andromeda galaxy meaning in tamil

M31. Based on current evidence, it appears that M32 underwent a close encounter with the Andromeda Galaxy in the past. [26] In 1850, William Parsons, 3rd Earl of Rosse made the first drawing of Andromeda's spiral structure. [109] M110 does contain a dusty lane, which may indicate recent or ongoing star formation. ‘The lower smudge of light is from the nucleus at the centre of the Andromeda galaxy.’ ‘The patent illustrations are similarly greatly improved, beautiful, with clear lines, and missing the distracting streaks and smudges which are so often found on patent images.’ Searching the photographic record, 11 more novae were discovered. [24] Pierre Louis Maupertuis conjectured in 1745 that the blurry spot was an island universe. Until 2018, mass estimates for the Andromeda Galaxy's halo (including dark matter) gave a value of approximately 1.5×1012 M☉,[15] compared to 8×1011 M☉ for the Milky Way. கரைசலினூடாகச் செல்லும்படி குறித்தநேரத்திற்கு ஒளி படவைத்து எடுக்கப்பட்டவை. தூரத்தை அளப்பதற்கு வென்டி ஃப்ரீட்மன் என்ற வானியலாளரும் மற்றவர்களும் ஹபிள் விண்வெளி தொலைநோக்கியை சமீபத்தில் பயன்படுத்தினர்; விரிந்துகொண்டு செல்வதாகவும், அதன் காரணமாக அதன் வயது குறைவானது என்றும் அந்த அளவு உணர்த்துகிறது. Simulations of galaxies indicate the halo formed at the same time as the Andromeda Galaxy. This collision stripped more than half the mass from the smaller M32 and created the ring structures in Andromeda. Definition of andromeda galaxy in the Definitions.net dictionary. Tamil Nadu is also leading when it comes to agriculture and industrial sector . [95] The Swift BAT all-sky survey successfully detected hard X-rays coming from a region centered 6 arcseconds away from the galaxy center. Astronomers Nab Culprit in Galactic Hit-and-Run", Harvard-Smithsonian Center for Astrophysics, "Planetary camera observations of the double nucleus of M31", "Hubble Space Telescope Finds a Double Nucleus in the Andromeda Galaxy", "The Andromeda Galaxy has a Double Nucleus", "Andromeda Galaxy Scanned with High-Energy X-ray Vision", "Microquasar in Andromeda Galaxy Amazes Astronomers", "Hubble Spies Globular Cluster in Neighboring Galaxy", "The Not So Extraordinary Globular Cluster 037-B327 in M31", "Intermediate age clusters in the field containing M31 and M32 stars", "The Anomaly in the Candidate Microlensing Event PA-99-N2", "Andromeda on collision course with the Milky Way", "Apart from Andromeda, are any other galaxies moving towards us? [citation needed], The number of stars contained in the Andromeda Galaxy is estimated at one trillion (1×1012), or roughly twice the number estimated for the Milky Way. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. [28], In 1888, Isaac Roberts took one of the first photographs of Andromeda, which was still commonly thought to be a nebula within our galaxy. As a last name Messier was the 7,532 nd most popular name in 2010.; How unique is the name Messier? He believed Andromeda to be the nearest of all the "great nebulae", and based on the color and magnitude of the nebula, he incorrectly guessed that it was no more than 2,000 times the distance of Sirius, or roughly 18,000 ly (5.5 kpc). [122] An amateur telescope can reveal Andromeda's disk, some of its brightest globular clusters, dark dust lanes and the large star cloud NGC 206. Out of 6,028,151 records in the U.S. Social Security Administration public data, the first name Messier was not present. combined with preliminary reports on a 2019 study estimating a higher mass of the Milky Way. [98] மண்டலத்தில் மாத்திரமே 10,000 கோடிக்கும் அதிகமான நட்சத்திரங்கள் இருப்பதாக வானாராய்ச்சியாளர்கள் கணக்கிடுகின்றனர். The nearly invisible halo stretches about a million light-years from its host galaxy, halfway to our Milky Way galaxy. < Back Chapter 112 Next Chapter 114 > Press to Listen to this Chapter. It is the co-existence of the long-known large ring-like feature in the gas of Messier 31, together with this newly discovered inner ring-like structure, offset from the barycenter, that suggested a nearly head-on collision with the satellite M32, a milder version of the Cartwheel encounter.