What is a supermassive black hole and where are they?
It seems that most galaxies have a supermassive black hole in their center. These supermassive black holes have a mass that is millions of times the mass of our Sun; in larger galaxies, billions of times the mass of our Sun. Hence the name "supermassive". For comparison, when a star collapses, it is expected to produce a black hole that has less mass than the star originally had (some mass goes into space, in the supernova explosion), in other words, a few solar masses, or a few tens of them, at most.It seems that most galaxies have a supermassive black hole in their center.

What is a super-massive black hole?
A supermassive black hole is a black hole with a very large mass, millions to billions times the mass of the sun. The supermassive black hole in our galaxy is about 4 million times the mass of the sun.
What is an intermediate black hole?
An intermediate-mass black hole is one that has a mass somewhere between 100 and a million solar masses, i.e., larger than the stellar black holes, but smaller than the supermassive black holes. It seems likely that such holes should exist, but the observational evidence is not yet very firm.An intermediate black hole is one whose mass is somewhere between that of a stellar black hole (a few times the mass of the Sun), and that of a supermassive, or galactic, black hole (millions or billions of times the mass of the Sun).
How are supermassive black holes different from stellar mass black holes?
In their mass. a "stellar black hole" has a few solar masses (a few times the mass of our Sun), while a supermassive black hole (found in the center of most galaxies) typically has a mass of millions or billions times the mass of our Sun.
What is supermassive blackhole?
A supermassive black hole is a huge black hole, usually in the center of a galaxy. All or most galaxies are expected to have such supermassive black holes. Such a galactic black hole typically has over a million times the mass of our Sun; the largest (in large galaxies) have billions of times the mass of our Sun. The black hole in the center of our own galaxy (the Milky Way) is associated with the object Sagittarius A*, and it has a mass estimated at 4 million solar masses.
What is the best evidence for a supermassive black hole in the center of the Milky Way galaxy?
The best evidence for a supermassive black hole in the center of the Milky Way galaxy comes from observations of the orbits of stars near the galactic center. These stars move at high speeds around an invisible object with a mass millions of times that of the Sun, indicating the presence of a supermassive black hole.
The largest known suppermassive blackhole is located in which galaxy?
The largest known SuperMassive Black hole (as of 2011) is located in OJ 287 with a mass of 18 Billion Solar Masses! That is 6 times larger then it's nearest competitor.
What pumps out radiation equivalent to that of trillions of stars but the radiation is emitted from a zone barley larger than 10 times the diameter of the earth's orbit?
That sounds like the description of a quasar. Those are related to active supermassive black holes.
What is located in the middle of our galaxy?
In the middle of our galaxy, the Milky Way, lies a supermassive black hole called Sagittarius A* (Sgr A*). This black hole has a mass of about 4 million times that of our Sun and is surrounded by a dense cluster of stars and gas.
How heavy is a quasar?
A quasar is not a physical object that has weight, as it is a highly energetic and distant celestial object powered by a supermassive black hole at the center of a galaxy. The mass of a supermassive black hole in a quasar can range from millions to billions of times the mass of our sun. However, it is important to note that the weight of a quasar itself cannot be accurately determined due to its complex nature and distance from us.
Is a black hole massive?
A black hole can have anywhere from 2-3 times the mass of the Sun (the lower limit for a stellar black hole), to about 20 billion times the mass of the Sun (the largest known supermassive black holes).
What is the most massive black hole you know of?
Some supermassive black holes - located in larger galaxies - are estimated to have approximately 20 billion times the mass of our Sun. That is more than the mass of a small galaxy - for example, more than the mass of the Small Magellanic Cloud.
