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 Closest Beacons: Unveiling the Nearest Quasars Quasars, or "quasi-stellar radio sources," are the most luminous and energetic objects in the universe. Powered by supermassive black holes at the centers of galaxies, these cosmic powerhouses emit more energy than hundreds of entire galaxies combined. While most quasars are found in the incredibly distant, ancient universe, a few reside relatively close to our cosmic neighborhood, offering a front-row seat to one of the most violent phenomena in space. The Closest of All: Markarian 231

: 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.

The study of the nearest quasars, like ULAS J1342+0928, is crucial for several reasons:

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.
