Quasars
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.

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 are thought to be distant super-massive black holes.
Yes. Quasars are the size of the solar system.
The word quasar refers to a quasi-stellar radio source. Quasars are astronomical bodies that produce vast amounts of energy. The first Quasars have been discovered in the late 1950s.
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.
