About C35
Description
NGC 4889 is a supergiant elliptical galaxy in the Coma Cluster, about 308 million light-years away. It is the brightest member of the Coma Cluster and one of the largest galaxies known, with a diameter of roughly 240,000 light-years.
Observing Tips
Visible as a small, round glow in an 8-inch telescope. The challenge is distinguishing it from the many other Coma Cluster galaxies in the field. Best in spring evenings at medium to high magnification.
History
Cataloged by William Herschel on April 11, 1785, as part of his sweeping surveys. The Coma Cluster was one of the first galaxy clusters recognized as a physical grouping.
Fun Facts
NGC 4889 harbors one of the largest known black holes, with an estimated mass of 21 billion solar masses — about 5,000 times the mass of the Milky Way's central black hole.
