Stephan’s Quintet is a group of five galaxies, NGC 7317-7320, first discovered by the French astronomer Édouard Stephan at Marseilles Observatory in 1877. The star’s spectrum shows an overabundance of barium and strontium. It is 9,000 light-years away from us, and it has an apparent magnitude of 9.4. Pegasus is visible in both the Northern and Southern hemispheres. There is only one meteor shower associated with the constellation of Pegasus, the July Pegasids. The lensing effect is a result of spacetime around massive objects such as black holes or galaxy clusters being curved, which allows rays of light from a source located in the background to be bent. The Great Square of Pegasus asterism is used by astronomers as a guide towards finding famous deep-sky objects, such as the Andromeda Galaxy. It has an apparent magnitude of 13.8, and it was discovered since 1872 by Edouard Stephan. The exoplanet orbiting 51 Pegasi, is designated as 61 Pegasi b, and it is known as Dimidium. It has an apparent magnitude of 4.40. It has an apparent magnitude of 3.514. The most famous myth involving Pegasus is the one of Bellerophon, the hero who was sent by King Iobates of Lycia to kill the Chimaera, a monster that breathed fire and was devastating the king’s land. It has around 217% of our Sun’s mass, 597% of its radius, and it is 43.2 times brighter than our Sun. With an absolute magnitude of -9.2, M15 is 360,000 times brighter than the Sun. The quasar is called the Einstein Cross because as many as four images of the quasar appear around the galaxy in the foreground as a result of strong gravitational lensing. Algenib is also the most distant star from this asterism, located at around 390 light-years away from us, being situated in the southeast corner of the asterism. The star, HD 209458, is only 14% more massive, and 20% bigger than our Sun. This galaxy’s arms, dust, and gas have been highly disturbed due to the interaction of the other galaxies which are members of the Quintet. The star has a radius 24% larger than the Sun and is 11% more massive. NGC 7320 is a spiral galaxy 39 million light years distant. The constellation of Pegasus is located in the northern celestial hemisphere. This star is located at around 690 light-years away from us. It is classified as a Seyfert galaxy undergoing star forming activity in the core and outer spiral arms. Apart from the aforementioned Messier 15 globular cluster, some other deeps-sky objects that reside in the constellation of Pegasus are the spiral galaxy NGC 7331, the Seyfert galaxy NGC 7742, the quasar nicknamed as Einstein’s Cross, the Stephan’s Quintet – which is a cluster of galaxies, NGC 7725 and NGC 7753, which are a pair of colliding galaxies, the unbarred spiral galaxies NGC 7217, and NGC 742, the elliptical galaxy NGC 7315, or another pair of colliding galaxies, NGC 7318a and NGC 7318b, among many other objects. Pegasus (Greek Pegasos) is the winged white horse, son of Poseidon in the shape of a horse.At birth Pegasus sprang forth from the bloody neck of the Gorgon Medusa when she was beheaded by the hero Perseus.A spring was created when Pegasus' hooves struck the earth on Mount Helicon, the fabled spring of Hippocrene, at the behest of Poseidon to prevent the mountain swelling too much. HR 8799 is the only known star to be classified as a Gamma Doradus variable, a Lambda Bootis, and Vega-like star. The subdwarf star has only 60% of our Sun’s mass, 8% of its radius, and it is around 400 times brighter, with temperatures reaching 10,000 K. The red giant star has around 250% of our Sun’s mass, 8,500% of its radius, and it is 1,150 times brighter than our Sun. Everyone knows about the constellations, but very few know about their importance. The brightest star in the constellation is Enif, Epsilon Pegasi, with an apparent magnitude of 2.399. The brightest stars in the cluster are of magnitude 12.6. Curiously, the constellation Pegasus only represents the top half of the horse. HR 8799 is classified as a Lambda Bootis star – it has its surface layers depleted in iron peak elements. Pegasus was born when the legendary Greek hero Perseus, cut off Medusa’s head, who was impregnated by the god Poseidon. This galaxy was discovered by William Hershel in 1784. The flying horse Pegasus, who was born from the stump of Medusa's neck after Perseus had decapitated her. Alkarab, designated as Upsilon Pegasi, is an F-type yellow-white aging giant star, located at around 170 light-years away from us. Pegasus is one of the 48 constellations listed by the Greek astronomer Ptolemy in