This COMPTEL all-sky map of gamma rays in the 1-30 MeV energy range represents 
the results of the first-ever survey of the Universe at these energies.  The 
concentration of the emission along the Galactic plane is the most striking 
aspect of the map.  The plane stands out clearly against the rest of the sky, 
indicating that most of the measured gamma-ray fluxes come from regions or 
objects inside the Galaxy.
