He actually searched for comets and to avoid confusion between comets and Messier objects, he and his colleagues compiled them in a list in 1771. It was a remarkable achievement. The list 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 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 are located in the constellation of Scorpius. The Butterfly Cluster is Messier 6. This object can be seen by telescope clearly, and in the grayish color by naked eye. The Butterfly Cluster existence was first noticed by Giovanni Battista Hoderna in 1654. Ptolemy discovered it while he was observing M7, and declared it as a part 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 butterfly with open wings and antennae. The stars of the cluster twinkle, and it looks very beautiful in the sky. It is visually a very rewarding 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 magnitude of 4.2, an angular diameter of 25 arc minutes, and lies at a distance of 1,600 light years with a luminosity of 8,300 suns. The Butterfly Cluster is about 50 million years old and can be seen in summer nights clearly with binoculars. The objects (M6 and M7) are the summer’s finest and brightest clusters. Different astronomers have different opinions about M6’s 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 Summer Chart” are clearly visible on summer nights. Messier objects help astronomers to adjust the distance scale 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 patch 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 two 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 three bright stars in the butterfly’s body. The Butterfly Cluster contains almost 80 stars (Plotner 400) with B type blue (hottest) and K type orange stars (BM Scorpii, HD 160371). The brightest K type orange star is a semi-regular
Our galaxy contains nearly 400 billion stars including many comets, nebulas and star clusters. Star clusters, or Messier objects, are collections of many stars in our galaxy…
Although Charles did not participate directly he was charged for conspiring with the Manson family leading to the deaths in the joint responsibility rule. However, looking at Manson biography we find that Manson was a troubled young person right from early childhood.
It is characterized into many different forms which are discussed below.
This is used in the making of educational plans and programs to cover a wider breath of subjects and topics. It contributes positively to the relationship of the main educational institutions like the further and higher institutions.
This technique is basically used for segmentation.
The respondents can be classified the various clusters on the basis of the importance they give to various facilities provided. The clustering methods are simple procedure and are based on algorithms. It is not based on statistical reasoning.
Butterfly was indentified to be a significant symbol for civilization through a research by Donald Lipski, thereby signifying a sense of rejuvenation, reincarnation and love. The art was created through an arrangement of approximately 10,000 test tubes filled with
The paper gives detailed information on the play M. Butterfly. The play portrays the “present day” France (The play was written in the late 1980s.). In the opening scene of the play the central character Gallimard addresses the readers and narrates his story in a flashback. The dramatist brings the readers back to Beijing in the 1960s and 1970s through the memories of Gallimard, an old man of 65 years.
It startles how Gallimard remained in an affair with Liling for twenty years without realizing his real gender. Gallimard is like a butterfly that dons at every blossoming flower oblivious of the nature if such flowers. In essence, his love for the East
