It's not a mindless ramble for these folks, either. Would you prefer to share this page with others by linking to it? Satyrs have two legs while centaurs have four. It was discovered by James Dunlop on June 2, 1826. It is between 18,000 and 19,000 light years distant and has an apparent magnitude of 7.66. Each appears in a different hue red, orange, yellow, and green-tinted bands of gas are visible, with clear patches of space at the heart of the nebula. The cluster lies at a distance of about 16,000 light years and has a magnitude of 9.30. It lies at a distance of 5,500 light years from Earth. It can be observed through a small telescope and is a popular deep sky object among amateur astronomers. It has a diameter of about 20 kilometres and its rotation speed at the surface is 30,000 km/h. VX Sagittarii, currently (as of 2017) one of the five largest known stars in the Milky Way, is an evolved red supergiant or hypergiant (M4eIa M10eIa) with a radius between 1,350 and 1,940 times that of the Sun and a mass 12 times solar. Edwin Hubble identified 15 variable stars in Barnards Galaxy, 11 of which were Cepheids, luminous variable stars that have a strong relationship between luminosity and pulsation period, which makes them excellent standard candles (objects with a known luminosity) for determining galactic and extragalactic distance scales. In Sagittarius Mythology, Sagittarius is described as The Centaur (one-half horse, one-half human). It is approximately 149 light years distant. The stars traditional name, Kaus Media, means the middle bow. The primary star in the Delta Sagittarii system has three dim companions: Delta Sagittarii B, a 14th magnitude star 26 arc seconds away, Delta Sagittarii C, a 15th magnitude star 40 arc seconds away, and Delta Sagittarii D, a 13th magnitude star 58 arc seconds away. In Greek mythology, Sagittarius is commonly thought to represent a centaur, a war-like creature with the torso of a man and the body of a horse. Most stories come to the conclusion that the myth of the constellation Sagittarius is the tale of the centaur Chiron. NGC 6624, based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA). The companion star has an apparent magnitude of 5.84 and is located about 359 light years from Earth. The third star in the system is an O-type star with an apparent magnitude of 15.36. It has a faint 14th magnitude companion 32 arc seconds away. Some stars maintain relatively circular orbits, while others loop out into the clusters fringes. It has a radius of 0.95 arc minutes. It is also catalogued as ESO 456-70. It has an estimated age of 13.06 billion years. It contains very few variable stars. Greek mythology held that both satyrs and centaurs were mostly huge, boorish jerks, but Crotus and Chiron were the exceptions: intelligent, kind, sensitive, and sympathetic to humans. NGC 6578, image: Judy Schmidt (CC BY 2.0). This image is a tiny part of just one of eleven public surveys of the sky now in progress using ESO telescopes. Planetary nebulae are illuminated for around 10 000 years before the central star begins to cool and shrink to become a white dwarf. Being half human aligned the centaur with intellect and civility, while the horse end symbolized. The clouds have an ionized surface. Its estimated age is 90 million years. This galaxy is currently colliding with, and being absorbed by, the Milky Way, which is a monster in size when compared to this tiny one. Sagittarius embodies adventure and the pursuit of meaning. Messier 18 is an open star cluster in Sagittarius. The cluster is believed to be only 2.5 million years old. It has a mass three million times that of the Sun. The myth of Sagittarius being cold-hearted is a mere misconception that is based on surface level observations. The image was made from data obtained through four different filters (B, V, R, and H-alpha). Tau Sagittarii is an orange giant star belonging to the spectral type K1 or K2, approximately 120 light years distant. It was discovered by William Herschel on May 22, 1784. The dark nebula Barnard 86 (B86) can be seen near the clusters western edge. Vast amounts of energy are also released when these stars go out as supernovas, heating the surrounding material. It was discovered by Charles Messier in 1764. The cluster has a diameter of 10 arc minutes and an apparent magnitude of 4.6. It was discovered by William Herschel in 1784 using his 18-inch telescopes. Alpha Sagittarii is a blue dwarf belonging to the spectral class B8V. The cluster is about 19 light years across. Both centaurs and satyrs were well known to be wild, rowdy, lustful creatures that had little respect for authority and proper manners. Mu Sagittarii is a multiple star system in Sagittarius, with individual components designated Polis A through Polis E. Its traditional name, Polis, comes from the Coptic Egyptian