Cosmic Glitter in the Coalsack

Cosmic Glitter in the Coalsack
The protoplanetary phase
of nebulae sidereal
occurs in astral later days
before the stage ethereal
when cloud impressions like Monets
create new star material.
At edge of inky Coalsack cloud,
nebula Caldwell Ninety-nine,
amidst the murk of dusty shroud,
PPN stellar redesign
with brilliance beauteous endowed
near verge of Coalsack’s borderline
was seen by Hubble shining bright
as thrust through atramentous dark
in cryptic interstellar sleight
of hand by cosmic Matriarch,
who lavishes great Nature’s light
of vital sun with living spark.
Our Mother Earth her watch shall keep
o’er woodlands wild and oceans deep
the river vales and mountains steep,
o’er stately swans and eagles’ sweep.
The laughing brooks on hillsides leap,
though loons lament while willows weep.
Still humankind seems sound asleep
to deeds they sow and what they’ll reap.
Yet mindless soils of mires and mucks
can sprout a forget-me-not plot,
as in the constellation Crux
that PPN midst sooty spot
is blossoming per starry flux
from out the caliginous clot.
This vision in our Milky Way,
might it portend scenario
of what in years, some millions, may
be future for the Coalsack’s woe
of present dark, when stardust stray
will coalesce and set aglow
with brightness all the ‘nuggets coal’
in ebon Coalsack, so they flare
from gravity’s attractive role
in grand combustions here and there,
as if were touched by flame the whole
until illumined everywhere?

Explanation: This stunning image captures a small region on the edge of the inky Coalsack Nebula, or Caldwell 99. Caldwell 99 is a dark nebula — a dense cloud of interstellar dust that completely blocks out visible wavelengths of light from objects behind it. The object at the center of the image is a (much smaller) protoplanetary nebula. The protoplanetary nebula (PPN) phase is a late stage in the life of a star in which it has ejected a shell of hydrogen gas and is quickly heating up. This stage only lasts for a few thousand years before the protoplanetary nebula’s central star reaches roughly 30,000 Kelvin. At this point, the central star is producing enough energy to make its surrounding shell of gas glow, becoming what’s known as a planetary nebula. The observations that comprise this image were made using Hubble’s Advanced Camera for Surveys in visible and infrared wavelengths. Astronomers took these observations to learn more about the evolution of protoplanetary nebulae into planetary nebulae.
