<P> A lenticular galaxy is a type of galaxy intermediate between an elliptical and a spiral galaxy in galaxy morphological classification schemes . Lenticular galaxies are disc galaxies ( like spiral galaxies ) that have used up or lost most of their interstellar matter and therefore have very little ongoing star formation . They may , however , retain significant dust in their disks . As a result , they consist mainly of aging stars ( like elliptical galaxies ) . Because of their ill - defined spiral arms , if they are inclined face - on it is often difficult to distinguish between them and elliptical galaxies . Despite the morphological differences , lenticular and elliptical galaxies share common properties like spectral features and scaling relations . Both can be considered early - type galaxies that are passively evolving , at least in the local part of the Universe . </P>
