Quasars are the brightest and most distant objects in the known universe. In the early 1960's, quasars were referred to as radio stars because they were discovered to be a strong source of radio waves. In fact, the term quasar comes from the words, "quasi-stellar radio source". Today, many astronomers refer to these objects as quasi-stellar objects, or QSOs. As the resolution of our radio and optical telescopes became better, it was noticed that these were not true stars but some type of as yet unknown star-like objects. It also appeared that the radio emissions were coming from a pair of lobes surrounding these faint star-like objects. It was also discovered that these objects were located well outside our own galaxy. Quasars are very mysterious objects. Astronomers today are still not sure exactly what these objects are. What we do know about them is that they emit enormous amounts of energy. They can burn with the energy of a trillion suns. Some quasars are believed to be producing 10 to 100 times more energy than our entire galaxy. All of this energy seems to be produced in an area not much bigger than our solar system.

Can quasars be mistaken for stars since they're distant galaxies with an active nucleus at the center of it?
No they cannot be mistaken for stars as stars can be seen by the human eye & Quasars cannot.
Why are quasars called radio stars?
Because quasars was discovered to be a strong source of radio waves.... --> Hi Armstrong SY 2011 - 2012 of MunSci!! Goodluck on your street dance and book nook!!
Distant radio sources that resemble stars?
quasars
What are the brightest objects in the universe called?
They are called quasars. We occasionally observe short bursts of gamma radiation which outshine even quasars temporarily, but astronomers aren't absolutely certain yet what causes them.
Is the dust and gas found between stars called quasars?
No. The clouds of gas and dust are called nebulae. A quasar is a disk of superheated matter falling into an enormous black hole.
What do the largest and brightest galaxies contain?
quasars.
What was proved was not a star in 1963?
Around that time, it became clear that quasars were not stars.
How do you know that quasars are not just nearby stars?
The light from quasars - all quasars - is shifted far to the red side of the spectrum. This means that they are moving away from us, at a very high rate of speed. They cannot be "nearby", for that, and a lot of other sound, scientific reasons.
Are quasars much larger than stars?
Yes, a average quasar is the size of our solar system
Describe how quasars got their name?
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.