the second century. When the primary star will evolve into a red giant, it is expected to grow to a point where the secondary star can accrete matter from the expanded gaseous envelope. Image: NASA, ESA, and STScI. Pegasus created a spring by striking the ground with his hoof. The giant is however cooler than our Sun, having temperatures of around 3,650 K. Phi Pegasi and Psi Pegasi are pulsating red giant stars located at around 460 light-years, and 480 light-years respectively. It is 12 times more massive than the Sun, about 5000 times more luminous, and it has 185 times the Sun’s radius. Greek name: Ἵππος (Hippos) Pegasus was the winged horse best known for his association with the Greek hero Bellerophon. It is among the oldest globular clusters, with an estimated age of around 12.0 billion years. Astronomers think that the radio jet in NGC 7479 was put into its bizarre backwards spin following a merger with another galaxy. The name, however, is a bit of a misnomer. Four of the five galaxies were the first compact galaxy group ever discovered. The galaxy is also notable for a number of stars that rotate in the opposite direction to the majority around the galaxy’s core, and for having two quite distinct groups of stars, the young, metal-poor population on the outermost regions and stars of intermediate age on the innermost ones. NGC 7217 is an unbarred spiral galaxy with an apparent magnitude of 11.0. Algenib is the largest and most massive star of the Great Square asterism. The constellation of Pegasus is bordered by the constellations of Andromeda, Aquarius, Cygnus, Delphinus, Equuleus, Lacerta, Pisces, and Vulpecula. NGC 7725 and NGC 7753 are a pair of interacting galaxies, with one of them being a barred spiral galaxy – NGC 7725, and the other a satellite barred lenticular galaxy – NGC 7753. The galaxy is notable for having a ring, but no bar, which would normally produce the ring structure in the galaxy. NGC 7814 is a spiral galaxy in Pegasus seen edge-on. It is about 1500 times more luminous than the Sun. NGC 7742 is an unbarred spiral galaxy in Pegasus, seen face-on. The constellation Pegasus is one of seven constellations in the sky that tell why it is not good to say that a mortal is more beautiful than the gods. The July Pegasids occur between the 7 and 13 of July. It has a visual magnitude of 13.2 and a diameter of 2.2 arc minutes. It was first catalogued by the Greek astronomer Ptolemy in the 2nd century. Pegasus is the 7th largest constellation in the sky, stretching for around 1211 square degrees. NGC 7320 has large H II regions where intense star formation is taking place. It has an apparent magnitude of 11.6 and is approximately 40 million light years distant. It has a visual magnitude of 2.84 and is approximately 390 light years distant. NGC 7479 is a barred spiral galaxy. Pease 1 was the first planetary nebula discovered within a globular cluster. Zeus eventually placed Perseus among the constellations. The Story of Perseus Take a look at the story of how Perseus slew Medusa, the mother of Pegasus, and rescued Andromeda, the daughter of Cepheus and Cassiopeia, from the sea monster Cetus. It has an apparent magnitude of 2.399, and it is also an LC slow irregular variable star that varies from +0.7 to +3.5 in magnitude. In ancient Persia, Pegasus was depicted by al-Sufi as a complete horse facing east, unlike most other uranographers, who had depicted Pegasus as half of a horse, rising out of the ocean. He was born together with Chrysaor from Medusa’s blood. The galaxy is not part of the Hickson Compact Group, but is located in the same line of sight as the other four galaxies. The Myth Behind the Constelltion Pegasus. It has a visual magnitude of 2.95 and is the fifth brightest star in the constellation. Monocular vs. Binoculars- Which One is Best for Stargazing, The constellation of Pegasus was among the first 48 Greek constellations, first listed by the famous astronomer Ptolemy, in his 2, Pegasus is now among the 88 modern constellations, where it holds the title of the 7. Pegasus contains only one Messier object, the globular cluster Messier 15, which is located at around 33,000 light-years away from Earth. The brighter component in the system is a bright giant of the spectral type G2 II, four times more massive and 247 times more luminous than the Sun. Athena turned Medusa into a monster, that had snakes instead of hair, and her face was so abhorring that anyone who gazed at her, would turn into stone. Its main geometrical figure is the "Great Square of Pegasus." The star is also