1983-07-310.0 rating
First identified 20 years ago, quasars are probably the most dramatic objects in the universe. Though small compared with galaxies, they are extremely luminous, and some of them are so far away that they may lie near the edge of the observable universe. Patrick Moore discusses the latest researches with Dr John Beckman of Queen Mary College.
