How does a galaxy that contains a quasar differ from an ordinary galaxy?

Stars are large spheres composed mainly of hydrogen. Heat and pressure at the cores of as star fuses hydrogen atoms together to produce helium and release energy. Some older stars fuse heavier elements.
A quasar consists of a supermassive black hole pulling in more matter than it can swallow. in-falling matter is heated to billions of degrees, hotter than any star, and excess matter is ejected in jets near the poles at nearly the speed of light. A quasar produces much more energy than any star.

Quasars show a very high redshift, which is an effect of the expansion of the universe between the quasar and the Earth. They are the most luminous, powerful, and energetic objects known in the universe.
Some quasars display changes in luminosity which are rapid in the optical range and even more rapid in the X-rays.
Quasars are believed to be powered by accretion of material into supermassive black holes in the nuclei of distant galaxies.

A quasar is a small (in cosmic terms) object that emits enormous quantities of energy. Quasars consist of a supermassive black hole that is pulling in more mater than it can swallow. As the matter falls toward the black hole it is heated to billions of degrees and emits enormous amounts of energy.

When those black holes were young, they probably generated extremely intense radiation fields similar to the observed behaviors of quasars, or "quasi-stellar radio sources".
So it's possible that long before the Earth formed, our own Milky Way had an "active center" - our very own quasar! We see quasars very far off in the distance, when those galaxies were much younger than they are now.

Individual stars are not detectable at this distance.

In what constellation is the center of the galaxy?
Not "the" quasar, but "a" quasar - there are many. A quasar is associated with a supermassive black hole, and those are generally at the center of galaxies.
A quasar is a type of?
A type of galaxy is probably the answer you are looking for. However, a quasar is actually an active galactic nucleus.
Are all quasars galaxies?
A quasar is not a galaxy. A quasar is an intense energy source associated with a supermassive black hole that is actively feeding. All quasars are located at the centers of galaxies.
Shines brightly in the center of a distant galaxy because of the friction of material spiraling around it?
quasar
What is a quasi-stellar object?
A distant galaxy that appears as bright as a near star.
Galaxy which is thousand times brighter than ordinary galaxy is called?
That must refer to a quasar - however, the claim that it is "a thousand times brighter" is somewhat doubtful. A quasar may seem brighter than it is, (a) because of gravitational lensing, and (b) because the jet is pointed towards us. In any case, a quasar is a small region in a galaxy, which is often brighter than an entire normal galaxy.
Quasar in a sentence?
Astronomers have detected a quasar in a distant galaxy.
Is a quasar a type of galaxy?
No. A Quasar is a Black hole in center of some Galaxies. I think our Galaxy has one of them.
Is a galaxy similar to a quasar and pulsar?
No, not in the slightest sense. A quasar, pulsar, and galaxy are three very different things.
Do Quasars have the energy of 5 million suns?
Quite a bit more than that. A typical quasar is several times brighter than an entire galaxy that has no quasar.Quite a bit more than that.

What is a starlike object outside your galaxy called?
quasar
What is a star like source of energy in the center of a galaxy?
quasar
What galaxy has the brightest center?
A quasar will have the brightest galactic centre.
A quasar is a type of galaxy?
Scientists have only recently decided that a quasar is a galaxy with a relatively new supermassive black hole that has "recently" formed. This isn't certain, by any means; only a few years ago, there was considerable debate about what, exactly, a quasar was. As small as a star, brighter than a galaxy; nothing seemed to make sense.
What is a quasar and what does it have to do with a black hole?
A quasar is a galaxy that is radiating massive amount of radioactive energy. A quasar MAY have a black hole at it's center. A black hole is just dead star that collapsed in on itself.