hotter, having temperatures of around 7,872 K, and it is also a fast-spinning star, with a rotational velocity of around 136 km / 84.5 mi per second. Pegasus is a magnificent constellation occupying more than 1200 square degrees in the sky. Athena turned Medusa’s hair into snakes and made her face so ugly that anyone who looked at her immediately turned to stone. The galaxy is a gas-poor system. The name Hippocrene means “the horse’s fountain.” It was said that those who drank from the spring were blessed with the gift to write poetry. It has an apparent magnitude of 10.4. In literature and theater The constellation of Perseus is depicted with only the top half of the horse. The name Pegasus is of Greek origin, derived from the word “pegai” which means “springs” or “waters”, and Chrysaor’s name means “the golden sword”. It has only 50% of Jupiter’s mass, and it is very close to its parent star, experiencing temperatures of around 1200o C. IK Pegasi, designated as HD 8210, is a binary star system located at around 154 light-years away from us. Baham has around 214% of our Sun’s mass, 262% of its radius, and it is 23.7 times brighter than our Sun. The radiant of the Pegasids appears to come from around 5 degrees west of the star Markab / Alpha Pegasi. NGC 7331 is the brightest galaxy in the NGC 7331 Group, sometimes also called the Deer Lick Group. The constellation is known for the Great Square of Pegasus, a familiar asterism in the northern sky, as well as for a number of bright stars and deep sky objects, among them Messier 15 (NGC 7078, Cumulo de Pegaso), Stephan’s Quintet of galaxies, the Einstein Cross (a gravitationally lensed quasar), and the unbarred spiral galaxy NGC 7742. Pegasus is the seventh largest constellation in the sky, occupying an area of 1121 square degrees. Homam, designated as Zeta Pegasi, is a bright star located at around 204 light-years away from our Solar System. Despite this success, Bellerophon asked Pegasus to take him to Mount Olympus, after his children had died. The galaxy is notable because a Type Ia supernova, SN 2007B, was observed in it in 2007. The star is losing mass and as a result it has a shell of gas and dust that is expanding with a radius of about 3500 times that of the Sun. She had snakes for hair and hated everyone, including her son, Pegasus. The world of constellations. The constellation of Pegasus is named and associated after the legendary winged horse, also named Pegasus, from Greek mythology. NGC 7331 is the brightest member of the NGC 7331 Group of galaxies. It is 25 times more luminous than the Sun and has 2.6 times the solar radius. Pegasus constellation lies in the northern hemisphere. Pegasus is a prominent constellation in the northern sky, named after a winged horse in Greek mythology. This is the hunt if finding the story and meaning of Pegasus constellation. The Andromeda Galaxy, also designated as Messier 31, can be found between the Great Square and Cassiopeia’s W asterism. However, too many quasars have been discovered that were closely associated with galaxies significantly less distant than that. It has an apparent magnitude of 2.48 and is approximately 133 light years distant. The constellation contains 15 formally named stars. The Story of Pegasus Pegasus the Winged Horse has a long history with stargazers. Continuing clockwise, the next galaxy appears to have two cores, but it is actually two galaxies, NGC 7318A and NGC 7318B. The Triangulum Galaxy, designate as Messier 33, can be found in the opposite direction of the Andromeda Galaxy. NGC 7319 is a spiral galaxy approximately 360 million light years distant. It is a starburst galaxy; one that has recently experienced intense star forming activity. In Greek mythology, Pegasus represents a flying horse flown by Bellerophon. This star is 530 million years old, and it is still hotter than our Sun, having temperatures of around 6,300 K. The constellation of Pegasus hosts numerous interesting deep-sky objects. The cluster was discovered by the Italian-born astronomer Jean-Dominique Maraldi in 1746, and included in Charles Messier’s catalogue in 1764. The constellation was named after Pegasus, the winged horse in Greek mythology. The magnitude 9 star, AG Pegasi, is classified as a symbiotic nova, having undergone one extremely slow nova outburst in 1885, when it reached magnitude 6, and a smaller outburst. It is also older than the Sun, with an estimated age between 6.1 and 8.1 billion years. In some depictions, the horse is shown rising out of the water. Encircling the galaxies are young, bright