Nebulae in fiction

Nebulae, often being visually interesting astronomical objects, are frequently used as settings or backdrops for works of science fiction.

General uses of nebulae

Nebulae may be referred to in fictional works for their metaphorical (meta) or mythological (myth) associations, or else as daubs of light in the sky of Earth (sky), but not as locations in space or the centers of plot development:

 

There follow references to imaginary and real nebulae depicted as locations in space or the locations of planetary systems, categorized by genre.

Imaginary nebulae in fiction

Authors of science fiction have occasionally created imaginary nebulae in response to special plotting needs, although not nearly as often as they have chosen to pick from among the rich assortment of existing nebulae (next section).

Real nebulae in fiction

The following sections exhibit a collection of real nebulae that contain imaginary stars or planetary systems, or that otherwise serve as settings for works of science fiction:

Andromeda Nebula/Great Nebula in Andromeda

The Andromeda Galaxy, formerly known as the Andromeda Nebula.

Spiral nebula cataloged as M31. Although this object is now known to be a galaxy, some authors aim for an archaic flavor by referring to it using its historical designation as a nebula (see graphic). For works of fiction which feature Andromeda as a galaxy, see Galaxies in fiction.

  • The great nebula in Andromeda passed under them, a whirling pancake of cold fire. ("Dead Ahead" as "Ultimate Quest," 1950)
  • I am conducting a statistical count of the Cepheid variables in the Great Nebula of Andromeda. ("The Absent Minded Professor" as "First Star I See Tonight," 1954)
  • No problem there; I'll take you to the Great Nebula if you like. (Space Opera, 1965)
  • ...thence by [the] Andromeda Line ... in the direction of the Great Nebula ... ("Milton Hack from Zodiac" as "The Man from Zodiac," 1967)
  • ...a spiral nebula, the Great Nebula in Andromeda, spinning, reeling, flashing, glimmering, alone and tremendous in the darkness of space. (The View from Chickweed's Window, 1979)
  • ...send them off to the Great Spiral Nebula. (Araminta Station, 1987)
  • I mentioned Emperor Schulz, who owned the Great Nebula in Andromeda. (Throy, 1992)

Crab Nebula

The Crab Nebula, residue of supernova SN 1054.

Supernova remnant cataloged as M1. The Crab Nebula is the residue of supernova SN 1054, which also left a neutron star, the Crab Pulsar, at its center (see graphic). The nebula's spattered, explosive appearance has stimulated several authors to imagine the purposeful destruction of its progenitor star by one or another race of aliens.

Uxarieus

Eagle Nebula

The Eagle Nebula, location of the Pillars of Creation, visible as a central knot of detail in the bright breast area of the eagle, beneath its bowed head.

Diffuse emission nebula, or H II region, cataloged as M16. The Eagle Nebula, so named from its supposed resemblance to the iconic raptor (frontal view, wings spread, head bowed), is the location of one of the Hubble Space Telescope's most popular images, the Pillars of Creation (see graphic below), which often appear in science fiction film and television. The picture was released by NASA in 1995; within two years (1997) it had already found use in a number of works.

Horsehead Nebula

Dark nebula cataloged as B33 in emission nebula IC 434, located close to the belt-star Alnitak in the constellation Orion (see graphic). The Horsehead Nebula is part of the much larger Orion Molecular Cloud Complex. Many of the works of fiction below use the nebula as a cloud of more or less impenetrable darkness; others imagine a host of stars and planets before, within, and especially behind the nebula.[note 5]

The Ood Sphere, homeworld of the Ood in Doctor Who episode "Planet of the Ood." The planet is located in the Horsehead Nebula.
*Noveria, the secret ice world where the Noveria Development Corporation pursues advanced, controversial research, has attracted the attention of the geth artificial intelligences, and the council needs to know why—a job for protagonist Commander Shepard and the Normandy (Mass Effect).
The headquarters of the human supremacist organization Cerberus has been discovered on Cronos, and Shepard is sent in to bring out an AI who will play a key role in the final battle against the Reapers (Mass Effect 3).

Hourglass Nebula

The Hourglass Nebula, artificially colorized image from NASA's Hubble Space Telescope.

