G is for Gorn

The Gorn's first contact with the Federation took place in 2267, when the Gorn attacked a Federation colony on Cestus III. The Gorn saw the strike as a preemptive move, since they regarded the Cestus system as part of their territory. The USS Enterprise pursued a Gorn starship from Cestus III into a previously unexplored region of the galaxy, near 2466 PM. There, both starships were immobilized by the Metrons, who transported James T. Kirk and the Gorn captain to a planet's surface, where the two captains were instructed to settle their differences in a "contest... of ingenuity against ingenuity, brute strength against brute strength."

F is for Federation

"A dream that became a reality and spread throughout the stars." – James T. Kirk, 2269

The United Federation of Planets (abbreviated as UFP and commonly referred to as the Federation) was an interstellar federal republic, composed of planetary governments that agreed to exist semi-autonomously under a single central government based on the principles of universal liberty, rights, and equality, and to share their knowledge and resources in peaceful cooperation andspace exploration.

One of the most powerful interstellar states in known space, it encompassed 8,000 light years. The total number of formal member worlds was over one hundred and fifty.

E is for Enterprise

The USS Enterprise (NCC-1701) was a 23rd century Federation Constitution-class starship operated by Starfleet. In the course of her career, the Enterprise became the most celebrated starship of her time.

In her forty years of service and discovery, through upgrades and at least two refits, she took part in numerous first contacts, military engagements, and time-travels. She achieved her most lasting fame from the five-year mission (2265-2270) under the command of James T. Kirk.

D is for Dilithium Crystals

Dilithium, also known as radan, is an element, a member of the hypersonic series, mostly occurring as crystalline mineral. It was used to control the power of the warp drive systems of many starships by regulating the matter/antimatter reaction in a ship's warp core because of its ability to be rendered porous to light-element antimatter when exposed to high temperatures and electromagnetic pressures. It controlled the amount of power generated in the reaction chamber, channeling the energy released by mutual annihilation into a stream of electro-plasma.

C is for Cookie

It's not the kind of cookie you're thinking of, though. See those dark, shadowy lines on the wall behind Scotty? Those are made by using a cuculoris, or, as it's called in movie-making slang, a cookie. 

In lighting for film, theatre and still photography, a cuculoris (occasionally also spelled cucoloris, kookaloris, cookaloris or cucalorus) is a device for casting shadows or silhouettes to produce patterned illumination. The word is sometimes shortened to cookie or coo-koo. The cookie is used to create a more natural look by breaking up the light from a man made source. It can be used to simulate movement by passing shadows or light coming through a leafy canopy.

Here's another shot - see the shadowy lines in the doorway in the back? 

Star Trek was famous for its use of wagon wheel shaped cookies. Pay attention the next time you catch an episode!

B is for Balok

During a mission, the Enterprise encountered an immense, highly sophisticated space vessel, the Fesarius, and its commander, Balok. Balok's appearance eventually yielded to Spock's determined efforts: a bluish, cat-eyedalien in an eerily-lit control center that wavered and rippled.

Balok condemned the crew as warlike because they had been forced to destroy a marker buoy. In fact, he had forced their hand, goading and threatening them with the device. Then, he advised the crew that they and their vessel, "obviously the product of a primitive and savage civilization," were to be destroyed.

A is for Andorian

The Andorians were a humanoid species from the moon Andoria, capital of the Andorian Empire. In 2161, their homeworld became a founding member of the United Federation of Planets.

Most Andorians were blue-skinned with white or silver hair. An Andorian subspecies called the Aenar had white skin and, unlike blue Andorians, were blind and telepathic. Andorians and Aenar were genetically compatible and could produce offspring.
