shapes the remarkable dust tapestry of the nearby Milky Way Galaxy?
No one knows for sure. The intricate structures, shown
were resolved in new detail recently in a wide region of the sky imaged
in far infrared light by the
image is a digital fusion of
three infrared colors: two taken at high resolution by Planck, while
the other is an
image taken by the now defunct
At these colors, the sky is dominated by the faint
glow of very cold gas within only 500
years of Earth.
In the above
image, red corresponds to
temperatures as cold as 10 degrees
above absolute zero, while white corresponds to gas as warm at 40
The pink band across the lower part of the image is warm gas confined
of our Galaxy.
The bright regions typically hold dense
clouds that are
slowly collapsing to form stars,
whereas the dimmer regions are most
interstellar gas and
Why these regions have
filamentary shapes shared on
both large and small scales remains a topic of research.
Future study of the origin and evolution of dust may help in the
history of our Galaxy as well as
such as our Solar System
to be born.
