Explanation:
Sometimes even the dark dust of interstellar space has a serene beauty.
One such place occurs toward the constellation of Taurus.
The
filaments featured here can be found
on the
sky between the
Pleiades star cluster and the
California Nebula.
This dust is not known not for its bright glow but for its absorption and opaqueness.
Several bright stars are visible with their blue light seen
reflecting off the brown dust.
Other stars appear unusually red as their light barely peaks through a column of dark
dust,
with red the color that remains after the
blue is scattered away.
Yet other stars are behind dust pillars so thick they
are not visible here.
Although appearing serene, the scene is actually an ongoing loop of tumult and rebirth.
This is because massive enough knots of gas and dust will
gravitationally collapse
to form new stars -- stars that both
create new
dust
in their atmospheres and destroy old dust with their energetic light and
winds.
