The subject became especially popular in the 19th century. It is located about 1,027 light-years from Earth, is about 2 million years old,[74] and contains many stars with circumstellar disks. La costellazione di Andromeda (in latino Andromeda, genitivo Andromedae, abbreviata in And) è una delle 18 costellazioni dell'emisfero boreale (emisfero nord). Like Mercury, he wears winged boots, and also a winged helmet. nr. [87] These bubbles create sound waves that travel through the Perseus Cluster, sounding a B flat 57 octaves below middle C.[87] This galaxy is a cD galaxy that has undergone many galactic mergers throughout its existence, as evidenced by the "high velocity system"—the remnants of a smaller galaxy—surrounding it. The galactic plane of the Milky Way passes through Perseus, whose brightest star is the yellow-white supergiant Alpha Persei (also called Mirfak), which shines at magnitude 1.79. [35] With an apparent magnitude of 6.72, it is too dim to be seen with the naked eye even in perfectly dark conditions. La costellazione si individua con facilità, trovandosi a nordest del brillante asterismo del Quadrato di Pegaso, di cui la stella al vertice nordorientale fa parte di Andromeda; la costellazione si estende poi a nord e ad est del Quadrato, seguendo un allineamento di stelle di seconda e terza magnitudine, arrivando sin quasi a lambire la scia luminosa della Via Lattea del nord. Mappa della costellazione di Andromeda ( vedi immagine ingrandita). In 1798 it was valued at 700 guineas but failed to sell, selling for 310 gn. La giovane, mentre aspettava la sua triste fine legata ad una roccia, fu improvvisamente salvata dall'arrivo di Perseo che la [10], When Andromeda was moved to the left of the painting her pose was different from the final painting, more similar to the original one when she was on the right. Extensive searches have failed to find evidence of it having a planetary system.

[78] It is very difficult to observe visually because its low surface brightness makes it appear dimmer than most other emission nebulae. It was painted in 1554–1556 as part of a series of mythological paintings called "poesie" ("poetry") intended for King Philip II of Spain.The paintings took subjects from the Roman poet Ovid's Metamorphoses, in this case Book IV, lines 663–752, and all featured female nudes. It is the brightest star (as seen from Earth) of a moving group of bright blue-white giant and supergiant stars, the Perseus OB2 Association or Zeta Persei Association. Andromeda era già stata promessa a suo zio Fineo, il quale, alla testa di un gran numero di uomini armati, interruppe la festa e tentò di rapire la fanciulla. V718 Persei is a star in the young open cluster IC 348 that appears to be periodically eclipsed by a giant planet every 4.7 years. [54] The Double Cluster contains three even larger stars, each over 700 solar radii:[55] S, RS, and SU Persei are all semiregular pulsating M-type supergiants. IN CIELO C'E' UNA STELLA In cielo c’è una stella per ognuno di noi. He sees a painting by Paolo Veronese in Rennes as a paraphrase of this version. View the interactive image by AuroraPaini. In Greek mythology, Perseus was the son of Danaë, who was sent by King Polydectes to bring the head of Medusa the Gorgon—whose visage caused all who gazed upon her to turn to stone. Andromeda è una costellazione rappresentante la principessa Andromeda, che si trova nell'emisfero nord vicino a Pegaso. [33], Zeta Persei is the third-brightest star in the constellation at magnitude 2.86. [2] It is located near several other constellations named after ancient Greek legends surrounding Perseus, including Andromeda to the west and Cassiopeia to the north. At an estimated distance of 1,475 light-years from Earth, the system is now thought to lie too far from the center of the Zeta Persei group to belong to it. Perseo era un eroe nato, secondo il mito, da Zeus e Danae.Il bisnonno materno Abante, re dell’Argolide, e la moglie Euridice avevano avuto una figlia, Danae, madre di Perseo. In questo tratto di cielo il mito si completa con la figura di Cefeo, re e sposo di Cassiopea, la cui costellazione ne è a nord-ovest. La costellazione di Perseo a sinistra tramite Stellarium, a destra una foto reale. [63] This has been inferred to be an object with a maximum mass of 6 times that of Jupiter and an orbital radius of 3.3 AU. Its helium has been fused into heavier elements and its core is composed of carbon and oxygen. It was listed among his paintings on his death in London in 1641, and bought in 1646 by one of van Dyck's best customers, Algernon Percy, 10th Earl of Northumberland, together with Titian's Portrait of the Vendramin Family (now National Gallery).

