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. [5] 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. [6]

Characteristics

The galaxy is surrounded by an immense stellar halo that extends up to one million light-years in diameter. [7] 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. A jet of highly energetic plasma extends out to 1,700 light-years from its center. The galaxy has 18,700±2,260 globular clusters.
