Black hole

A black hole is an incredibly dense remnant of a star that has collapsed into a singularity under its own gravity upon running out of fuel for nuclear fusion. Black holes have extremely strong gravitational fields, similar to cosmic string fragments, so powerful that not even light can escape. They were often surrounded by an accretion disk.

The late-20th century NASA probe Voyager 6 disappeared into a spatial anomaly that at the time was believed to be a black hole, emerging on the other side of the galaxy, where it came into the possession of a race of sentient machines. ()
As of 2152, Vulcans had charted over two thousand black holes. 
In 2152, encountered a black hole that was part of a trinary star system, something unheard of by either Starfleet or Vulcan scientists. Attempting to study the black hole, the Enterprise crew became affected by an exotic form of radiation which caused nearly all members of the crew to exhibit irrational and obsessive behavior. Sub-Commander T'Pol, whose Vulcan physiology was immune to the radiation, performed an analysis which indicated that prolonged exposure to the radiation would be fatal to the crew, forcing her and Captain Archer to navigate Enterprise through a hazardous debris field in order to escape the influence of the radiation in time.

In 2257, the Talosians created an illusory black hole around their homeworld, Talos IV, to test the resolve of Michael Burnham and Spock as they approached the planet. Spock piloted their shuttle directly into the event horizon, breaking the illusion and revealing Talos behind it. ()
The primary of the Finibus system was a black hole, which had six planets (including a class M world, Finibus III) and a brown dwarf companion. In 2259, the black hole consumed the brown dwarf; during the event, the crew of the used its powerful gravity to slingshot the ship to safety from a Gorn destroyer, while simultaneously detonating a malfunctioning AP 350 device in the accretion disk to make it appear as though the Enterprise had been destroyed. ()
In the alternate reality, Takayama-type shuttlecraft were equipped with sensors that could analyze black holes. ()
In 2366, the engaged in an operation to stabilize the moon of Bre'el IV, which was in danger of crashing into the planet. The crew was informed by Q that the deterioration of the moon's orbit was most likely caused by a black hole passing through the star system's plane at near-right angles. ()
In 2369, the crew of the Enterprise-D encountered a race of aliens from another time continuum who utilized the gravity wells of black holes as nests for their young. The aliens had mistaken a Romulan vessel's artificial quantum singularity, which the Romulans used as a power source, for a natural black hole, and their young became trapped. When the Enterprise generated a power transfer beam to send energy to the Romulan ship, it resulted in the creation of a temporal aperture, which disrupted spacetime around the ships and created a series of temporal fragments. With the help of the Enterprise crew, the embryonic lifeforms were eventually freed. ()
In 2371, the encountered and became trapped within the event horizon of a type 4 quantum singularity in the Delta Quadrant. Due to massive temporal distortions being emitted from the singularity, the crew of Voyager encountered time-delayed reflections of their own ship, initially making them believe that they had encountered another vessel being pulled into the singularity. Eventually, they were able to find their way out by exiting through a breach in the event horizon which they had created when they initially entered. ()
In 2374, Voyager discovered a communications relay network which was a hundred thousand years old and was being used by the Hirogen in the Delta Quadrant. Analysis indicated that each of the relay stations utilized a harvested microsingularity as a power source. While engaged in battle with a Hirogen vessel, the Voyager crew used an antithoron burst to destabilize the containment field around the singularity and increase its gravitational pull. The plan worked, but the containment field failed, destroying the relay station and causing the singularity to grow into a black hole. While Voyager was able to escape, the Hirogen ship was destroyed. ()
At some point circa 2380, the nearly fell into a black hole in a binary star system after sustaining damage from a meteor impact but managed to escape. ()
In 2381, the Cerritos was ordered to fly to a black hole that was feeding on a temporal rift by her captain, Carol Freeman. This was done as part of a plan to force Shari yn Yem, a Starfleet drill instructor, to change their scores after learning she targeted them to justify her continued employment in Starfleet. Due to her inexperience and not realizing they could escape with ease, Shari panics and agrees to change the scores. ()
Black holes can be artificially created through the ignition of a small amount of red matter. In 2387, Ambassador Spock created such a black hole in order to absorb the energy of a supernova, formerly the Romulan sun, which threatened the entire galaxy. Spock's plan succeeded, but he was too late to save Romulus, which was destroyed by the exploding star. The resulting black hole created a tunnel through spacetime, into which both Spock's ship, the , and the Romulan mining vessel Narada were pulled, depositing the Narada in the year 2233, resulting in the creation of the alternate reality. 
Spock, who entered the black hole a few seconds after the Narada, emerged twenty-five years later due to the time differential, and was captured by Nero, the Naradas captain. Nero, who held the Federation responsible for the destruction of his homeworld, stole the red matter from Spock's ship and used it to create a black hole at the center of , destroying the planet. Nero attempted to perform the same action on Earth as he did to Vulcan but was stopped when piloted the ship containing the red matter to a collision with the Narada. This caused the red matter to ignite and create a black hole within the Narada itself, destroying the ship. (; )
In 2401, black hole was listed twice in a list of results for Raffaela Musiker's search for the "red lady". ()
In 3191, it was discovered that the structure containing a portal to the Progenitors' technology was at the lagrange point between a binary system of two primordial black holes. The two black holes were stated to be older than anything else in the galaxy. The portal drew power from one of the black holes after Moll inadvertently activated a safety feature. After deciding to ensure that no one could ever use the technology again, Captain Michael Burnham had the cast the portal beyond the event horizon of one of the black holes. ()

This type of anomaly was referred to in the scripted description of a scene from wherein General 's Bird-of-Prey is located by the using a photon torpedo, disrupting the Klingon Bird-of-Prey's cloaking device and making the ship visible. The film's script lightheartedly referred to the point at which the craft became trapped as "the 'black hole'".
The Talosian illusory black hole marked the first time that the then latest, most recent, scientific visual interpretation of the phenomenon is seen in Star Trek. The visual interpretation is based on the work of theoretical physicist and Nobel Prize laureate and his collegues. Thorne closely cooperated with the digital modelers of CGI company Double Negative (DNeg) to create a scientifically accurate representation of a black hole, which was for the first time featured in the acclaimed 2014 science fiction film . DNeg incidentally, went on to (co-)provide the digital visual effects for , , and . It is also known that DNeg has contributed CGI to the second season of Discovery, albeit uncredited, and it is tempting to assume that it was their Interstellar black hole model that stood in for the Talosian black hole, though firm confirmation of this has yet to be forthcoming.
