Hydra is the largest of the 88 modern constellations, measuring 1303 square degrees, the longest at over 100 degrees. Its southern end abuts its northern end borders Cancer, it was included among the 48 constellations listed by the 2nd century astronomer Ptolemy. It is represented as a water snake, it should not be confused with the named constellation of Hydrus. The Greek constellation of Hydra is an adaptation of a Babylonian constellation: the MUL. APIN includes a "serpent" constellation, it is one of two Babylonian "serpent" constellations, a mythological hybrid of serpent and bird. The shape of Hydra resembles a twisting snake, features as such in some Greek myths. One myth associates it with a water snake that a crow served Apollo in a cup when it was sent to fetch water, it is associated with the monster Hydra, with its many heads, killed by Hercules, represented in another constellation. According to legend, if one of the Hydra's heads was cut off, two more would grow in its place. However, Hercules' nephew, seared the necks with a torch to prevent them from growing back and thus enabled Hercules to overcome the Hydra.
In Hindu Mythology the star that equivalents Hydra is Ashlesha. In Chinese astronomy, the stars that correspond to Hydra are located within the Vermilion Bird and the Azure Dragon; the head of Hydra was collectively known as "Min al Az'al," meaning "belonging to the uninhabited spot" in Arabic. Despite its size, Hydra contains only one moderately bright star, designated Alpha Hydrae, it is an orange giant of 177 light-years from Earth. Its traditional name means "the solitary one". Beta Hydrae is a blue-white star of 365 light-years from Earth. Gamma Hydrae is a yellow giant of 132 light-years from Earth. Hydra has one bright binary star, Epsilon Hydrae, difficult to split in amateur telescopes; the primary is a yellow star of magnitude 3.4 and the secondary is a blue star of magnitude 6.7. However, there are binary stars in Hydra. 27 Hydrae is a triple star with two components visible in binoculars and three visible in small amateur telescopes. The primary is a white star of 244 light-years from Earth.
The secondary, a binary star, appears in binoculars at magnitude 7.0 but is composed of a magnitude 7 and a magnitude 11 star. 54 Hydrae is a binary star 99 light-years from Earth divisible in small amateur telescopes. The primary is a yellow star of magnitude 5.3 and the secondary is a purple star of magnitude 7.4. N Hydrae is a pair of stars of magnitudes 5.8 and 5.9. Struve 1270 consists of a pair of stars, magnitudes 6.4 and 7.4. The other main named star in Hydra is Sigma Hydrae, which has the name of Minchir, from the Arabic for snake's nose. At magnitude 4.54, it is rather dim. The head of the snake corresponds to the Āshleshā Nakshatra, the lunar zodiacal constellation in Indian astronomy; the name of Nakshatra become the proper name of Epsilon Hydrae since 1 June 2018 by IAU. Hydra is home to several variable stars. R Hydrae is a Mira variable star 2000 light-years from Earth, it has a period of 390 days. V Hydrae is an unusually vivid red variable star 20,000 light-years from Earth, it varies in magnitude from a minimum of 9.0 to a maximum of 6.6.
Along with its notable color, V Hydrae is home to at least two exoplanets. U Hydrae is a semi-regular variable star with 528 light-years from Earth, it has a minimum magnitude of 6.6 and a maximum magnitude of 4.2. The constellation contains the radio source Hydra A. Hydra contains three Messier objects. M83 known as the high Southern Pinwheel Galaxy, is located on the border of Hydra and Centaurus, M68 is a globular cluster near M83, M48 is an open star cluster in the western end of the serpent. NGC 3242 is a planetary nebula of 1400 light-years from Earth. Discovered in 1785 by William Herschel, it has earned the nickname "Ghost of Jupiter" because of its striking resemblance to the giant planet, its blue-green disk is visible in small telescopes and its halo is visible in larger instruments.fudge M48 is an open cluster, visible to the naked eye under dark skies. Its shape has been described as "triangular". There are several globular clusters in Hydra. M68 is a globular cluster resolvable in medium amateur telescopes.
