  What it is

vdB-141 is alarge cloud of dust and molecular gas in our Milky Way galaxy. It appears to have the ghostly image because of the stars that are embedded inside it and which may have been born there. The unusual miniature ghosts have been shaped by radiation erosion of the edges of the cloud by nearby stars.
