Nebula, M16, inspires us like perhaps no other object
in the sky. Perhaps it's because of the beautiful
representation of its namesake, the Eagle. But
more than that, it's a spectacular representation of
creation in real-time. The hot emission nebula
is the birthplace of many hot, new stars. And
it's this aspect of M16 that is captured in the famous
Hubble shot entitled "Pillars of Creation."
Remarkably, amateur scopes can bring these foundational
elements of the nebula up close and personal.
speaking, M16 is a relatively easy object to see
in dark skies. In fact, it will appear as a bright
patch to the naked eye amidst the surrounding summer
Milky Way. However, the pillars themselves are
a little more difficult to see. Regardless,
it is in one of the heaven's most exciting regions of
the sky, and this image merely hints as to its
