coalsack dark nebula

The sky near the southern celestial pole, including the constellation Crux and the Coalsack Dark Nebula. The southern sky contains many more dark nebulae visible against the Milky Way than the northern sky, and the astronomies of southern cultures often figure these dark nebulae prominently as their figures in the night sky. In Australian Aboriginal astronomy, the Coalsack was the head of the Emu in the sky, and in Incan astronomy, it was the Yulu, or partridge.
