A New Shape Model of the Homunculus Nebula (image) NASA/Goddard Space Flight Center Share Print E-Mail Caption A new shape model of the Homunculus Nebula reveals protrusions, trenches, holes and irregularities in its molecular hydrogen emission. The protrusions appear near a dust skirt seen at the nebula's center in visible light (inset) but not found in this study, so they constitute different structures.
