The Question
(Submitted December 22, 1998)
How many quasars do you think there are in the universe?
The Answer
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.
Here is some other information on quasars:
