147. The telescope zeroed in on two supermassive black holes: a beast as massive as four million suns called Sagittarius A*, which lies at the heart of our Milky Way … On top of that, the most massive known black hole is TON 618, with a mass of about 66 billion suns. One example is at the center of the quasar known as TON 618; the central black hole is an estimated 66 billion solar masses. It is about 5.5 million light-years … A supermassive black hole (SMBH) is the largest type of black hole, on the order of hundreds of thousands to billions of solar masses (M ☉), and is theorized to exist in the center of almost all massive galaxies.In some galaxies, there are even binary systems of supermassive black holes, see the OJ 287 system. An artist's illustration of a monster supermassive black hole at the heart of a quasar in the distant universe.
This reservoir of water is the largest and most distant from Earth that’s yet been detected–it contains enough water to supply 28 galaxies! The biggest known galaxy is IC 1101, which is 50 times the Milky Way's size and about 2,000 times more massive. The gigantic black hole, not counting the giant rings of trapped light orbiting it, is about 23.6 billion miles (38 billion kilometers) across, according to Science News..  Hence the central black hole must be exerting a particularly strong gravitational force. Description. Stellar Giant. Galaxies as we usually think of them tend to be more massive by two orders of magnitude: the Milky Way has a mass of about 1.5 trillion suns.
Scientists consider this to be another example of encouraging evidence that water is prevalent throughout the universe, even during the early formation of stellar bodies. Some astronomers have begun labeling black holes of at least 10 billion M ☉ as ultramassive black holes. As they have simply too … The biggest black hole in the universe is still TON 618 in the Canes Venatici Constellation, 66 billion times the mass of the Sun. TON 618 has a Schwarzchild radius of about 1300 AU so that's a diameter of 2600 AU. The quasar's luminosity is therefore about 3 × 1014 (300 trillion) times the Sun, or over 25,000 times as luminous as all the 100 to 400 billion stars of the Milky Way Galaxy combined, making it one of the most powerful objects in the observable universe.
