lenticular galaxy
(S0, S0 galaxy)
(disk galaxy that has no spirals)
A lenticular galaxy is a disk galaxy (shaped like a disk)
that has no spiral arms, i.e., that is not a spiral galaxy.
The word lenticular means "shaped like a lens" (which is like a lentil).
The Hubble galaxy classification S0 indicates a lenticular galaxy,
which are sometimes referred to as S0 galaxies.
They often have a substantial central bulge.
Their typical properties are much like elliptical galaxies:
substantial cosmic dust, limited star formation,
and aging stars.
