SH2-136 Ghost of Cepheus
SH2-136 taken on November 20th, 2014 is a reflection nebula in Cepheus. The nebula is made up of dark regions opaque to visible light from the background stars consisting of dense and very cold clouds of gas, molecular hydrogen, and dust. Bok globule, as they are called (named after Dr. Bart Jan Bok), are star forming regions — typically containing less than 100 solar-masses of material. The stars buried within the bok globule are protected from having their hydrogen envelopes stripped by the stellar winds of nearby companions.They will emerge from their stellar cocoons once the stars progress enough to develop their own stellar winds to evaporate the globule.
