Explanation:
It's stars versus dust in the Carina Nebula and the stars are winning.
More precisely, the
energetic light and
winds
from massive newly formed
stars are evaporating and dispersing the
dusty stellar nurseries in which they formed.
Located in the
Carina Nebula and inside a region
known informally as
Mystic Mountain,
these pillars' appearance is dominated by opaque brown dust
even though it is composed mostly of clear
hydrogen gas.
Even though some of the
dust pillars look like
torches,
their ends are not on
fire -- rather, they are illuminated by nearby stars.
About 7,500 light-years distant, the featured image was taken with the
Hubble Space Telescope and highlights
an interior region of Carina known as
HH1066
which spans nearly a
light year.
Within a few million years, the stars will likely
win
out completely and the dust torches will completely
evaporate.
