Musca remains below the horizon for most Northern Hemisphere observers. It is a dark nebula which is part of the Musca molecular cloud. It belongs to the stellar class A7III, which means that it is a white giant star, significantly hotter than our Sun. The first depiction of this constellation in a celestial atlas was in Johann Bayer's Uranometria of 1603. [43] The soft X-ray transient GRS 1124-683 (also known as Nova Muscae 1991) is a binary object consisting of an orange main-sequence star (GU Muscae) of spectral type K3V–K4V and a black hole of around six solar masses. At a distance of 91 light years, it is the nearest star system to Earth in Musca constellation. [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 2.7 days. [64] NGC 4463 is an open cluster located on its southwestern border. Musca Constellation Map, by IAU and Sky&Telescope magazine, Musca was one of the 12 constellations introduced by the Dutch navigators Keyser and de Houtman during their expeditions to the East Indies in the late 16th century. 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. [59] Located 2.4° east of Eta Muscae is the magnitude-12.9 Engraved Hourglass Nebula (MyCn 18),[60] which lies about 8000 light-years distant from Earth. [23] Alpha, Beta, Gamma, HD 103079, Zeta2 and (likely) Eta are all members of the Lower Centaurus Crux subgroup of the Scorpius–Centaurus Association, a group of predominantly hot blue-white stars that share a common origin and proper motion across the galaxy. This snakelike gas cloud (center dark area) in the constellation Musca resembles a skinny filament. See more. [50] With around 1.54 times 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. The star is approximately 1,455 light years distant from the solar system. As a result of the confusion, Avis Indica was renamed to Apus, and Apis, the constellation representing the bee, became Musca, the fly. The two stars orbit each other every 505 days. If the system's estimated distance from Earth is accurate, the binary stars are about 0.5 astronomical units (AU) apart and the supergiant about 100 AU apart from them. 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. [24][25], Delta and Epsilon mark the fly's left wing and right wing, respectively. Gamma Muscae is a blue-white main sequence dwarf. The largest constellation by area is Hydra which is 3.16% of the sky. It is the farthest right star in the constellation and marks the fly’s tail. The smallest is Crux which only takes up 0.17 percent of the sky. A constellation is a group of stars that, when seen from Earth, form a pattern. The nebula is more than 30 light years long and lies approximately 700 light years from Earth. Its goal is to beam superfast internet into your home from space. It has twice the mass of the Sun. Musca constellation is located in the southern sky, just to the south of Crux, the Southern Cross. It has the stellar classification of B2 IV-V. Francis Baily also dropped Kappa, which he felt was too faint to warrant a name, and designated two adjacent stars as Zeta1 and Zeta2. The constellation may also have gotten its name from the tale of Phaethon and Cycnus. The constellation currently lies south of the ecliptic and will keep moving further south as a result of precession. The white dwarf accumulates material from its companion star via its accretion disc. [40], Also known as Nova Muscae 1983, GQ Muscae is a binary system consisting of a white dwarf and small star that is about 10% as massive as the Sun. [49] HD 112410 is a yellow giant of spectral type G8III located around 439 light-years distant. [35], Theta Muscae is a triple star system thought to be around 7,500 light-years distant. A 1603 celestial globe by Willem Blaeu depicts it as providing nourishment for the nearby constellation Chamaeleon—its tongue trying to catch the insect. Its name means “the fly” in Latin. Apus is bordered by Ara, Chamaeleon, Circinus, Musca, Octans, Pavo, and Triangulum Australe. λ Muscae (Lambda Muscae) – HD 102249 (HIP 57363). 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 35 cm (14 in) in diameter published in 1597 (or 1598) in Amsterdam by Plancius and Jodocus Hondius. After a certain amount has accumulated, the star erupts, as it did in 1983, reaching a magnitude of 7.2. The star has the stellar classification of B5V and is approximately 325 light years distant from the solar system. [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. Covering 138 square degrees and 0.335% of the night sky, it ranks 77th of the 88 constellations in size. The constellation, informally known as Starlink, and under development at SpaceX's facilities in Redmond, Washington. [20] Zeta2 Muscae is a white main sequence star of spectral type A5V around 330 light-years distant from Earth. The word "constellation" comes from a Latin term meaning "set with stars." [8] It is 21,200 light-years distant and somewhat obscured by dust clouds near the galactic plane. [57], Located on the border with Circinus is the unusual planetary nebula NGC 5189,[8] estimated to be around 1750 light-years away from Earth. [36] TU Muscae is a binary star system located around 15,500 light-years away made up of two hot, luminous, blue main-sequence stars of spectral types O7.5V and O9.5V,[38][39] with masses 23 and 