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.

∙ 15y agoIt 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.

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.....

Why are there no quasars left?
Quasars still exist.
Are quasars part of your solar system?
No. Quasars are at the centers of distant galaxies.
What do astronomers use to study quasars?
Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
Are quasars the most unusual type of active galaxy?
Quasars are the unusual type of active galaxy in the universe.
Are quasars possible?
Yes they are. Thanks mainly to the Sloan Digital Sky Survey, more than 200,000 quasars are known.
Why are there no quasars left?
Quasars still exist.
Are distant objects in space called quarks or quasars?
quasars
Are quasars part of your solar system?
No. Quasars are at the centers of distant galaxies.
How a quasars are formed?
Quasars are thought to be distant super-massive black holes.
What year were quasars first discovered?
The first quasars were discovered in the 1950's
Are quasars the size of the solar system?
Yes. Quasars are the size of the solar system.
Do all quasars have host galaxies in them?
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.
What do astronomers use to study quasars?

Which was discovered most recently DNA atomic power radio waves or pulsars and quasars?
pulsar and quasars
Are blackholes and quasars the same thing?
Not entirely - although it is believed that quasars are caused by a gigantic black hole.
Are quasars the most unusual type of active galaxy?
Quasars are the unusual type of active galaxy in the universe.
Can quasars be found in globular clusters or open clusters?
Quasars are related to supermassive black holes in the center of galaxies.
