Nebula


 * You may be looking for the, a class of Starfleet starship.

A nebula is an interstellar cloud of matter, comprised usually (and mostly) of dust, hydrogen gases (or, in rarer cases, other types of gases) and plasma. A nebula is the first stage of star development.

Starfleet starships used nebulae to their strategic advantage in conflicts with hostile starships, since sensors and other critical shipwide systems could be affected by, or perform poorly in, some nebulae.

The Ularen disturbance is a nebula filled with unusual subspace ripples preventing warp travel. The USS became the first Starfleet vessel to successfully chart the outward region of the disturbance. (Star Trek: Pioneer)

In 2285, Captain James T. Kirk took a damaged USS into the Mutara Nebula to buy more time against Khan Noonien Singh and his crew aboard the hijacked USS. The Enterprise and Reliant battled in the Battle of the Mutara Nebula, with Khan and the Reliant losing. Khan detonated the Genesis Device, consolidating the Mutara Nebula to create a new system; the Enterprise escaped thanks to Captain Spock's sacrifice. 

USS Captain Hikaru Sulu masked his ship's approach to Qo'noS by taking it through the Azure Nebula in 2293. in the nebula, they encountered a Klingon bird-of-prey, commanded by Captain Kang. Sulu ordered the volatile sirillium gas be ignited in an attempt to evade the Klingons. It succeeded, but Sulu never entered the event in the ship's log. 

In 2366, the USS hid in the Paulson Nebula as a tactic to delay the Borg cube from proceeding to Earth. The Borg responded with magnetometric-guided charges to force the Enterprise out of hiding. 

Captain Ransom and his crew hid for three days in a nebula near Epsilon IV to avoid a Klingon bird-of-prey. 

On USS's first year in the Delta Quadrant, Captain Kathryn Janeway and her crew discovered an organic life form that appeared as a nebula. 

Early on in the Dominion War, due to the close proximity of the Second Fleet's staging grounds to a nebula the Dominion was able flank the fleet by using the nebula to hide their ship movements.

Voyager also encountered a nebula rich in protomatter in 2374. 

The USS's crew revealed a hundred Jem'Hadar ships hidden in the Ludine Nebula, waiting to attack the Fifth Fleet during the Dominion War in mid-2375. (: "Danger Zone")

In 2377, the Delta Flyer II surveyed a nebula near Annari space for dilithium. 

Later in the same year, Voyager ' s Doctor, as the ECH, piloted the abandoned ship into a nebula, escaping the Quarren marauders. 

Also in that same year, the USS investigated a distress signal emanating from the Marauder nebula. Upon closer investigation, they discovered the USS Excelsior stuck in the nebula, and both ships were pulled into a temporal anomaly, sending them back to the 20th century mirror universe Earth. (Star Trek: Dragon: "Dimensional Exploration-Ghost Ship")

In 2378, Voyager discovered a Borg transwarp hub located in a nebula.