It is 31,000 light-years of the 8th magnitude. NGC 5694 is a globular cluster of 105,000 light-years from Earth. Called "Tombaugh's Globular Cluster", it is a Shapley class VII cluster. Though it was discovered as a non-stellar object in 1784 by William Herschel, its status as a globular cluster was not ascertained until 1932, when Clyde Tombaugh looked at photographic plates taken of the region near Pi Hydrae on 12 May 1931. M83, the Southern Pinwheel Galaxy, is an 8th magnitude face-on spiral galaxy, it is observed in skies south of 40°N latitude, found by using 1, 2, 3, 4 Centauri as guide stars. It has been host to six supernovae, more than any Messier object. Large amateur telescopes - a
Perseus is a constellation in the northern sky, being named after the Greek mythological hero Perseus. It is one of the 48 ancient constellations listed by the 2nd-century astronomer Ptolemy, among the 88 modern constellations defined by the International Astronomical Union, it is located near several other constellations named after ancient Greek legends surrounding Perseus, including Andromeda to the west and Cassiopeia to the north. Perseus is bordered by Aries and Taurus to the south, Auriga to the east, Camelopardalis to the north, Triangulum to the west; some star atlases during the early 19th century depicted Perseus holding the disembodied head of Medusa, whose asterism was named together as Perseus et Caput Medusae, this never came into popular usage. The galactic plane of the Milky Way passes through Perseus, whose brightest star is the yellow-white supergiant Alpha Persei, which shines at magnitude 1.79. It and many of the surrounding stars are members of an open cluster known as the Alpha Persei Cluster.
The best-known star, however, is Algol, linked with ominous legends because of its variability, noticeable to the naked eye. Rather than being an intrinsically variable star, it is an eclipsing binary. Other notable star systems in Perseus include X Persei, a binary system containing a neutron star, GK Persei, a nova that peaked at magnitude 0.2 in 1901. The Double Cluster, comprising two open clusters quite near each other in the sky, was known to the ancient Chinese; the constellation gives its name to the Perseus cluster, a massive galaxy cluster located 250 million light-years from Earth. It hosts the radiant of the annual Perseids meteor shower—one of the most prominent meteor showers in the sky; the constellation of Perseus may be derived from the Babylonian Old Man constellation associated with East in the MUL. APIN—an astronomical compilation dating to around 1000 BCE. In Greek mythology, Perseus was the son of Danaë, sent by King Polydectes to bring the head of Medusa the Gorgon — whose visage caused all who gazed upon her to turn to stone.
Perseus slew Medusa in her sleep, Pegasus and Chrysaor appeared from her body. Perseus continued to the realm of Cepheus whose daughter Andromeda was to be sacrificed to Cetus the sea monster. Perseus rescued Andromeda from the monster by killing it with his diamond sword, he turned Polydectes and his followers to stone with Medusa's head and appointed Dictys the fisherman king. Perseus and Andromeda had six children. In the sky, Perseus lies near the constellations Andromeda, Cassiopeia and Pegasus. Four Chinese constellations are contained in the area of the sky identified with Perseus in the West. Tiānchuán, the Celestial Boat, was the third paranatellon of the third house of the White Tiger of the West, representing the boats that Chinese people were reminded to build in case of a catastrophic flood season. Incorporating stars from the northern part of the constellation, it contained Mu, Psi, Alpha and Eta Persei. Jīshuǐ, the Swollen Waters, was the fourth paranatellon of the aforementioned house, representing the potential of unusually high floods during the end of August and beginning of September at the beginning of the flood season.
Lambda and Mu Persei lay within it. Dàlíng, the Great Trench, was the fifth paranatellon of that house, representing the trenches where criminals executed en masse in August were interred, it was formed by Kappa, Rho, 24, 17 and 15 Persei. The pile of corpses prior to their interment was represented by Jīshī, the sixth paranatellon of the house; the Double Cluster, h and Chi Persei, had special significance in Chinese astronomy. In Polynesia, Perseus was not recognized as a separate constellation. Algol may have been named Matohi by the Māori people, but the evidence for this identification is disputed. Matohi came into conflict with Tangaroa-whakapau over which of them should appear in the sky, the outcome affecting the tides, it matches the Maori description of a blue-white star near Aldebaran but does not disappear as the myth would indicate. Perseus is bordered by Aries and Taurus to the south, Auriga to the east and Cassiopeia to the north, Andromeda and Triangulum to the west. Covering 615 square degrees, it ranks twenty-fourth of the 88 constellations in size.