blue star clusters and pinkish clouds of glowing hydrogen where infant stars are being born. It has an apparent magnitude of 11.0, and it is a gas-poor system. Take an interactive tour of the solar system, or browse the site to find fascinating information, facts, and data about our planets, the solar system, and beyond. The resulting stream which flowed from the spot he had pawed became sacred to the Muses. It is a fast-spinning star, having a rotational velocity of 135 km / 83.8 mi per second. Scheat is a red giant star, located in the upper right corner of the asterism. Alpha Pegasi is giant star belonging to the spectral class B9 III. Its traditional name, Enif, comes from the Arabic word for “the nose.” The star marks Pegasus’ muzzle. Pegasus was a flying horse. Its projected Galactic orbit carries it between 18,600 and 26,300 light-years from the center of our galaxy. NGC 7317, at bottom left, is a normal-looking elliptical galaxy that is less affected by the interactions. It belongs to the spectral class G5V and has an apparent magnitude of 5.49.

It is classified as a Delta Scuti variable and its variation cycle repeats itself 22.9 times a day. Salm has around 214% of our Sun’s mass, 280% of its radius, and it is 32 times brighter. The star is also classified as a Gamma Doradus variable – its luminosity changes due to non-radial pulsations on its surface, and it is also a Vega-like star – having excess infrared emission caused by a circumstellar disk. He served as Perseus’ steed and helped the hero defeat the sea-monster Cetus to save Princess Andromeda and the country of Aethiopia. How to choose your telescope magnification? However, at radio wavelengths, this galaxy, sometimes nicknamed the Propeller Galaxy, spins the other way, with a jet of radiation that bends in the opposite direction to the stars and dust in the arms of the galaxy. When the white dwarf will approach its limit, it may explode as a Type la supernova. But he didnt do it by himself: he had a lot of help from Athena. It contains more than 100,000 stars, among them a significant number of variables and pulsars, including the double neutron star M15 C. The cluster is also home to Pease 1, a planetary nebula discovered in 1928. These interactions have sparked a frenzy of star birth in the central pair of galaxies. The Propeller Galaxy, designated as NGC 7479, or Caldwell 44, is an unbarred spiral galaxy located at around 105 million light-years away from us. It was a fool’s errand, as the king hoped Perseus would die, since he wished to enslave Perseus’s mother. It has several rings of stars of which the outermost is most prominent and contains most of the gas and star forming activity in NGC 7217. Pegasus managed to reach Olympus, where the supreme Greek god Zeus used the horse to carry his thunder and lightning. it is classified as a type E4 elliptical galaxy. Coordinates have shifted since and this is no longer the case. Pegasus is the seventh largest constellation, taking up nearly 1,200 square degrees of space in the night sky, and can be seen by observers located between +90° and -60° of latitude. When the catalogue was compiled, objects were arranged by right ascension, and NGC 1 had the lowest right ascension at the time (00h07m15.86s). Ptolemy was an ancient astronomer who named and recorded the first 48 constellations, including Pegasus, the winged horse. The name Pegasus is derived from the Greek pegai which means “springs” or “waters,” and Chrysaor’s name means “the golden sword.”. There is only one Messier object located in the constellation of Perseus, the globular cluster Messier 15, also known as NGC 7078, or Cumulo de Pegaso. Beta Pegasi has an apparent magnitude of 2.42 and is about 196 light years distant. After this and several other heroic deeds for King Iobates, Bellerophon let the successes get to his head. The brightest star in Pegasus is Enif / Epsilon Pegasi, which has an apparent magnitude of 2.399. Pegasus is a conspicuous constellation which includes the so-called "Great Square of Pegasus". Hippocrene was one such spring, and it was blessed, so much so, that those who drank from its water, were given the ability to write poetry. The galaxy was discovered by the German-born British astronomer William Herschel in 1784. The brightest galaxy in the group is NGC 7320, which is only 40 million light years distant. Pegasus belongs to the Perseus family of constellations, along with Andromeda, Auriga, Cassiopeia, Cepheus, Cetus, Lacerta, Perseus, and Triangulum. 1. NGC 7319 has an apparent magnitude of 14.1.

