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 more than one, we think. Quasars are so distant that it is difficult to distinguish details about their parent galaxies.
quasars
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.
Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
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.
Yes, quasars are galaxies where the central black hole is turned on and consuming material.
