Quasars quasars are very distant objects. The light we see from quasars
has had to travel so far to reach us that it must have been emitted very
soon after the beginning of the universe in order to arrive here today. This
means that quasars give us a glimpse into the past; their light provides a
clue to what the universe was like very soon after it formed |
