"The Explored Galaxy"
The star chart of the explored space in the Alpha Quadrant depicted the home systems of the three great powers in the quadrant - the Federation, the Klingon Empire, and the Romulan Star Empire. Along with these systems, the home systems of several less significant powers - the Tholian Assembly, the First Federation, and the Kzin - were, also, depicted on the chart. Many of the locations on this map were visited by the USS Enterprise during its historic five-year mission of the late 2260s. Developments in the 24th century, such as the expansion of the great powers into uncharted and charted space, reduced this chart to a historical relic by the 2370s.
In 2293, the star chart of the explored galaxy was displayed in Captain Kirk's quarters aboard the USS Enterprise-A. (Star Trek VI: The Undiscovered Country) The chart was also seen frequently in the 24th century in various locations. In 2364, the chart was displayed at Starfleet Headquarters in the room where Dexter Remmick, possessed by neural parasites, was killed after sending a homing beacon. (TNG: "Conspiracy") In 2365, the chart was seen in the court room on Starbase 173 (TNG: "The Measure Of A Man") and the tactical room aboard the USS Enterprise-D, close to another map that depicted the whole Milky Way Galaxy. (TNG: "The Emissary") In 2367, the chart was seen in the tactical laboratory of Enterprise-D. (TNG: "The Mind's Eye") In 2368, in the ship's engineering laboratory. (TNG: "The Game") In 2369 and 2370, the chart was seen in the classroom aboard Deep Space 9, featuring the heading "The Explored Galaxy". (DS9: "In the Hands of the Prophets", "Cardassians")
