Dark Nebula

A dense cloud of interstellar dust so opaque that it blots out the light of the stars and glowing gas behind it, appearing as a dark silhouette. Catalogued systematically by E. E. Barnard, dark nebulae are the cold, dusty reservoirs — often molecular clouds — from which new stars condense.

Highlights

  • Opaque dust silhouetted against the light behind it
