Quasars being most common at a redshift of around 2 means that they were more prevalent in the universe's past. The redshift indicates their distance and age, suggesting that quasars were more abundant when the universe was younger. This redshift value corresponds to a time when many galaxies were undergoing intense star formation and black hole activity, leading to more quasars.
What else can I help you with?
Are quasars the most unusual type of active galaxy?
Quasars are the unusual type of active galaxy in the universe.
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 two keys aspects of quasars?
There the most brightest and distant objects.
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. See related link for more information.
What type of energy do quasars give off?
Quasar actually means quasi-stellar radio sources so we thought that it was giving off radio waves but we did not put into account the redshift that causes the stretching of the wavelength meaning that it most likely gives off microwaves.
Which was discovered most recently DNA atomic power radio waves or pulsars and quasars?
pulsar and quasars
Are quasars the most unusual type of active galaxy?
Quasars are the unusual type of active galaxy in the universe.
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.

Describe two key aspects of quasars?

Do Quasers emit light?
Yes, quasars are the most luminous objects in the universe.

What is the most common solvet?
If you mean 'solvent', water is the most common one.
How red shift connect with universe expanding?
The expansion of the Universe results in the light from faraway galaxies being redshifted. This is called the "cosmological redshift"; it can be compared with the Doppler effect (which also causes a redshift), but the details are somewhat difference.It is an observed fact that most galaxies are redshifted; the explanation that seems most reasonable is that it is caused by the cosmological redshift. This means that space itself is expanding.
How far is the most distant object you can see?
to be honest I'm not quite sure.... i think it's quasars are.
