Why are there no quasars left?
Quasars are not gone; they are still observed in the universe. Quasars are powered by accretion of material onto supermassive black holes at the centers of galaxies, which can make them appear as some of the brightest and most powerful objects in the universe. However, the number of observed quasars may be influenced by factors such as the current stage of galaxy evolution or observational limitations.
What are quasars and where are they found in the universe?
All quasars are located at a great distance from us. Of the quasars discovered, they range from between 780 million and 28 billion light years away. Because of these distances and the velocity of light, we are seeing them early on in the creation of the Universe. They are very rare they have only found about 20 or so.

What is a distant extremely bright galaxy with the black hole at Center called?
The most luminous and distant objects known to science are called quasars and generally accepted to be the nuclei of active galaxies, or in other words supermassive black holes with their relativistic polar jets aimed towards earth.
How do quasars affect the universe?
Quasars are some of the most distant and luminous bodies we can observe. Since we measure them to be incredibly far from our own galaxy, in the order of billions of light-years, astronomers believe that they are several billions of years old as their light would have taken that long to travel to us. Astronomers think that they may be young galaxies as the appear to be incredibly bright balls of accreting gas that probably have black holes at their cores. Because quasars give off characteristic pulses of light at regular intervals, astronomers use them as "standard candles" to measure the redshifts (how quickly they are moving away from us) of other extremely distant objects.
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.

Describe two key aspects of quasars?
Bright, distant, powerful, energetic, at the center of the galaxy.

Are quasars black holes?
A quasi-stellar radio source (quasar) is a powerfully energetic and distant galaxy with an active galactic nucleus which most probably houses a supermassive black hole.Not quite. A quasar is believed to be a disk of superheated matter that is about to fall into a supermassive black hole.

How long have most quasars that are very distant implies that they were formed?
The fact that most quasars are very distant means they were like that when the Universe was quite a bit younger than it is today.
Quasars are the most luminous objects in the known Universe?
Yes Quasar is a ending galaxy which burts with everthing inside it thus the luminousity is the highest.But even when it hasn't bursted it is brighter and more powerful than other galaxy more than a Hypernova too.
