Generally, larger Stars have a shorter lifespan. The celestial pole defines the poles of the celestial equatorial coordinate system. Basically, its a group of Stars. The Constellations are continually on the move. Musc is the abbreviation for Musca from a naming convention used by NASA. The right ascension is the angular distance of any sky object along the celestial equator from the March (Spring) equinox. Where to cruise in Europe? It is visible to observer situated between +10 and -90 of latitude, but is best seen in the month of May. Musca Australis vel Indica, the Southern or Indian Fly, the French Mouche Australe ou Indienne, the German Sudliche Fliege, and the Italian Mosca Australe, lies partly in the Milky Way, south of the Cross (), and east of the Chamaeleon. [18] It is around five times as massive as the Sun. Comments may be merged or altered slightly such as if an email address is given in the main body of the comment. It is also an astronomy term used to describe a variety of groups of stars that have been given a specific name such as . Musca lies south of the Ecliptic which is different to the Celestial Equator. The constellations brightest star is Alpha Muscae, a blue-white subdwarf found 315 light years from Earth that shines with a visual magnitude of 2.69. Alpha Muscae is a main star in the constellation Musca and makes up the constellation outline. It is a blue-white star that is about 190 light years away from Earth. 42 animals, 29 objects & 17 humans / mythological characters. Stewart, Suzy. [47] The star system varies in magnitude from 10.2 to 12.7 over a period of 624.5 days. Constellation in the southern celestial hemisphere, This article is about the southern constellation. It is also known as the myth of Leo the Lion. It occupies an area 10.25 arcminutes across and has a physical diameter of about 4 light-years. The constellation name Musca is pronounced /msk/. Hipparcos created the apparent magnitude system to rank the brightness of Stars (for example he decided that that the grade of a first magnitude star should be twice as bright as a second magnitude Star, and so on. You can decline to give a name which if that is the case, the comment will be attributed to a random star. The constellation Musca, the fly, is located in the southern hemisphere of the sky. [35], Theta Muscae is a triple star system thought to be around 7,500light-years distant. The dim star has an apparent magnitude of 5.95. The cluster was discovered by Nicolas Louis de Lacaille in 1751-1752. Based on the spectral type (B2IV-V) of the star, the Alpha Muscae colour is blue . The primary star is an orange giant with the stellar classification of K2III, and the spectral type of the companion star is unknown. The average distance to the main stars is 250.22 light years. Out of the 88 constellations recognized by the International In the email will be a link to unsubscribe to further notifications. degrees of the night sky which equates to 0.34% of the night sky. A Constellation does not actually exist as a fixed object, it is a group of bright stars that happen to be in a random place and are light years apart and ever moving. Bordering the constellations of Musca are Apus, Carina, Centaurus, Chamaeleon, Circinus and Crux (the Southern Cross). It has a visual magnitude of 7.61 and is 95 light years distant from the solar system. Sometimes they can act as Star nurseries as areas where new Stars are forming. If you use any of the content on this page in your own work, please use the code below to cite this page as the source of the content. Later, in 1603, the Constellation of Musca was listed in Johann Bayers Uranometria, although he referred to it as the Constellation Apis, meaning the Bee. The two created 12 constellations during expeditions under the southern skies. The brightest star in Musca is the magnitude 2.69 Alpha Muscae, which is located 315 light-years from Earth. It is 790 times more luminous than the Sun. [64] West of Epsilon Muscae is NGC 4071, a large, diffuse planetary nebula of magnitude 12.7 with a magnitude 12 central star,[63] thought to lie around 4000 light-years away from Earth. However, in the case of the constellation of Musca there were no associated Greek myths, nor did they mention the image of a fly. [23] Alpha, Beta, Gamma, HD 103079, Zeta2 and (likely) Eta are all members of the Lower Centaurus Crux subgroup of the ScorpiusCentaurus association, a group of predominantly hot blue-white stars that share a common origin and proper motion across the galaxy. As well as Stars and Star Clusters, the Musca Constellation also has deep sky objects and galaxies (or even globular clusters or open clusters). [1] The whole constellation is visible to observers south of latitude 14N. Studying these ancient cosmic clusters can help astronomers to unravel how a galaxy formed and evolved, and give an idea of the galaxys age. This constellation was invented by Pieter Dircksz Keyser, a navigator who joined the first Dutch expedition to the East Indies in 1595 and who added 12 new constellations in the southern skies. The nearest star to the Earth with an exoplanet is HD 111232 which