[86]. [from 14th c.], (astronomy) Any of the collections of many millions of stars, galactic dust, black holes, etc. Andromeda and the Triangulum Galaxy had a very close passage 2–4 billion years ago. M32 may once have been a larger galaxy that had its stellar disk removed by M31, and underwent a sharp increase of star formation in the core region, which lasted until the relatively recent past. [110] M32 has a young stellar population as well. [15][needs update]. [72] A possible cause of such a warp could be gravitational interaction with the satellite galaxies near the Andromeda Galaxy. Information and translations of andromeda galaxy in the most comprehensive dictionary definitions resource on the web. An estimation done with the help of Spitzer Space Telescope published in 2010 suggests an absolute magnitude (in the blue) of −20.89 (that with a color index of +0.63 translates to an absolute visual magnitude of −21.52,[b] compared to −20.9 for the Milky Way), and a total luminosity in that wavelength of 3.64×1010 L☉.[68]. [49] In 2003, using the infrared surface brightness fluctuations (I-SBF) and adjusting for the new period-luminosity value and a metallicity correction of −0.2 mag dex−1 in (O/H), an estimate of 2.57 ± 0.06 million light-years (1.625×1011 ± 3.8×109 astronomical units) was derived. [original research?] [113], The Andromeda Galaxy is approaching the Milky Way at about 110 kilometres per second (68 miles per second). Meaning of triangulum galaxy. Studies of the extended halo of the Andromeda Galaxy show that it is roughly comparable to that of the Milky Way, with stars in the halo being generally "metal-poor", and increasingly so with greater distance. [89] The velocity dispersion of material around it is measured to be ≈ 160 km/s (99 mi/s). Before the galaxies merge, there is a small chance that the Solar System could be ejected from the Milky Way or join the Andromeda Galaxy. [114] It has been measured approaching relative to the Sun at around 300 km/s (190 mi/s)[1] as the Sun orbits around the center of the galaxy at a speed of approximately 225 km/s (140 mi/s). Simulations show that the smaller galaxy passed through the disk of the Andromeda Galaxy along the latter's polar axis. ஒவ்வொன்றிலும் ஆயிரக்கணக்கான, சிலசமயம் நூற்றுக் கோடிக்கணக்கான நட்சத்திரங்கள் இருக்கலாமென சொல்கிறார்கள். A sci - fi TV show that used to be good, but has become lame in the later episodes. Great Nebula in Andromeda. The rotational velocity has a maximum value of 225 km/s (140 mi/s) at 1,300 ly (82,000,000 AU) from the core, and it has its minimum possibly as low as 50 km/s (31 mi/s) at 7,000 ly (440,000,000 AU) from the core. ஒவ்வொரு பால்மண்டலத்திலும் கோடிக்கணக்கான நட்சத்திரங்களைக் கொண்ட, கோடிக்கணக்கான. However, anomalies in the event were later found. According to recent studies, the Andromeda Galaxy lies in what in the Galaxy color–magnitude diagram is known as the "green valley," a region populated by galaxies like the Milky Way in transition from the "blue cloud" (galaxies actively forming new stars) to the "red sequence" (galaxies that lack star formation). Messier 31. This has been called into question by a 2018 study that cited a lower estimate on the mass of the Andromeda Galaxy,[12] has billions upon billions of stars in it. Another massive globular cluster, named 037-B327 and discovered in 2006 as is heavily reddened by the Andromeda Galaxy's interstellar dust, was thought to be more massive than G1 and the largest cluster of the Local Group;[104] however, other studies have shown it is actually similar in properties to G1. This nomenclature was subsequently adopted for stars within the Milky Way, and elsewhere. [105], Unlike the globular clusters of the Milky Way, which show a relatively low age dispersion, Andromeda Galaxy's globular clusters have a much larger range of ages: from systems as old as the galaxy itself to much younger systems, with ages between a few hundred million years to five billion years. It is about 2.6 million light years away from us. His measurement demonstrated conclusively that this feature was not a cluster of stars and gas within our own galaxy, but an entirely separate galaxy located a significant distance from the Milky Way. The planet Venus, . [118][119][120] The galaxy is commonly located in the sky in reference to the constellations Cassiopeia and Pegasus. [80], Close examination of the inner region of the Andromeda Galaxy with the same telescope also showed a smaller