Why do quasars exist?
Well, we don't really know how they are formed, the most likely explanation is: Quasars are formed by enormous redshifts in a star which gives it, it's energy.
What do astronomers use to study quasars?
Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
Can you see quasars down on earth?
Yes only with large telescopes though.
Why are there no quasars left?
Quasars still exist.
Are quasars part of your solar system?
No. Quasars are at the centers of distant galaxies.
Do quasars have a redshift?
Yes, very large redshifts.

What evidence is there that quasars are very far away?
All observed quasars have redshifts between 0.06 and 6.5. Using Hubble's law, it can be shown that they are between 780 million and 28 billion light years away (in terms of comoving distance). See related link for more information.

What are the strengths and weaknesses of the redshift theory?
cons quasars have have large red shift that suggest they are far away as distant galexies some quazars with very high redshifts appear to be interacting with other galexies that have lesser redshift which would suggest that quazars have ann in trensic redshift pros its perfect evidence to show that the universe is expanding

Will astronomers do all the redshifts of the 100 billion galaxies in the universe?
Perhaps in the future astronomers will do all the redshifts of the 100 billion galaxies in the universe.
Are distant objects in space called quarks or quasars?
quasars
Are quasars part of your solar system?
No. Quasars are at the centers of distant galaxies.
Why do scientists think that quasars emit a large amount of energy?
Scientists think that quasars emit a large amount of energy because they believe each quasar has an incredibly large black hole in the center of it. They believe a torus, or disk of dust and gas, has material that falls near the black hole causing it to hear to millions of degrees that accelerates the reaction outward.
How a quasars are formed?
Quasars are thought to be distant super-massive black holes.
