Notes
NGC 3576 is a large emission nebula located in the constellation Carina.  It spans about 100 light-years across and lies at a distance of 9000 light-years from Earth.  NGC 3576 is less than 4° from its larger and more spectacular neighbor, Eta Carina, which is also located at a similar distance.  Violent winds from massive Wolf-Rayet stars have sculpted the delicate arches of NGC 3576 seen in the above image.  Bok globules, dense clouds of opaque gas and dust, are scattered throughout and represent regions of new star formation.

At the left of the image is NGC 3603, another HII region much larger than NGC 3576 and lying at nearly twice the distance.  These two nebula as well as Eta Carina, all located within the Sagittarius arm of the Milky Way galaxy, form a huge expanse where the inexorable forces of nature are forging stellar creation on a massive scale.