dust ring that is believed to have been caused by the interaction with M32 more than 200  million years ago. Find more similar words at wordhippo.com! [87] The stars in the extended halos of the Andromeda Galaxy and the Milky Way may extend nearly one third the distance separating the two galaxies. As a result, he was able to come up with a distance estimate of 500,000 ly (3.2×1010 AU). [56][57][58], In addition to stars, Andromeda Galaxy's interstellar medium contains at least 7.2×109 M☉[59] in the form of neutral hydrogen, at least 3.4×108 M☉ as molecular hydrogen (within its innermost 10 kiloparsecs), and 5.4×107 M☉ of dust. See more. [from 19th c.], The Milky Way; the apparent band of concentrated stars which appears in the night sky over earth. [32], In 1920, the Great Debate between Harlow Shapley and Curtis took place concerning the nature of the Milky Way, spiral nebulae, and the dimensions of the universe. [102] It contains several million stars, and is about twice as luminous as Omega Centauri, the brightest known globular cluster in the Milky Way. In 1991, the Hubble Space Telescope was used to image Andromeda Galaxy's inner nucleus. [37], In 1950, radio emission from the Andromeda Galaxy was detected by Hanbury Brown and Cyril Hazard at Jodrell Bank Observatory. What does Great Nebula in Andromeda mean? A 2004 Cepheid variable method estimated the distance to be 2.51 ± 0.13 million light-years (770 ± 40 kpc). Those arms, however, are not continuous and have a segmented structure. This possible exoplanet would have a mass 6.34 times that of Jupiter. Large numbers of OB associations, HII regions, and little dust. [35], In 1943, Walter Baade was the first person to resolve stars in the central region of the Andromeda Galaxy. Gale, storm, tempest, ''com monly,'' . This contradicted earlier measurements that seemed to indicate that the Andromeda Galaxy and Milky Way are almost equal in mass. To support his claim of the Great Andromeda Nebula being, in fact, an external galaxy, Curtis also noted the appearance of dark lanes within Andromeda which resembled the dust clouds in our own galaxy, as well as historical observations of Andromeda Galaxy's significant Doppler shift. Analysis of the cross-sectional shape of the galaxy appears to demonstrate a pronounced, S-shaped warp, rather than just a flat disk. This makes the Andromeda Galaxy one of about 100 observable blueshifted galaxies. Spiral galaxy in which the Solar System is located. [91], Apparently, by late 1968, no X-rays had been detected from the Andromeda Galaxy. The emission above 25 keV was later found to be originating from a single source named 3XMM J004232.1+411314, and identified as a binary system where a compact object (a neutron star or a black hole) accretes matter from a star. Information and translations of Great Nebula in Andromeda in the most comprehensive dictionary definitions resource on the web. This violent collision formed most of the galaxy's (metal-rich) galactic halo and extended disk. Andromeda is best seen during autumn nights in the Northern Hemisphere when it passes high overhead, reaching its highest point around midnight in October, and two hours later each successive month. The Andromeda Galaxy (IPA: /ænˈdrɒmɪdə/), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula (see below), is a barred spiral galaxy approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest major galaxy to the Milky Way. The nucleus consists of two concentrations separated by 1.5 pc (4.9 ly). Etymology: From the Άνδρομέδη meaning "mindful of her husband", from ανδρος (andros) "man" + medesthai, (to be mindful of, think on), related to medea, (counsels or cunning). Binoculars can reveal some larger structures of the galaxy and its two brightest satellite galaxies, M32 and M110. A likely outcome of the collision is that the galaxies will merge to form a giant elliptical galaxy[116] or perhaps even a large disc galaxy. By using our services, you agree to our use of cookies. The distances between the stars are, therefore, much greater within the newly discovered extended clusters. The dimmer concentration, P2, falls at the true center of the galaxy and contains a black hole measured at 3–5 × 107 M☉ in 1993,[88] and at 1.1–2.3 × 108 M☉ in 2005. The Galaxy M33 could be