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.
Three notable heavenly bodies discovered using radio waves include pulsars, quasars, and the cosmic microwave background radiation. Pulsars, which are rapidly rotating neutron stars emitting beams of radiation, were first identified in 1967 through radio signals. Quasars, incredibly bright and distant objects powered by supermassive black holes, were detected in the 1960s as strong radio sources. Additionally, the cosmic microwave background radiation, a remnant from the Big Bang, was discovered in 1965 using radio waves, providing crucial evidence for the Big Bang theory.

Radio Stars
Quasars A+
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.
No they cannot be mistaken for stars as stars can be seen by the human eye & Quasars cannot.
Quasars emit strong radio waves in addition to other forms of radiation like visible light. These radio emissions can be detected by radio telescopes, which is why quasars are sometimes colloquially referred to as "radio stars."
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.

Around that time, it became clear that quasars were not stars.
Quasars are not actually stars, but extremely energetic and distant objects in the universe, emitting massive amounts of energy.
No, quasars are not the closest objects to Earth. Quasars are extremely bright and distant celestial objects located billions of light-years away, typically at the centers of galaxies. The closest stars to Earth are in our own Milky Way galaxy.
Yes, a average quasar is the size of our solar system
