Its starlike apperance
Quasars are not gone; they are still observed in the universe. Quasars are powered by accretion of material onto supermassive black holes at the centers of galaxies, which can make them appear as some of the brightest and most powerful objects in the universe. However, the number of observed quasars may be influenced by factors such as the current stage of galaxy evolution or observational limitations.
Quasars are the unusual type of active galaxy in the universe.
Typically, a galaxy may contain one or a few quasars. Quasars are incredibly luminous objects powered by supermassive black holes at the centers of galaxies. They are rare and only occur under specific conditions, so it is not common for a galaxy to have multiple quasars.
No, quasars are not part of the solar system. Quasars are extremely distant and energetic objects located in the far reaches of the universe, millions or billions of light years away from our solar system. They are powered by supermassive black holes at the centers of galaxies.
Quasars are thought to be the centers of distant galaxies where supermassive black holes are actively accreting matter. The intense energy emitted by this process makes quasars some of the brightest objects in the universe. Studying quasars can provide valuable insights into galaxy formation and evolution.
quasars
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.

Yes, quasars are galaxies where the central black hole is turned on and consuming material.
