Nearest Quasar ((hot)) 🔥

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.

Intriguingly, some observations suggest Mrk 231 may contain orbiting each other. The secondary black hole would be about 150 times the mass of our Sun – small for a supermassive black hole but huge for a stellar-mass one. If confirmed, it would be the closest known binary supermassive black hole system. nearest quasar
