Coalsack

molecular cloud, also called dark nebula, interstellar clump or cloud that is opaque because of its internal dust grains. The form of such dark clouds is very irregular: they have no clearly defined outer boundaries and sometimes take on convoluted serpentine shapes because of turbulence. The largest molecular clouds are visible to the naked eye, appearing as dark patches against the brighter background of the Milky Way Galaxy. An example is the Coalsack in the southern sky. Stars are born within molecular clouds.