word for foal.. The stars luminosity is uncertain it is estimated to be about 3.2 million times that of the Sun because the star is heavily obscured by dust and not visible in optical bands. NGC 6589 is a reflection nebula that occupies an area of 5.0 by 3.0 in apparent size. Because he was close to the Muses, they were the ones who asked Zeus to place him in the sky. Myth of Sagittarius. It was discovered by William Herschel on June 24, 1784. The star cannot be observed in visual bands because less than a billionth of its light in the visible spectrum reaches us, which translates to about 35th visual magnitude. Satyrs have human heads and torsos with goat legs (and sometimes horns). Emerson/VISTA. Edward Emerson Barnard catalogued it as IC 4690 in August 1905. First discovered by amateur Japanese astronomer, Yukio Sakurai, in 1996, and noted as a nova-like object, Sakurais discovery turned out to be far more interesting than the supernova he initially supposed it to be. Chiron was immortal, so he could not die. The Quintuplet Cluster contains more Wolf-Rayet stars than any other cluster known and several notable luminous blue variables, including the Pistol Star, V4650 Sagittarii and the runaway star V4998 Sagittarii. Image: European Space Agency, A. Riera (Universitat Politecnica de Catalunya, Spain) and P. Garcia-Lario (European Space Agency ISO Data Centre, Spain). Because it has an imposing size and energy, Sagittarius A East is believed to be a remnant of a star that came close to the central black hole and was gravitationally compressed. Image: Smithsonian Institution, NASA/CXC/UMass Amherst/Q.D.Wang et al. The nebula is an H II region originally discovered by the Swiss astronomer Jean-Philippe Loys De Chseaux in 1745. Lambda Sagittarii is an orange giant star, belonging to the spectral class K1+IIIb, with an apparent magnitude of 2.82. Located on the far side of our galaxy, the cluster is heavily obscured by dust, but visible in infrared wavelengths. Messier 28 is a globular cluster located near Lambda Sagittarii (Kaus Borealis). NGC 6522 is a globular cluster with an apparent magnitude of 10.5, lying at a distance of 25,100 light years from Earth. The cluster has an apparent magnitude of 11.29 and lies at a distance of 24,100 light years from Earth. Quarters are always tight in globular clusters, where the mutual hold of gravity binds together hundreds of thousands of stars in a small region of space. Return from Sagittarius Myth to the Constellation Myths page. He even invented the bow, according to Greek mythology. NGC 6578 is a planetary nebula occupying an area of 8 arc seconds. This story does indeed refer to a constellation myth, but it's actually the myth behind the constellation Centaurus, not Sagittarius. This image from the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESOs La Silla Observatory in Chile, shows the bright star cluster NGC 6520 and its neighbour, the strangely shaped dark cloud Barnard 86. Image: NASA/CXC/MIT/F.K.Baganoff et al. Nir al Beldat was later translated into Latin as Lucida Oppidi, which means the brightest of the town.. However, this does not make them cold . This, however, only applies to Mars and it happens very rarely. The estimated age of the cluster is more than 12 billion years, making NGC 6522 one of the oldest known clusters in the Milky Way. The white dwarf emits sufficient ultraviolet radiation to illuminate the gas it has expelled, which can just be seen in this image as the ring of red material. Alternatively, some mythology identifies Sagittarius as the son of Pan, the god who created archery. This image was taken using the FORS instrument, mounted on ESOs Very Large Telescope. The system is also known by its traditional name, Arkab, from the Arabic carqb, which means hamstring.. Globular clusters are dense collections of old stars. The Delta Sagittarii system is known in fiction from William R. Forstchens 1969 novel Into the Sea of Stars. The name is derived from the Arabic word rukbah, which means knee.. In this image of ESO 456-67, it is possible to see the various layers of material expelled by the central star. It is classified as a UV Ceti-type flare star, one undergoing sudden dramatic increases in brightness for a few minutes. A gas giant planet was discovered orbiting the orange dwarf HD 164604 (K3.5Vk) in 2010. Nunki has a faint (magnitude 9.5) companion about 5.2 arc minutes away. It lies at a distance of 35,500 light years. It is one of the 48 constellations listed by the 2nd-century astronomer Ptolemy and remains one of the 88 modern constellations. Crotus and Chiron were both exceptions to their races, being instead gifted in the arts and sciences and were knowledgeable and polite to humans. It lies at a distance of 26,100 light years from Earth. Most sources identify Sagittarius as Chiron, the son of the