NGC 4874 is a supergiant elliptical galaxy in the constellation of Coma Berenices. It was discovered on 11 April 1785 by German-British astronomer William Herschel, who catalogued it as a bright patch of nebulous feature. The second-brightest galaxy within the northern Coma Cluster, it is located at a distance of about 97 megaparsecs (316,000,000 light-years) from Earth.

Characteristics

The galaxy is surrounded by an immense stellar halo that extends up to around ten times the size of the Milky Way Galaxy, somewhere roughly one million light-years in diameter. It is also enveloped by a huge cloud of interstellar medium that is currently being heated by the action of infalling material from its central supermassive black hole.[citation needed] A jet of highly energetic plasma extends out to 1,700 light-years from its center.[citation needed] The galaxy has more than 30,000 globular clusters.
