This is by far one of my favorite APOD pictures EVER. I love it because the shade of blue of the sky, and the way the stars look picture perfect. But mostly because the gas clouds look like dogs! Or wolves! It's so beautiful I can't deal. But it's also very fascinating, because although the clouds look very thick, especially towards the center, they are not. The clouds are relatively thin, it is only because of the interstellar dust that the clouds look opaque at all. What's happening though, is the stars we see are emitting energetic light and wind after they formed, and dispersing the clouds, or stellar nurseries from which they formed. It is predicted that within the next few million years, the stars will completely defeat the clouds and they will disappear all together.