It appears prominently in the northern sky during the Northern Hemisphere's spring. Its main asterism consists of 19 stars; the constellation's boundaries, as set by Eugène Delporte in 1930, are defined by a 26-sided polygon. In the equatorial coordinate system, the right ascension coordinates of these borders lie between 01h 29.1m and 04h 51.2m, while the declination coordinates are between 30.92° and 59.11°. The International Astronomical Union adopted the three-letter abbreviation "Per" for the constellation in 1922. Algol known by its Bayer designation Beta Persei, is the best-known star in Perseus. Representing the head of the Gorgon Medusa in Greek mythology, it was called Horus in Egyptian mythology and Rosh ha Satan in Hebrew. Located 92.8 light-years from Earth, it varies in apparent magnitude from a minimum of 3.5 to a maximum of 2.3 over a period of 2.867 days. The star system is the prototype of a group of eclipsing binary stars named Algol variables, though it has a third member to make up what is a triple star system.

Sidney Hall was a British engraver and cartographer well known and popular for his early nineteenth century atlases containing maps of the United Kingdom and of the ancient world reproduced from Hall's engravings. Hall made engravings for a number of international atlases at a time when cartography and atlases were popular, he engraved a series of cards for the various constellations, published c.1825 in a boxed set called Urania's Mirror.

Rugby School is a day and boarding co-educational independent school in Rugby, England. Founded in 1567 as a free grammar school for local boys, it is one of the oldest independent schools in Britain. Up to 1667, the school remained in comparative obscurity, its re-establishment by Thomas Arnold during his time as Headmaster, from 1828 to 1841, was seen as the forerunner of the Victorian public school. It is one of the original seven Great Nine Public Schools defined by the Clarendon Commission of 1864. Rugby School was the birthplace of Rugby football. In 1845, three Rugby School pupils produced the first written rules of the "Rugby style of game"; as the nature of the school shifted, a new school – Lawrence Sheriff Grammar School – was founded in 1878 to continue Lawrence Sheriff's original intentions. Rugby expanded further in the 20th century and new buildings were built inspired by the Edwardian Era; the Temple Speech Room, named after former headmaster and Archbishop of Canterbury Frederick Temple is now used for whole-School assemblies, speech days, musicals – and BBC Mastermind.
Between the wars, the Memorial Chapel, the Music Schools and a new Sanatorium appeared. In 1975 three girls were admitted into the sixth form, the first girls’ house opened 3 years followed by three more. In 1992, the first 13-year-old girls arrived, in 1995 Rugby had its first-ever Head Girl, Louise Woolcock, who appeared on the front page of The Times. In September 2003 a last girls’ house was added. Today, total enrolment of day pupils, from forms 4 to 12, numbers around 800. Rugby School was founded in 1567 as a provision in the will of Lawrence Sheriff, who had made his fortune supplying groceries to Queen Elizabeth I of England. Since Lawrence Sheriff lived in Rugby and the neighbouring Brownsover, the school was intended to be a free grammar school for the boys of those towns. Up to 1667, the school remained in comparative obscurity, its history during that trying period is characterised by a series of lawsuits between the Howkins family, who tried to defeat the intentions of the testator, the masters and trustees, who tried to carry them out.
A final decision was handed down in 1667, confirming the findings of a commission in favour of the trust, henceforth the school maintained a steady growth. "Floreat Rugbeia" is the traditional school song. Pupils beginning Rugby in the F Block study various subjects. In a pupil's second year, they do nine subjects which are for their GCSEs, this is the same for the D Block; the school provides standard A-levels in 29 subjects. Students at this stage have the choice of taking three or four subjects and are offered the opportunity to take an extended project; the Governing Body provides financial benefits with school fees to families unable to afford them. Parents of pupils who are given a Scholarship are capable of obtaining a 10% fee deduction, although more than one scholarship can be awarded to one student. Rugby School claims its goal is to give pupils more than education with a new tagline being'Whole Person, Whole Point'; the school has many traditions including two annual carol services, as well as the pushcart race, an event in which the entire school competes, with each house designing and racing their own cart.
This race has been won by School house every year since 2012. The school has three magazines: Quod, it was no longer desirable to have only local boys attending and the nature of the school shifted, so a new school – Lawrence Sheriff Grammar School – was founded in 1878 to continue Lawrence Sheriff's original intentions. The core of the school was completed in 1815 and is built around the Old Quad, with its Georgian architecture. Notable rooms are the Upper Bench, the Old Hall of School House, the Old Big School. Thomas Hughes once carved his name on the hands of the school clock, situated on a tower above the Old Quad; the polychromatic school chapel, new quadrangle, Temple Reading Room, Macready Theatre and Gymnasium were designed by well-known Victorian Gothic revival architect William Butterfield in 1875, the smaller Memorial Chapel was dedicated in 1922. By the twentieth century Rugby expanded and new buildings were built inspired by this Edwardian Era; the Temple Speech Room, named after former headmaster and Archbishop of Canterbury Frederick Temple and now used for whole-School assemblies, speech days, musicals – and BBC Mastermind.
