The Andromeda Galaxy.

The Andromeda Galaxy was a spiral galaxy located around 2,500,000 light years from the Milky Way Galaxy. The closest point to the Andromeda Galaxy is located in the Alpha Quadrant.

Starfleet Academy: Strategic Command mistakenly claims it is closer to 1,000,000 light years away.


This galaxy was home to a number of alien species which included the Makers who became curious about the neighboring Milky Way galaxy that they desired to explore further. To achieve this end, they created a series of hidden outposts to serve as platforms for further exploration and were populated by androids with one such colony being Galor IV. The androids were responsible for the creation of the pressurized domes and other facilities for their creators but before the Makers could join their androids - their home system went nova thus severing any contact between the Makers and the androids. (Decipher RPG module: Worlds)

For hundreds of years now, the galaxy has seen a rising radiation level which is believed would make it uninhabitable within 10,000 years. One of the local races of the galaxy, the Kelvan Empire, sent several multi-generational ships out to chart nearby galaxies for habitation. One such group arrived in the Alpha Quadrant in 2267 and were encountered by the crew of the USS Enterprise. (TOS episode: "By Any Other Name")

However, Kelvan Commander Rojan's subsequent research turned up alarming facts: that the radiation levels were rising even higher, at an exponential rate, and that the "10,000 years" figure was dangerously optimistic. Thus Rojan argued that the Kelvan Empire should ally itself with the Federation to find a new home for the Kelvans. (TOS - Strange New Worlds 9 short story: "Gone Native")

In the 2270s, the joint entity made of Willard Decker, Ilia and V'Ger headed for Andromeda. (TOS - Star Trek II Short Stories short story: "To Wherever")

In the 2280s, Starfleet had begun to look at exploring the Andromeda Galaxy and sent several long-range starships, including the USS Magellanic Clouds, to investigate. (TOS - Duty, Honor, Redemption novelization: The Wrath of Khan)

Both the Andromeda and Milky Way galaxies are connected by a transwarp corridor which increases the travel speed of transwarp voyages between the void, the USS Monitor during transwarp trials accidentally found its way into this corridor and was stranded between galaxies as a result. (ST novel: Captain's Blood)

The Andromeda Galaxy was destroyed circa 2380 by the Totality. (ST novel: Captain's Peril)

In 2410, the Iconian Herald Dyson sphere jumped from Andromeda to the Milky Way Galaxy. (STO mission: "Uneasy Allies")
