Lenticular galaxies are a type of galaxy taking the shape of a disc (like spiral galaxies) but which do not have enough active star formation to have spiral arms or a central bar. They tend to be made up of older stars, and their shape means that they are often compared to elliptical galaxies in structure.
Well-known lenticular galaxies in our universe include M84, the Cartwheel Galaxy, and NGC 4866.
