![]() In the 2000s, it was discovered that the masses of galaxies and their supermassive black holes are related, with the mass of stars in a galaxy around 1000 times greater than the mass of its central black hole. The first quasar was spotted in 1963, and since then, scientists have unraveled the processes that power their immense emission of light. Thus, it is not feeding enough to power a quasar. For example, the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*), consumes so little matter it is equivalent to a human eating a grain of rice every million years. ![]() Powered by supermassive black holes surrounded by gas and dust, some of which is accreted to the black hole, some of which is blasted out at speeds approaching that of light, quasars emit so much light they can often outshine every star in the galaxy that hosts them combined.Īlmost every galaxy is believed to have a supermassive black hole at its heart, but not all of these are quasars. Quasars are some of the most extreme objects in the entire universe. How do supermassive black holes grow with their galaxies? This showed the mass of these early galaxies and their central black holes are related in the same way seen in galaxies observed closer to the Milky Way and, thus, more recent in time. That’s why they’re rigorously tested so you can be sure that the model is as robust as it is beautiful.The observations revealed that the mass of the galaxies is 130 billion and 30 billion times that of the sun, and the masses of the monstrous feeding black holes as 1.4 billion solar masses for J2236+0032 and 200 million solar masses for J2255+0251.
