Pulsars are among the most bizarre objects in the universe. They are very small, amazingly dense and spinning round rapidly. Astronomers have been waiting to see whether the supernova in the Large Magellanic Cloud, seen in 1987, will produce a pulsar. Reports from the Cerro Tololo Observatory in Chile indicate that this may well be the case, as Dr Paul Murdin discusses with Patrick Moore.
