In today's image, we see an example of a dark nebula. This is a concentration of dust in a molecular cloud and is often associated with star formation. If the dust is dense enough, it will completely block out the light of stars behind the cloud. In regions where the dust is not as dense, it will dim and redden the light from the stars.