The painting is in oils on canvas, and measures 175 x 189.5 cm. Ci appartiene come dono dalla scienza. Il mito di Perseo. [17] Perseo è una costellazione di dimensioni medio-grandi, estesa fra Andromeda e il brillante pentagono dell'Auriga; è composta da 136 stelle visibili a occhio nudo, molte delle quali riunite in tre gruppi di stelle, il più notevole dei quali è quello di Mirfak (o Algenib, α Persei), verso nord e coincidente con una brillante associazione stellare. It's where your interests connect you with your people. [66] This segment is towards the rim of the galaxy. [18] The brightest component is a blue-white main-sequence star of spectral type B8V,[19] which is 3.5 times as massive and 180 times as luminous as the Sun. It is one of the 48 ancient constellations listed by the 2nd-century astronomer Ptolemy,[1] and among the 88 modern constellations defined by the International Astronomical Union (IAU). Alzando lo sguardo sopra le nostre teste, ad ottobre e novembre, impera una costellazione ricca di astri brillanti: quella di Perseo. At an advanced stage of stellar evolution, it is a red giant that has expanded for the second time to have a radius around 150 times that of our Sun. M76 is a planetary nebula, also called the Little Dumbbell Nebula. In Greek mythology, the kingdom of Ethiopia was ruled by the beautiful but vain queen, Cassiope; she maintained that her beauty, and that of her daughter Andromeda, was superior to that of the sea nymphs, who were the daughters of Poseidon, the god of the sea. Rearick, W. R. "Titian's Later Mythologies." [16] In 1654 it was in the Paris house of the politician Louis Phélypeaux, seigneur de La Vrillière, where it remained until 1717, sold with the house in 1705. Figura 3. Perseus is a constellation in the northern sky, being named after the Greek mythological hero Perseus. It was the host galaxy of the supernova SN 2006gy, one of the brightest ever recorded. It is the brightest member of the Alpha Persei Cluster (also known as Melotte 20 and Collinder 39), which is an open cluster containing many luminous stars. Other notable star systems in Perseus include X Persei, a binary system containing a neutron star, and GK Persei, a nova that peaked at magnitude 0.2 in 1901. The Hermitage Museum has a copy that probably once belonged to Prince Eugene of Savoy. The Musée Ingres in Montauban, France has a 17th-century copy once in the Palace of Versailles, where it was recorded in 1683.[15]. Perseo è un grande eroe della mitologia greca meglio conosciuto per la sua decapitazione intelligente della Medusa, il mostro che ha compiuto tutti coloro che guardò il suo viso nella pietra. Dopo la morte di Andromeda, intorno al 412 a.C. come viene riferito da Euripide, la dea Atena la trasformo in una costelazione collocata al cielo boreale, vicino alle costellazioni di Perseo e di Cassiopea. Mappa della costellazione di Perseo ( vedi immagine ingrandita). Sorvolando le coste etiopi, Perseo, di ritorno dall’impresa contro Medusa, vide Andromeda incatenata ad uno scoglio; colpito dalla sua bellezza si fermò per aiutarla. Perseo Nell’emisfero boreale si susseguono in una specie di gigantesco semicerchio cinque costellazioni a rappresentare nel cielo l’epopea di Perseo: Cefeo, Cassiopea, Perseo, che è nel centro, Andromeda e infine Pegaso, il cavallo alato. Ella sposò Cefeo, re di Etiopia e da loro nacque Andromeda. An 1870 inventory records it in the "Lumber Room" there, described as by Domenichino, and Ingamells notes disapprovingly that "between 1876 and 1897 [it] hung unglazed over a bath in Sir Richard Wallace's