The planetary systems of stars other than the Sun and the Solar System are a staple element in much science fiction. Vega (Alpha Lyrae) is a blue-white star in the constellation Lyra (the lyre, see High Sierra, below) that is frequently featured in works of science fiction. Like its bright cousins Sirius, Deneb, and Altair, it is classified as a star of spectral type A. Roughly two and a half times the size of the Sun, it is 40 times as luminous and, together with Arcturus and Sirius, one of the most radiant stars in our galactic neighborhood. Its luminosity joins with its relative proximity to the Earth—it is only 25 light-years away—to make it the fifth brightest star in the night sky (see French and English Tragedy by George Croly, below). Vega is rendered decidedly oblate by its rapid rate of rotation[note 1], and since it is pole-on to the Sun, it appears significantly larger to earthbound observers than it actually is. For this and a variety of other reasons Vega has been extensively studied by astronomers, leading it to be termed "arguably the next most important star in the sky after the Sun."[3]

Based on an observed excess emission of infrared radiation, Vega appears to have a circumstellar disk of dust. This dust is likely to be the result of massive collisions between objects in an orbiting debris belt, and it is analogous to the Kuiper belt in the Solar System.[4] Irregularities in the disk also suggest the presence of at least one planet, about the size of Jupiter, in an orbit large enough to allow the formation of smaller rocky planets closer to the star.[5] Regardless of its ultimate tally of planetary companions, the fact that it has an estimated age of just 455 million years[2] suggests that the Vega system is too young to have fostered the development of life or a complex biosphere on any of its worlds.

The name Wega (later Vega) comes from a loose transliteration of the Arabic word wāqi‘ meaning "falling" or "landing," via the phrase an-nasr al-wāqi‘, "the falling eagle."[6] The star figures prominently in the mythology of cultures as diverse as the Polynesian, ancient Greek, Roman, Chinese (see Qi Xi below), Persian, and Hindu.


General uses of Vega

Vega may be referred to in fictional works for its metaphorical (meta) or mythological (myth) associations, or else as a bright point of light in the sky of the Earth, but not as a location in space or the center of a planetary system.
The Celestial Ford asterism crosses the Milky Way, and every year on the 7th night of 7th moon it hosts the magpie bridge between Altair and Vega.

Vega is a white main-sequence star in the constellation Lyra. At 25 light years away, it is the 5th brightest star in the Earth's sky, where it shines at an apparent visual magnitude of 0.03. Vega is the primary component of a multiple-star system. The iron abundance of Vega is -0.56 (27.5% of the Sun). It is moving through the Galaxy at a speed of 24.2 km/s relative to the Sun. Its projected Galactic orbit carries it between 23,900 and 25,400 light years from the center of the Galaxy. It will come closest to the Sun 264,000 years from now when it will brighten to magnitude -1.37 from a distance of 13.2 light years. Vega has no confirmed planets known to date (July 2013), but does have a circumstellar debris disk.
Sky position: RA 18h 36.9m, Dec +38° 46.8'
Common designations: Vega, Alpha Lyrae, 3 Lyrae, HIP 91262, HD 172167, HR 7001, Gliese 721

There follow references to Vega as a location in space or the center of a planetary system, categorized by genre:

Literature

    Foundation (1951), first novel in the Foundation series by Isaac Asimov. Vega was the capital of the Vega Province in the Galactic Empire, one of the wealthiest provinces in the entire Galaxy. Until the revolt of the Anacreon Prefect, it traded with Terminus, capital of the Foundation. Salvor Hardin, the first mayor of Terminus City, considered the threat of being cut off from Vega to be one of the gravest perils faced by the nascent Foundation. One of the commodities Vega exported was tobacco, of notably high quality.

The Stars My Destination protagonist Gulliver Foyle jauntes to the Vega system, encircled by swarms of blazing comets.

