Open star cluster M16 has formed from this great gaseous and dusty cloud, the diffuse Eagle Nebula IC 4703, which is now caused to shine by emission light, excited by the high-energy radiation of its massive hot, young stars.
A deeper insight in the star formation process could be obtained from the HST images of M16, published in November 1995; moreover, they were used for an animation simulating the approach to this star forming region, and we provide some screen sized images (suitable as backgrounds for your computer screen).
M16 is found rather easily, either by locating the star Gamma Scuti, a white giant star of magnitude 4.70 and spectral type A2 III, e.g.
The M16 is a lightweight, 5.56 mm caliber, air-cooled, gas-operated, magazine-fed rifle, with a rotating bolt, actuated by direct impingement gas operation.
Replacement of the M16 family has been proposed at various points, and its longevity is in part due to a series of delays and failures in projects meant to replace it.
The M16 utilizes direct impingement gas operation; energy from high-pressure gas tapped from a port built into the front sight assembly actuates the moving parts in the weapon.
