What is the difference between a pulsar and a quasar?

quite a bit. besides both being astronomical bodies, they have very little in common. a pulsar is a neutron star that is rotating and emitting electromagnetic radiation fromit's poles (not rotational poles). The spinning causes the radiation beam to seem like it pulses to a stationary observer, just like a rotating lighthouse seems to. a neutron star is one thing that may form after a star supernovas. the matter collapses in on itself until it is just a mass of neutrons at it's core and not atoms or ions. they are generally on the order of 10 km in diameter.
quasars,on the other hand, are thought to be the result of energy released by matter tumbling into a black hole. they are much larger, about thesize of our solar system. they relase morelight and more of it in the visible region than do pulsars. they also vary in intensity,but not in the extremely periodic way that pulsars do. they appear much more random.