    Cities in Flight, (1955–1962), series of novels by James Blish. The Vega system is home to a civilization Blish names the Vegan Tyranny, which is blocking mankind's expansion into the galaxy. To fulfill their manifest destiny, men must defeat the Tyranny. The series' reflection of recent (from the vantage of 1955) earthly events, and the fascistic nature of the Vegan Tyranny, exhibit Blish's pessimistic view of the cyclic nature of history, as influenced by his reading of Spengler's The Decline of the West.[12] Blish later recycled these ideas in his novelization of "Tomorrow is Yesterday" (1967), an episode of Star Trek: The Original Series.

    The Stars My Destination (1956), classic science fiction novel (titled Tiger! Tiger! in the UK) written by Alfred Bester. After his apotheosis in the burning cathedral, the legendary Gully Foyle teleports stark naked to the vicinity of several stars, including Vega: "Vega in Lyra ... burning bluer than Rigel, planetless, but encircled by swarms of blazing comets whose gaseous trails scintillated across the blue-black firmament ..."[13] (see graphic) The interstellar "jaunting" sequence is typical of Bester's signature pyrotechnics, his quick successions of hard, bright images, and mingled images of decay and new life.[14]

    Have Space Suit—Will Travel (1958), juvenile novel by Robert A. Heinlein. "Vega V" (its real name is unpronounceable by humans[note 2][15]) is the home planet of an interstellar "nanny" civilization assigned to covertly mentor humanity when the Three Galaxies Federation becomes aware of our existence. Protagonist Kip Russell has rehabilitated an old space suit that comes in quite handy when he gets involved in an interplanetary kidnapping scheme. He and fellow victim Peewee Reisfeld are abducted first to the Moon, and then to Pluto, where he is seriously injured in their escape. Peewee's companion, the Vegan "Mother Thing," takes Kip to Vega V to be healed, and later to a tribunal in the Lesser Magellanic Cloud (see graphic) where he represents the human race.

    This Immortal (1966). novel by Roger Zelazny. In this post-apocalyptic novel, Arts Commissioner Conrad Nomikos—who may or may not be immortal, and who may or may not be a god—assumes the irksome task of escorting a Vegan grandee around the ruins of Earth, which is a popular tourist destination for those among the blue-skinned aliens with a hankering for primal thrills. The masterfully manipulative "immortal" isn't the only one with secrets, however; the Vegan harbors dark secrets of his own, and Earth-liberation rebels are trying to kill him. "Conrad Nomikos ... resembles Herakles—whose labors the plot of he novel covertly replicates—but is certainly both the Hero of a Thousand Faces and the Trickster who mocks the high road of myth..."[21]

    Contact (1985), novel written by Carl Sagan with unacknowledged assistance from Ann Druyan[22] (see also the film Contact below). SETI researchers detect a message from an extraterrestrial intelligence—a transmitter array (compare graphic) in orbit around the star Vega. As signal hunter Ellie Arroway breathlessly proclaims to a colleague over the telephone: "Yes, Vega is smack in the middle of the field of view. And we’re getting what looks like prime number pulses…"[23] After an arduous decoding process, Ellie and her colleagues discover and implement the plans for a wormhole transport device that carries five explorers to the center of the galaxy. There they speak at length with supernal sentiences, but can bring back no proof of the contact—so that when they return home nobody believes their experiences.

    Hyperion (1989) and The Fall of Hyperion (1990), the first two novels in the Hyperion Cantos written by Dan Simmons. Martin Silenus, the Poet of the Hyperion tales, survives tortured formative years growing up in the ambit of the marginally effective Rifkin Atmospheric Protectorate on Heaven’s Gate, "a minor world circling the star Vega ... [a] poisonous world [with, however] a farcaster connection to Sol System ..."[24] Too late for poor Martin, Heaven's gate is terraformed by the Hegemony of Man into an Edenic garden planet, and kept that way in the face of considerable difficulty thanks to its rich mineral resources—until the collapse of the farcaster network and the fall of the Hegemony. In the apocalypse, "...the worst has happened ... The Ousters are invading the Web. Heaven’s Gate is being destroyed ...".[25] The once beautiful world is reverted by TechnoCore cybrids posing as Ousters into a smoldering slag heap.

