Penal colony

Penal colonies were remote prison facilities with characteristics that vary in accordance with the needs and philosophies of their governing cultures. Typically, a sentence to a penal colony differs from normal incarceration by charging the inmate to perform a service or labor, or to help facilitate their own rehabilitation.

During his first visit on Deep Space 9 Q referred to the station as "dreary little gulag" and commented that Benjamin Sisko was penalized there. 

Federation penal colonies
In the mid-23rd century, the penal systems of the United Federation of Planets shifted focus from incarceration and punishment to humane rehabilitation, made possible by new technologies and drug therapies. A key figure of this transition was Doctor Tristan Adams. From the late 2240s and into the 2260s, his practices were replicated in many Federation penal colonies, turning what were essentially cages into effective hospitals. Until promising therapies were developed, those few criminally-insane beings deemed incurable and incorrigible were kept in the secure isolation of Asylum facilities. 

Ambassador Robert Fox threatened to have Montgomery Scott sent to a penal colony for disobeying his direct orders while Captain James T. Kirk was held captive on Eminiar VII.

Keto-Enol penal colonies
In the 22nd century, the Enolian government operated at least two penal colonies:
 * Canamar, a notorious high security facility
 * Duronom, a facility for minor offenses

Mab-Bu VI-A
During the mid-19th century, a penal colony was established on the moon orbiting Mab-Bu VI that included hundreds of prisoners from the Ux-Mal system. As punishment, the prisoners were separated from their bodies and left to drift in the moon's electromagnetic storms. 

Rura Penthe
Established sometime prior to the mid-22nd century, the Klingon gulag of Rura Penthe was a prison with no stockade, guard tower or electrified frontier. Its only form of protection was a magnetic shield surrounding the inhabited dilithium mines to prevent unauthorized beamouts.

The stipulations for the inmates of the prison included the simple fact that no one can escape from below. If prisoners worked well, they would be treated well; if they worked badly, they would be exiled to the asteroid's frozen surface, where nothing could survive for very long.

In late 2152, Jonathan Archer was captured by the Klingons after assisting Rha'daran rebels. Put on trial on Narendra III, he was sentenced to labor on Rura Penthe, but managed to escape. 

In 2293 James T. Kirk and Leonard McCoy were sentenced to Rura Penthe to spend the rest their natural lives mining dilithium, but also escaped. 

Lunar V
The Angosian Lunar V colony was created for its genetically-enhanced soldiers who previously participated in the Tarsian War. According to the Angosian government, the soldiers were placed there "for their own protection as well as that of others." Despite the fact that they made every effort to make the colony as amiable for its "colonists" as possible, the fact remained that it was still a prison. 

Ennis/Nol-Ennis penal moon
Located in the Gamma Quadrant, this moon served as a place of banishment for the Ennis and Nol-Ennis factions after mediators on their shared homeworld were unable to resolve their conflict. The moon had an automated orbital defense system and its atmosphere contained artificial microbes which would regenerate the dead. Because permanent death was impossible, the Ennis and Nol-Ennis were condemned to fight each other for eternity. In 2369, the Starfleet runabout USS Yangtzee Kiang crash-landed on the moon, killing one of the passengers, Bajoran Kai Opaka. As she, too, was regenerated, Kai Opaka decided to remain on the moon to attempt to mediate between the Ennis and Nol-Ennis.