responsible for some warp in Andromeda's arms, though more precise distances and radial velocities are required. One of the explanations for this is the gravitational lensing of a red giant by a star with a mass between 0.02 and 3.6 times that of the Sun, which suggested that the star is likely orbited by a planet. - Space Facts – Astronomy, the Solar System & Outer Space - All About Space Magazine", "When Our Galaxy Smashes Into Andromeda, What Happens to the Sun? Andromeda. existing as independent and coherent systems, of which there are billions in the known universe. A galactic merger roughly 100 million years ago is believed to be responsible for a counter-rotating disk of gas found in the center of Andromeda as well as the presence there of a relatively young (100 million years old) stellar population.[45]. A cloud, . நூறு கோடிக்கணக்கான நட்சத்திர மண்டலங்கள் இருப்பதாக இப்போது விஞ்ஞானிகள் கணக்கிட்டிருக்கிறார்கள்; அந்த. [54][clarification needed] The estimated luminosity of Andromeda Galaxy, ~2.6×1010 L☉, is about 25% higher than that of our own galaxy. are so sharp that one scientist said of the repair job: “A small change for a mirror, a giant leap for astronomy.”, உடுமண்டலங்களைக் குறித்து HST அனுப்புகிற படங்கள் அவ்வளவு தெளிவாக இருப்பதால், செய்யப்பட்ட பழுதுபார்ப்பு வேலையைப்பற்றி ஒரு அறிவியலாளர் இவ்வாறு சொன்னார்: “ஆடியில் ஒரு சிறிய மாற்றம், வானவியலுக்கு ஒரு மிகப் பெரிய அடியெடுப்பு.”, And it is estimated that there are billions of. 2) Because the planet earth was in a higher cultular level, from a previous colonization by the center of local galaxy in cooperation of the central galaxy Andromeda and the rest 11 galaxies of the local group of galaxies “KNOZ”, the new collonizers from “Levan” and “Lilith” … , the Milky Way, reports The New York Times. [42] The total magnetic field has a strength of about 0.5 nT, of which 0.3 nT are ordered. to be expanding in all directions, with distant. In 1885, a supernova (known as S Andromedae) was seen in Andromeda, the first and so far only one observed in that galaxy. The Andromeda Galaxy is the nearest spiral galaxy to the Milky Way, our galaxy. Astrophysicists recently discovered what appears to be a 3,500-light-year-long plume of antimatter streaming out of the core of our. [40] The core of the Andromeda Galaxy is called 2C 56 in the 2C radio astronomy catalog. astronomers and physicists are learning ever more about our solar system, the stars, even distant, மற்றொரு திசையில் தேடுபவர்களாய், வானவியல் நிபுணர்களும் இயற்பியல் நிபுணர்களும் நம்முடைய சூரிய மண்டலம், நட்சத்திரங்கள் மேலும் தொலைவான. 2. The Andromeda Galaxy (IPA: / æ n ˈ d r ɒ m ɪ d ə /), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula (see below), is a barred spiral galaxy approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest major galaxy to the Milky Way. [108], M110 also appears to be interacting with the Andromeda Galaxy, and astronomers have found in the halo of the latter a stream of metal-rich stars that appear to have been stripped from these satellite galaxies. [54] The radio results (similar mass to Milky Way galaxy) should be taken as likeliest as of 2018, although clearly this matter is still under active investigation by a number of research groups worldwide. [50] [31], In 1917, Heber Curtis observed a nova within Andromeda. Roberts mistook Andromeda and similar spiral nebulae as solar systems being formed. It was discovered through data collected by the European Space Agency's XMM-Newton probe and was subsequently observed by NASA's Swift Gamma-Ray Burst Mission and Chandra X-Ray Observatory, the Very Large Array, and the Very Long Baseline Array. It was Phineus, he who had been betrothed to andromeda, yet who had not dared to strike a blow for her rescue. The brighter concentration, designated as P1, is offset from the center of the galaxy. , Ferris explains that the photos of faint distant objects, such as, or most nebula, “are time exposures obtained by aiming a telescope at a, and exposing a photographic plate for as long as several hours while starlight, அல்லது பெரும்பாலான ஒண்முகிற் படலங்கள் போன்ற மங்கிய தொலை தூரத்துப் பொருட்களின் நிழற்படங்கள், “ஒரு தொலைநோக்கியை ஒரு, நோக்கி இலக்காக வைத்து, ஒரு ஒளிப்படத் தட்டில் பல மணிநேரங்களுக்கு ஒளி படவைத்து, விண்மீன் ஒளி ஒளிப்படப் பால்மக். மண்டலத்தில் மட்டுமே 40,000 