Meanwhile, Within the Pillars of Creation

Tucked invisibly away with the constellation Serpens the Serpent and
located nearly 7,000 light years from Terra Firma, one encounters the
stunningly gorgeous towers of furious star birth known colloquially -and to
the consternation of atheists- as "the Pillars of Creation." Before we
continue this tiresome diatribe, let's simply take a look:

[image: Pillars_of_Creation_(NIRCam_Image).png]

Behold the "Pillars of Creation," located within the "Star Queen" Nebula,"
or, more prosaically, the "Eagle Nebula," known to the astronomical
cognoscenti  as Messier 16 and to the soul-dead celestial actuaries as NGC
6611.    Spanning tens of light years,these pillars are gaseous clouds from
which numerous stars are taking form.  These young stars then impart high
energy radiation into its surroundings, which causes the gases to floresce*
and eventually dissipate.

The above image was captured by the James Webb Space Telescope, the
outer-space observatory that has become so wildly successful so quickly
that the world has been left to furrow its brow and ask "Hubble Who?"
 Unlike  previous  snaps, this one was taken in near infrared and so
enables us to observe some of star birth cauldrons that had hitherto been
concealed by  the intervening gases.    Astronomers can now directly study
some of the complex processes involved in star formation.    As such
formation generally requires approximately 10 million years, scientists are
only able to scrutinize a few of the stages.  However, these observations
still enable stellar astronomers to construct detailed models related to
the entire sequence of events involved in making a star.

We should take time to admire the Pillars of Creation now, as this
structure is doomed.    Images captured by the Spitzer Space Telescope have
shown a nearby hot dust cloud believed to be the remnants of  supernova,
the blast from which likely evaporated the pillars approximately 6,000
years ago.   Since these pillars are 7,000  light years from Earth,
information related to that destruction hasn't yet reached us, but will in
about 1,000 years!

So, the Pillars of Creation no longer exist.   We're merely admiring its
ghost.


*Florescence:   the gases absorb high energy radiation and then re-radiate
it as visible light.   The glow is therefore generated by the nebula's
constituent gases, as opposed to  a reflection nebula, in which the gas
merely reflects the light of stars embedded within it.
