M16 (NGC6611) is a magnificent diffused nebula in the constellation of Serpens, with a size of 30 arc minutes and a distance of about 4600 light years.
The nebula is lying on top of an open cluster, both nebula and cluster have same number of M16=NGC6611.
The nebula has a nickname "Eagle Nebula", very luminous with dark streaks of dust; a nursery of baby stars.
The dark streaks, which look like elephant's nose, are now very popular by a very clear photograph taken by the Hubble Space Telescope (HST).
A magnified image below shows you the central region of the Eagle Nebula.
This image barely captured the gaseous pillars like the HST's one.
