The Dark River to Antares

A dark river seems to flow through this sky, from the horizon toward colorful clouds near the red giant star Antares. This murky river is a dusty nebula obscuring background starlight near the central Milky Way. The dark dust nebula contains mostly hydrogen molecular gas. Dust scattering starlight around Antares, the alpha star of Scorpius, creates the yellow-hued reflection nebula.
