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