Titan Cronus, according to Globe at Night. The field of view is 35 x 34 arcmin. He later included it in his catalogue. Yet, it isn't the correct one, according to Gods and Monsters, which holds that the constellation Zeus created in Chiron's honor was actually Centaurus, a constellation that borders Libra (via Sea and Sky). It is obscured from view by large cosmic dust clouds in the galaxys spiral arms. The Quintuplet Cluster is another dense open cluster located in same region as the Arches Cluster, about 26,000 light years from Earth and 100 light years from the centre of the Milky Way. It is a 10th magnitude star. It has an apparent size of 4.75 by 4.75. Flower: Carnation Like a carnation, those born under the sign of Sagittarius are strong, yet beautiful. Obscured by clouds of dust, it cannot be observed in the visual bands, but is visible in radio, infrared and X-ray wavelengths. The cluster is about 34 light years in radius, has an apparent magnitude of 9.06 and is approximately 29,300 light years distant. Ancient Greeks on the other hand had tremendous respect for horses. A stars final moments are captured in this image from the NASA/ESA Hubble Space Telescope. What is the flower of Sagittarius? It has a mass of about 36 solar masses, which now puts it behind more than a dozen massive stars, including four members of the Arches Cluster. The two nebulae are probably part of the same larger star-forming region. signal, the first and only radio signal ever received that indicated the possibility of extraterrestial intelligence. The archer's best-known identity was that of a centaur, a beast with the upper body of a man and the lower body, hind legs, and tail of a horse. The myth behind Sagittarius actually refers to Crotus, a satyr that lived on Mount Helicon with the Muses. It was discovered by Italian astronomer Giovanni Battista Hodierna in 1654. In these clusters, even more stars squeeze into the objects core than on average, such that the brightness of the cluster increases steadily towards its centre. In total, there are about 400,000 stars in the globular cluster. Centaurs have four legs, and are half-man, half-horse; satyrs have two legs and are half-man, half-goat. NGC 6520 is an open star cluster with an apparent magnitude of 9.0. Messier 23 is an open star cluster, discovered by Charles Messier in June 1764. On 27 December, 2004, the brightest gamma ray burst ever detected outside the solar system was recorded emanating from the star, with an absolute magnitude of about -29. The Mythology Behind The Sagittarius Constellation Explained. They are believed to be a type of magnetar. Hurt 2, or 2MASS-GC02, is a globular cluster discovered only recently, in 2000. This is the most popular version of the Sagittarius story. Pi Sagittarii is also sometimes known as Albaldah, from the Arabic blda, which means the town. Egyptian astronomer Al Achsasi al Mouakket designated it Nir al Beldat in his star catalogue Calendarium in the mid-17th century. Image: ESO/J. The constellation has 32 stars with confirmed planets. In mythology, Centaurs were hard drinkers, unreliable, misleading, crude, wild, and adulterous. Polis is about 3,912 light years distant from Earth. It was discovered by Philippe Loys De Chseaux in 1745 and added to Messiers catalogue in 1764. The nebula is in fact a combination of an emission nebula (the lower part), a reflection nebula (the upper part) and an open cluster. The signs are: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Hurt, who led the team that confirmed the discovery. Charles Messier discovered it in 1780 and subsequently included it in his catalogue. It is one of the stars that mark the handle of the Teapot asterism. Sometimes, Sagittarius is also associated with the Greek goddess Tyche and the Norse God Thor. The galaxy was named after the American astronomer E.E. The Teapot in Sagittarius, image: Wikisky. Crotus, much like Chiron, was a skilled musician and hunter. The cluster spans 10 light years and has an apparent size of 5 arc minutes. LBV 1806-20, a candidate luminous blue variable (LBV) is one of the most luminous stars in our galaxy. In this image, the NASA/ESA Hubble Space Telescope has captured the brilliance of the compact centre of Messier 70, a globular cluster. With a mass of 10,000 solar masses, it is about 10 times more massive than typical open clusters in the Milky Way. Image: Subaru Telescope (NAOJ), Hubble Space Telescope, Martin Pugh; Processing: Robert Gendler. The clusters age and low levels of nickel found in it led astronomers to believe that it may have originated in the Sagittarius Dwarf Spheroidal Galaxy (Sag DEG). About 25 stars in the cluster are of magnitude 9 to 12. At the time of discovery, LBV 1806-20 was thought to be the most luminous and most massive star ever discovered. This dazzling image shows the globular