid glows are canon: the heartland Voyager crossed in "Scorpion", and Species 116's assimilated world. The fading circles around each transwarp hub are inferred. The Grid 986 circle is anchored by the 47+ cubes that canon puts there. The Unicomplex counts as Borg reach too, but canon never says where it is, so it isn't drawn.
Held core (dashed ring, 2,500 ly). Hubs are the network's most valuable assets. Memory Alpha says the Grid 986 hub's nebula held at least 47 cubes. The map assumes every hub is guarded the same way.
Raiding reach (fading circle, 14,000 ly). This is roughly how far conduits fan out from each hub on the "Endgame" map before thinning out. Within it, a cube can arrive in minutes, so any species worth assimilating is exposed.
Checking it against canon Borg sightings (green ✕):
Delta hub: strong support. Almost every Borg encounter in seasons 6–7 falls inside it. These include the Borg children's derelict cube, the Brunali homeworld under a light year from an aperture, Unimatrix Zero, the debris in "Imperfection", and Grid 986 itself.
Beta hub: moderate support. System J-25 sits about 7,000 ly from Federation space, where Q first showed the Enterprise the Borg in 2365. That falls within this hub's reach on the map, but J-25's direction is never given, so the placement is schematic.
Alpha hub: contested. The graphic shows a hub here. Admiral Janeway says the Alpha Quadrant has only exit apertures.
Gamma hub: weak support. No Borg activity there is mentioned in DS9 or the Dominion stories. The Dominion may simply never have been judged worth the effort, or the hub was far from Dominion space.
Earth's own encounters fall outside every reach circle. These are the Neutral Zone outposts (2364), Wolf 359 (2367) and the Battle of Sector 001 (2373). They came by long warp journeys or single conduit exits like the one under a light year from Earth, not from a nearby hub. That fits the canon picture of the Alpha Quadrant as a raiding target rather than held territory.
What it suggests. The Borg may hold four or more fortified islands, not just one Delta Quadrant heartland, each with a raiding radius larger than the Federation. Even so, these zones together cover well under half the galaxy, consistent with the Borg being selective rather than everywhere at once. The two hubs missing from the "Endgame" map would add more, in unknown places.