15 times that of the Sun. Crux is a cross-shaped constellation visible in the southern hemisphere. The Greek astronomer Ptolemy catalog… Good star chart programs or books can provide more information about each constellation and the treasures it … The nebula was discovered by Annie Jump Cannon and Margaret W. Mayall in the early 20th century, while they were working on an extended Henry Draper Catalogue. [22] Eta Muscae is a multiple star system, the two main components forming an eclipsing binary that has a combined spectral type of B8V and magnitude of 4.77 that dips by 0.05 magnitude every 2.39 days. In the beginning, the constellation was dubbed 'Apis , the bee' by Bayer, but it was renamed Musca Australis (the southern fly) by Nicolas … The primary star is an orange giant with the stellar classification of K2III, and the spectral type of the companion star is unknown. Then I guess the bull, that was really Zeus, became the Taurus constellation, but not really, because now the bull and Zeus are different... or something. [18] It is around five times as massive as our Sun. 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 35 cm (14 in) in diameter published in 1597 (or 1598) in Amsterdam by Plancius and Jodocus Hondius. The constellation with the greatest number of visible stars in it is Centaurus (the Centaur - with 101 stars). Each entry describes the mythology and history of the constellation along with an illustration of it from a classic star atlas, usually Johann Bode’s Uranographia of 1801 or John Flamsteed’s Atlas Coelestis of 1729. A planet with at least 6.80 times the mass of Jupiter is orbiting the star with a period of 1,143 days. 42 animals, 29 … The stars are so close that they are in contact with each other (overcontact binary) and are classed as a Beta Lyrae variable as their light varies from Earth as they eclipse each other. Reluctant to remove Lacaille's designation, he gave them both the Zeta designation. The poop deck of the Argo Navis; a sub-division of the ancient constellation Argo – in Greek mythology, the ship of the Argonauts. The Dutch cartographer Petrus Plancius was the first to include the constellation on his globe of 1598, but left it unnamed. It was a star originally 1.5 to 2 times as massive as our Sun. However, the patterns we see in the stars are purely a product of human imagination, so humans are free to amend the patterns as they choose – and astronomers did so at will during the heyday of celestial mapping in the 17th and 18th centuries. [11], Musca is bordered by Crux to the north, Carina to the west, Chamaeleon to the south, Apus and Circinus to the east, and Centaurus to the northeast. The following charts show the sky as seen from latitude 40 degrees North at around 10 p.m. in the middle of each season. [66] It is 18,900 light-years away from Earth and 23,000 light-years distant from the centre of the Milky Way. [68] Another dark nebula in the constellation is BHR 71. [56] It is considered a good candidate to look for Jupiter-like planets, on account if its proximity and mass. Lambda Muscae is a star in a dual system. [30], Located near Alpha is R Muscae,[16] a classical Cepheid variable ranging from apparent magnitude 5.93 to 6.73 over 7.5 days. The black hole in Nova Muscae 1991 has seven times the Sun’s mass, while the companion star has three-quarters of the Sun’s mass and one third of the Sun’s luminosity. NON-astronomers are often puzzled by the concept of a disused constellation – surely, a constellation is either there or it isn’t. Lambda Muscae has an apparent magnitude of 3.68 and is the fourth brightest star in Musca constellation. [45] GR Muscae is an X-ray source composed of a neutron star of between 1.2 and 1.8 times the mass of our Sun and a low-mass star likely to be around the mass of the Sun in close orbit. In de Houtman’s catalogue of 1603, the constellation is called De Vlieghe, which is Dutch for “the fly.”. Musca, “The Fly”, is a late sixteenth-century creation of Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman. In this way astronomers are better able to organize the heavens into some recognizable form, and make locating stars and other astronomical objects easier. It was also known as Apis (Latin for '"the bee"') for 200 years. Small patterns of stars within a constellation are called asterisms. It has an apparent magnitude of 4.11 and is approximately 302 light years distant. HD 102839 has an apparent magnitude of 4.98 and an absolute magnitude of -3.27. MAJOR STARS IN APUS At one point Zeus morphed into a swan to seduce Leda, mother of both Gemini and Helen of Troy. It has an apparent magnitude of 13 and is approximately 8,000 light years distant from Earth. Constellation is an abstract, luxurious and contemporary interpretation of several star patterns specific to the Southern Hemisphere. Spiral Planetary Nebula – NGC 5189 (Gum 47, IC 4274). [55] LP 145-141 is a white dwarf located 15 light-years distant—the fourth-closest to the Solar System. I.

The globular cluster NGC 4372 near Gamma Muscae is fainter and likewise partially obscured by dust, but spans more arc minutes. Musca does not contain any formally named stars. 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. [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.
