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 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.
Are quasars extremely luminous but extremely distant objects?
Yes, quasars are extremely luminous astronomical objects found in the distant universe. They are powered by supermassive black holes at the centers of galaxies, making them some of the brightest and most energetic sources in the cosmos.
Do quasars have large or small redshifts?
Quasars typically have large redshifts, which indicate that they are moving away from us at high speeds. This redshift is due to the expansion of the universe and can help astronomers determine the distance and age of quasars.
What does it mean that quasars are most common at a redshift of about 2?
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.
Are quasars the most unusual type of active galaxy?
Quasars are the unusual type of active galaxy in the universe.

How many baby quasars are there in the universe?
Quasars are brightly glowing powerful "engines" of the Universe. Usually they surround black holes and glow when material funnels in. According to Astronomer Maarten Schmidt there are 100 times less quasars now than 10 billion years ago.
Are quasars extremely luminous but extremely distant objects?
Yes, quasars are extremely luminous astronomical objects found in the distant universe. They are powered by supermassive black holes at the centers of galaxies, making them some of the brightest and most energetic sources in the cosmos.
Do Quasers emit light?
Yes, quasars are the most luminous objects in the universe.
Do quasars have large or small redshifts?
Quasars typically have large redshifts, which indicate that they are moving away from us at high speeds. This redshift is due to the expansion of the universe and can help astronomers determine the distance and age of quasars.
Are there a lot of quasars in the universe?
There are about 12,000 known quasars today. I'm sure that as our telescopes get better, that number will go up. As a guess, I would estimate a lot.

What is the new discovery of the universe?
A huge structure of pulsars/quasars which defies the cosmological constant.
Can quasars be found in globular clusters or open clusters?
Quasars are related to supermassive black holes in the center of galaxies.
Why are quasars only found in very distant parts of the universe?
The evidence for the extreme distance is the extreme redshift. Also, in many cases, a coincidence has been found between a quasar and a galaxy.The evidence for the extreme distance is the extreme redshift.
