Abstract
A translucent interstellar cloud is one that has visual extinction intermediate between that of a ▶ diffuse cloud and that of a dense ▶molecular cloud. Despite the importance of photochemical processes over much of their extent, translucent clouds contain significant molecular column densities. Translucent clouds can be studied both in molecular absorption and emission lines. This term is also used to describe lines of sight through the diffuse edges of dense clouds.
