I’m astounded at the level of detail in the gas clouds surrounding NGC 3603 and NGC 3576 and their gentle interplay among the surrounding sea of stars I was able to capture in this image. The Hydrogen-rich clouds (pictured in blue) stretch across the whole field of view with the secondary emission being the orange-brown folds of Sulphur. Dark dust regions obscure the view around the glowing star factory in the middle.
