Text adapted from APOD: An intriguing and beautiful nebula, NGC 3576
(right) 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 image also highlights the contribution of
hydrogen, 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 nebula 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. On the
left of the picture is NGC 3603, a much larger but more distant star forming region.
