Charles Messiers Butterfly clunk - evidence ExampleHe actually searched for comets and to avoid confusion in the midst of comets and Messier objects, he and his colleagues compiled them in a contention in 1771. It was a remarkable achievement. The add up is known as the Messier Catalog or Messier Object List. The list contains a total of 110 objects. The list contains nebulae, galaxies and star clusters. Body During the process of these observations, the first object they observed was the Crab Nebula (M1). A total of 103 objects were listed by Messier and his colleagues (Burnham 73). The Crab Nebula is a ball of gas left all over from a supernova explosion. M2 is a globular cluster of stars in Aquarius, M3 is located in Canes Venatici, and Messier 4 to Messier 7 be located in the constellation of Scorpius. The Butterfly Cluster is Messier 6. This object can be seen by orbit clearly, and in the grayish color by naked eye. The Butterfly Cluster existence was first find by Gi ovanni Battista Hoderna in 1654. Ptolemy discovered it while he was observing M7, and declared it as a classify of M7. After that, Phillips Loys de Cheseaux (1945-1946) observed it and recognized it as a very fine star cluster. And finally it was catalogued by Charles Messier in 1764 in the list of Messier objects (The Griffith Observer 259). The Butterfly Cluster is an open cluster of stars in the constellation of Scorpius known as Messier 6 or the Butterfly Cluster as it resembles a flying squash with open wings and antennae. The stars of the cluster twinkle, and it looks very beautiful in the sky. It is visually a very honour object the butterfly pattern is very visible and obvious. It has been placed in the 6th position in the list of Messier objects. Scorpio is located in the Milky Way and contains many massive objects other than M6 and Messier 7. The Butterfly Cluster has a order of magnitude of 4.2, an angular diameter of 25 arc minutes, and lies at a distance of 1,600 sp rightly years with a luminosity of 8,300 suns. The Butterfly Cluster is about 50 million years grey-headed and can be seen in summer nights clearly with binoculars. The objects (M6 and M7) are the summers finest and brightest clusters. Different astronomers take on different opinions about M6s age. According to Burnham, it is 100 million years old WEBDA estimates its age to be around 95 million years, and 51 million years according to the Sky Catalogue 2000.0. Messier objects of the Messier pass Chart are clearly visible on summer nights. Messier objects help astronomers to adjust the distance outdo of the universe. The above image shows the view of M6 (outcropped). The image was taken through the Astrograph, Takahashi E-180. How Can It Be Seen? It can be seen about 3/ 1-2 degrees northwest of M7 which is located near the tail of Scorpius. It appears as a hazy speckle in the dark sky but it should not be confused with Messier 7. Messier 7 is brighter than Messier 6. M7 is seen in between and the Butterfly Cluster is on its lower side. Messier 6 contains many other Messier objects such as M21, M23, NGC 6167, and NGC 6193. Its magnitude is fainter than M7, and fills the field of 25 angular diameter. One of the ways to find the Butterfly Cluster is to identify the devil well-known asterisms of Scorpios and Sagittarius. It has two irregular loops of blue and white stars on both wings and at 40-50x, it has third bright stars in the butterflys body. The Butterfly Cluster contains almost 80 stars (Plotner 400) with B cause blue (hottest) and K type orange stars (BM Scorpii, HD 160371). The brightest K type orange star is a semi-regular
