Anti-Matter
Warp drive depends on a warp core based reaction between Matter (Deuterium) and Anti-matter (Anti-Deuterium) to go to faster-than-light speed. Anti-Matter has a negative charge but has the same mass and size as Matter, which has a positive charge.

Alpha Quadrant
An area of the Milky Way which is the home of worlds such as the Federation, Betazed, Ferengi, the Cardassian Union, Bajor and the Bajoran wormhole, which bridges a 70,000-lightyear shortcut to the Gamma Quadrant.

Assimilation
The Borg Collective assimilates any species and technology that they find useful. They are not interested in species with little biological or technological knowledge. Borg nanoprobes are injected into the victim's body through injection tubes coming out from the drone's upper hand. The Nanoprobes uses the victims bloodstream and red blood cells to reach their targets within the body to rewrite the victims DNA. Borg implants and an exoskeletton are created on the individual and the assimilated individual looses the hair and grows dark veins all over their exposed skin. A cortical Implant is installed in the cerebral cortex to allow the assimilated humanoid to be included in the collective consciousness. Other Borg implants that are installed, among others, are the regenerative force field generator, a subspace transponder and a neural link generator. Finally the drone will be given a specified task to carry out within a specified unimatrix. The assimilated individual has now lost all sense of identity and is under total control of the hive mind.

Asteroids
Irregularly shaped rocks in space that can be sized between a few feet and several miles wide. Most asteroids in earth's solar system are part of a belt between Mars and Jupiter.

Asteroid Belt
An area with many asteroids which often orbits a planetary system.

A tornado-like phenomenon which form at the interfold between space and subspace. The phenomenon sends out massive discharges of plasmatic energy. Tom Paris piloted a shuttle through astral eddies in episode Real Life.

Badlands
Naturally occurring area in the Alpha Quadrant near the Cardassian border which is considered very dangerous for space travel because of the areas many Plasma storms. Sensors and warp drive might not work properly in this part of space.

Barge of the Dead, The
The vessel transporting dishonored klingons to Grethor.

Bat'leth
A two metre long Klingon weapon with two handholds on the outside edge. The first bat'leth was, according to Klingon legend, created by Kahless when dropping a strand of his hair in a vulcano and later into the lake Lursor. He then formed it into a bathleth which he used to kill Molor, a Klingon tyrant. A typical bat'leth is 116 centimeters long and is composed of baakonite metal. The bat'leth is carried along the inside of the arm.

Borg Cortical Node
The primary cortical node is installed through a circular interface in a port above the drone's right eye. It regulates all Borg cybernetic implants and is the most important part of the Borg drone. The cortical node also allows drones to interface with an alcove and regenerate. There is no back-up system and a faulty cortical node will result in death for the drone If not replaced in time. The cortical node suppresses the humanoid immune system and prevents drones from rejecting Borg implants. If the cortical node is left inactive it quickly becomes useless.

Borg Drone
A humanoid assimilated by the Borg Collective. The assimilated individual loses all sense of identity and is under total control of the hive mind. Borg drones are always shown in an upright position, even during the regeneration cycle, and walk in a robot like fashion due to limitations of its exoscelleton. They possess a superior physical strength and are almost invulnerable due to their ability to adapt to enemy weapons and to regenerate their borg drone shielding.

Borg Exoskeleton
The outer armour covering the skin of Borg Drones. The armour is attached directly to the skin on all parts of the body, except for the face and parts of the head, and protects the drone from being damaged.

Borg Implants
Cybernetic devices like limbs, eyes, organs, cortical nodes and neural processors (see below) inside and outside the body of a Borg drone.

Borg Neural Processor
All drones are equipped with a neural processor that sends out a neuro-electric field that is capable of regenerating damaged componants on other borg drones. It can heal both organic and inorganic bodyparts. The drone dies if the implant is removed.

Borg Regeneration
Each Borg drone is assigned an alcove in which the drone regenerates (refuels) its Borg system such as implants. Regeneration is the Borg equivalent to sleep and to achieve full power the drone must complete the full regeneration cycle.

Borg Queen
The Borg Queen has maintained her individuality in a way that normal Borg drones can't. She spends most of her time in unimatrix 1 with her head and spinal column in her alcove. She seems to have a mostly synthetic body filled with cybernetic implants below her head and shoulders.

Bussard Collectors
Bussard collectors are located at the front of the nacelles and carry the name of the 20th century Terran scientist who came up with the basic principles behind these collectors. They are used to collect particles, such as hydrogen atoms, that can be used as fuel.

Cortical Stimulator
Standard medical equipment on Federation starships that stimulate neural activity in humanoids. The device is placed on the neck below the humanoid's ear. It is often used when a person's bio-neural energy is low.

Dark Matter
Dark matter is composed of particles that can't be seen because it doesn't absorb, reflect, or emit light.

Dark Matter Nebula
A nebula that emit strong electromagnetic (EM) emissions. Trianic-based energy beings live in some dark-matter nebulas. They absorb the neural energy of passing ship crews.

Day of Honor Ritual
A yearly ritual where Klingon warriors have to endure physical and mental challenges to assess his or her honor. The warrior prepares by eating from the heart of a sanctified Targ and drink mot'loch from the grail of Kahless. Many Klingons traditionally eat Blood Pie on the Day of Honor. During the ritual the warrior is questioned about his or her honor during the passed year. If the warrior is unworthy he or she can go through the Ritual of 20 Painstiks or battle a bat'leth master. Torres and Paris designed a holoprogram to test her honor which involved the ritual of twenty painstiks and travelling over the sulphur lagoons of Gorath.

D-Class Planet (Asteroid/Moon)
Barren and cratered planets with no or very tenuous atmosphere, which orbits larger planets or exists in asteroid fields. Our moon is a D-class planet.

The Delta Quadrant is located in the upper right corner of the Milky Way Galaxy using the Federation method of Stellar Cartography. Species like Kazon sects, the Vidiian, Talaxian, Ocampa, Hirogen, Malon, Borg and Species 8472 were encountered in this quadrant.

Deflector Shields
Energy shield that can be generated around a starship or structure for protection against enemy weaponry or natural hazards. These forcefields loose energy when hit by weaponry and can be rendered useless if the enemy firepower is great enough. Energy can be rerouted from other systems to strengthen the deflector shield.

EM Emission
Short for Electromagnetic emission. EM is a commonly used term within the federation.

EMH Mark I
Also known as Emergency Medical Hologram, which is a program designed by Dr Zimmerman. The EMH is a substitute holographic physician to use as an emergency option if a starship's doctor is incapacitated. The EMH is programmed with over five million possible treatments and with information from 2,000 different medical references as well as the experience of 47 physicians. He also contains more than fifty million giga quads of computer data and is equipped with the medical knowledge of more than three thousand cultures. The EMH can only function in areas equipped with holo emitters. The EMH on USS Voyager was automatically activated when the original doctor died during the transport to the Delta quadrant. The EMH was a prisoner within the walls of sickbay until he received the mobile emitter in episode future's end. Torres is in charge of maintaining the EMH.

Emission Nebula
A type of nebula, which renders cloaking devices useless. It is created when ultraviolet light from a hot star shines on a cloud of hydrogen gas. It shines when electrons recombine with protons to form hydrogen atoms.