cluster Messier 69, or M69 for short, as viewed through the NASA/ESA Hubble Space Telescope. (In 2003, the Canis Major Dwarf Galaxy was discovered and recognized as the nearest neighbour.). The binary system has a combined apparent magnitude of 2.60. When this happens, the stars light drastically diminishes and ceases to excite the surrounding gas, so the nebula fades from view. Sags are truth-seekers, and the best way for them to do this is to hit the road, talk to others and get some answers. It has an absolute magnitude of -11 and a luminosity about 2 million times that of the Sun. Image: ESA/Hubble & NASA. V4641 Sagittarii is the fourth known microquasar, discovered after four of the fastest X-ray intensity changes ever seen from a star. Individuals born between November 22 and December 21 are known to be Sagittarius individuals. The cluster was discovered by William Herschel on 24 June, 1784. Most of the centaurs were regarded in myth as bestial--they were, after all, half horse. This vast ball of ancient stars is located at a distance of about 17,000 light-years from Earth. Its estimated age is between 3 and 4.5 million years. The last occultation occurred on September 3, 423. The cluster is a relatively large and bright one, with an apparent magnitude of 7.42. They are in fact located behind the nebula. The brightest one has a magnitude of 9.2. In Greek mythology, Sagittarius represents a centaur, a half human, half horse creature with the torso of a man and the body and four legs of a horse. This is unusually young for such a cluster. It is one of the stars that form the Teapot asterism; it marks the junction of the handle and the lid of the Teapot. The red dwarf MOA-2009-BLG-387L, located almost 20,000 light years away, is host to an orbiting planet with a mass between 1.0 and 6.7 times that of Jupiter. The last time this happened was on November 19, 1984, when Venus passed in front of the star, eclipsing it. It is approximately 77.3 light years distant. Sagittarius was characterized in mythology as being unrestrained as wild or untamed horses despite their human head, arms, and torso. Astronomers recently discovered that all the stars in Terzan 7 were born at around the same time, and are about eight billion years old. Image: NASA, ESA, STScI, and G. Piotto (Universit degli Studi di Padova), and E. Noyola (Max Planck Institut fr extraterrestrische Physik). The star was last occulted by a planet on November 17, 1981, when Venus passed in front of it. It is not fully understood how planetary nebulae form such a wide variety of shapes and structures; some appear to be spherical, some elliptical, others shoot material in waves from their polar regions, some look like hourglasses or figures of eight, and others resemble large, messy stellar explosions to name but a few. Sagittarius is one of the largest southern constellations. It has an apparent size of 5.2 by 5.2. Chiron and Achilles. The Bubble Nebula is an emission nebula located in Barnards Galaxy. However, the ancient Greeks had a great deal of respect for the horse, and so were reluctant to make the centaurs entirely bad. It's just a matter of which stars you think go with which other ones. The Sagittarius Cluster is one of the brightest globular star clusters in the sky. NGC 6818 is a magnitude 10 planetary nebula in Sagittarius. It is an H II region, containing a stellar nursery full of embryonic stars. The Arches Cluster is the densest open cluster known in the Milky Way. M69 has a radius of 42 light years and an apparent magnitude of 8.31. According to the Roman author Hyginus, Crotus was the son of Pan and the archer the constellation was named after. The two-lobed nebula surrounds the central hot white dwarf that produces a hot wind with a speed of 300 km/s. The star has a luminosity 3,300 times that of the Sun and about seven solar masses. It has an apparent magnitude of 5.1 and is approximately 10,600 light years distant. Beta Sagittarii is a designation shared by two star systems, Beta-1 Sagittarii and Beta-2 Sagittarii, which lie 0.36 apart in the sky. It is one of only four star systems known to be hydrogen-deficient, which makes it difficult to classify U Sgr. It is an eclipsing binary star, with a B8 supergiant star for a primary component and a B2 type giant as the companion star. The Ancient Gods of Greek Myth The psychological branch of Astrology uses the concept of primeval images, or ' archetypes ' constellated at the very roots of a person's being. Westerhout 31 (W31) is a massive H II region in Sagittarius. NGC 6553 is a globular cluster found just over a degree to the southeast of the Lagoon Nebula. Named for its most prominent five stars, the cluster was only discovered in 1990. Image: ESO/VPHAS+ team. The nebula lies at a distance of 6,000 light years from Earth and has an oval diameter of 15 to 22 