Milky Way

Quadrants of the Milky Way.

The Milky Way Galaxy is a large barred spiral galaxy that is approximately 100000 light years in diameter, and contains over 400 billion stars. The galaxy is composed of three major parts: the core, the disc, which is the ring of stars and interstellar dust that gives the galaxy its spiral shape, and the halo, which includes many older stars orbiting the core, but outside the disc, of which most are concentrated in massive globular clusters.

The Milky Way is conventionally divided into four galactic quadrants. Since the Milky Way has a diameter estimated at about 100000 light years, we can deduce that each quadrant will have a diameter of about 50000 light years.

An outline of the galaxy can be seen in the following table:

Alpha Quadrant

Is between 0º and 90º. In this quadrant are the Earth, Teremedó and Gobola. But according to this subdivision the Earth is exactly on the border between the Alpha and Beta quadrants, about halfway from the center of the Milky Way.

Beta Quadrant

Is between 0º and 270º. The Earth is on the border of Alpha and Beta quadrants. In this quadrant live the Klingons, the Romulans, the planet Vulcan (which were made ​​by the first contact with humans), the Talos system (Nimbea and Mira) and the Tekoda Center. Note that the Romulans and the Klingons extend most of the Alpha quadrant.

Gamma Quadrant

It lies between 90º and 180º, is the seat of the Dominion (aka twilight zone), which exerts a tight control over almost the entire quadrant. In this quadrant are a wormhole, connected to the Alpha quadrant. Much of this quadrant is unexplored.

Delta Quadrant

Is between 180º and 270º. It is the seat of the Borg (who dominate the quadrant). This quadrant is also unexplored.


It can be seen in broadly a political division of the galaxy according to the following scheme, the most important powers are the Dominion, the Borg, the Klingons, the Romulans and the secret Federation Starfleet.
