Debunking the Zodiac Myth in 60 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. 62 Sagittarii (or c Sagittarii) is an M-type giant at the southwest corner, about 450 light years from Earth. 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. The Sagittarius Dwarf is believed to already have orbited the Milky Way about 10 times in the last billion years or so, and it still appears to have coherence as an elongated ellipse despite being torn apart by enormous tidal forces as a result of the interaction. NGC 6723 is a globular star cluster in Sagittarius, near the border with Corona Australis. This, however, only applies to Mars and it happens very rarely. At the time, it was believed to be a magnitude 11.4 slow nova as it had not been visible in older images of the region and only appeared to brighten in the previous couple of years. The clusters small central region has one of the highest star densities in the Milky Way. 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. 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. Sagittarius A* is the leading candidate for the location of the supermassive black hole believed to be at the centre of the Milky Way Galaxy. It's just a matter of which stars you think go with which other ones. The cluster can be seen only 0.8 degrees to the southeast of Delta Sagittarii. Like other zodiac constellations, Sagittarius was first catalogued by the Greek astronomer Ptolemy in the 2nd century. 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. The Sagittarius Dwarf Irregular Galaxy contains mainly intermediate-age stars as a result of a prolonged period of star formation. This Chandra image of Sgr A* and the surrounding region was made from a 164 hours of observation time over a two-week period. Flower: Carnation Like a carnation, those born under the sign of Sagittarius are strong, yet beautiful. At the centre of the Lagoon Nebula, there is a structure known as the Hourglass Nebula (not the same object as the famous Hourglass Nebula, which is located in the constellation Musca). 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. A transiting planet was spotted orbiting the magnitude 16 eclipsing variable star OGLE-TR-10 (G2V) in 2002. 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.

Globular clusters are dense collections of old stars. What is the flower of Sagittarius? Instead, Sagittarius is thought to represent Crotus, a satyr who invented the archer's bow. It was discovered by Italian astronomer Giovanni Battista Hodierna in 1654. They orbit each other with a period of 241.5 days and are separated by only 2 astronomical units. The cluster was discovered by William Herschel in 1784. It's easy to see why the myths behind Centaurus and Sagittarius often get confused. With a mass of 10,000 solar masses, it is about 10 times more massive than typical open clusters in the Milky Way. Sagittarius, the half human and half horse, is the centaur of mythology, the learned healer whose higher intelligence forms a bridge between Earth and Heaven. 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. 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. PSR J1748-2446ad was discovered on 10 November, 2004. At the time, Sag DEG was the nearest known neighbouring galaxy of the Milky Way. Sagittarius - The Myth Story of Sagittarius - findyourfate.com Image: ESA/Hubble & NASA. Because he was close to the Muses, they were the ones who asked Zeus to place him in the sky. The star is believed to have a debris disk, like Vega, the brightest star in the constellation Lyra. The glyph is the upward-pointing arrow of the archer, ready to be fired into the future. It has a mass three million times that of the Sun. 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. Alternatively, some mythology identifies Sagittarius as the son of Pan, the god who created archery. Messier 28, 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).

Even though Chiron was skilled in medicine, he also could not heal himself, putting him in great pain. Some explanations suggest that there is something different about clusters that form within dwarf galaxies, giving them a different composition. 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.. It lasted for full 72 seconds, but has never been detected since. Sagittarius symbolism and mythology. Myths of the Constellations Greek Gods & Goddesses Alpha Sagittarii shares its traditional name, Rukbat, with the star Delta Cassiopeiae (now formally known as Ruchbah). The cluster is located at a distance of 75,700 light years from Earth. Crotus, much like Chiron, was a skilled musician and hunter. The cluster occupies an area of 2 of apparent sky.

The complex of star forming regions is obscured by interstellar dust, but it can be observed in radio, infrared and X-ray bands. It is approximately 96.1 light years distant. It contains very few variable stars. KW Sagittarii is one of the largest known stars. Sagittarius is the 15th largest constellation in the sky. Image: U Harvard. Its name means divided into three lobes. Sagittarius was characterized in mythology as being unrestrained as wild or untamed horses despite their human head, arms, and torso. M22 was originally discovered by the German amateur astronomer Johann Abraham Ihle in 1665. 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. Sagittarius constellation, Baades Window and the Teapot, photo: NASA, ESA, Z. Levay (STScI) and A. Fujii.

Artist conception of the December 27, 2004 gamma ray flare expanding from SGR 1806-20. The galaxy was named after the American astronomer E.E. Before being assigned to Sagittarius, the star system was known as Beta Telescopii. The cluster was first observed by Charles Messier in June 1764. They guard their hearts carefully because they are highly sensitive individuals that fear being hurt. 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 stars traditional name, Kaus Australis, comes from the Arabic word for bow (qaws) and the Latin word for southern (australis). The nebula was discovered by Edward Charles Pickering on July 15, 1882. The cluster was discovered by Charles Messier in 1778. In mythology, Centaurs were hard drinkers, unreliable, misleading, crude, wild, and adulterous. The cluster is so sparse that it was once considered to be an asterism. During this time the black hole flared up in X-ray intensity half a dozen or more times. The globular cluster Messier 54 lies at the core of the galaxy. Sometimes it is also called the Sagittarius I Dwarf or Sagittarius Dwarf Spheroidal. It is one of only four star systems known to be hydrogen-deficient, which makes it difficult to classify U Sgr. The symbol of the Sagittarius is the centaur, a half-man and half-horse being from Greek mythology, or more generally, the archeras the centaur is typically . It is one of the several notable H II regions in Sagittarius. It cannot be seen visually, but must be observed in radio, X-ray and infrared bands. Whether you think Sagittarius is based on Chiron or Crotus doesn't really matter, I suppose. Sagittarius is Latin for "archer," and since ancient times the constellation has been represented as a creature wielding a bow and arrow. The brightest stars in the cluster are 16th magnitude. (In 2003, the Canis Major Dwarf Galaxy was discovered and recognized as the nearest neighbour.). It will make its closest approach to the Sun in about 150,000 years, when it comes within 6.13 light years of our solar system. The brightest one has a magnitude of 9.2. The Sagittarius Dwarf Galaxy is an old galaxy, composed mainly of Population II stars (old, metal-poor stars). The cluster was discovered by William Herschel on May 24, 1784. NGC 6528 is another globular cluster, located just to the southwest of NGC 6522. Also discovered were more than two thousand other X-ray sources and huge lobes of 20 million-degree Centigrade gas (the red loops in the image at approximately the 2 oclock and 7 oclock positions). It seems that this cluster has already been kidnapped from its former home and now is part of our own galaxy. 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. NGC 6717 is a globular cluster 23,100 light years away.
