The Large Magellanic Cloud in Infrared

Where does dust collect in galaxies?

To help find out, a
team of researchers took the most detailed image ever of gas clouds and
dust in the neighboring
Large Magellanic Cloud (LMC) galaxy.

The composite image,
shown above, was taken by the
Spitzer Space Telescope in
infrared light,
which highlights the natural glow of the warm materials returned to the
interstellar medium by stars.

The above mosaic combines 300,000 individual pointings to
create a composite 1,000-times sharper than any previous LMC image.

Visible are vast clouds of gas and
showing in graphic detail that dust prefers regions near young stars (red-tinted bright clouds), scattered unevenly between the stars (green-tinted clouds),
and in shells around old stars (small red dots).

Also visible are
huge caverns cleared away by the
energetic outflows of massive former stars.

The faint blue (false-color) glow across the bottom is the combined light from the old stars in the
central bar of the LMC.

The LMC is a
satellite galaxy to our own
Milky Way Galaxy, spans about 70,000
light years,
and lies about 160,000 light years away toward the southern constellation of the
