What makes Mrk 231 even more fascinating is its "double heart." Data from the NASA Science Hubble Space Telescope suggests the quasar is actually powered by dancing around each other. One black hole is estimated to be 150 million times the mass of our sun, while its smaller companion is about 4 million solar masses. This binary system likely resulted from the merger of two galaxies, a process that fuels the quasar’s intense brilliance.

The nearest quasar is a topic of significant interest in astrophysics, as quasars are among the brightest and most distant objects in the universe. A quasar (Quasi-Stellar Radio Source) is an incredibly luminous object thought to be a distant galaxy with a supermassive black hole at its center. This black hole is actively accreting material, which heats up and releases enormous amounts of energy across the electromagnetic spectrum, making quasars visible from vast distances.
: At its core, the quasar is powered by a supermassive black hole. Intriguingly, observations from the Hubble Space Telescope suggest Mrk 231 may actually host a binary black hole system , consisting of one massive central black hole and a smaller companion orbiting it. | Object | Type | Distance | Notes
Visually, it appears as a faint, fuzzy "star" with a slightly elliptical glow – the quasar point source embedded in a dim galaxy.
Markarian 231 is not just a typical quasar; it is an that is currently undergoing a violent merger process. The Brightest Neighbor: 3C 273 Quasar Host Galaxy
Mrk 231 is not just a point source; it lies at the center of a disturbed, colliding spiral galaxy. The host galaxy is a well-known , meaning it emits most of its energy in the far-infrared, not visible light. This infrared emission is caused by intense starburst activity and dust heated by the quasar.
Observing quasars, especially those that are relatively close by (in cosmological terms), provides valuable insights into the evolution of supermassive black holes and their host galaxies. However, detecting and studying quasars at large distances is challenging due to their faintness and the fact that their light is redshifted (shifted towards the red end of the spectrum) due to the expansion of the universe.
