Perseus Arm
The Perseus Arm is a collection of stars, planets, nebulae, and other spatial objects that forms one of many curved "arms" projecting out from the center of the Milky Way Galaxy.

The Perseus Arm seemed to extend a short bit through the Delta Quadrant, a little through the Gamma Quadrant, and extended across the length of the Alpha Quadrant. 

The Perseus Arm was shown on a computer panel in astrometrics on  during the later years of its seven-year journey in the Delta Quadrant. ( display graphic )
