Quasars are only found on the furthest, most out-of-reach corners of the universe, between 2 to 28 billion light-years away. They are thought to be young galaxies as they are being formed.
While it might have a negative impact if one was close (the smallest can exceed the energy output of an entire galaxy, or 1 trillion suns), that will never happen.
If you get near one, you will die. They are the brightest things in our universe.
Uh huh. They are trillion times brighter than the sun, brighter than ten thousand galaxies!
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.

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 (black holes), comets (if they come too close) and hyper nova(only of sun but it will take 5 billion years to do so)
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.
