Head of Column No. 4 in Eagle Nebula
Enlarged view of the head of Column 4 in the Eagle Nebula. This column is similar to the more familiar ones, but thus far less impacted by the massive stars in NGC6611. The two red nebulosities in the head signpost one or more young stars so deeply embedded that they cannot be seen directly in the VLT infrared image, only indirectly as they illuminate dust around them. One of these sources is thought to be the origin of the Herbig-Haro object HH216 seen in ESO Press Photo eso0142a and ESO Press Photo eso0142b.
Technical information: The region shown measures 1.9 x 2.8 light-years (0.6 x 0.9 pc). The intensity scalings have been adjusted to better show the young stars embedded in the head of each column. North is up and East left.
