 | Alwanir Nebula |  |
|---|
|
|---|
Celestial body studied by the Enterprise-D in 2370. The Gariman system is in the region.

 | Azure Nebula |  |
|---|
|
|---|
A notable Class 11 nebula with trace amounts of sirillium along the Federation-Klingon border, where Sulu intended to hide his approach to Qo'nos during the Khitomer crisis of 2293. Kang's battlecruiser decloaked and found them anyway.
(ST6: The Undiscovered Country) |

 | Betreka Nebula |  |
|---|
|
|---|
An incident in or near this nebula between the Klingons and Cardassians led to hostilities between the two empires for 18 years.

 | Chamra Vortex |  |
|---|
|
|---|
An uncharted nebula in the Rakhari sector of the Gamma Quadrant. There are millions of asteroids in the Chamra Vortex. The ionized gases screen ships from sensors. The vortex is riddled with volatile pockets of a gas the Rakhari call toh-maire. If they are destabilized, they can ignite, and blow a shuttle apart. The Chamra Vortex lies between the Gamma Quadrant terminus of the Bajoran wormhole and the planet Rakhar. (DS9: Vortex)

 | Class 17 nebula |  |
|---|
|
|---|
A blue nebula in the same sector as Porakas, source of a viral parasite that sent Tuvok's memory back to the U.S.S. Excelsior. With standard hydrogen and helium amounts, it scanned 7,000 ppm of sirillium and had high plasmatic turbulence.
(VOY: Flashback) |
| |
 | Dark matter nebula |  |
|---|
|
|---|
An otherwise unnamed Delta Quadrant nebula, home of the Komar energy beings who feed off the neural energy of unwitting and unfortunate passers-by. Neelix once lost a warp nacelle due to bow wave pressure while piloting a ship through a dark matter nebula. Its strong EM emissions make it an ideal hiding spot.
(VOY: Cathexis)

| |
 | Emission nebula |  |
|---|
|
|---|
Interstellar dust cloud that emits electromagnetic radiation and renders cloaking devices useless. One such nebula is in Cardassian space in the Korma/Rakal/Loval area, where the Amleth system and its one Class-M planet are located.

 | FGC-47 |  |
|---|
|
|---|
A rare phenomenon, a nebula formed around a neutron star, that the U.S.S. Enterprise NCC-1701-D is to study circa stardate 45852.1; it is vividly red and includes higher than usual levels of hydrogen, helium and trionium. It also contains an intelligent energy-vortex life form capable of metamorphosis and the first recorded instance of energy strands that create a drag against the ship's shields and prevent creation of a warp field.
(TNG: Imaginary Friend) |
| |
 | Gamma Erandi Nebula |  |
|---|
|
|---|
A nebula of young stars near Betazed -- at least 15 hours' travel at unspecified warp -- that had been unmapped by the Federation until 2366. Its emissions interfere with subspace communication, a normal occurrence for such a phenomenon.
(TNG: Ménage à Troi) |

 | Hugoro Nebula |  |
|---|
|
|---|
Site where an U.S.S. Enterprise NCC-1701-D ambush of Maquis is spoiled when Ro defects to them.
(TNG: Preemptive Strike) |
| |
 | Inversion nebula |  |
|---|
|
|---|
Theorized but never before seen in the Alpha nor Delta quadrants, UFP astrotheorists had presumed the hypothetical nebula's explosive plasma strands would burn out after a few years, but Marayna's nebula discovered in the Delta Quadrant is centuries old.
(VOY: Alter Ego) |
| |
 | Jenkata Nebula |  |
|---|
|
|---|
A Gamma Quadrant nebula near the Teplan system where Kira hides for a week from Jem'Hadar patrols while Bashir and Dax try to cure the Teplan sufferers' Blight.
(DS9: The Quickening) |
| |
 | Lantar Nebula |  |
|---|
|
|---|
A nebula (pronounced "lun-TARR") which includes the star Hoek.
The Sampolo relic is of interest on its fourth planet -- one of the sights Q tries to tempt Vash with in rejoining him.

 | MacPherson Nebula |  |
|---|
|
|---|
A source of artificial vertion particles used to save the emergent holodeck lifeform.
(TNG: Emergence) |
| |
 | Mar Oscura Nebula |  |
|---|
|
|---|
A nebula, unexplored prior to circa stardate 44932, that contains pockets of "dark matter" spatial deformations as well as several Class M planets.
(TNG: In Theory) |
| |
 | McAllister C-5 Nebula |  |
|---|
|
|---|
Located just 7 light-years from the United Federation of Planets inside Cardassian space, near Minos Korva, and the deducted origin of the Cardassian ship Reklar due to signs of a molecular dispersion field on its hull acquired there.
(TNG: Chain of Command, Part II) |
| |
 | Mutara Nebula |  |
|---|
|
|---|
The Mutara Nebula is an intersellar dust cloud in the Mutara Sector, where Khan detonated the experimental Genesis torpedo in 2285, causing the Mutara Nebula to re-form into a habitable planet. The nebula was composed of ionized gas that made a starship's sensor highly unreliable when inside.
(ST2: The Wrath of Khan) |

 | Omarion Nebula |  |
|---|
|
|---|
A Gamma Quadrant area that was home to the original Founders Homeworld.
(DS9: The Search, Part I) |
| |
 | Paulson Nebula |  |
|---|
|
|---|
A nebula in the area of Zeta Alpha and Sentinel Minor, which registers 82 percent dilithium hydroxyls, with magnesium and chromium as well. The U.S.S. Enterprise NCC-1701-D takes refuge there in 2370 within its sensor-confusing material from the renegade Borg.
(TNG: The Best of Both Worlds, Part I) |

 | Rolor Nebula |  |
|---|
|
|---|
A nebula lying between Bajor and the Dreon system which most ships on the route go around, including Yates' Xhosa.

"Stellar nursery" studied by the U.S.S. Enterprise NCC-1701-D when Professor Galen asks Captain Picard to join him.
