NGC 4874 is a supergiant elliptical galaxy. It was discovered by the British astronomer Frederick William Herschel I in 1785, 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 109 megaparsecs (350,000,000 light-years) from Earth.

Characteristics

Template:Section unreferenced The galaxy is surrounded by an immense stellar halo that extends up to one million light-years in diameter.[5] 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.

Supernovae

Three supernovae have been observed in NGC 4874:

  • SN 1968B (type unknown, mag. 17.4) was discovered by Fritz Zwicky on 3 February 1968.[6][7]
  • SN 1981G (Type Ia, mag. 15) was discovered by Miklos Lovas on 2 June 1981.[8][9]
  • SN 2025ilo (Type Ib, mag. 20.6) was discovered by A. Horti-David, K. Sarneczky, and J. Vinko on 26 April 2025.[10]
