dark nebula

(absorption nebula, dark cloud)
(cloud that obscures stars behind it)

The term dark nebula is used for a cloud (i.e., nebula) that is dense enough to obscure EMR from behind, which can result in a portion of the sky showing no stars. The extinction can be from dust or dense gas or a combination, often star-forming regions. Radio and infrared are used to view what is inside and behind. An example is LDN 1689.
