M16, aka NGC 6611, aka
the Eagle Nebula, is in
Serpens, near the borders
between Serpens, Scutum,
and Sagittarius, and about
8000 lightyears distant. As
you gaze upon the Eagle,
you are witnessing the birth
of new suns -- their energy
causing the surrounding
gases to glow. Compare
with other stellar nurseries,
such as
M42 and M20.
