How do astronomers measure the mass of a supermassive black hole?

By observing the movement of nearby objects. The gravity of the black hole will accelerate such an object according to Newton's Second Law (F=ma). More specifically, the details of the orbit of a star that moves around the black hole will vary, depending on the black hole's mass.

Why do astronomers hypothesize that there is a supermassive black hole at the center of the milky way?
That's because they actually observed it.
Which is the biggest known black hole in the universe?
The supermassive black hole that hosts the galaxy NGC 1277, in the constellation Perseus, is currently the largest black hole in our visible universe with a mass equivalent to 17 billion suns. In 2012, astronomers have discovered this small galaxy about 250 million light-years from Earth.
What is the most dangerous black hole?
None, really. At least, for us, and now. A black hole can be dangerous if it's very massive (such as a supermassive black hole). But mainly, a black hole would be completely harmless, unless it gets close - and the nearest known black hole is at a distance of about 3000 light-years. Even a supermassive black hole would be harmless at such a distance.
How does a quasar work?
A quasar is believed to have a supermassive black hole at its center. The radiation is emitted outside the black hole's event horizon - from matter that is falling into the black hole.
What led astronomers to believe that this galaxy contained a black hole?
Our galaxy does not contain "a" black hole, it contains thousands, perhaps millions, of them.Astronomers believe there is a supermassive black hole near the center of the galaxy, with a mass of about 4 million solar masses. They reached this conclusion, among other things, by observing objects moving around it. This makes it possible to make an estimate of the mass. Some of the objects are quite near the ... object, whatever it is, and astronomers know of nothing except a black hole that can have such a large mass in such a small space.

What do scientists think is in center of the Milky Way?
The very center is believed to contain a very powerful black hole.
What is the most distant black hole in center of a quasar cal led as?
Quasars have a large black hole, called a "supermassive black hole". The term "supermassive black hole" simply means that it has millions or even billions of solar masses.
Are quasar's different from supermassive black holes?
Yes. In simplistic terms, a quasar is the result of a supermassive black hole. The gravitational attraction of the supermassive black hole on the galaxy, causes the effect of the quasar. See related questions for more information.
