An intriguing and beautiful nebula,
NGC 3576
drifts through the Sagittarius arm of our spiral
Milky Way Galaxy.
Within the region,
episodes
of star formation are thought to contribute
to the complex and suggestive shapes.
Powerful winds from the nebula's embedded,
young,
massive stars shape the looping filaments.
The dramatic
false-color
image also highlights the
contributions of hydrogen, sulfur, and oxygen, energized by
intense ultraviolet radiation, to the nebular glow.
But the glow also
silhouettes dense clouds of dust
and gas.
For
example, the two condensing dark clouds near the
top of the picture offer potential sites for the formation
of new stars.
NGC 3576 itself is about 100 light-years across and
9,000 light-years away in the southern
constellation of Carina, not far on the sky from the famous
Eta Carinae Nebula.
Near the left edge of the picture is NGC 3603, a much larger
but more distant
star
forming region.
