A Pulsar or Neutron Star is the remnants of a collapsed Super Giant, created during a Super Nova. The neutrons are so densely packed that they warp the gravity around the dying star so that any radiation (radio waves) emitted from it doesn't always shine at us. Due to this warping the star becomes more like a light house and we can only see the beam when it is pointing straight at us. This constant on of is like a pulse hence the name Pulsar.
It is the end of a red giant, so a dead star. It died with a supernova, then it shrunk and later became a pulsar. Some people say pulsar are radioactive, but what is surely true is that they send out beams at a strange frequency.
Pulsars are rapidly spinning neutron stars that appear to pulse.
Quasars are the brightest objects in our universe, but are technically not stars although they are star-like, I think they are the oldest objects in our universe. No one is exactly sure of what they are.
it is assumed by the astronomers that quasars were formed just after a few minutes to hours the big bang occured..they have a dense core with unimaginable heat within it & sometimes may contain a black hole inside it"s core.....
A pulsar is the name for a spinning neutron star.

Quasars still exist.
No. Quasars are at the centers of distant galaxies.
Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
Quasars are the unusual type of active galaxy in the universe.
Yes they are. Thanks mainly to the Sloan Digital Sky Survey, more than 200,000 quasars are known.

No. Quasars are at the centers of distant galaxies.
Quasars are thought to be distant super-massive black holes.
The first quasars were discovered in the 1950's
Yes. Quasars are the size of the solar system.
Quasars do not have galaxies in them, quasars are at the hearts of galaxies. All quasars are located in galaxies, as a quasar involves massive amounts of material falling into a supermassiv black hole. Neither of these can be found outside of a galaxy.

pulsar and quasars
Not entirely - although it is believed that quasars are caused by a gigantic black hole.
Quasars are the unusual type of active galaxy in the universe.
Quasars are related to supermassive black holes in the center of galaxies.