dressing room", before being correctly identified and rescued from the steam. Poi continuare la linea ad est, e si punta alla stella di Perseo. This star is very similar to our Sun, shining with 2.2 times its luminosity. [3], Titian follows Ovid fairly closely, although it is likely that his Latin was poor, and he mainly relied on somewhat simplified versions in Italian, of which there was a choice. The painting is well-travelled; painted in Venice, it was delivered in modern Belgium, then went to Spain, Italy, England, and France before returning to England. 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. Perseus and Andromeda is a painting by the Italian Renaissance artist Titian, now in the Wallace Collection in London. [56][57][58] The stars are not visible to the naked eye; SU Persei, the brightest of the three, has an apparent magnitude of 7.9[58] and thus is visible through binoculars. Questa statua del Perseo con la testa di Medusa, si trova nella Loggia de’ Lanzi a Firenze; scolpita dall'artista Benvenuto Cellini. Acrisio temeva per le sorti del suo regno, perché non avendo avuto figli maschi, non sapeva a chi lasciare il trono. Il periodo migliore per osservarla è l'autunno. [10] Jīshuǐ (積水), 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. Costellazione di Andromeda . When the nymphs became aware of her claims, they protested to their father, who retaliated by calling up a Cetus or sea monster to ravage the coastline of Ethiopia placing Cassiope's kingdom at risk. Il tema della liberazione di Andromeda ad opera dell'eroe Perseo, caro alla pittura domestica pompeiana, simboleggiava la virtus dell'eroe, messa alla prova dal combattimento contro il mostro marino, e la castità della giovane sposa promessa. Cefeo sta dietro la schiena dell’Orsa Minore ed è compreso nel circolo artico dai piedi fino al petto, in modo tale che solo le spalle e la testa sembrano tramontare. [15], The painting was certainly in the collection of Anthony van Dyck, who may have acquired it from the Leoni family, who were based in Milan, during his years in Italy from 1621 to 1627. [22], The 1815 sale was the last time the painting came to the market. [36] The system is an X-ray source and the primary star appears to be undergoing substantial mass loss. [84] NGC 1260 is either a lenticular or tightly-wound spiral galaxy about 76.7 million ly (23.5 million pc) from Earth. In Ovid Andromeda's parents are nearby; here they are probably on the shore opposite, by a city. It is a member of the Perseus Cluster (Abell 426),[85] a massive galaxy cluster located 76.6 million ly (23.5 million pc) from Earth. It was painted in 1554–1556 as part of a series of mythological paintings called "poesie" ("poetry") intended for King Philip II of Spain. [7] In the sky, Perseus lies near the constellations Andromeda, Cepheus, Cassiopeia (Andromeda's mother), Cetus, and Pegasus. [72] M34 can be resolved with good eyesight but is best viewed using a telescope at low magnifications. [77] NGC 1499, also known as the California Nebula, is an emission nebula that was discovered in 1884–85 by American astronomer Edward E. Andromeda come costellazione. Costellazione di Andromeda e Perseo (considerato da noi sozdvezdie) si trovano nelle vicinanze. Il settore celeste che ospita Andromeda racchiude anche i personaggi legati al suo mito: la madre Cassiopea, il padre Cefeo, l’eroe Perseo che salvò la giovane e Pegaso, il cavallo alato su cui questi viaggiava. Incorporating stars from the northern part of the constellation, it contained Mu, Delta, Psi, Alpha, Gamma and Eta Persei.