is about 95.71 Light Years. A nearby star of magnitude13 may or may not be a companion star. Gamma Muscae is a blue-white main sequence dwarf. the Northern Fly. Key Data Bordering Constellations: Crux is bordered by constellations Musca & Centaurus. [12] The three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is "Mus". Fact: the larger the apparent magnitude number the dimmer the Star appears. If you look up and into the Southern night sky you can imagine the outline of Musca, as a fly. There are 66 stars that can be seen with the naked eye in the constellation on a very clear night sky. Beta Mus a variable visual magnitude of 3.04, 3. [44] During the 1991 outburst which led to its discovery, radiation was produced through a process of positron annihilation. It is also a confirmed runaway star system, one moving through space with an abnormally high velocity compared to the surrounding interstellar medium. This constellation was discovered or assumed by a Dutch astronomer whose name is Petrus Plancius in. Musca is usually associated with the name the fly, but was previously called Constellation Apis, meaning the Bee. There's no register feature and no need to give an email address if you don't need to. In the equatorial coordinate system, the right ascension coordinates of these borders lie between 11h 19.3m and 13h 51.1m , while the declination coordinates are between 64.64 and 75.68. Representing a fly, it is among the twelve constellations introduced by Pieter Dirkszoon Keyser . NGC 4833 is one of the over 150 globular clusters known to reside within the Milky Way. These voyages enabled Dutch navigators and cartographers Pieter Dirkszoon Keyser and Frederick de Houtman, (students of Petrus Plancius) to make astronomical observations on their sea voyages of the bright stars and constellations in the southern sky. Crux is home 'The Jewel Box Cluster' # 3. The star constellations that can be seen in the night sky depend on the observer's location and season, and they change throughout the year. The Dutch astronomer Petrus Plancius is credited with creating and naming the 12 Constellations noted during the Dutch sea voyages to the East Indies in the 16th Century. It was Charles Messier, a French astronomer, who is credited with cataloging each of the Messier Star clusters, around 1764. It has an apparent magnitude of 3.84 and can be seen without binoculars. This constellation is made up of 604 Stars in total, although only 31 Stars are visible by the naked eye. There are 88 constellations in the sky The largest constellation is 'Hydra' The Greeks were the first to name the constellations The smallest constellation is 'Crux' [33] A luminous star around 5.9times as massive as the Sun, it is a binary star with a blue-white main-sequence star companion likely to be of spectral type B3V to B5V with a mass of just over 5solar masses,[34] one of the hottest and brightest companions of a cepheid known. We see the pattern of their presence. Musca is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. The constellation was created by the Dutch astronomer Petrus Plancius from the observations of Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman in the late 16th century. "Musca Constellation Features and Facts". Musca is a southern celestial hemispheric constellation. Edmond Halley renamed it Musca Apis, the Fly Bee. The star has an apparent magnitude of 2.69 and is approximately 315 light years distant from the Sun. Delta Mus- an apparent visual magnitude of 3.61, 4.

It was one of 12 constellations created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman, and it first appeared on a celestial globe 35cm (14in) in diameter published in 1597 (or 1598) in Amsterdam by Plancius and Jodocus Hondius. A name is preferred even if its a random made up one by yourself. Location. Beta Muscae is a member of the Scorpius-Centaurus association of stars with similar ages, trajectories and locations, which likely formed together in the same molecular cloud. FACT: The commonly quoted Hipparcos Satellite is an abbreviation of The High Precision Parallax Collecting Satellite, which is an astrometric satellite used by the European Space Agency (ESA). It has an apparent magnitude of 4.11 and is approximately 302 light years distant. There are 4 non-Messier deep space objects that are covered on this site and the list is below. It is the farthest right star in the constellation and marks the flys tail. You will be elated to know that this is the smallest constellation known to us to date. Musca ("the fly") is a small southern sky constellation which was created by Petrus Plancius in the late 16th century, with the astronomer having based it upon the observations made by Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman while on their voyage to the East Indies (Southeast Asia).The constellation's brightest star is Alpha Muscae, a blue-white subdwarf found . Many of the constellation's brighter stars are members of the ScorpiusCentaurus association, a loose group of hot blue-white stars that appears to share a common origin and motion across the Milky Way. Quick Facts about Musca: In the Constellation of Muscathe brightest Star is named, Alpha Muscae (a Mus) and is a Blue White-hued Star. Musca constellation pronounciation is Muss-car. [ 24] Seu nome vem da frase rabe al-Maraqq, significando "os quadris" ou "a tanga", uma frase traduzida dos textos de Ptolemeu. