quasistellar object Technically, I shall tell you a better answer than the other one!At the very edge of the visible Universe scientists can see extremely bright and powerful objects called quasars. Quasars are about the size of our Solar System and produce more light and energy than 1000 galaxies. Think how incredible that is. A small object, not any bigger than our Solar System making so much power and light that it shines brighter than 1000 galaxies. Why are there no quasars near the Earth? The most distant objects visible in the Universe When we look at quasars which are 10-15 billion light years away, we are looking 10-15 billion years into the past. The quasars near Earth have died down long ago. What could produce so much Power and light? Quasars are probably super giant black holes, which are devouring entire stars. These black holes lie at the center of galaxies, and glow brightly as matter funnels into them.
Initially Quasars where thought to be stars because they we so bright, they also thought they were a lot closer because of their brightness. In the early 1960 Allan Sandage noticed that the "Star" did not act normally and the red shift showed it to be billions of light years away and moving away from us. The First identified "Quasar" was called 3C 273.
Quasars are believed to be collided Galaxies that form a Super Black Hole that sucks all the mass towards it making it Very bright and giving all spectrum's of radiation off.
Because it's quasi-stellar. That's the four first letter of quasi and the two last letters of stellar. There called quasar because they look like stars, from the distance. But they are galaxies that begins to form.
They named it after its starlike appearance!
Bright, distant, powerful, energetic, at the center of the galaxy.
The things that we observe as quasars are believed to be caused by huge black holes.

Light and radio waves.

Its starlike apperance

Quasars still exist.
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.
It most likely got its name from the word used to describe elves, pixies and fairies in general.
Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