It is one of the 48 ancient constellations listed by the 2nd-century astronomer Ptolemy, and among the 88 modern constellations defined by the International Astronomical Union. e se le legò ai piedi, si cinse della ricurva spada IC 348 is a somewhat young open cluster that is still contained within the nebula from which its stars formed. Both of these were repetitions with variations of compositions Titian had already painted in the previous decade for the Farnese family in Rome. It hosts the radiant of the annual Perseids meteor shower—one of the most prominent meteor showers in the sky. Per quanto riguarda le prime, oltre alle più celebri zeta Persei e epsilon Persei vi è anche tau Persei, una stella gialla di magnitudine 3,9 la cui distanza dal nostro sistema solare è di duecentocinquantaquattro anni. Perseo è una costellazione di dimensioni medio-grandi, estesa fra Andromeda e il brillante pentagono dell'Auriga; è composta da 136 stelle visibili a occhio nudo, molte delle quali riunite in tre gruppi di stelle, il più notevole dei quali è quello di Mirfak (o Algenib, α Persei), verso nord e coincidente con una brillante associazione stellare. [24], The painting was not copied by Titian or his workshop, as the first two poesie were, but later copies exist. L'eroe Perseo, che già aveva ucciso la Medusa, passando a volo di là in arcione a Pegaso, il suo cavallo alato, vide la ragazza e se ne innamorò a prima vista: chiese al padre di lei la sua mano se avesse sconfitto il mostro, e il re di Etiopia acconsentì. The Leoni family may have bought it when the collections of Pérez were dispersed. 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°. AG Persei is another Algol variable in Perseus, whose primary component is a B-type main sequence star with an apparent magnitude of 6.69. On the advice of Jupiter Ammon, the Queen, together with her husband Cepheus, decided to sacrifice her daughter Andromeda to the monster. Perseus is also bordered by Aries and Taurus to the south, Auriga to the east, Camelopardalis to the north, and Triangulum to the west. 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 actually a triple star system. Natura mitologica Per i Greci era la figlia di Cefeo e Cassiopea, destinata in sacrificio ad un mostro marino inviato dal dio Nettuno. La stella è [13], Perseus is bordered by Aries and Taurus to the south, Auriga to the east, Camelopardalis and Cassiopeia to the north, and Andromeda and Triangulum to the west. [79] NGC 1333 is a reflection nebula and a star-forming region. Proseguendo nella stessa direzione tracciata dalle stelle più luminose di Andromeda si raggiunge Perseo, una costellazione molto più ricca delle precedenti in quanto si trova lungo il piano della Via Lattea, stretta fra le brillanti costellazioni di Cassiopea, a nordovest, e l’Auriga, a est. [22] Phi Persei is a double star, although the two components do not eclipse each other. [70] The clusters are both distinct from the surrounding star field and are clearly concentrated at their centers. Four Chinese constellations are contained in the area of the sky identified with Perseus in the West. [18] The tertiary component is a main sequence star of type A7,[21] which is located on average 2.69 AU from the other two stars. La costellazione ha la forma approssimata di una lettera «A» allungata, debole e deformata. [32] Of magnitude 4.05, nearby Iota Persei has been considered a member of the group, but is actually located a mere 34 light-years distant. [11] The Double Cluster, h and Chi Persei, had special significance in Chinese astronomy. There are records of paintings of the subject in the collections of Pérez in 1585–86 (described as "grande" or large), of Leon Bautista Leoni on his death in 1605 ("a damaged Andromeda by Titian") and of his father Pompeo Leoni on his death in 1608 (described as large, and by Titian). [6] In a letter from Titian to Philip accompanying the Venus and Adonis, he noted that the pair offered contrasting poses, and promised "another different view" in both Perseus and Andromeda and a Jason and Medea he intended to produce. [6] Perseus continued to the realm of Cepheus whose daughter Andromeda was to be sacrificed to Cetus the sea monster. Covering 615 square degrees, it ranks twenty-fourth of the 88 constellations in size. Some star atlases during the early 19th century also depicted Perseus holding the disembodied head of Medusa,[3] whose asterism was named together as Perseus et Caput Medusae;[4] however, this never came into popular usage. Perseus rescued Andromeda from the monster by killing it with his sword. Between 1842 and about 1854 it was stored in the Pantechnicon repository in London, before moving to Hertford House, now home of the Wallace Collection, where it has remained. NGC 1023 is a barred spiral galaxy of magnitude 10.35, around 30 million light-years (9.2 million parsecs) from Earth. The many paintings of the subject in later centuries tended to follow Titian's reduction of the subject to the two main figures and the monster, although not copying his composition. It was probably one already described as "damaged" in 1605, and has suffered subsequent damages, as well as apparently being cut down along all the sides. The constellation's boundaries, as set by Belgian astronomer Eugène Delporte in 1930, are defined by a 26-sided polygon. [68][69] Both lie