Description

The Eagle Nebula (also known as M 16 or NGC 6611) is a large H II region visible in the Serpent Tail constellation; it is formed by a young open cluster of stars associated with an emission nebula composed of ionized hydrogen, cataloged as IC 4703. [1]

Its distance has always been relatively uncertain, but we tend to accept a value of about 7000 light years from the Earth, thus placing it in the middle area of ​​the Sagittarius Arm; contains some extremely well-known formations, such as the Pillars of Creation, the long columns of dark gas originating from the action of the stellar wind of the components of the central cluster [4] and which are also responsible for the proper name of the nebula itself, due to their form. In them there are some young stellar objects, which testify that the processes of star formation are still in progress, [5] even if it is not clear whether these are favored or opposed by the action of the stellar wind of nearby stars, nor is it clear whether the wind actually affects these phenomena in some way. [4] The cluster is composed of a large number of very hot and bright blue supergiants; their typical age is just 2-3 million years, [2] that is less than one thousandth of the age of our Sun; the brightest star in the cluster is of magnitude 8.24, [6] clearly visible even with binoculars.

The nebula has been known since the eighteenth century and is one of the best known objects among those in the Messier Catalog; it reveals itself easily in photographs and is therefore a good subject for amateur astrophotography enthusiasts. font. Wikipedia
