The icon shows M87, also called Virgo A, the supergiant
elliptical in the heart of the Virgo Cluster.
Some disk galaxies without much structure, i.e. lenticulars, can hardly be distinguished from (and thus are sometimes misclassified as) elliptical galaxies; this has happened in the past to all four Messier lenticulars, among many others.
Elliptical galaxies of Messier's catalog: M32, M49, M59, M60, M87, M89, M105, M110
(Probable) S0 galaxies in Messier's catalog: M84, M85, M86, NGC 5866 (M102 ?)