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The other . [69] Another dark nebula in the constellation is BHR 71. Sky Chart #: 2. When it becomes a large group of stars, again bound together in the same way, by gravity, it is known as a Galaxy or Star Cluster. The list will provide the name of each constellation plus what the constellation stands for. Musca, the southern fly Constellation, is regarded as a fairly small and faint constellation in the Southern Hemisphere. There are 5 Constellations that are visible throughout the year, from most locations located north of the celestial equator, making them Circumpolar, they are: FACT: A constellation that is visible all year round is known as a Circumpolar Constellation. It is made up of gas, dust and stars, with spiral arms wrapped around it, and a massive black hole in the center of the Galaxy. In a telescope, the nebula appears S-shaped, similar to a barred spiral galaxy, which is how it got the name Spiral Planetary Nebula. [36] It consists of a spectroscopic binary system composed of the WolfRayet star (spectral type: WC5 or 6) and an O-type main-sequence star (spectral type: O6 or O7) that orbit each other every 19 days and a blue supergiant (spectral type: O9.5/B0Iab) set about 46milliarcseconds apart from them. [16] With an apparent magnitude of 3.62, Delta is an orange giant of spectral type K2III located around 91light-years away. Apus; Circinus; Carina; Centaurus; Chamaeleon and Crux. The nebula is not to be confused with the less famous Hourglass Nebula which is located inside the Lagoon Nebula (Messier 8) in Sagittarius. Symbolism: Musca is also known as 'The Fly' History & Mythology. The comparatively old globular cluster NGC 4833 near Delta Muscae was catalogued by Lacaille in 1755. This artificially colorized image was taken with the Wide Field and Planetary Camera 2 aboard NASAs Hubble Space Telescope. It belongs to the stellar class A7III, which means that it is a white giant star, significantly hotter than our Sun. [37] All three are highly luminous; combined, they are likely to be over a million times as luminous as the Sun. The stars are similar in size and appearance. 2.) The nearest star to Earth is HIP 57367 which is roughly about 15.03 Light Years from the Earth. Toucan). The southern fly Constellation can be spotted in the Southern Hemisphere, also referred to as the Southern celestial sky. The average distance to the main Stars in the small Southern Constellation Musca is around 250 light years away. It is a small constellation covering an area of only 138 square degrees. (Uranometria is a well-known Star Atlas compiled by German astronomer Johann Bayer). Constellations have been represented in many cultures as signs and navigational guides. Musca was one of the 12 constellations established by the Dutch astronomer Petrus Plancius from the observations of the southern sky by the Dutch explorers Pieter Dirkszoon Keyser and Frederick de Houtman, who had sailed on the first Dutch trading expedition, known as the Eerste Schipvaart, to the East Indies. The Engraved Hourglass Nebula (MyCn 18) a planetary nebula deep space object located around 8000 light years away, with an apparent magnitude of 13.00 It is not located in our solar system. [1] [2] At its unveiling in 1914, the work was considered the largest sculptural group in the world. A . The stars outer layers were likely blown off by the supernova that produced the black hole. It can be when refering to the constellation shortened or abbreviated to Mus. These are small burnt out husks of stars, about the same size as the Earth. Its more easily visible from the Southern Hemisphere at latitudes between +10 degrees and -90 degrees and covers an area of 138 square degrees in the Southern sky. The Constellations change their positions throughout the year as the Earth rotates around the Sun. Lacaille had originally labelled the fainter one as Zeta, while Baily presupposed he had meant to label the brighter one. The Planets 2010 - 2022 | Privacy Policy & Affiliate Disclaimer, Copyright 2022 ThePlanets.org | Sitemap, Crux Constellation (also known as the southern cross). He later renamed it Musca Australis, the Southern fly to distinguish it from the now defunct Constellation of Musca Borealis, which was composed of a few Stars in Constellation Aries. If it has a negative number it indicates it is located in the southern hemisphere, Initially, the shapes of their star patterns informally categorized the image we had of a constellation. As the Musca Constellation is made up of Stars that are in many different locations and vast distances from each other it is now possible to go to just one location to view it. The Planets. [15] Altogether there are 62 stars brighter than magnitude 6.5 in the constellation. The brightest star in the constellation is Alpha Muscae, with an apparent magnitude of 2.69.