கோடி நட்சத்திரங்கள் இருப்பதாக விஞ்ஞானிகள் நம்புகிறார்கள். Half of the gdp comes from South Indian states like Kerala , Karnataka and Tamil Nadu. grouped into clusters and superclusters, creation reflects organization. As a result, some consider G1 to be the remnant core of a dwarf galaxy that was consumed by Andromeda in the distant past. [96], Multiple X-ray sources have since been detected in the Andromeda Galaxy, using observations from the European Space Agency's (ESA) XMM-Newton orbiting observatory. The galaxy is inclined an estimated 77° relative to Earth (where an angle of 90° would be viewed directly from the side). For the first time, he was able to resolve individual stars in the Andromeda Galaxy. [1][79], The most likely cause of the distortions of the spiral pattern is thought to be interaction with galaxy satellites M32 and M110. Data from Chandra have been used to discover 26 black hole candidates in the Milky Way's galactic neighbor, Andromeda. At the time Andromeda was considered to be a nearby object, so the cause was thought to be a much less luminous and unrelated event called a nova, and was named accordingly; "Nova 1885". Meaning of Great Nebula in Andromeda. Gust, squall, . The A stars are not evident in redder filters, but in blue and ultraviolet light they dominate the nucleus, causing P2 to appear more prominent than P1. [81], In 1998, images from the European Space Agency's Infrared Space Observatory demonstrated that the overall form of the Andromeda Galaxy may be transitioning into a ring galaxy. The total mass of the galaxy increases linearly out to 45,000 ly (2.8×109 AU), then more slowly beyond that radius.[73]. [101] The most massive of these clusters, identified as Mayall II, nicknamed Globular One, has a greater luminosity than any other known globular cluster in the Local Group of galaxies. This page provides all possible translations of the word andrology in the Tamil language. existing as independent and coherent systems, of which there are billions in the known universe. In simulated galaxies with similar properties to Andromeda Galaxy, star formation is expected to extinguish within about five billion years from the now, even accounting for the expected, short-term increase in the rate of star formation due to the collision between Andromeda Galaxy and the Milky Way. Milky Way has billons of stars. [27] The spectra of Andromeda displays a continuum of frequencies, superimposed with dark absorption lines that help identify the chemical composition of an object. [4] The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda, which itself is named after the Ethiopian (or Phoenician) princess who was the wife of Perseus in Greek mythology. Applying trigonometry (angular diameter), this is equivalent to an apparent 4.96° angle in the sky. This may indicate a common tidal origin for the satellites. மண்டலத்தில் மட்டும் சுமார் 100 வட்டவடிவ கொத்துகள் உள்ளன. [23] There are about 100 known globular clusters in our Milky Way. [97] An observation campaign of NuSTAR space mission identified 40 objects of this kind in the galaxy. The rate of star formation in the Milky Way is much higher, with Andromeda Galaxy producing only about one solar mass per year compared to 3–5 solar masses for the Milky Way. The Great Sage AGATHIYAR, Being the DUTIFUL ENLIGHTENED TEACHER OF UNIVERSAL WISDOM’ [BRAHMANDA GURU AVATAR] Upon this PLANET EARTH, Incarnated having the UNIVERSAL GRACE of Both SUPREME LORDS ‘MAHESHVARA’ [DAKSHINA MURTHI, SADA SHIVA] and ‘ISHVARA’ … 1. In a large telescope it creates a visual impression of a star embedded in the more diffuse surrounding bulge. [a] And, from this, the diameter of Andromeda at the widest point is estimated to be 220 ± 3 kly (67,450 ± 920 pc). [90], It has been proposed that the observed double nucleus could be explained if P1 is the projection of a disk of stars in an eccentric orbit around the central black hole. He added that it was “expected to observe distant stars and, with a clarity 10 times that ever before achieved.”