Description

Down in the Cepheus molecular complex, there is this dark nebula. Its elongated shape is due to the interaction with the bubble of a supernovae explosion.
The red stains inside the darkest part of the nebulae are Herbig-Haro objects caused by new born stars forming. New worlds are going to rise there.
