Messier 89 (M89 for short, also known as NGC 4552) is an elliptical galaxy in the constellation [[Virgo]]. It was discovered by Charles Messier on March 18, 1781. M89 is a member of the Virgo Cluster of galaxies.
Current observations indicate that M89 may be nearly perfectly spherical in shape. This is unusual, since all other known elliptic galaxies are relatively elongated ellipsoids.However, it is possible that the galaxy is oriented in such a way that it appears spherical to an observer on Earth but is in fact elliptical.

The galaxy also features a surrounding structure of gas and dust extending up to 150,000 light-years from the galaxy and jets of heated particles that extend 100,000 light-years outwards. This indicates that it may have once been an active quasar or radio galaxy.[4] It also has an extensive and complex system of shells and plumes surrounding it originated in one or several mergers. <ref>[http://en.wikipedia.org/wiki/Messier_89 Messier 89]]</ref>
