Is NGC 4889 a black hole?
At its heart lurks one of the most massive black holes ever discovered. Located about 300 million light-years away in the Coma Cluster, the giant elliptical galaxy NGC 4889, the brightest and largest galaxy in this image, is home to a record-breaking supermassive black hole.
How big is NGC 4889?

Who discovered the Coma Cluster?
Coma was discovered to be an x-ray source in March 1969 by John Meekins et al. Two giant elliptical galaxies, NGC 4889 and NGC 4874, dominate the foreground of Coma. Like other galaxy clusters, Coma’s center consists of a diffuse cloud of hot gas which emits x-rays and is held by the cluster’s gravity.
What is the largest spiral galaxy?
barred spiral galaxy NGC 6872
The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. This enormous spiral is 522,000 light-years across from the tip of one outstretched arm to the tip of the other, making it about five times the size of our home galaxy, the Milky Way.
How far away is the Coma Cluster?
322.9 million light yearsComa Cluster / Distance to Earth
The Coma cluster lies about 330 million light-years away, about seven times farther than the Virgo cluster, in the direction of the constellation Coma Berenices.
What is the age of the Hercules cluster?

How old is NGC 6872?
approximately five billion years old
NGC 6872, also known as the Condor Galaxy, is a large barred spiral galaxy of type SB(s)b pec in the constellation Pavo. It is 212 million light-years (65 Mpc) from Earth and is approximately five billion years old.
When was NGC 4889 discovered?
Unsourced material may be challenged and removed. NGC 4889 (also known as Caldwell 35) is an E4 supergiant elliptical galaxy. It was discovered in 1785 by the British astronomer Frederick William Herschel I, who catalogued it as a bright, nebulous patch.
What is ngngc 4889 used for?
NGC 4889 is also a strong source of soft X-ray, ultraviolet, and radio frequency radiation.
Why was ngngc 4889 not included in the Messier catalogue?
NGC 4889 was not included by the astronomer Charles Messier in his famous Messier catalogue despite being an intrinsically bright object quite close to some Messier objects.
How far is ngngc 4889 from Earth?
NGC 4889 is far enough that its distance can be measured using redshift. With the redshift of 0.0266 as derived from the Sloan Digital Sky Survey, and the Hubble constant as determined in 2013 by the ESA COBRAS/SAMBA/Planck Surveyor translates its distance of 94 Mpc (308 million light years) from Earth.
