The dark spots in the picture are not photographic defects but an unusual type of interstellar cloud known as a Bok globule. Bok globules, named after astronomer Bart Bok who studied them extensively, are small dark clouds made of gas and dust that are typically condensing to form a star or stars. These Bok globules are located at a distance of about 6000 light years near IC 2944 cluster in the emission nebula IC 2948.