Oak-panelled walls boast the portraits of illustrious alumni, including Neville Chamberlain holding his piece of paper. Between the wars, the Memorial Chapel, the Music Schools and a new Sanatorium appeared. In 2005, Rugby School was one of fifty of the country's leading independent schools found guilty of running an illegal price-fixing cartel allowing them to drive up fees for thousands of parents; each school was required to pay a nominal penalty of £10,000 and all agreed to make ex-gratia payments totalling three million pounds into a trust designed to benefit pupils who atte
Pyxis is a small and faint constellation in the southern sky. Abbreviated from Pyxis Nautica, its name is Latin for a mariner's compass. Pyxis was introduced by Nicolas-Louis de Lacaille in the 18th century, is counted among the 88 modern constellations; the plane of the Milky Way passes through Pyxis. A faint constellation, its three brightest stars—Alpha and Gamma Pyxidis—are in a rough line. At magnitude 3.68, Alpha is the constellation's brightest star. It is a blue-white star 880 light-years distant and around 22,000 times as luminous as the Sun. Pyxis is located close to the stars that formed the old constellation Argo Navis, the ship of Jason and the Argonauts. Parts of Argo Navis were the Carina, the Puppis, the Vela; these became their own constellations. In the 19th century, John Herschel suggested renaming Pyxis to Malus but the suggestion was not followed. T Pyxidis, located about 4 degrees northeast of Alpha Pyxidis, is a recurrent nova that has flared up to magnitude 7 every few decades.
Three star systems in Pyxis have confirmed exoplanets. The Pyxis globular cluster is situated about 130,000 light-years away in the galactic halo; this region was not thought to contain globular clusters. The possibility has been raised. In ancient Chinese astronomy, Alpha and Gamma Pyxidis formed part of Tianmiao, a celestial temple honouring the ancestors of the emperor, along with stars from neighbouring Antlia; the French astronomer Nicolas-Louis de Lacaille first described the constellation in French as la Boussole in 1752, after he had observed and catalogued 10,000 southern stars during a two-year stay at the Cape of Good Hope. He devised fourteen new constellations in uncharted regions of the Southern Celestial Hemisphere not visible from Europe. All but one honoured instruments that symbolised the Age of Enlightenment. Lacaille Latinised the name to Pixis Nautica on his 1763 chart; the Ancient Greeks identified the four main stars of Pyxis as the mast of the mythological Jason's ship, Argo Navis.
German astronomer Johann Bode defined the constellation Lochium Funis, the Log, Line—a nautical device once used for measuring speed and distance travelled at sea—around Pyxis in his 1801 star atlas, but the depiction did not survive. In 1844 John Herschel attempted to resurrect the classical configuration of Argo Navis by renaming it Malus the Mast, a suggestion followed by Francis Baily, but Benjamin Gould restored Lacaille's nomenclature. Covering 220.8 square degrees and hence 0.535% of the sky, Pyxis ranks 65th of the 88 modern constellations by area. Its position in the Southern Celestial Hemisphere means that the whole constellation is visible to observers south of 52°N, it is most visible in the evening sky in March. A small constellation, it is bordered by Hydra to the north, Puppis to the west, Vela to the south, Antlia to the east; the three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is'Pyx'. The official constellation boundaries, as set by Eugène Delporte in 1930, are defined by a polygon of eight sides.
In the equatorial coordinate system, the right ascension coordinates of these borders lie between 8h 27.7m and 9h 27.6m, while the declination coordinates are between −17.41° and −37.29°. Lacaille gave Bayer designations to ten stars now named Alpha to Lambda Pyxidis, skipping the Greek letters iota and kappa. Although a nautical element, the constellation was not an integral part of the old Argo Navis and hence did not share in the original Bayer designations of that constellation, which were split between Carina and Puppis. Pyxis is a faint constellation, its three brightest stars—Alpha and Gamma Pyxidis—forming a rough line. Overall, there are 41 stars within the constellation's borders with apparent magnitudes brighter than or equal to 6.5. With an apparent magnitude of 3.68, Alpha Pyxidis is the brightest star in the constellation. Located 880 ± 30 light-years distant from Earth, it is a blue-white giant star of spectral type B1.5III, around 22,000 times as luminous as the Sun and has 9.4 ± 0.7 times its diameter.