It has an apparent magnitude of 6.2 and is about 33,600 light years distant. NGC 7318, designated as UGC 12099 / UGC 12100, are a pair of colliding galaxies located at around 300 million light-years away from us. Eta Pegasi is a double star approximately 167 light years distant from the solar system. Pegasus is part of the Perseus family of constellations, along with Andromeda, Auriga, Cassiopeia, Cepheus, Cetus, Lacerta, Perseus, and Triangulum. Pegasus contains a Messier object – Messier 15 (NGC 7078, Cumulo de Pegaso) – and has nine stars with confirmed planets. Studies have shown that group member NGC 7320, at upper left, is actually a foreground galaxy about seven times closer to Earth than the rest of the group.Three of the galaxies have distorted shapes, elongated spiral arms, and long, gaseous tidal tails containing myriad star clusters, proof of their close encounters. Messier 15 – This globular lies about 35 000 light-years from the Earth, in the constellation of Pegasus (The Flying Horse). This star is a semi-regular variable type of star, having brightness variations between magnitude 2.31 and 2.74 within a period of 43.3 days. It has a combined apparent magnitude of 6.08. Enif, designated as Epsilon Pegasi, is the brightest star in the constellation of Pegasus. The exoplanet, 51 Pegasi b, was discovered on October 6, 1995. The planet was nicknamed Bellerophon. It is 3,885 times brighter than our Sun, while its bolometric luminosity is 12,250 times greater. It has four times the solar radius. In the 17th century, Johann Bayer gave the star a dual designation, Alpha Andromedae and Delta Pegasi. Pi1 Pegasi has 248% of our Sun’s mass, 1,100% of its radius, and it is 62.8 times brighter while being only 530 million years old. Perseus was sent to kill Medusa by King Polydectes of Seriphus, who was the brother of Dictys, the man who took Perseus and his mother Danaë in and raised Perseus as his own son. Then he swooped down on the Chimaera from the sky and killed the monster with his lance and arrows. The white, winged horse Pegasus was the offspring of Poseidon and the Gorgon , Medusa, springing from the latter's neck when she was killed by Perseus. It has an apparent magnitude of 12.35. HR 8799 is a young main-sequence star located at around 129 light-years away from us. It has an apparent magnitude of 13.2. It has a radial pulsation period of 0.15175 days during which its brightness varies from 2.78 to 2.89. Most of the quintet is too far away even for Hubble to resolve individual stars. Theta Pegasi belongs to the spectral class A2 Vp and is about 67 light years distant from Earth. Pegasus was a winged horse in ancient Greek mythology . It was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and is one of the 88 constellations recognised today. Located in the northern sky, Pegasus is the 7th largest constellation in the celestial sphere. The star is 36% more luminous, it has similar temperatures, but it is older than our Sun, with an estimated age of around 6.1 billion years. Pegasus was later brought to Mount Helicon by Bellerophon and with one kick of his hoof, he caused the spring of Hippocrene to flow. NGC 1 was discovered in 1861 by Heinrich d’Arrest. Messier 15 is around 175 light-years in diameter, and it is a bright cluster, having a total luminosity of 360,000 times that of the Sun, and as such, it is among the densely packed globular clusters in our Milky Way Galaxy. NGC 1, also designated as GC 1, or UGC 57, is an intermediate spiral galaxy located at around 211 million light-years away from us. Zeta Pegasi is a rapid rotator, with an estimated