Planetary nebula cataloged as MyCn 18 discovered by Mayall and Cannon in the early 20th century, but only resolved as an hourglass shape by the Hubble Space Telescope in 1996 (see image).[28] It is conjectured that the hourglass shape is produced by the expansion of a fast stellar wind within a slowly expanding cloud which is denser near its equator than its poles. The formation of the shape of the inner "eye" is not yet fully understood. Because of the recent resolution of the nebula's detailed appearance, it has only appeared in fictional works since 1996.

*Purgatory is a maximum security prison starship in orbit around the star Osun owned and run by the Blue Suns security organization. It is where Commander Shepard can undertake a Mission to recruit Jack—master criminal, potential romantic interest, and possibly one of the most powerful human biotics alive, considered so dangerous that she is kept in cryogenic stasis aboard the isolated prison vessel. (Mass Effect 2 ).
Hagalaz is a second-tier garden world that receives little attention from the galactic community. It is however the secret lair of the Shadow Broker, the enigmatic anonymous trafficker in classified information, and the location of the final showdown between Shepard's friend Liara T'Soni and the secretive master spy. (Mass Effect 2: Lair of the Shadow Broker ).

Lagoon Nebula

The Lagoon Nebula in Sagittarius.

Diffuse emission nebula, or H II region, cataloged as M8. The Lagoon Nebula is one of only two star-forming nebulae faintly visible to the naked eye from mid-northern latitudes. Seen with binoculars, it appears as a distinct oval cloudlike patch with a definite core. A fragile star cluster appears superimposed on it. The Lagoon Nebula contains at its center a structure known as the Hourglass Nebula (so named by John Herschel), which should not be confused with the better known Hourglass Nebula (see above).

Messier 78

Reflection nebula in the constellation Orion, cataloged as M78 (see graphic). M78 is the brightest of a group of diffuse reflection nebulae that belong to the Orion Molecular Cloud Complex and is about 1,600 light years distant from the Earth. M78 is easily found in small telescopes as a hazy patch and involves two stars of 10th magnitude. These two stars, HD 38563A and HD 38563B, are responsible for making the cloud of dust in M78 visible by reflecting their light. About 45 variable stars of the T Tauri type,[note 9] young stars still in the process of formation, as well as some 17 Herbig–Haro objects are known in this nebula.

NGC 2440

Planetary nebula cataloged as NGC 2440. Its central star, HD62166, is possibly the hottest known white dwarf. The nebula, situated in the Puppis constellation, was discovered in 1790 by William Herschel, who described it as "a beautiful planetary nebula of a considerable degree of brightness, not very well defined." The nebula is located about 4,000 light years from the Sun, a large distance compared to the stars appearing in science fiction (Deneb is the farthest, at 1550 light-years), but closer than most of the other nebulae in this list. This relative proximity, as well as its spectacular appearance and its location in a rich star field, may promise more fictional uses in the future.

Omega Nebula

Diffuse emission nebula, or H II region, in the constellation Sagittarius cataloged as M17, and named the Omega Nebula in 1833 by John Herschel because in his limited-resolution view its shape resembled the Greek letter Ω. Located between five and six thousand light-years from the Earth, It is considered one of the brightest and most massive star-forming regions of our galaxy, containing a collection of over 1000 stars[31]—although it is one of the youngest clusters known, with an age of just 1 million years. Its local geometry is similar to the Orion Nebula except that it is viewed edge-on from the Earth rather than face-on.[32]

*Built in the mined-out husk of a metallic asteroid, the Omega space station has been a haven for criminals, terrorists, and malcontents for thousands of years. The space station's original elegant design has given way to haphazard expansion by scrabbling factions of every species. It is the location of the missions Archangel, The Professor, The Veteran, Aria T'Loak, and The Ardat-Yakshi (all in Mass Effect 2 ).

Orion Nebula

Diffuse emission nebula, or H II region, cataloged as M42, and situated south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. Located about 1300 light-years away, it is the closest region of massive star formation to the Earth. The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features.

Trifid Nebula

Nebula of mixed types, catalogued as M20 and located in Sagittarius. Its name means "divided into three lobes." The body is an unusual combination of an open cluster of stars (a good setting for fiction), an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent gaps or spokes within the emission nebula that cause its three-part appearance). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.

Veil Nebula

A star like Festi in the Witch's Broom region of the Veil Nebula.