It began life with a mass 12.1 ± 0.6 times that of the Sun 15 million years ago. Its light is dimmed by 30% due to interstellar dust, so would have a brighter magnitude of 3.31 if not for this. The second brightest star at magnitude 3.97 is Beta Pyxidis, a yellow bright giant or supergiant of spectral type G7Ib-II, around 435 times as luminous as the Sun, lying 420 ± 10 light-years distant away from Earth. It has a companion star of magnitude 12.5 separated by 9 arcseconds. Gamma Pyxidis is a star of magnitude 4.02. It is an orange giant of spectral type K3III that has cooled and swollen to 3.7 times the diameter of the Sun after exhausting its core hydrogen. Kappa Pyxidis was catalogued but not given a Bayer designation by Lacaille, but Gould felt the star was bright enough to warrant a letter. Kappa is 560 ± 50 light-years distant. An orange giant of spectral type K4/K5III, Kappa has a luminosity 965 times that of the Sun, it is separated by 2.1 arcseconds from a magnitude 10 star. Theta Pyxidis is a red giant of spectral type M1III and semi-regular variable with two measured periods of 13 and 98.3 days, an average magnitude of 4.71, is 500 ± 30 light-years distant from Earth.
It has expanded to 54 times the diameter of the Sun. Located around 4 degrees northeast of Alpha is T Pyxidis, a binary star system composed o
Urania was, in Greek mythology, the muse of astronomy. Urania was the daughter of Zeus by Mnemosyne and a great granddaughter of Uranus; some accounts list her as the mother of the musician Linus by Apollo or Amphimarus, son of Poseidon, Hymenaeus is said to have been a son of Urania. Urania is associated with Universal Love and the Holy Spirit. Sometimes identified as the eldest of the divine sisters, Urania inherited Zeus' majesty and power and the beauty and grace of her mother Mnemosyne. Urania dresses in a cloak embroidered with stars and keeps her eyes and attention focused on the Heavens, she is represented with a celestial globe to which she points with a little staff. She is able to foretell the future by the arrangement of the stars; those who are most concerned with philosophy and the heavens are dearest to her. Those who have been instructed by her she raises aloft to heaven, for it is a fact that imagination and the power of thought lift men's souls to heavenly heights. Urania, o'er her star-bespangled lyre,With touch of majesty diffused her soul.
In the invocation to Book 7 of John Milton's epic poem Paradise Lost, the poet invokes Urania to aid his narration of the creation of the cosmos, though he cautions that it is "he meaning, not the name I call" Urania is the namesake for astronomical observatories in Berlin, Bucharest, Zurich and Uraniborg on the island of Hven. The main belt asteroid 30 Urania was named after her. There is Polish astronomical magazine Urania - Postępy Astronomii, which emerged from "Urania" and "Postępy Astronomii" magazines. In University of São Paulo, the logo of the Institute of Astronomy and Atmospheric Sciences used to bear Urania; the official seal of the U. S. Naval Observatory portrays Urania. Hr. Ms. Urania is a sail training vessel for the Royal Netherlands Naval College. There has been a Hr. Ms. Urania in the Royal Netherlands Navy since 1832. Urania is the name traditionally given to the eighth book of Herodotus' Histories. Urania is an epithet given to Aphrodite in contrast with her other aspect Aphrodite Pandemos.
Urania Cottage was a refuge for fallen women established by the writer Charles Dickens in Lime Grove, Shepherd's Bush, London in the late 1840s. The funding was provided by millionaire and philanthropist Angela Burdett-Coutts, of the well-known banking family; some of the inmates may have provided inspiration for certain of the female characters in Dickens' novels. At Columbia University, toward the end of 18th century, the Urania Society was created for the improvement of oratory and literary skills. DeWitt Clinton was a member. Urania Street is situated between Felicity streets in New Orleans. Urania is a name of the sports hall in Olsztyn. Muse magazine, until 2015 when the magazine was revamped, featured Urania as one of the characters in the "Kokopelli and Co." comic strip by Larry Gonick published in each issue of the magazine. She was the only original muse; the other Old Muses were said to be living in a retirement home. Urania is the name of a popular female-fronted rock band in Honduras.
Urania is used as the muse in Paradise Lost books 7 and 9. Urania is invoked in Shelley's "Adonais."'To Urania' is a poem, a book of poetry by Joseph Brodsky nytimes Urania is the title character in Lady Mary Wroth's 17th-century novel The Countess of Montgomery's Urania.