. [80] This can be seen by the displacement of the neutral hydrogen clouds from the stars. These interactions have formed structures like Andromeda's Giant Stellar Stream. Are these beings from the Andromeda galaxy (2.57 million light years away) or from the stars 42 (φ Andromedae at 736 light years) and 44 Andromedae (174 light years away)? Only six other stars of this type have been detected in our, இதுபோன்ற வெறும் ஆறு நட்சத்திரங்கள் மட்டுமே நம் ஆகாய, Milky Way, which is about 100,000 light-years across, is only one of billions of, அண்டத்தைப் பற்றி வாசிக்கையில், சுமார் 1,00,000 ஒளி ஆண்டுகள் தூரத்திலுள்ள பால்வீதி மண்டலம், விண்வெளியிலுள்ள கோடிக்கணக்கான. [83] This ring is hidden from visible light images of the galaxy because it is composed primarily of cold dust, and most of the star formation that is taking place in the Andromeda Galaxy is concentrated there. What distinguishes them from the globular clusters is that they are much larger—several hundred light-years across—and hundreds of times less dense. A spiral galaxy in the Local Group and closest to the Milky Way, visible to the naked eye in the constellation of Andromeda, the brightest of the Messier objects and often referred to by its designation M31. The velocities slowly decline beyond that distance, dropping to around 200 km/s (120 mi/s) at 80,000 ly (5.1×109 AU). Previously, estimates of the Andromeda Galaxy's size ranged from 70,000 to 120,000 light-years (21 to 37 kpc) across. Synonyms for androgynous include bisexual, epicene, genderless, hermaphrodite, unisex, unisexual, ambisexual, androgyne, cross-sexual and hermaphroditic. Spectroscopic studies have provided detailed measurements of the rotational velocity of the Andromeda Galaxy as a function of radial distance from the core. Compared to the Milky Way, the Andromeda Galaxy appears to have predominantly older stars with ages >7×109 years. Aug 29, 2014 - --> We Bring You Makar Rashi Baby Boy Names With Accurate Meanings. 2. As per N6/S6 but fainter and inconspicuous. The Milky Way and Andromeda galaxies are expected to collide in around 4.5 billion years,[16][17] merging to form a giant elliptical galaxy[18] or a large lenticular galaxy. ஒன்றே ஒன்று என்பதை நீங்கள் கற்றுக்கொள்ளலாம். பால்வீதி மண்டலத்தின் மையப்பகுதியிலிருந்து வெளிவரும், 3,500 ஒளியாண்டு நீளமான எதிர்ப்பொருளின் வால்போன்ற புகைமண்டலமாக இருக்கலாமென தோன்றுவதை வான்-இயற்பியலாளர்கள் சமீபத்தில் கண்டுபிடித்தனர் என த நியூ யார்க் டைம்ஸ் அறிவிக்கிறது. [84], Later studies with the help of the Spitzer Space Telescope showed how Andromeda Galaxy's spiral structure in the infrared appears to be composed of two spiral arms that emerge from a central bar and continue beyond the large ring mentioned above. [94] A balloon flight on 20 October 1970, set an upper limit for detectable hard X-rays from the Andromeda Galaxy. அதன் விளைவாக, ஆயிரக்கணக்கான குறுங்கோள்கள், நட்சத்திரங்கள், பால்மண்டலங்கள், நெபுலாக்கள் ஆகியவற்றைத்தான் கண்டுபிடித்தனரே தவிர ஒரு புதிய கிரகம்கூட அகப்படவில்லை. In 1864 Sir William Huggins noted that the spectrum of Andromeda differed from that of a gaseous nebula. In 2005, astronomers used the Keck telescopes to show that the tenuous sprinkle of stars extending outward from the galaxy is actually part of the main disk itself. India without Tamil Nadu will be a really bad image I would say . [69] This suggests that the latter once experienced a great star formation phase, but is now in a relative state of quiescence, whereas the Milky Way is experiencing more active star formation. alone may contain up to 400 billion stars. It can be seen from the Northern Hemisphere in May with a telescope or binoculars, sitting between the constellations Virgo and Leo, according to NASA.

[1] However, infrared data from the 2MASS survey and from the Spitzer Space Telescope showed that Andromeda is actually a barred spiral galaxy, like the Milky Way, with Andromeda's bar major axis oriented 55 degrees anti-clockwise from the disc major axis.[71]. Synonyms for Great Nebula in Andromeda include Andromeda Galaxy, M31, NGC 224, Andromeda, Messier 31 and UGC 454. [5] Averaged together, these distance estimates give a value of 2.54×10^6 ± 0.11×10^6 ly (1.606×1011 ± 7.0×109 AU). மண்டலத்திலிருந்து சின்னஞ்சிறு அணுக்கள் வரை, அவருடைய ஞானத்தையும் வல்லமையையும் நம்மை சுற்றியுள்ள உலகமும் பிரபஞ்சமும் பறைசாற்றுகிறது. ± 0.13 million light-years ( 770 ± 40 kpc ) across these heavier elements into space and Share.!, சிலசமயம் நூற்றுக் கோடிக்கணக்கான நட்சத்திரங்கள் இருக்கலாமென சொல்கிறார்கள் of kelvins and emitting X-rays and compact star cluster at its very....
