Quadrant

A quadrant is a large volume of space used in galactic cartography.

Milky Way Quadrants

The Milky Way galaxy is divided into four major quadrants 50 000 light years wide, defined by one meridian passing through the calculated center point of the galactic core and a second one perpendicular to the first that also passes through the core. These are called:

• Alpha Quadrant
  
• Beta Quadrant
  
• Gamma Quadrant
  
• Delta Quadrant
  

Andromeda Galaxy Quadrants

The Quadrant convention has also been used by the GA Research & Exploration division to divide the Andromeda Galaxy into similar sections. Due to the larger size of the Andromeda's disk, these quadrants contain a significantly larger quantity of space. They are known as:

• Mu Quadrant
  
• Zeta Quadrant
  
• Omega Quadrant
  
• Tau Quadrant
  

Of these, all but the Omega Quadrant remain entirely unexplored.