Cepheus is a constellation in the northern sky, named after Cepheus, a king of Aethiopia in Greek mythology. Cepheus was one of the 48 constellations listed by the second century astronomer Ptolemy, it remains one of the 88 constellations in the modern times; the constellation's brightest star is Alpha Cephei, with an apparent magnitude of 2.5. Delta Cephei is the prototype of an important class of star known as a Cepheid variable. RW Cephei, an orange hypergiant, together with the red supergiants Mu Cephei, MY Cephei, VV Cephei, V354 Cephei are among the largest stars known. In addition, Cepheus has the hyperluminous quasar S5 0014+81, which hosts an ultramassive black hole in its core, reported at 40 billion solar masses, about 10,000 times more massive than the central black hole of the Milky Way, making this among the most massive black holes known. Cepheus was the King of Aethiopia, he was married to Cassiopeia and was the father of Andromeda, both of whom are immortalized as modern day constellations along with Cepheus.
Alpha Cephei known as Alderamin, is the brightest star in the constellation, with an apparent magnitude of 2.51. Delta Cephei is the prototype Cepheid variable, a yellow-hued supergiant star 980 light-years from Earth, it was discovered to be variable by John Goodricke in 1784. It varies between 3.5 4.4 m over a period of 5 days and 9 hours. The Cepheids are a class of pulsating variable stars, it is a double star. There are three red giants in the constellation. Mu Cephei is known as Herschel's Garnet Star due to its deep red colour, it is a semiregular variable star with a minimum magnitude of 5.1 and a maximum magnitude of 3.4. Its period is 2 years; the star is around 5.64 AU in radius. If it were placed at the center of the Solar System, it would extend to the orbit of Jupiter. Another, VV Cephei A, like Mu Cephei, is a red supergiant and a semiregular variable star, located at least 5,000 light-years from Earth, it has a minimum magnitude of 5.4 and a maximum magnitude of 4.8, is paired with a blue main sequence star called VV Cephei B.
One of the largest stars in the galaxy, it has a diameter 1,400 times that of the Sun. VV Cephei is an unusually long-period eclipsing binary, but the eclipses, which occur every 20.3 years, are too faint to be observed with the unaided eye. T Cephei a red giant, is a Mira variable with a minimum magnitude of 11.3 and a maximum magnitude of 5.2, 685 light-years from Earth. It has a diameter of between 329 to 500 solar diameters. There are binary stars in Cepheus. Omicron Cephei is a binary star with a period of 800 years; the system, 211 light-years from Earth, consists of an orange-hued giant primary of magnitude 4.9 and a secondary of magnitude 7.1. Xi Cephei is 102 light-years from Earth, with a period of 4,000 years, it has a blue-white primary of magnitude 4.4 and a yellow secondary of magnitude 6.5. Kruger 60 is an 11th-magnitude binary star consisting of two red dwarfs; the star system is one of the nearest. NGC 188 is an open cluster that has the distinction of being the closest open cluster to the north celestial pole, as well as one of the oldest-known open clusters.
NGC 6946 is a spiral galaxy in which ten supernovae have been observed, more than in any other galaxy. IC 469 is another spiral galaxy, characterized by a compact nucleus, of oval shape, with perceptible side arms; the nebula NGC 7538 is home to the largest-yet-discovered protostar. NGC 7023 is a reflection nebula with an associated star cluster; the nebula and cluster are located near T Cephei. S 155 known as the Cave Nebula, is a dim and diffuse bright nebula within a larger nebula complex containing emission and dark nebulosity; the quasar 6C B0014+8120 is one of the most powerful objects in the universe, powered by a supermassive black hole equivalent to 40 billion Suns. Cepheus is most depicted as holding his arms aloft, praying for the deities to spare the life of Andromeda, he is depicted as a more regal monarch sitting on his throne. In Chinese astronomy, the stars of the constellation Cepheus are found in two areas: the Purple Forbidden enclosure and the Black Tortoise of the North. In the TV sitcom 3rd Rock from the Sun, the aliens' home planet is stated to be located in a barred spiral galaxy on the Cepheus-Draco border.
One antagonist of the video game Mega Man Star Force is a character named King Cepheus. Contextually, the constellation Cepheus is the one referenced by this name; the Canadian musician Deadmau5 named his song "HR 8938 Cephei" after a star in the constellation. An end-of-game boss in the video game Lovers in a Dangerous Spacetime is called King Cepheus, after the constellation. USS Cepheus and USS Cepheus, United States Navy ships.