Crux is not visible north of "20 o in the northern hemisphere, and it is circumpolar south of 34 o S, this means that it never sets below the horizon. Dec 31, 2020 - Musca is a small constellation in the southern celestial hemisphere. It is visible from many different locations. Pronunciation: Comments (1) Auriga is a constellation of stars shaped like a pentagon. The Greeks were the first ancient culture to name the early modern Constellations in the sky. . Musca has several notable stars and deep sky objects, among them Nova Muscae 1991, the binary system with a black hole, the Spiral Planetary Nebula (NGC 5189), the Hourglass Nebula (MyCn 18), the globular clusters NGC 4833 and NGC 4372 and the Dark Doodad Nebula. [8] It is 21,200light-years distant and somewhat obscured by dust clouds near the galactic plane. It is circumpolar across much of the southern hemisphere, but appears highest in the midnight sky in the months around March. In astronomy and navigation terms, the celestial sphere is imaginary. A. A constellation is a pattern of stars in a recognisable shape that is supposed to resemble an object, animal or mythical person. Musca constellation is located in the southern sky, just to the south of Crux, the Southern Cross. HD 102839 has an apparent magnitude of 4.98 and an absolute magnitude of -3.27.

[28] To the northwest lies Mu Muscae, an orange giant of spectral type K4III that varies between apparent magnitude 4.71 and 4.76, and has been classified as a slow, irregular variable. Lacaille designated the star Lambda Chamaeleontis in his Coelum Australe Stelliferum, but when the constellation borders were redefined in 1930, the star was placed in Musca rather than Chamaeleon constellation. Plancius did not use any names for the constellation until 1612, when he named it Muia on his globe, which is Greek for the fly.. Musca (Constellation) takes up 138.355 sq. They belong to spectral classes B2 V and B3 V. Beta Muscae A has an apparent magnitude of 3.51 and Beta Muscae B has a magnitude of 4.01. Dutch explorer Pieter Dircksz Keyser called the constellation De Vlieghe, meaning the fly in his native language, with Dutch cartographer Petrus Plancius later adding it to his list of 12 southern sky constellations. Hevelius,Firmamentum, 1690 History of the constellation. It is around 8 times bigger than the Sun, and shines with an apparent visual magnitude of 3.61.

The name Musca is Latin for the fly and its Latin genitive Muscae and a common abbreviation is Mus. It can make up part of a constellation or cross the boundaries of an official constellation or even a defunct constellation. It shines with a visual magnitude of 2.69, making it the brightest star in Musca, but as a Beta Cephei variable it shows a subtle 1% variation in its luminosity due to surface pulsations. The genitive form of Musca, used in star names, is Muscae (pronunciation: /msi/). Musca is a southern celestial hemispheric constellation. [4] The first depiction of this constellation in a celestial atlas was in the German cartographer Johann Bayer's Uranometria of 1603,[5] though Bayer termed it Apis "the Bee", a name by which it was known for the next two centuries. The many Constellations in the night sky were a useful navigation tool and guide as well as the subject of legends and myths. The Planets, https://theplanets.org/constellations/musca-constellation/. NGC 4372 is a globular cluster in Musca. The star is recognised as being the brightest in the constellation as it has the Bayer status of Alpha. It is completely visible in latitudes south of 15 degrees between February and April. Main Stars: Crux consists of 4 main stars. The Bayer designations are stellar designations where the stars within Constellations are initially identified by a name or a letter from the Greek Alphabet from Alpha through Omega (in order of brightness). The Constellation of Musca is circumpolar across much of the Southern Hemisphere, although it appears at its highest in the late night sky around the month of May. Musca is one of the more southern located constellations that are close to the south celestial pole. A Bayer designation for a Star is where the Alpha letter is normally allocated to the brightest star in front of its Latin genitive name (Muscae), then Beta and so on in decreasing order through the letters of the Greek alphabet (although not all the Greek letters are used in every constellation). In 1756 the French astronomer, Nicolas Louis de Lacaille called it La Mouche, in his records of the Southern Sky. # 2. There are 3 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. With an apparent magnitude of 15.99, the nebula is a challenging target for amateur telescopes. Lambda Muscae represents the tip of the tail. Other types of stars include the Orange Giant, Neutron stars, Variable Stars and Binary Stars. James Miller It was on one such voyage to the East Indies that Pieter Dirkszoon Keyser cataloged around 130 Stars and recorded 12 new Constellations in the Southern Sky. Some Scientists Certainly Think So. [17] Marking the fly's tail is Gamma Muscae,[16] a blue-white star of spectral type B5V that varies between magnitudes 3.84 and 3.86 over a period of 2.7days. [46] Finally, SY Muscae is a symbiotic star system composed of a red giant and white dwarf, where although the larger star is transferring mass to the smaller, no periodic eruption occurs nor does an accretion disc form. [51] With around 1.54times the mass of our Sun, it is cooling and expanding along the red-giant branch, having left the main sequence after exhausting its core supply of hydrogen fuel. Latitude: +10 to -90. It is partially obscured by dust of the galactic plane. Stewart, Suzy. The Earth is titled at 23.44 which is why the two differ. All messages will be reviewed before being displayed. It is located around 315 light years from Earth. They are eight and six times as massive as the Sun, respectively, and have about 3.5times its diameter. It was Greek Astronomer Ptolemy, who first cataloged the 48 early constellations, in the 2nd Century (2 AD. It lies in the third quadrant of the southern hemisphere (SQ3) and can be seen at latitudes between +5 and -90. This NASA/ESA Hubble Space Telescope image shows the dazzling stellar group in all its glory.