    Diaspora (1997), novel by Greg Egan. The Diaspora in the novel consists of a collection of one thousand exact digital copies of the Carter-Zimmerman polis (city state), deployed toward stars in all directions in hopes of improving humankind's understanding of the physics behind an unpredicted gamma ray burst that wiped out most of Earth's inhabitants. Vega is one of the target stars, and a C-Z polis encounters alien life on one of its planets.

Film and television

    "The Cage" (1965; aired 1988), rejected pilot episode of Star Trek: The Original Series written by Gene Roddenberry and directed by Robert Butler, as part of the film, television, and print franchise originated by Gene Roddenberry. The USS Enterprise is traveling to Vega Colony to arrange care for casualties of the hostilities on Rigel VII, when it receives a distress transmission broadcast by a scientific expedition that has vanished on Talos IV. A landing party beams down; the Talosians capture Captain Christopher Pike and plan to breed him with Vina, an expedition survivor, to create a race of slaves. Cooler heads prevail.

    "Mirror, Mirror" (1967), episode of Star Trek: The Original Series written by Jerome Bixby and directed by Marc Daniels. This episode has a transporter mishap swapping Captain Kirk and his companions with their evil counterparts in a parallel universe. In the so-called Mirror Universe, the ISS Enterprise is a ship of the Terran Empire, a dominion as evil as the United Federation of Planets is benevolent. A horrified Kirk learns that his doppelgänger is guilty of multiple atrocities, including the massacre of 5000 human colonists on the planet Vega IX.

    "One Moment of Humanity" (1976), episode of the television series Space: 1999 written by Tony Barwick and directed by Charles Crichton. When the Moon intrudes into the sphere of influence of the planet Vega, a deputation of Vegans, beautiful to behold, arrives at Moonbase Alpha to remonstrate, and ends by kidnapping two Alphans to the Vega system—abetted by telepathic ensnarement and Positronic Transfer. It turns out that the Vegans are androids, Vega is an artificial paradise planet and a prison, and the Alphans are able to liberate a human population that has been enslaved by the robots (compare following item in this article).

    Spaceballs (1987), sendup of Star Wars and other science fiction film classics[26] written by Mel Brooks et al and directed by Mel Brooks. The planet Spaceball having become uninhabitable due to an environmental catastrophe, President Skroob first attacks the peaceful planet Druidia in his own system by attempting to kidnap its princess, Vespa (compare UFO Robo Grendizer above). "Solo" operator Captain Lone Starr responds to the offer of a reward and rescues her but his plan is thwarted when he runs out of fuel and crash-lands on the nearby desert Moon of Vega. They find their way to a cave occupied by the wise old Yogurt (played by Brooks), who introduces Lone Starr to the power of "The Schwartz". The film proceeds in this vein.

    Babylon 5 (1993–1998), television series created by J. Michael Straczynski. The Vega Colony is an outpost world of the Earth Alliance in the Vega star system, which hosts at least six other planets. Vega Colony appears frequently in the series as a space voyage destination and as the location of a medical center; the ice mines on Vega VII were raided for their explosives by the mad bomber Robert Carlson.

    Contact (1997), film written by Carl Sagan and Ann Druyan, and directed by Robert Zemeckis. (see also the novel Contact above). SETI researchers detect a message from an extraterrestrial intelligence—a transmitter array orbiting Vega (compare graphic). After an arduous decoding process, they first discover, then finance (Panel member: If you were to meet these Vegans, and were permitted only one question to ask of them, what would it be?[27]) and finally implement the plans for a wormhole transport device that carries a single explorer (Ellie, played by Jodie Foster) to the center of the galaxy. There she speaks at length with a supernal sentience who manifests itself as her departed father, but she can bring back no proof of the contact—so that when she returns home few people believe her experiences actually happened.

Notes and references
Notes

    Vega rotates with a period of about 12.5 hours,[1] which is 87.6% of the speed that would cause the star to start breaking up from centrifugal effects.[2]
