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


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.
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

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. For works of fiction which feature Andromeda as a galaxy, see Galaxies in fiction.
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. 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.
Diffuse emission nebula, or H II region, cataloged as M16. The Eagle Nebula, so named from its supposed resemblance to the iconic raptor, is the location of one of the Hubble Space Telescope's most popular images, the Pillars of Creation, which often appear in science fiction film and television. The picture was released by NASA in 1995; within two years it had already found use in a number of works.
Catalogued as IC 1805, the Heart Nebula is an emission nebula located in the Milky Way's Perseus Arm approximately 7500 light-years from Earth in the constellation Cassiopeia.
Dark nebula cataloged as B33 in emission nebula IC 434, located close to the belt-star Alnitak in the constellation Orion. 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.
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. 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.
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, which should not be confused with the better known Hourglass Nebula.
Reflection nebula in the constellation Orion, cataloged as M78. 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, young stars still in the process of formation, as well as some 17 Herbig–Haro objects are known in this nebula.
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, has a spectacular appearance and is located in a rich star field.
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—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.
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.
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, an emission nebula, a reflection nebula and a dark nebula. Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.
Supernova remnant, cataloged as NGC 6960. 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.
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, 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 have been found deep within the nebula.
