NGC 3586
NGC 3576 is a bright emission nebula in the Sagittarius arm of the galaxy a few thousand light-years away from the Eta Carina Nebula (NGC 3372). It is approximately 100 light years across and 9000 light-years away from Earth. This nebula even received six different classification numbers (NGC 3576, 3579, 3581, 3582, 3584 and 3586). Currently, astronomers call the entire nebula NGC 3576. NGC 3576 was discovered by John Frederick William Herschel on 16 March 1834.
A popular nickname is "The Statue of Liberty Nebula" because of the distinctive shape in the middle of the nebula. The name was first suggested in 2009 by Dr. Steve Mazlin, a member of Star Shadows Remote Observatory (SSRO). Within the nebula, 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. See Wikipedia for more details.
To the left of NGC 3586 lies NGC 3603, a massive HII region containing a very compact open cluster (probably a super star cluster) HD 97950. See Wikipedia for more details.