rotational velocity between 140 and 210 km/s. Another famous myth associated with Pegasus is that involving another Greek hero, namely Bellerophon. Perseus, against all odds, managed to kill Medusa by cutting her head, and this is when Pegasus, and the warrior Chrysaor, sprang from her neck – both of them being the offspring of Poseidon. It has a few million years left to live, though it isn’t clear if it will explode as a supernova or die off as a rare neon-oxygen white dwarf, due to its mass straddling the dividing line between stars destined to explode or not. Sadalbari has exhausted the fuel in its core, and it has started to expand. Photo: NASA. Image: ESA, Hubble and NASA. According to the listed constellation currently, the constellation of Pegasus is the 7th largest constellation in the northern sky. The star system is composed out of a subdwarf star, and a red giant star. It has an apparent magnitude of 13.6. The constellation of Pegasus is the 7th largest constellation in the sky. NGC 7319 is a highly distorted barred spiral galaxy located at around 360 million light-years away. The traditional name, Scheat, comes from the Arabic Al Sā’id, which means “the upper arm.”. Pegasus is a seasonal constellation that is best seen in the autumn months in the northern hemisphere. The companion is a main sequence star belonging to the spectral class F0 V. The name Matar comes from the Arabic phrase Al Saʽd al Maṭar, which means “the lucky star of rain.”. After this huge success and other heroic deeds performed for King Iobates, Bellerophon began to believe he was entiltled to join the gods on Mount Olympus. There are plenty of interesting bright stars in Pegasus, among them, the brightest star Enif, the second-brightest, Scheat, the third-brightest, Markab, the fourth-brightest Algenib, the red dwarf, and white dwarf star system designated as AG Pegasi, the pulsating Phi, and Psi Pegasi red giants, the white star Salm, or the first discovered Sun-like star to host an exoplanet, 51 Pegasi, among many others.

It is also a fast-spinning star, having a rotational velocity of 140 km / 86.9 mi per second. The parent star has some unique features. It has an apparent magnitude of 11.9. Though Pegasus agreed, he plummeted back to Earth after Zeus either threw a thunderbolt at him or sent a gadfly to make Pegasus buck Bellerophon off, after which he placed Pegasus into the heavens. It has an apparent magnitude of 7.65, and it hosts an exoplanet designated as HD 209458 b. The star is also notable for having a relatively high peculiar velocity (true velocity) of 21.6 km/s. 51 Pegasi is only 11% more massive than our Sun, and its radius is only 23% greater than our Sun’s. There is a famous asterism in Pegasus, which is named the Great Square of Pegasus. The exact location of the quasar is at 22h40m30.3 (right ascension), +3°21’30.3” (declination). Perseus is the 24th largest constellation in the sky. Its brightest star is Enif (from the Arabic for “the nose”), with a magnitude of 2.4. The five galaxies that makeup Stephan’s Quintet are NGC 7317, NGC 7318a, NGC 7318b, NGC 7319, and NGC 7320c. The name of this constellation comes from Greek mythology after a … When Pegasus was born, he flew away to Mount Helicon in Boeotia, where the Muses lived, and he befriended them. To the observers on earth, the winged horse appears to be flying upside down. Enif is quite a young star, having an estimated age of around 20 million years. Pegasus sprang from the monster’s blood. It is cooler than our Sun, having temperatures of around 4,379 K, and it has a rotational velocity of 8 km / 4.97 mi per second.
