Terzan 7 is the brightest of the six globulars discovered by Agop Terzan in 1968. Sagittarius is most often associated with Crotus, the son of Pan (the goat-god) and Eupheme (the Muses' nurse). It has an absolute magnitude of -11 and a luminosity about 2 million times that of the Sun. Messier 54 is a dense globular cluster with an apparent magnitude of 8.37, approximately 87,400 light years distant and about 150 light years across. The significance of the name is unknown, except that it is a proper name. The planetary nebula in the Sagittarius Cluster, designated GJJC1 is believed to be only 6,000 years old and has a blue star at the centre. It has an estimated age of 13.06 billion years. The constellation has 32 stars with confirmed planets. The myth behind Sagittarius actually refers to Crotus, a satyr that lived on Mount Helicon with the Muses. The Gamma designation used to be shared by two star systems in Sagittarius, Gamma-1 and Gamma-2, which were separated by 0.86 in the sky. The clusters NGC 6522 and NGC 6528. Never observed anywhere in the bulge before, this peculiar cocktail of stars suggests that Terzan 5 is in fact one of the bulges primordial building blocks, most likely the relic of a dwarf galaxy that merged with the Milky Way during its very early days. M75 is believed to be around 13 billion years old and sits approximately 67,500 light-years away from Earth. The star was named after the shape of the nebula it illuminates, the Pistol Nebula. The stars are 28 arc seconds apart. It was discovered by Edward Charles Pickering on August 18, 1882. Image: ESO, 2013. Peering through the thick dust clouds of our galaxys central parts (the bulge) with an amazing amount of detail, a team of astronomers has revealed an unusual mix of stars in the stellar grouping known as Terzan 5. These same colours can be seen in the famous and impressive Ring Nebula (heic1310), a prominent example of a nebula like this one. What it Means to Be a Sagittarius - Keen Articles The Mythology of the Constellations: Sagittarius 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. The stars traditional name, Kaus Australis, comes from the Arabic word for bow (qaws) and the Latin word for southern (australis). NGC 6559, image: Adam Block/Mount Lemmon SkyCenter/University of Arizona (CC BY-SA 3.0 US). Chiron was immortal, so he could not die. 59 Sagittarii (sometimes also known as b Sagittarii) is a K-type bright giant at the southeast corner, about 1,200 light years distant. It is obscured from view by large cosmic dust clouds in the galaxys spiral arms. NGC 6544, 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 proper names of stars that have been officially approved by the International Astronomical Union (IAU) are Ainalrami, Albaldah, Alnasl, Arkab Posterior, Arkab Prior, Ascella, Belel, Gumala, Kaus Australis, Kaus Borealis, Kaus Media, Nunki, Pincoya, Polis, Rukbat, Sika, and Terebellum. The nebula lies at a distance of 6,000 light years from Earth and has an oval diameter of 15 to 22 arcseconds. How to Find the Sagittarius Constellation - ThoughtCo It represents the archer. The star is believed to have a debris disk, like Vega, the brightest star in the constellation Lyra. The Box Nebula, catalogued as NGC 6445, is a planetary nebula with a visual magnitude of 11.2. The gamma ray burst was so powerful that it hit the Earths ionosphere and briefly expanded it. Barnard, who discovered it in 1881 using a six-inch refractor telescope. The cluster was discovered by William Herschel in 1784 using his 18.7-inch telescope. Sagittarius Constellation (the Archer): Stars, Myth, Facts, Location Stellar corpses in this image also emit X-rays as either neutron stars or black holes in binary systems. Alnasl comes from the Arabic al-nal which means arrowhead, and Nushaba is derived from Zujj al-Nashshaba, which means the same thing. The most notable of these regions, the radio-emitting nebula G10.3-0.3, is home to the cluster 1806-20, which contains an O-type supergiant, two blue hypergiants, three Wolf-Rayet stars, the luminous blue variable LBV 1806-20 and the magnetar SGR 1806-20. The companion star has an apparent magnitude of 5.84 and is located about 359 light years from Earth. Being half human aligned the centaur with intellect and civility, while the horse end symbolized. Some of the brightest stars in Sagittarius Delta, Epsilon, Gamma-2, Lambda, Zeta, Phi, Tau and Sigma Sagittarii form an asterism known as the Teapot. The cluster contains 18 RR Lyrae type variable stars. V4641 Sagittarii is the fourth known microquasar, discovered after four of the fastest X-ray intensity changes ever seen from a star. The companion star is more massive than the primary, but so faint that optical telescopes cannot detect it. Sagittarius is a masculine sign and ruled by Jupiter, and is balanced and complemented by the opposite sign of Gemini, ruled by Mercury. Image: NASA/CXC/MIT/F.K.Baganoff et al. Myths of the Constellations Greek Gods & Goddesses It must be observed in infrared wavelengths. Although the centaur was most common in Greek mythology . NGC 6717 is a globular cluster 23,100 light years away. It was first discovered by the French astronomer Guillaume Le Gentil in 1747. The cluster can be seen only 0.8 degrees to the southeast of Delta Sagittarii. Its symbol is . There are no meteor showers associated with the constellation. In English, the constellation is known as the Archer. 