This complex and beautiful star-forming region in the constellation Carina consists of two separate NGC numbers, 3576 for the right-hand part, which resembles the Statue of Liberty (hence the common name), and 3603 for the somewhat different-looking nebulosity on the left side. The small knot of nebulosity at lower left is GN 11.14.4.
It is currently thought that the two large nebulae are separate nebulae lying at different distances, which is consistent when their differing appearance. NGC 3603 on the left is known to be the most massive H-II region in the Milky Way, and the small bright cluster at its bottom right, which is responsible for energizing the whole nebula, is the densest known group of massive stars in our galaxy.