arcseconds. The constellation of Sagittarius (which literally means "archer" in Latin, per Britannica) is said to be a centaur or satyr holding a bow and arrow, according to Gods and Monsters. Sagittarius is one of the 88 modern constellations, . Sagittarius is one of the 12 zodiac constellations that was first catalogued by the Greek astronomer Ptolemy in the 2nd century. The cluster has an apparent magnitude of 6.9 and is about 2,150 light years distant. Hubble established a distance of over 700,000 light years using the Cepheids period-luminosity relationship, and this was the first system located beyond the Magellanic Clouds to have its distance accurately determined. Upsilon Sagittarii is a spectroscopic binary star. It is approximately 29,700 light years distant from Earth. Sagittarius Dwarf Irregular Galaxy (SagDIG), image: NASA, ESA, and The Hubble Heritage Team (STScI/AURA), acknowledgement: Y. Momany (University of Padua). Even though Chiron was skilled in medicine, he also could not heal himself, putting him in great pain. The cluster is one of six globulars discovered by the French-Armenian astronomer Agop Terzan in 1968. The cluster is heavily obscured and has an apparent magnitude of 12.8. They both were known to hunt with a bow and arrow (though this is a bit misleading as centaurs did not traditionally use a bow and arrow. The Carina-Sagittarius Arm is particularly notable for containing a large number of H II regions, giant molecular clouds and young stars. The cluster was first observed by Charles Messier in June 1764. The nebula expands at the velocity of about 32 km/s and occupies an area of 44 arc seconds. In Sagittarius Mythology, Sagittarius is described as The Centaur (one-half horse, one-half human). In English, the constellation is known as the Archer. Knowledge is key to these folks since it fuels their broad-minded approach to life. The clusters NGC 6522 and NGC 6528. The constellations symbol is . The brightest stars in the cluster are 16th magnitude. Hercules accidentally shot Chiron with a poisoned arrow while hunting, and since he. VX Sagittarii lies at an approximate distance of 5,150 light years from Earth. It must be observed in infrared wavelengths. Sagittarius constellation map by IAU and Sky&Telescope magazine. This Chandra image of Sgr A* and the surrounding region was made from a 164 hours of observation time over a two-week period. The primary component in the star system is a class B giant 23 times as massive as the Sun, and 180,000 times more luminous. Terzan 5 has a mass of about 2 million solar masses and bolometric luminosity 800,000 times that of the Sun. The gamma ray burst was so powerful that it hit the Earths ionosphere and briefly expanded it. It is made of clouds of dust and gas that circle Sagittarius A* and fall onto it at exceptionally high velocities, up to 1000 kilometres per second. The brightest stars in the cluster are 7th magnitude. Pistol Star and Nebula (false colour composite image), photo: Don F. Figer (UCLA) and NASA. Because the stars in globular clusters are ancient, their metallic abundances are much lower than more recently formed stars, such as the Sun. Messier later included it in his catalogue. The galaxy was discovered on a photographic plate taken for the ESO Atlas in June 1977. Others suggest that clusters like Terzan 7 only have enough material to form one batch of stars, or that perhaps its youthfulness has prevented it from yet forming another generation. Another aspect of M69 lends itself to the bejewelled metaphor: As globular clusters go, M69 is one of the most metal-rich on record. The cluster was discovered by William Herschel on May 24, 1784. Other stars with confirmed exoplanets include HD 171238 (G8 V), HD 179949 (F8 V), HD 181720 (G1V), HD 187085 (G0V), WASP-67 (K0V), MOA-2011-BLG-293L (M1.5V), MOA-2009-BLG-319L (K8V), HD 181342 (K0III), HD 180902 (K0III/IV), OGLE-TR-56 (G), OGLE-2003-BLG-235L (K5), OGLE-2005-BLG-169L (M), MOA-2007-BLG-192L, and MOA-2007-BLG-400L (M3V). The star marks the base of the archers bow. 62 Sagittarii (or c Sagittarii) is an M-type giant at the southwest corner, about 450 light years from Earth. The cluster can be seen only 0.8 degrees to the southeast of Delta Sagittarii. As a beloved archer, you will join the ranks of others who chased their dreams and adventures, such as Samuel L. Jackson, Taylor Swift, and Brad Pitt. Centaurs are considered beasts in mythology due to the fact that they are half horse. It cannot be seen visually, but must be observed in radio, X-ray and infrared bands. The companion can be found 3.6 arc seconds from the primary star. Once enough material was ejected, the stars luminous core was exposed and it began to produce ultraviolet radiation, exciting the surrounding gas to varying degrees and causing it to radiate in an attractive array of