Supernova remnant, cataloged as NGC 6960 (and a variety of other designations). The Veil Nebula is one component of the large but relatively faint spherical residue of a supernova that exploded some 5 to 8 thousand years ago. Discovered in 1784 by William Herschel, the remnant appears to human observers as a braid of thread-like strands. The standard interpretation is that the shock waves defining its surface are so attenuated that the shell is visible only when viewed edge-on, giving it the appearance of a collection of filaments.

Witch Head Nebula

The Witch Head Nebula, produced by the NASA Digitized Sky Survey.

The Witch Head Nebula, produced by the NASA Digitized Sky Survey.

Faint reflection nebula in the Eridanus constellation near Orion, possibly an ancient supernova remnant, cataloged as IC 2118. Because the gas cloud is illuminated by nearby blue-white supergiant star Rigel in Orion (see graphic; Rigel is off-image to the right), and due to its preferential scattering of short-wavelength light, it appears a vivid blue in telescopic images. Radio observations show the presence of molecular clouds and star formation; candidates for pre-main sequence stars and some classic T-Tauri stars[note 9] have been found deep within the nebula.[41]

Notes and references

Notes

  1. In a somewhat complicated joke, the title of the book is derived as follows: Bears (36 years) live about three times as long as cats (12 years). Cats have nine lives. Therefore bears have 27 lives. The novel covers the first half of Bluebear's life. Half of 27 is 13 12.
  2. Colossus (1966), the first novel in the Colossus trilogy, was filmed as Colossus: The Forbin Project in 1970.
  3. In the novel Nova, Earth and the Pleiades Federation vie for influence in the Outer Colonies where mines produce trace amounts of the prized power source Illyrion, the superheavy material (comprising elements 305 and above) essential to starship travel and terraforming planets. Lorq Von Ray, a scarred and obsessed captain from the Pleiades, recruits a disparate crew of misfits to help him achieve political and economic dominance by securing a vastly greater amount of Illyrion—seven ton's worth—directly from the heart of a stellar nova.[14]
  4. In Dante's Inferno, Antaeus, a murderous half-giant who drew his strength from contact with the earth, appears in Canto XXXI (later illustrated by Gustave Doré); Cacus, a pre-Roman anthropophage slain by Hercules, appears in Canto XXV; Dis, the location of the lower circles of Hell, appears in Cantos VII, XI, and XII; Farinata, a Florentine Ghibelline factional leader, appears in Cantos VI and X; and Plutus, the Greek god of wealth, appears across Cantos VI and VII (later illustrated by Gustave Doré).[15]
  5. A visual inspection of photographs of the Horsehead Nebula shows that, in a view from Earth, there are few stars in front of the nebula. Authors are free to imagine a trove of stars behind it.
  6. Asimov makes it clear that, from within, the dark Horsehead Nebula is a vanishingly thin mist, barely detectable save by its blockage of distant starlight. Compare this with Berserker Blue Death by Fred Saberhagen, above, where the pale billows of the Milkpail Nebula assume a sculpturally solid speleomorphic consistency.
  7. In his fable of the Horace Hedd folk etymology illuminating the limitations of geocentrism, Asimov outsmarted himself. From his earlier Galactic Empire novel Pebble in the Sky it is clear that the English language is no longer spoken either on Earth or in the larger galaxy: ... the woman [a resident of Earth's far future] spoke in no language Schwartz [a 20th-century Chicago man thrown forward through time] had ever heard.[20] The Horsehead/Horace Hedd pun only works in an anglophone galaxy. In his critique of geocentrism, the author neglected his own unconscious anglocentrism.
  8. Compare the superheavy element 161 in Ancient Shores to talhassium (element 170) in the novel Psion by Joan D. Vinge and Illyrion (an amalgam of trans-300 elements) in Nova by Samuel R. Delany.
  9. 1 2 T Tauri stars are immature pre-main sequence stars, powered by gravitational contraction rather than nuclear fusion. Many of them are surrounded by protoplanetary discs which will only later evolve into planets.[30] As such they are not good candidates for the hosts of habitable worlds in fiction.
  10. In his galactic cosmography, Aldiss locates the Earth in a region of the Milky Way called The Rift,[38] while he places the Veil Nebula—which lies in actuality less than 1500 light-years from the Sun—in the "remote" Sector Vermilion of the galaxy.
