Now that things have calmed down post-holiday craziness, here's the answer to a question that I posed a couple of weeks ago: Where did the 37 Cluster get its name? Swipe to the second image to find out! #37cluster #37 #opencluster #starcluster #stars #gravitationallyboundbitsofbabyplasma #asterism #pareidolia #ngc2169 #in #orion #constellation #oriontelescopes #xt8 #pixel2 #nightsight #cellphoneastrophotography #space #amateurastronomy #observing #astronomy #astronomynerd #astro #sky #backyardtelescope #lostinspace #night #nightsky #stargazer #standingbehindaneyepieceholdingyourbreath https://www.instagram.com/p/BsZUe9_FBBD/?utm_source=ig_tumblr_share&igshid=103f9ddptflq7

Portrait of NGC 281 via #NASA #APOD Astronomy Picture Of the Day https://buff.ly/2kdQ6OS⠀ ⠀ Look through the cosmic cloud cataloged as #NGC 281 and you might miss the stars of #opencluster IC 1590. Still, formed within the #nebula that cluster's young, #massivestars ultimately power the pervasive nebular glow. The eye-catching shapes looming in this portrait of #NGC281 are sculpted columns and dense dust globules seen in silhouette, eroded by intense, energetic winds and radiation from the hot cluster stars. If they survive long enough, the dusty structures could also be sites of future #starformation. Playfully called the #PacmanNebula because of its overall shape, NGC 281 is about 10,000 #lightyears away in the #constellation #Cassiopeia. This sharp composite image was made through narrow-band filters, combining #emission from the nebula's #hydrogen, #sulfur, and #oxygen atoms in #green, #red, and #blue hues. It spans over 80 light-years at the estimated distance of NGC 281.

"In astronomy, the Pleiades or Seven Sisters (Messier 45 or M45), is an open star cluster located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky."

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 11, um aglomerado aberto na constelação de Scutum (o escudo). M 11 é conhecido também como o aglomerado do Pato Selvagem. 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 11, a open cluster in the constellation of Scutum (the shield). M 11 is also known as 'The Wild Duck' cluster.