colours. The cluster has a highly concentrated core, with the majority of M75s stars located in a large nucleus. The nebula was discovered by Edward Charles Pickering on July 15, 1882. It is good to remember the reason why Sagittarius is a centaur in the first place. In mythology, Centaurs were hard drinkers, unreliable, misleading, crude, wild, and adulterous. The primary component, Arkab Prior A, is a B9 type main sequence dwarf with an apparent magnitude of 3.96, while the companion star, Arkab Prior B, is a class A3 dwarf with an apparent magnitude of 7.4. A transiting planet was spotted orbiting the magnitude 16 eclipsing variable star OGLE-TR-10 (G2V) in 2002. The stars are 28 arc seconds apart. Located in the Galactic centre region, the Pistol Star lies approximately 25,000 light years from our solar system. The soft gamma repeater SGR 1806-20 is a magnetar, a neutron star with an exceptionally strong magnetic field, more than 1015 gauss (1011 tesla) in intensity , or 1-2 quadrillion (short scale) times that of the Earth. The nebula was discovered by Truman Safford on 28 August, 1867. Sagittarius B2 is a very large molecular cloud of dust and gas approximately 390 light years from the centre of the Milky Way. Artist conception of the December 27, 2004 gamma ray flare expanding from SGR 1806-20. The huge number of stars that light up this region dramatically emphasise the blackness of dark clouds like Barnard 86, which appears at the centre of this new picture from the Wide Field Imager, an instrument mounted on the MPG/ESO 2.2-metre telescope at ESOs La Silla Observatory in Chile. Messier 21 is another open star cluster in Sagittarius. Another companion star is only 13th magnitude and can be seen 33 arc seconds away from the primary, while the faintest star in the system is 10th magnitude and is separated from the brightest star by 93 arc seconds. These figures come from Greco-Roman mythology, but it's thought that the ancient Babylonians were the first to identify Sagittarius as an archer, in 11th century B.C. Beta-1 Sagittarii, or Arkab Prior (prior because it leads Beta-2 across the sky), is a double star approximately 378 light years distant. It is the densest concentration of stars that can be seen using binoculars; about a thousand stars are visible within a single field of view. It lies in an area of the sky known as Baades Window. It has an apparent magnitude of 13 and lies at an estimated distance between 3,000 and 8,000 light years from Earth. The small cluster is only 1 arc minute in diameter. It has an apparent magnitude that varies from 6.5 to 14.0 over a pulsational period of 732 days. The neighboring constellations are Aquila, Capricornus, Corona Australis, Indus, Microscopium, Ophiuchus, Scutum, Scorpius, Serpens Cauda and Telescopium. The two brighter components form a close binary system with an apparent magnitude of 13.28. It is a dramatic and short-lived series of events, and Sakurais Object has allowed astronomers a very rare opportunity to study the events in real time. The Box Nebula, catalogued as NGC 6445, is a planetary nebula with a visual magnitude of 11.2. Sagittarius in mythology. Its symbol is . This may indicate that, like the better known Messier 54 and Omega Centauri, Terzan 5 is not a true globular cluster, but possibly the remaining core of a dwarf galaxy disrupted by the Milky Way in the distant past. The star was discovered in February 1996 by Yukio Sakurai, an amateur astronomer. The Omega Nebula is an emission nebula in Sagittarius. Beta-2 Sagittarii, or Arkab Posterior (because it trails after Beta-1), is a giant star belonging to the spectral type F2III. Box Nebula (NGC 6445), image: NASA and STScI. This huddling effect produces the denser, brighter centres characteristic of core-collapsed clusters. While the star is far enough for the supernova itself to be harmless, a long duration gamma-ray burst (LGRB) pointed in our direction could certainly do serious damage to our ozone layer. It is also notable for being one of only four known globular clusters that contain a planetary nebula. 59 Sagittarii (sometimes also known as b Sagittarii) is a K-type bright giant at the southeast corner, about 1,200 light years distant. The star lies at a center of a planetary nebula, formed after the stars red giant stage about 8,300 years ago. NGC 6559, image: Adam Block/Mount Lemmon SkyCenter/University of Arizona (CC BY-SA 3.0 US). M69 is only 1,800 light years away from M70 and located near the Galactic centre. NGC 6624 contains six confirmed pulsars and a low-mass X-ray binary, designated 4U 1820-30, with an orbital period of only 11.5 minutes. Omega Sagittarii is a G-type subgiant marking the northeast corner of the Terebellum, about 78 light years distant from Earth. chris mcneely football coach, steve trulaske yacht, currency exchange krakow airport,
