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.