The origin of the constellation is uncertain, although it probably was not created earlier than the beginning of the seventeenth century. These are giant, bright stars that range from 10-100 times the size of the Sun and are 1000 times brighter. Followed by the genitive form of their parent constellations Latin name Muscae, 3. Planets are continually being discovered and lists updated. It is a yellow supergiant star with the stellar classification of G5Ib. Then, Abb Nicolas Louis de Lacaille named it Musca Australis vel Indica (The Southern or Indian Fly), which distinguished it from the . Musca is a small constellation which can be spotted in the southern sky near to Crux or Southern Cross. These are the remains of a White Dwarf after it cools and darkens. Hubble has observed many of these clusters during its time in orbit around our planet, each as breathtaking as the last. Crux spreads out for around 68 square degrees in the sky.

This section provides a complete list of the Constellations. The name was later shortened to simply Musca. Before we dive deep into the Musca constellation, lets look first at what a constellation actually is. [14], The pattern of the brightest stars resembles that of Ursa Minor, in that the stars form a pattern reminiscent of a bowl with a handle. Reluctant to remove Lacaille's designation, he gave them both the Zeta designation. There is no Greek Legend behind this constellation. Its outline forms the shape of an insect from the position of its six brightest Stars, in the Southern Sky. Co-ordinates of a right ascension, or left ascension and their declination are used to locate all of the Constellations, like Musca. Muscais not connected with any Greek or Roman myths or gods. Mu Mus an apparent visual magnitude of 4.75, 8. The smallest, on the other hand, is Crux with an area of 68 square degrees to its credit.

A Nebula is a massive cloud of gas and dust in Space. Jean Fortin retained the French name in 1776 for his Atlas Cleste, while Lacaille latinised the name for his revised Coelum Australe Stelliferum in 1763. [67] It is 18,900light-years away from Earth and 23,000light-years distant from the centre of the Milky Way. These are main-sequence stars like the Sun, but only 80% of its size, and are bright stars. HD 115211 is an orange supergiant star with the stellar classification of K2Ib-II. He catalogued stars that became Lambda and Mu, but did not designate them as he considered them informes as they lay outside the asterism proper. The Musca Constellation is bordered by several other Constellations: It is most visible in the Southern Hemisphere in the evening around 21.00 hours, during the month of May, but because the stars are in different locations and different distances it is not possible to go one location to view it. It is listed as the 77th largest Constellation as it fills around 0.3% of the night sky. The notable deep sky objects, includes objects from the Henry Draper Catalogue of Stars (abbreviated to HD and a designated number as an identifier), or the Index catalogue classification (IC). If the system's estimated distance from Earth is accurate, the binary stars are about 0.5astronomical units (AU) apart and the supergiant about 100AU apart from them. It was discovered by the Scottish astronomer James Dunlop in July 1826. Constellations like Musca are not part of our Solar System; they are groups of stars that appear to form shapes that are visible with the naked eye from Earth. The Coal Sack Nebula is located in the Constellation of Crux (the Southern Cross), which overlaps with the neighboring Constellations of Centaurus and Musca. Francis Baily also dropped Kappa, which he felt was too faint to warrant a name, and designated two adjacent stars as Zeta1 and Zeta2. There are no named Stars within Constellation Musca that are approved by the IAU. These include Alpha, Beta, Gamma, Zeta2 and (probably) Eta Muscae, as well as HD 100546, a blue-white Herbig Ae/Be star that is surrounded by a complex debris disk containing a large planet or brown dwarf and possible protoplanet. [59] Its complex structure is due to multiple ejections of material from the ageing central star, which are distorted by the presence of a likely binary companion. Musca is a member of the Johann Bayer family of Constellations that includes (in alphabetical order): The different components usually housed by Constellations are mainly Stars, Deep Sky Objects and Messier objects (galaxies).
