The [[Milky Way Galaxy]] is a large barred spiral galaxy that is approximately 100,000 light years in diameter, and contains over 400 billion stars. (ENT: "Azati Prime") 

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's disc is surrounded by a massive energy field of negative energy called the [[Galactic Barrier]], which makes travel into and out of the galaxy difficult. (TOS: "Where No Man Has Gone Before", "By Any Other Name") 

In 2269, the center of the galaxy was explored and found to be a creation point. By 2287, the core had become surrounded by the Great Barrier, containing a planet thought to be Sha Ka Ree by Sybok. (TAS: "The Magicks of Megas-Tu"; Star Trek V: The Final Frontier) 

:'''''In the real world the center of the galaxy is a supermassive black hole called Sagittarius A.''''' 

In the science of stellar cartography, the Milky Way is divided into four major areas called quadrants: [[Alpha Quadrant|Alpha]], [[Beta Quadrant|Beta]], [[Gamma Quadrant|Gamma]] and [[Delta Quadrant|Delta]], each of which compose one-quarter of the galaxy. (TNG: "The Price") 

Between 2064 and 2364, Humans had charted 11% of the galaxy, (TNG: "Where No One Has Gone Before") Within a year, the [[Federation]] had charted an additional 8% of the galaxy. (TNG: "The Dauphin") 

A map of the Milky Way Galaxy was on display in Astrometrics aboard the USS Voyager from 2377 through 2378. (VOY: "Inside Man", et al.) 

Only one out of every 43,000 planets in the galaxy supports intelligent lifeforms. (ENT: "Fight or Flight") 

According to Dr. Leonard McCoy, there is a mathematical probability of three million [[Class M]] planets in the galaxy. (TOS: "Balance of Terror") 

An expedition sent by the Kelvan Empire, from the radiation-imperiled Andromeda Galaxy, scouted the Milky Way for possible invasion in 2268. (TOS: "By Any Other Name")
