Globular clusters: Messier 3, Messier 9 and Messier 15

A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers.

The first known globular cluster, now called M22, was discovered in 1665 by Abraham Ihle, a German amateur astronomer.However, given the small aperture of early telescopes, individual stars within a globular cluster were not resolved until Charles Messier observed M4 in 1764.

딥스카이 중 메시에 3(M3). 태풍급으로 불어대는 강풍속에서 찍은 녀석이라 저따구(?)로 밖에 안나옴. 다시 찍어보리라 맘 먹고 있지만... 언제 다시 찍어볼지는... #M3 #Messier3 #eq6pro #deepsky

O Catálogo de Messier é um conjunto de mais de 100 objetos astronômicos primeiro listada pelo astrônomo francês Charles Messier em 1771. Messier era um caçador de cometas que ficava frustrado por se confundir com objetos que não eram cometas, resolvendo então compilar uma lista deles com a colaboração de seu assistente Pierre Méchain, para evitar perder tempo com eles. O número de objetos do catálogo chegou a 103 durante sua vida, mas alguns mais atribuídos a Messier foram incluídos por outros astrônomos ao longo dos anos. O Catálogo de Messier inclui quase todos os tipos de de objetos de céu profundo - nebulosas difusas, nebulosas planetárias, aglomerados abertos, aglomerados globulares e galáxias. Uma vez que esse objetos podem ser reconhecidos visualmente, eles estão entre os objetos mais brilhantes e, portanto, mais atrativos observáveis mesmo a partir de grandes cidades. O objeto Messier de hoje é M 3, um aglomerado globular na constelação dos Cães de Caça. The Messier Catalogue are a set of over 100 astronomical objects first listed by French astronomer Charles Messier in 1771. Messier was a comet hunter, and was frustrated by objects which resembled but were not comets, so he compiled a list of them, in collaboration with his assistant Pierre Méchain, to avoid wasting time on them. The number of objects in the catalog reached 103 during his lifetime but a few more thought to have been observed by Messier have been added by other astronomers over the years. The Messier catalogue comprises nearly all the most spectacular examples of the five types of deep sky object – diffuse nebulae, planetary nebulae, open clusters, globular clusters and galaxies. Since these objects can be observed visually, they are among the brightest and therefore most attractive observable even from large cities. Today's Messier object is M 3, a globular cluster in the constellation of Canes Venatici (the hunting dogs).