more than 7,000 light-years from Earth and are several hundred light-years apart. [65], Within the Perseus Arm lie two open clusters (NGC 869 and NGC 884) known as the Double Cluster. The two are Trumpler class I 3 r clusters, though NGC 869 is a Shapley class f and NGC 884 is a Shapley class e cluster. Its jets, caused by the supermassive black hole at its center, extend several million light-years in opposing directions, making them some of the largest objects in the universe. [17], It then joined the famous Orleans Collection of Philippe II, Duke of Orléans, Regent of France,[18] to be re-united with four others of Titian's poesie, and two other versions by Titian of Venus and Adonis. Titolo dell'episodio: Perseo e Andromeda. [47] Xi Persei, traditionally known as Menkhib,[48] a blue giant of spectral type O7III, is one of the hottest bright stars in the sky,[49] with a surface temperature of 37,500 K. It is one of the more massive stars, being between 26 and 32 solar masses,[49][50] and is 330,000 times as luminous as our Sun. Lambda and possibly Mu Persei lay within it. These were to be the first original compositions in the series for Philip, but there is no trace of the Jason and Medea, which was presumably abandoned. [4], Various visual sources have been suggested, both from the rather crude woodcut illustrations of various editions of Ovid, and specific classical reliefs, as well as a well-known drawing by Michelangelo of the Risen Christ (British Museum). Perseus is a constellation in the northern sky, being named after the Greek mythological hero Perseus. An engraving by the Venetian Ferrando Bertelli probably dates to the 1550s and is a close rendering, though extending the composition on all sides except the left, possibly reflecting the original size of the painting, which has been cut down to an unknown extent. Andromeda è formata da tre stelle di seconda magnitudine, una delle quali costituisce il vertice nord-orientale del Quadrato di Pegaso. Visualizza altre idee su Egitto, Peter paul rubens, Costellazioni. At first Andromeda was on the right, in a fairly similar pose, but leaning from left to right as in the final picture.

The arm to the left was raised above her head in a similar fashion, but the other arm more or less horizontal, and the head presumably looking to the centre. [76], There are many nebulae in Perseus. Rather than being an intrinsically variable star, it is an eclipsing binary. It appears to have left the Spanish royal collection before Philip's death in 1598 (the only poesie to do so), but was replaced by a careful copy, now in Gerona, Spain. [89] The September Epsilon Perseids, discovered in 2012, are a meteor shower with an unknown parent body in the Oort cloud. L'associazione Andromeda è un Club polifunzionale per soci Andromeda, in astronomy, constellation of the northern sky at about one hour right ascension and 40° north declination. Doppio ammasso di stelle nella costellazione del Perseo - Buy this stock photo and explore similar images at Adobe Stock The constituent stars, numbering over 100 in each cluster, range widely in brightness. In Polynesia, Perseus was not commonly recognized as a separate constellation; the only people that named it were those of the Society Islands, who called it Faa-iti, meaning "Little Valley". Andromeda è un nome dalle m o lte valenze: di una principessa della mitologia greca, di una costellazione, della galassia più vicina alla Via Lattea, di un fiore raro delle torbiere di montagna. Add text, web link, video & audio hotspots on top of your image and 360 content. It faded to magnitude 13 around 30 years after its peak brightness. [82], Perseus contains some notable galaxies. Ha anche salvato Andromeda dal mostro marino. The Double Cluster, comprising two open clusters quite near each other in the sky, was known to the ancient Chinese. I genitori della fanciulla erano Cassiopea (la madre) e Cefeo (il padre). 23, This page was last edited on 2 December 2020, at 22:31. [73] It contains about 100 stars scattered over a field of view larger than that of the full moon. [88], The Perseids are a prominent annual meteor shower that appear to radiate from Perseus from mid-July, peaking in activity between 9 and 14 August each year. The book illustrations "all show Perseus wearing a winged helmet like Mercury, for which there is no textual justification, and carrying a small baroque parade shield, features which Titian may later have remembered. A supergiant of spectral type F5Ib located around 590 light-years away from Earth,[24] Mirfak has 5,000 times the luminosity and 42 times the diameter of our Sun. Google Arts & Culture features content from over 2000 leading museums and archives who have partnered with the Google Cultural Institute to bring the world's treasures online. One component is a red dwarf star of spectral type M4.5V,[42] which orbits a mysterious dense and heavy object—possibly a black hole—every 5.1 hours. Mentre Perseo passa in volo sulla spiaggia dell’Etiopia, dopo aver preso la testa di Medusa, vede Andromeda incatenata fra le onde (τό κῦμα - κύματος) ad uno scoglio abbandonato del mare ed è colpito dalla sorprendente vista. 8998). ANDROMEDA ('Ανδρόμέδα, Andromĕda).. - Figlia di Cefeo e di Cassiopea. [12] Algol may have been named Matohi by the Māori people, but the evidence for this identification is disputed.