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. This cosmic pair is set against millions of glowing stars from the brightest part of the Milky Way a region so dense with stars that barely any dark sky is seen across the picture.This part of the constellation of Sagittarius (The Archer) is one of the richest star fields in the whole sky the Large Sagittarius Star Cloud. NGC 6440 is another globular cluster in Sagittarius. The star is classified as a semiregular variable of the SRc type. The shared birthday is another uncommon property; a large number of globular clusters, both in the Milky Way and in other galaxies, seem to have at least two clearly differentiated generations of stars that were born at different times. It's easy to see why the myths behind Centaurus and Sagittarius often get confused. It contains a young cluster, with an estimated age of 0.6 million years, which has at least four O-type stars and five massive young stellar objects (YSOs). People born under the Zodiac sign of Sagittarius, from November 22 to December 21, are said to be magnetic, passionate, adventurous, and intense, according to Allure perfect traits, in fact, to describe the archer figure that represents them. (In 2003, the Canis Major Dwarf Galaxy was discovered and recognized as the nearest neighbour.). Other than Virgo, the Sagittarius myth is probably the most commonly misinterpreted of all of the constellation myths. It is located only 5.41 light years from Barnards Star in the neighbouring constellation Ophiuchus. The nebula contains an open cluster of 35 hot young stars which illuminate its gases. The signal was received by SETI researcher Dr. Jerry R. Ehman on August 15, 1977 at the Ohio State University. Sagittarius is an astrological sign transitted by the Sun from approximately November 23rd to December 22nd. The cluster spans about 65 light years and occupies about 11 arc minutes of the apparent sky. M22 was originally discovered by the German amateur astronomer Johann Abraham Ihle in 1665. It has an apparent magnitude of 13.5 and can be seen near the star 16 Sagittarii. Eratosthenes argued that the constellation really represented a satyr and not a centaur. Omega Sagittarii is a G-type subgiant marking the northeast corner of the Terebellum, about 78 light years distant from Earth. Astronomers obtained this portrait of Barnards Galaxy using the Wide Field Imager attached to the 2.2-metre MPG/ESO telescope at ESOs La Silla Observatory in northern Chile. Delta Sagittarii has a radius 62 times solar, a mass about five times solar, and is 1180 times more luminous than the Sun. It may look like something from The Lord of the Rings, but this fiery swirl is actually a planetary nebula known as ESO 456-67. Messier 21, Atlas Image mosaic obtained as part of the Two Micron All Sky Survey (2MASS), a joint project of the University of Massachusetts and the Infrared Processing and Analysis Center/California Institute of Technology, funded by the National Aeronautics and Space Administration and the National Science Foundation. The small cluster is only 1 arc minute in diameter. Red Spider Nebula (NGC 6537), image: Judy Schmidt (CC BY 2.0). It is about 15 light years in diameter. Ross 154 was originally catalogued by the American astronomer and physicist Frank Elmore Ross in 1925. It is good to remember the reason why Sagittarius is a centaur in the first place. It is a sparse cluster with an estimated age of only 7.5 billion years. Image: ESA/Hubble and NASA. This striking view of the globular star cluster Messier 55 in the constellation of Sagittarius (the Archer) was obtained in infrared light with the VISTA survey telescope at ESOs Paranal Observatory in Chile. Messier 23 is an open star cluster, discovered by Charles Messier in June 1764. Flower: Carnation Like a carnation, those born under the sign of Sagittarius are strong, yet beautiful. The Sagittarius Myth - The Correct Story Behind The Myth What is the flower of Sagittarius? Zodiac Signs and Greek mythology One of the most well-known aspects of astrology is the connection between the zodiac signs and Greek mythology. The stars agony has culminated in a wonderful planetary nebula known as NGC 6565, a cloud of gas that was ejected from the star after strong stellar winds pushed the stars outer layers away into space. Beta-2 Sagittarii, or Arkab Posterior (because it trails after Beta-1), is a giant star belonging to the spectral type F2III.
