Gamma Quadrant

The Gamma Quadrant is the common designation for one-quarter of the Milky Way Galaxy. Its boundary is defined by a meridian passing through the galactic core and the Sol System, and a second meridian 90º perpendicular at the core. Its closest point to Earth is located approximately 30,000 light-years away. However, the stable Bajoran wormhole links the Idran system in the Gamma Quadrant with the Bajoran system in the Alpha Quadrant.

An important navigational star in this quadrant is M92.

It is believed that the Hur'q originated from the quadrant.

The quadrant was first explored by the Federation's Quadros-1 probe in the 22nd Century.

A large portion of the Gamma Quadrant is under the control of the Dominion, but it is believed that some minor powers exist on the fringes of their space.

The archaeologist Vash explored the Gamma Quadrant for two years at the invitation of Q in 2367. She was found here in 2369 by members of Deep Space 9's crew.

The Vulcans were at the forefront of the exploration of the Quadrant, beginning only months after the wormhole was discovered by Benjamin Sisko and Jadzia Dax in 2369. Within three years, the Vulcans made many discoveries, including the remains of the Hur'q race.

The Klingons showed interest in explore the Gamma Quadrant shortly after its discovery by sending its own scout ships to the Quadrant. The IKS Toh'Kaht was among the first ships to explore the Quadrant in effort to establish colonies on the other side of the wormhole.

On the other hand, no Romulan ship had ever been to the Gamma Quadrant until late 2371 during their abortive attack on the Founders' homeworld.

In an act that started the Dominion War, the Federation mined the entrance to the wormhole leading to the Gamma Quadrant in 2373. This cut off access to this quadrant from any Alpha Quadrant powers and prevented Dominion reinforcements from adding to the war.
