Messier 87 (also known as M87, Virgo A or NGC 4486) is a giant elliptical galaxy. The galaxy is the largest and brightest galaxy within the northern Virgo Cluster, located about 55 million light years away.[3] The galaxy also contains a notable active galactic nucleus that is a strong source of multiwavelength radiation, particularly radio waves.[4] Since this is the largest giant elliptical galaxy near Earth and since it is one of the brightest radio sources in the sky, it is a popular target for both amateur astronomy observations and professional astronomy study. M87 is estimated to have a mass, within 32 kpc of its center, of 2.4 ± 0.6  × 1012 M.[5] Messier 87's diameter is a 120,000 light-years.
